Audition CC as a Loudness Correction Appliance

While chatting with many of our users at NAB, IBC, and AES, it’s clear that loudness measurement and conformity is a crucial element in preparing their content for broadcast.  The CALM Act in the USA, and similar acts in countries around the world, enforce strict requirements on loudness measurement of content, with many standards such as ITU BS.1770, EBU R128,  ARIB TR-B32, or ATSC A/85.  Unlike the old days, where editors just had to make sure their levels didn’t go into the read, the new standards can require significantly more attention while mixing, or may benefit from post-processing tools which can automate the workflow.

Adobe Audition CC offers several loudness measurement and correction tools, which editors can easily utilize as they work or export their final content.  But this can often be a nuisance, especially in fast-paced newsrooms, and can be prone to the accidental neglectful save without ensuring the content meets station or regulatory standards.  But it’s easy to insert a step in the path from editor to playback where content can be batch processed, and we’re hearing from users who are using a seat of Audition as a Loudness Correction Appliance!  When this was brought to my attention, I wanted to make sure we shared it ASAP as it can literally save time and minimize the possibility of non-standard content making it to the airwaves.

An Audition Loudness Correction Appliance (ALCA) is simply a PC or Mac workstation running Audition, with access to a shared network drive.  As editors copy their finished audio files to this shared directory, Audition can be used to perform a Match Volume pass on files as a batched process, conforming to ITU BS.1770 or any specific loudness measurements desired.  Files can be dragged or imported into the ALCA Match Volume Panel by a lead editor, eager intern, or well-trained bird, and with a single click, individually analyzed and corrected for loudness.  In addition, all content can also be automatically converted to ensure the specific sample rate, bit rate, metadata, and quality settings required for your automation playback systems.  The corrected, conformed files are then exported and saved to a new location, which could be a Watch Folder automating import to the playback system.

To configure your own ALCA, install and activate Adobe Audition CC to the desired appliance workstation.  For this workflow, we only need a single panel visible, greatly simplifying the interface.  Open the Match Volume panel from the Window menu.

You can close the other panels if you like or, and here’s a little tip that works in many Adobe applications, press the tilde ~ key while you’re mouse cursor is over this panel to immediately maximize it.  You can also save this layout as a new Workspace by selecting Window > New Workspace…

This panel is the only one you need open for your Audition Loudness Correction Appliance system.

Within the Match Volume panel, click the Match Volume Settings button (near the top) to show the loudness correction settings.  The default algorithm is ITU-R BS.1770-2 which is compatible with EBU R128.  The default loudness is –23 LUFS, but you could set this to whatever level your station or regional legislation requires.  This will automatically be saved in the application’s preferences such that it becomes the new default.

The Match Volume Settings allow you to specify the type of loudness correction you desire, and customize the specific LUFS value for your needs.

The Match Volume Settings allow you to specify the type of loudness correction you desire, and customize the specific LUFS value for your needs.

Next, you’ll want to add your files to be corrected to the panel.  You can click the Add Files button at the top-left of the panel, double-click in the center of the panel to invoke the Open Files dialog, or drag-and-drop them from Windows Explorer or OS X Finder.  If you click the Compute button (the magnifying glass icon to the left of the Match Volume Settings button) Audition will automatically analyze every file deposited in this panel and calculate its original loudness value and amplitude statistics.  While this isn’t necessary, it can give you a feel for how things are working and provide some insight into the overall process.

These files have been added to the dialog list, and are ready to be processed.  While the example files are MP3, your files can be of any format, sample rate, or channelization settings.

These files have been added to the dialog list, and are ready to be processed. While the example files are MP3, your files can be of any format, sample rate, or channelization settings.

To help automate the workflow, you can setup Audition to automatically process and save the files.  To do so, toggle the Export checkbox at the lower-left corner and click the Export Settings… button when it becomes enabled.  You can configure filename prefix or postfix values here (such as “loudness corrected”) or even choose templates that will draw from the file metadata.  Set the Location value to the directory where you want your finished files to be placed.

In the Export Settings dialog, you can configure the naming conventions, export location, and file format settings you wish for all media.

In the Export Settings dialog, you can configure the naming conventions, export location, and file format settings you wish for all media.

To modify the final file format settings, select the desired format (such as WAV PCM) from the Format dropdown.  To further customize your output, click the Change buttons next to Sample Type (to set sample rate, bit rate, and channelization) or Format Settings (to configure codec specific parameters.)

Sample Type configuration allows you to force all files to specific settings required by your playback system.  For instance you could force all exports to be 16-bit, for legacy automation systems that do not support 32- or 24-bit data types.

For convenience, you can configure Audition to Remove files from the panel upon completion and Close files upon completion to free up resources as each file is processed.  Include markers and other metadata will ensure that the metadata from the source file carries through to the destination file.  If you have ID3 metadata from a source MP3 file, it will even carry through to the new destination file.  BWF bext chunks, (AES-46) CART chunks, iXML chunks, or other specific metadata chunks within a source Wave file will persist through to the destination file as well.  Click OK if you are satisfied.  You should not need to configure these settings again!

With files loaded into the panel, you can now click Run and watch your new ALCA go!  Audition will process multiple files at a time, taking advantage of multiple CPU cores to run analysis and processing in parallel.  To customize how many processor cores Audition can take advantage of, open Preferences > Data and adjust the Maximum number of concurrent file processes value.

ALCA loudness correction in progress!  In this case, all files will be corrected to -17 LUFS, saved in a new destination, and removed from the panel.

This process should greatly speed up loudness conformance while minimizing risk of broadcasting incorrect content, with the addition of ensuring all media meets specific format requirements.  If you setup an ALCA in your edit room, please share your experience and photos!  If you have specific requests for additional functionality, please don’t hesitate to let us know.  I can envision a future where this process is completely automated, utilizing Watch Folders or a similar technology.

 

Learn Audition CC by trying your hand at basic noise reduction

We now have a great intro course for Audition CC that shows you how to fix your audio, easily and efficiently. Free for all CC members, the course includes with downloadable assets. You can can complete the exercises in 30 minutes.

The new course arrives at a good time. We’ve been really pleased at the number of downloads of Audition CC since its release last June. Many of those downloaders are  CC members who are already experienced in audio editing – but there are growing numbers of users, especially video editors, who are still new to the art of manipulating sound. We’re happy to be able to help those folks get started with these new exercises – under the expert guidance of Adobe evangelist Jason Levine. Little known fact: Jason originally came to Adobe as part of the Cool Edit Pro team. That was the product that became Adobe Audition.

Audition CC includes the new Sound Remover and Preview Editor.jpg

Adobe Audition CC includes powerful tools that let you remove sounds easily and efficiently, including really cool Photoshop-style paintbrush, lasso, and healing tools. Unless you shoot your video and record audio in a professional studio, there is a good chance your clips have unwanted background noise in them.

Sometimes the best way to learn to use software is just to dive right in. The new Learn Audition CC – Get started allows you to do just that!

Guide to using 32-bit VST effects with Audition CC via jBridge

It’s a crisp December morning, and I’m looking out my office window at the little corporate building bunny rabbit that lives in the bushes.  He pretty much keeps to himself nibbling on grass, playing with the robins, and hiding from the corporate stray cat that roams through once in awhile.  But every once in awhile, I can hear him talking to me through his big, soulful eyes.  Usually I can dismiss it as the ramblings of a silly rabbit – I mean, c’mon – but this morning he said something that really struck a chord with me.  He mentioned, in a very matter-of-fact manner, that he’s flummoxed with getting his 32-bit VSTs working in Audition CC.  After crafting an e-mail, the standard method of communicating back to psychic bunnies, I figured I’d better share it with our blog readers, even though I’m pretty sure y’all are smarter than this rabbit.

boring picture of bunny

Yes, he looks mild-mannered and cuddly, but he’s a master manipulator, and prone to engineering elaborate pranks. Do not take his advice at face value.  He does have a good ear for mixing a session, though.

 

Quick review of 32 vs. 64-bit plug-ins, and VSTs in general

Until Audition CC was released, Audition was strictly a 32-bit application.  Basically, this means there was a finite amount of RAM Audition was able to utilize – around 4 gigabytes.  As projects have grown bigger, plug-ins and media have become larger, and more high-resolution video files are used in sessions, many users have started to hit this limitation.  After Audition CS6 shipped, we made the decision to update the tool as a native 64-bit application and be on par with most of the other Adobe Creative Cloud tools.  Not only would this allow access to more memory, but it improves performance in many areas and enables features in the latest hardware and operating systems to be fully utilized.

There was a problem, though.  32-bit VST plug-ins are not natively compatible with a 64-bit host application.  While Waves and other large plug-in authors began releasing 64-bit editions of their tools, it turns out there are a lot of folks still using old, often abandoned, 32-bit plug-ins that are unlikely to see an update.  In order to “bridge the gap” between 32-bit plug-ins and a 64-bit host, you’ll need to install a “bit-bridge.”  (Do you see what I did there?  Bit-Bridge.  Bridge the gap.  I got a million of ‘em!)  A bit-bridge acts as a go-between and does all the intermediary math that’s required to fool both the plug-in and the host application to believe that they’re talking to each other.

We got in touch with the folks at jBridge who had been developing and distributing a bit-bridge tool for a few years.  We found jBridge to work very well for most effects we tested, and implemented direct Windows support, though Mac was still in beta when Audition CC wrapped development .  (As a brief aside, the programming quality of your average free VST from the net can vary WILDLY.  Most of the crash reports in Audition over the years have been the result of a plug-in stepping outside its bounds, and much work has gone in to minimizing and preventing these problematic plug-ins from doing too much damage.)  If you’re struggling without your favorite effects, please consider installing and purchasing this tool if you find it works well.

 

Using jBridge with Audition CC on Windows

As noted, Audition CC for Windows implements direct support for jBridge.  Download jBridge and run the installer .EXE file.  Due to OS security measures, you’ll probably need to instruct Windows to run the jBridge processes as an Administrator.  You can find full step-by-step instructions by visiting How to use jBridge – A detailed walkthrough, but basically you’ll need to right-click the three .EXE application files in C:\Program Files\JBridge\ and check “Run this program as an Administrator” in the Properties panel.  This change gives jBridge permission to share plug-ins with Audition and other DAWs.

Launch Audition and select Edit > Preferences > Effects in the menu bar.  Check the preference “Scan 32-bit VST effects using jBridge.” and click OK.

Check this preference to allow jBridge to blend your 32-bit VST plug-ins with your other plug-ins.

Check this preference to allow jBridge to blend your 32-bit VST plug-ins with your other plug-ins.

With this enabled, you’re ready to scan for effects!  Click Effects > Audio Plug-in Manager… from the menu bar and make sure the sure the directory path for the VST effects you wish to use is added.  The default location for 32-bit effects is typically C:\Program Files (x86)\VstPlugins\  Click Scan for Plug-ins and you should see Audition scanning your 32-bit VST effects as if nothing out of the ordinary were going on.  You may see the following warning pop-up, but we know better now, don’t we?

It has no idea what we're about to do!

It has no idea what we’re about to do!

 

Once the scan is complete, you should see a list of all the recognized, valid VST plug-ins found.  Click OK and you should find your effects under Effects > VST in the menu bar.  Hooray!

Using jBridgeM with Audition CC on Mac OS X

As I mentioned before, jBridgeM (jBridge for Mac, in case you’re slow of mind) is the equivalent tool for OS X users, but at the time we implemented support in Audition, the tool was still in beta testing.  While there are much fewer 32-bit VST effects for Mac, we did want to make sure your bases were covered as well.  jBridgeM has the ability to generate new, wrapped VSTs which appear to Audition as a new, 64-bit VST.

First, download jBridgeM and run the installer .PKG file.  Your system may require a restart after the installation is complete.  Go ahead and come on back here when that’s complete.  I’ll wait…  Ready?  Great!  You should now see a new folder in your Applications labeled jBridgeM and inside there is jBridgerM.app  Launching this should present you with  the following dialog:

These options are shown on launch!  No additional clicking necessary.

These options are shown on launch! No additional clicking necessary.

You can generally just use the default options, and click I’ll be using a 64bit VST host.  It will start scanning your installed VST effects and it’s generally best to just sit back and let it do its thing since it tends to pop back into focus with each effect which can be maddening if you’re trying to write a blog post at the same time it scans in the background.  Once it’s complete, it gives you a bit of details as to how many 32-bit effects it found and successfully wrapped.  (It creates a new file on disk, and the host DAWs will see these new files as valid 64-bit effects.)  Next, launch Audition and click Effects > Audio Plug-in Manager… in the menu bar then select Scan for Plug-Ins.  After a few moments, you should see your newly-wrapped plug-ins appear below!  Click OK and access them by selecting Effects > VST in the menu bar or through the Effects Rack panels!

Well done!  If you have additional questions or problems, feel free to visit us in the Adobe User to User forums.  Have a great holiday and new year, and I can’t wait for 2014.  Now, if only that bunny would stop getting songs stuck in my head.  He has such poor taste.

Creating CDs in Adobe Audition: Part 1

Adobe Audition CS6 offers several different ways of creating audio CDs. In this first post, I’m going to show you the quickest, simplest way to create a  multi-track CD from a single file recording.

For this example, I downloaded an hour-long Grateful Dead performance * from archive.org and opened it in Audition.  My first step is to make a selection around each song and create a CD Track Marker.  CD Track markers automatically conform to the minimum increment durations defined by the Red Book Audio CD standard, and are used by Audition when exporting a file to CD.  You can use the SHIFT+M shortcut to create a CD Track marker from any selection, or change the type of existing Cue Markers in the Markers Panel.
