Audition Deep Dive: REMIX – Automatically rearrange any song to fit any duration

Music is a crucial element for most video productions, supporting the visuals and providing the perfect mood. But our favorite musicians rarely consider the length of our video projects when composing and producing their songs. This means we often need to pay a remix engineer to create a new version of a song, try to tackle it ourselves by finding loopable clips and aligning beats, or giving up and just creating an abrupt fade out at the end of our project. None of these solutions help with budgets, deadlines, or artistic integrity, which is where a new feature in Adobe Audition steps in to save the day.

Audition’s new REMIX tool analyzes your song files, identifying hundreds of loops, transitions, and important segments, and then allows you to quickly remix to any duration. While it’s default settings are often nothing short of miraculous, several parameters allow editors to dial in an ideal new arrangement.

The song file is much longer than the video, but I don't want to just fade out in the middle of a verse.

This song file is much longer than the video, but I don’t want to just fade out in the middle of a verse. Remix will analyze the song and find dozens of potential transitions, then put the pieces together to create a new shorter or longer song to match my desired duration as closely as possible.

To use Remix in your own projects, drop a song clip into an empty track in your multitrack session. Open the Properties panel and click Enable Remix <replace with image of button> in the Remix group. Audition will analyze the recording using a combination of beat detection and source-separation for harmonic identification. This process usually takes around 4 seconds per minute of source music, so it should be very fast. Once analyzed, you can type a specific Target Duration in the panel, or simply drag the zig-zag Remix Clip Handles to adjust the length of your clip and snap to length of your video file.

Drag the Remix clip handles, or type an exact duration to create a remix.

Almost instantaneously, your clip will be remixed with each transition between two segments of the original song indicated by vertical zig-zags, which resemble splices on old tape or film recordings.  Move the playhead a few seconds before one of these transitions and hit play, listening closely as Audition crossfades over the beat.

In green is the Remix clip, while the pink track represents the individual clips and crossfades used to compose the remix.

In green is the Remix clip, while the pink track exposes the individual clips and crossfades used to compose the remix.  Note that the crossfades are represented by white zig-zags in the Remix clip. You will likely work completely with the single Remix clip, but if you right-click and choose Remix > Split Remixed Clip into Segments, you can access each segment or adjust crossfades as you like.

For a lot of music, the default results will sound great and be unnoticeable by listeners. But for well-known or dynamic songs, you may want to try a different arrangement. Open the Remix Properties Advanced section and you’ll see a small selection of options that will adjust your remix.


Depending on the tempo and specific nature of the song you used, the duration may not be exactly precise. You could enable the Stretch to exact duration parameter, applying a real-time stretch to the clip for sample-perfect timing.

Edit Length

Edit Length tells the algorithm to favor shorter segments with more transitions, or longer segments with fewer transitions. If your original song changes fairly dramatically from start to finish, shorter segments and more transitions will allow your remix to flow more naturally. Songs with a consistent structure and style may benefit from fewer transitions, keeping any changes to a minimum.


Features instructs the algorithm to favor Timbre (rhythmic elements) or Harmonic structure when making transitions and crossfades. For electronic or pop music, Timbre will make sure the beat stays locked in place. For choral or softer tracks, Harmonic emphasis will help create smooth blends.

Minimum Loop:

Minimum Loop tells Audition the shortest segment you will permit, in number of beats, and can be useful if the algorithm makes short transitions which might be mathematically ideal, but which sound unnatural to our subjective ears.

Maximum Slack:

Finally, Maximum Slack constrains the remix duration to as close to your target duration as possible. If an exact duration is not necessary, adjusting this parameter can make for better-sounding remixes.


We hope Audition’s Remix tool helps you work faster and generate better results for less effort. It might not put remix professionals out of work just yet, but several DJ’s have already told me they’ll be using it as part of their own workflows. I feel confident you’ll make it part of yours as well.

Notification: Audition CC 2015.1 to remove “Upload to Soundcloud” support

Our upcoming update for Audition CC 2015 will remove the export command “Upload to Soundcloud” and its related functionality.  The Soundcloud Desktop Sharing Kit (Mac Windows) was the integration method recommended when this feature was first introduced, but has been discontinued by Soundcloud for several years, and their server-side implementation has changed such that the tool is now nonfunctional on most platforms.

While we will investigate an update integration for the future, independent developers may be interested in building an Adobe CEP Extension panel and using Soundcloud’s HTTP API to integrate support for Audition.

Audition Basics: Multitrack vs. Waveform editing. What is “Destructive” editing, anyway?

I’ve been meaning to start a blog series covering basic Audition workflows and tools for some time now.  Our documentation and promotional teams do a great job showing off what’s new in each release, but we don’t offer a lot of in-depth training material for Creative Cloud members just getting started.  It is my goal with this ongoing series to cover the topics that help our readers become masters with Audition and audio editing.

Audition is a deep application with a long history and a wide variety of users, so it’s no surprise that its terminology and interface can feel intimidating to artists and professionals from other disciplines.  But apart from a few new words and slight conceptual differences with other production tools, crafting incredible-sounding audio with Adobe Audition can be a simple and fun experience!

Waveform vs. Multitrack

Audition has two primary editing environments.  Multitrack offers a non-destructive clip-based workspace, where you arrange new or imported audio files on a timeline, blending and fading between tracks, and adding real-time processing effects like Reverb or Compression to your clips.  (We’ll cover Compression in another post, so don’t worry about it yet.)  Multitrack editors re-arrange pieces, modify timing, and adjust loudness levels for each piece until perfect, then render their project into a final audio file – often WAV or MP3.  This workflow only uses existing media or creates new media, but never makes changes to the original files.  Multitrack view is often the workspace of choice for video post-production, podcast and radio show creation, and musical composition.

A multitrack session consists of audio clips on a timeline. The clips reference files on disk, but changes made in this workspace are non-destructive and never change files on disk.

A multitrack session consists of audio clips on a timeline. The clips reference files on disk, but changes made in this workspace are non-destructive and never change files on disk.

Waveform view, on the other hand, is a destructive waveform editing workspace capable of in-depth analysis and sample-accurate selections and processing.  Many effects and tools available in this workspace require multiple passes or are not real-time compatible, and result in changes to the actual data recorded in an audio file.  This means that if you make a change to a file in Waveform view and click Save, you are usually overwriting the contents of the file you edited.  This distinction can be tricky for users used to non-destructive NLE or DAW applications to wrap their heads around.

Waveform view offers extensive editing and analysis tools, but any changes made may overwrite the original file.

Waveform view offers extensive editing and analysis tools, but any changes made may overwrite the original file.

Now, why on earth would Audition support modifying your files?  Surely someone must be off their medication to allow such a tool!  Not really.  One of earliest adopters of Audition (and its predecessor, Cool Edit Pro) were radio journalists under exceptionally tight deadlines.  These folks had no time for creating multitrack projects, importing assets, or rendering a mixdown before exporting to the particular flavor of MP2 or WAV their playback automation system supports!  Recording a single report quickly, deleting the “umm”s as fast as possible, and exporting directly to disk enabled them to work as fast as the news happened.  In forensics and archival industries, Audition’s Spectral Frequency Editing environment allows selecting specific sounds and manipulating recordings as easily as using Windows Paint.  Restoring bad recordings into usable or even good, clear audio files can mean proving an alibi in court, understanding Edison’s voice, or hearing a whale’s song.

These two worlds collide when double-clicking a clip in Multitrack opens it in Waveform view.  You can make destructive edits to your assets in Waveform view, that directly change the content in Multitrack view.  In most cases, this is good!  Perhaps there’s a bad hum or background noise, or a production assistant’s cell phone chime occurred during the best take of a scene.  Maybe you want to create an effect where a sound effect speeds up and slows down.  Or you might need to remove some or all of the clicks and pops from a drum loop captured from an old vinyl record.  If you make a change to an original file used in a Multitrack session, Audition will ask if you wish to save the edited file the next time you save your session.i

But if you want to avoid any possibility of destructively modifying your media files, consider working from backup copies of your assets, keeping the originals on a separate storage device. Then you can always restore the file and revert any changes made to an audio file.  Also, before double-clicking a clip to open in Waveform view, right-click and choose Convert to Unique Copy.  This will render the contents of the clip to a new file and relink the clip.  (Similar to Render and Replace in Premiere Pro.)  Any edits performed in Waveform view will only be applied to the copy.

Have a question about editing or mixing audio?  Share it in the comments or via email to and we’ll try to answer it in an upcoming Audition Basics article.



Audition CC and OSX 10.11 (El Capitan)

UPDATE: We have confirmed that the latest beta release of 10.11.1 fixes this issue and allows Audition to run all its plugin effects without any additional problem.  This update also appears to resolve the similar issues found in Audition CS6.  This update should be available to all users Wednesday, Oct 21, 2015.

Attention Mac users:

We recommend users refrain from upgrading to OS X 10.11 (El Capitan) at this time.  Due to changes in application signing, users report crashing with many plugins and native effects.  Additionally, there are many audio devices that will not function without updated drivers, and support has been dropped for many legacy devices by their manufacturers.  Users may also not see the splash screen on launch.

As with most OS upgrades, you may wish to abstain from updating until your applications are confirmed to work correctly, or after any ongoing projects are complete.

The effects that may cause a crash when the UI is displayed are:

  • Analog Delay
  • Chorus/Flanger
  • Convolution Reverb
  • DeEsser
  • DeHummer
  • Distortion
  • Guitar Suite
  • Multiband Compressor
  • Phaser
  • Mastering
  • Single Band Compressor
  • Surround Reverb
  • Tube-Modeled Compressor
  • Vocal Enhancer


MacRumors forums have been maintaining a list of additional software that may not function under El Capitan without developer updates at

Getting started with Podcasting

In honor of International Podcasting Day today, I wanted to share a short guide to creating your own podcast with Adobe Audition. It’s not difficult to get started, and if you’re a Creative Cloud member, you already have almost everything you need!

1. What is your podcast about?
Start with the topic. What do you want to share with others? This might be a passion you already have, or a topic you want to learn more about. Interestingly enough, small, niche podcasts can have better success than shows with a wider variety of topics. Choose something you’re passionate about, and get started!

2. Start recording!
You don’t need a full suite of audio hardware to get started – many popular podcasts are recorded on-the-go with a phone or laptop. Quality of content can be more important than quality of production. There are exceptions, of course, so find a quiet room free from extraneous noises and echoes.  Whether you’re using a high-end Neumann microphone that cost the equivalent of a semester’s tuition at a good university, a low-cost USB microphone, or the microphone built into your laptop, be sure to practice good mic control:  Keep the microphone a consistent distance away from your mouth, and slightly to one side to reduce pops while speaking.  You don’t want to record too “hot” – where the signal peaks are consistently reaching the top of the view – instead keeping your peaks around -12dB to -9dB.  This will prevent clipping and distortion while giving  you some freedom to apply effects and adjust levels later.  Follow along with Adobe Evangelist, Jason Levine, as he walks you through recording a voiceover in Audition.

Should you record in Waveform or Multitrack view? If it's just a single microphone, Waveform view is fast and efficient. Have a co-host or plan to introduce other audio elements into the mix? Use Multitrack view to build your session from pieces.

3. Edit!
Respect your listeners time by trimming out unnecessary umms, ahhhs, and trailing thoughts, but don’t go overboard.  A natural sounding podcast always feel better than one that is obviously edited to bits.  Judge the length of your podcast based on your topic and energy level.  Whether it’s 10 minutes or 2 hours long, you want your listeners to be engaged and it never hurts to leave them wanting more.  Consider spending some time in the Audition Effects Rack dialing in that perfect, custom “sound” that gives your podcast a professional feel and identity.  You can start with some of the presets we’ve supplied, such as Podcast Voice, but be sure to adjust the EQ and Dynamics Processing parameters to bring out the best in your voice.  Also consider adding your show information in the Metadata panel.  The simplest approach is to add the information to the ID3 tab, which will be the most common metadata fields used by podcast players and hosts to make sure listeners can find your show, and know what they’re listening to.  Listen to Mike Russell give away his secrets to great sounding voice recordings in Audition.

Audition ships with many effects rack presets, including many designed just for podcast production!

4. Export
You’ve got to get that podcast down to a size that’s compatible with streaming or downloading!  The first thing you’ll want to do is create a final, compressed version in Audition in mp3 or m4a formats to be compatible with most players.  Choose File > Export > File… and chose your export settings.  Ideally, you want the best quality for the smallest file size.  Personally, I prefer the tongue twister of a format: MPEG-4 HE AAC V2 which sounds incredible.  You can configure this in the Format Settings parameter in the Export File dialog, but feel free to experiment with different codecs and settings and see what works best on the devices you listen to podcasts on right now.  Watch John Lee Dumas explain his basic process for exporting a podcast file after editing.

The Format Settings options allows you to dial in the best quality-to-compression ratio for your content.

The Format Settings options allows you to dial in the best quality-to-compression ratio for your content.

5. Hosting
In order for publishing services like iTunes to carry your podcast, you’ve got to get your files online.  Most podcast directories don’t host the actual audio files themselves, instead linking users to the location you’ve stored your recordings.  If you already have web hosting space, you can upload your files there.  You can upload to a service like YouTube and SoundCloud – if so, you’re done!  Otherwise, you might want to look at services like LibSyn or Spreaker which provide hosting and publishing to directories like iTunes.  You’ll make an account, setup some information about your podcast series, then upload your files.

6. Publishing
If you choose to host the files yourself, you’ll need to inform directory services like iTunes that you are publishing a podcast so that they can list your show and link to your files.  Read the instructions and follow the steps at iTunes Making a Podcast site to build your profile and get your show searchable to their millions of listeners.  Their site walks you through the process of creating art, RSS feeds, and more that they’ll require to keep their site up-to-date as you post new shows and content.

Obviously, this is a basic guide intended to break things down into a few easy pieces.  If you’ve read this far and still want to stake your own claim in the podcasting world, consider the following detailed resources to provide you with the complete workflow and process to recording and publishing a successful podcast:

Happy International Podcasting Day!

One of the nice perks of my role with the Adobe Audition team is getting to chat with podcast producers who use our software to create, edit, and publish their projects. Podcasters are generally gregarious, extremely engaging, and often seem to operate slightly out of phase with the rest of the world, which I love. I won’t bore you with the surveys and demographic reports showing podcast consumption increasing exponentially, and trending to continue growing as technology makes it easier than ever to customize your listening experience while commuting and traveling, but podcasts show no sign of slowing down we need to thank the folks who are making all of that content available to us.

So I’m thrilled to share that September 30, 2015 is International Podcasting Day! This is a day to promote podcasting through education and engagement, and I hope you’ll give a little shout out to your favorite podcast producers today on whatever social media outlet you prefer. Let your friends and family know that you’re a podcast fan, or invite new listeners to your show!

Sneak peek at what’s new in Audition CC 2015.1

Let me get straight to the point.  This upcoming release of Audition CC 2015.1, coming to Creative Cloud users later this year, is guaranteed to perform miracles and work wonders!  We’re revealing the new features online and at IBC in Amsterdam, so read on and check your frequent flyer miles if you don’t already have a ticket.
 (Note: Ability of Audition CC 2015.1 to perform miracles and work wonders not guaranteed.) 


Imagine having a remix artist in your pocket, able to recompose any piece of music in your collection to fit the video or project duration at hand, and willing to do this in seconds and at no additional charge.  Need a 4-minute classic rock track remixed to fit your 30-second car commercial spot?  No problem.  The bride demands her favorite 3-minute slow jam MUST play the entire length of her 20 minute wedding procession?  Audition’s got yer back.

Generate automatic remixes to match the duration of any video or project.

Generate automatic remixes to match the duration of any video or project.

Remix uses a combination of beat detection, content analysis, and the same spectral source separation technology found in our Sound Remover effect, to identify hundreds of transition points in your song, then rearranges the passages to create a new composition.  You can easily see the transition points and adjust the parameters and timing further to craft the perfect remix for your projects!



Speech Synthesis isn’t anything new, remember Speak & Spell or Dr. Sbaitso?  But it’s only recently that technology has progressed where computer voices can sound natural and realistic.  Most modern operating systems offer speech synthesis as an assistive technology, or through arcane command line utilities, but few users are able to take advantage of these features.  Until now.

Create scratch voiceover or sound design tracks using the text-to-speech functionality built into your OS.

Create scratch voiceover or sound design tracks using the text-to-speech functionality built into your OS.

Our new Generate Speech tool provides access to all the languages and voices installed on your system, allowing you to easily paste or type text and quickly generate a realistic (or not!) voiceover or narration track.  Scratch voiceover tracks are an essential element to editing productions quickly and efficiently, replacing them with final recordings later in the production process.  Audition puts the power of these tools into an easy-to-use interface with full control, that’s very fun to use.  (Note: Voices may have license restrictions for commercial or public usage.  Please confirm you have rights to distribute any works containing voices.  A future blog post will share where to license new voices, and even potentially how to create your own custom voices.)



Loudness Correction was le thème du jour at NAB this Spring, so imagine our surprise to find so many of our users were unaware that Audition has had incredible loudness correction tools for several years!  I hope we’ve made it all easier to find in the newly renamed Match Loudness panel!

Ensure your content is broadcast legal, selecting from many international loudness standards, or your own custom requirements!

Ensure your content is broadcast legal, selecting from many international loudness standards, or your own custom requirements!

We didn’t just rename a panel and call it a new feature, though!  New presets for EBU R128, ATSC A/85, and an updated ITU-R BS.1770-3 round out the major standards.  And did someone ask about True Peak Limiting?  Lots of you did!  I’m happy to say we’ve implemented this as well, to ensure that even intrasample waveforms will remain unclipped and legal.  XML Logging makes sure your organization tracks and maintains proof that content was processed prior to broadcast.

Oh?  What’s that you say?  You say having that in Audition is great, but you’re generally working in Premiere Pro and don’t want to drop to Audition just to run a quick audio process?  Well, come here and have a nice hug, because we also implemented this functionality in Premiere Pro and Media Encoder!

Easily ensure broadcast loudness compliance in Audition, Premiere Pro, or Media Encoder! You have absolutely no excuse now!

Easily ensure broadcast loudness compliance in Audition, Premiere Pro, or Media Encoder! You have absolutely no excuse now!


If you’re not already aware of the vast library of third-party services and integration available in the Adobe Addons Marketplace, well, you should be!  The same integrated panels that have been available for Photoshop, Premiere Pro, and many other Creative Cloud applications can now be developed for and used in Audition!  Panels are designed using HTML and Javascript and hook into the Desktop applications, allowing access to files, metadata, and program commands.  Audition has been working closely with technology partners and services used frequently by our users to help build tightly integrated workflows that enable you to access their products without leaving your workstation!  I’ll profile several incredible extensions that you can download from the marketplace over the next several weeks, and interested developers can visit our github page for documentation and sample code to start building your own free or commercial addons.


One of the big topics for Creative Cloud this release is around touch, and Audition has long been a supporter of tactile interfaces.  The Workspace Bar now makes it very easy to switch between task-focused panel layouts, quickly showing or hiding panels and tools that are relevant to your immediate goals.

Audition has included multitouch support for many years, and it’s nice to see Premiere Pro and After Effects catching up with us.  Since Audition CS6 you can use two-finger drag to scroll, two-finger pinch to zoom, and two-finger rotate to scrub playback on supported devices, trackpads, screens, and systems.



Is it me, or did things just get faster?  As your sessions have gotten larger and larger over the years, some bottlenecks were exposed that kept Audition from responding as fast as you were accustomed to.  We’ve identified many areas of improvement to speed up UI updates as well as rendering and playback performance.  New preferences allow you to hide many on-screen elements at small track heights, reducing clutter and increasing speed.  Smarter display of keyframes and envelopes ensure that even the most complex automation won’t slow Audition down!  Keep an eye on future blog posts and Audition updates as performance will be an ongoing mission.


If you’ll be attending IBC in Amsterdam in September, please come visit us at the Adobe booth.  We’d love to show you these features in person, before everyone else gets the chance, and we’re always happy to talk about what our users are creating and the problems they face.

Guest Post: How to make web video sound great with Adobe and Dolby Digital Plus

The following is a guest post from our friends at the Dolby Institute.  With Audition CC and the recent release of Premiere Pro CC 2015 and Adobe Media Encoder CC 2015, you have the ability to export rich stereo and surround audio mixes for your projects in Dolby Digital and Dolby Digital Plus.

How to make web video sound great

By Glenn Kiser, Director, Dolby Institute

Making high-quality video and getting it out for the world to see has never been easier. In the past, it took an army of technicians and artists to tell a story that could reach millions though cinema or broadcast. Now one person can do it with a mobile device and access to streaming digital video services.

And new tools are making it easier than ever to create your video’s final sound mix. The new version of Adobe® Premiere® Pro enables native Dolby Audio™ – Dolby Digital Plus™ audio streams. That means you can mix your video in surround sound, with no additional plug-ins. Now you can create immersive, surround sound content up to 7.1 channels directly in the Adobe Premiere Pro editorial platform or in its companion editorial platform specifically for audio, Adobe Audition®.

I’m going to give you some basic tips for creating a great-sounding audio mix in Premiere Pro and Audition. But remember that you can’t create a great mix if you don’t have great sound to start out with. If you’re a beginner who wants to capture better-sounding videos, start with our basic production guide. You can find more tips on capturing great sound from the Dolby® Institute and Corridor Digital.

Audition CC 2015 now available!

I’m so happy to announce that Audition CC 2015 is now available for download from Adobe Creative Cloud.

I spilled the beans on what was new earlier this year, but now’s your chance to start using the new features for yourself.  Video editors have loved the new Dynamic Link Video Streaming when sending sequences from Premiere Pro – native resolution video streaming with no rendering required.  They’ve also shared that the Full-Screen Video Output is a hit, able to use the standard HDMI, DVI, or VGA outputs on their systems to push the video panel to an external display for ADR, review, or just enjoying a better experience editing audio to picture.

Our radio professionals will really enjoy the return and improvement of Scheduled Recordings and Custom Level Meter Crossovers which enable them to capture streaming or live content without needing to stay at their desk, or customize the color ranges in our level meters to reflect the different standards and requirements of various broadcast organizations.

Users of all sorts will benefit from Automatic Session Backup and Storing Imported Files with the Session, as well as the ability to Relink Media and replace assets in a session without losing any edits, automation, or effects.  Performance improvements to our audio device handling reduce unnecessary warning dialogs and improve stability, especially when mixing and matching devices like USB Microphones!  Advanced users will be able to take advantage of Marker Import/Export and we hope many of you find significant value with the addition of Brazilian Portuguese language support!


You can install the new 2015 release of Adobe Audition through Creative Cloud for desktop or from within Audition by selecting Help > Updates in the menu.

If you have a Creative Cloud membership, you always have access to the most up-to-date version of Audition. Go to the Creative Cloud site to download it. To try out the 2015 release of Adobe Audition CC, you can sign up for a free Creative Cloud membership.  For information about Creative Cloud memberships, visit this page.

A look at Batch Processing filename templates

One of Adobe Audition’s strengths is its ability to perform operations on many files at once, whether transcoding uncompressed WAV files to MP3, ensuring a dozen audio files are of legal broadcast loudness levels, or applying a full recorded favorite consisting of a dozen or more actions.  Audition does this quickly, taking advantage of your multicore or multiple CPU workstations to process multiple files simultaneously, and offers template-based naming and storage so you can organize your files based on their metadata.  We’ve received several comments recently from users who are asking for a crash course on filename templates as the documentation does not delve that deep, so I’m happy to shed a bit more light on that today.
