Increase the volume/Remove a part of recorded audio from a recorded session

Many-a-times people face an issue where the volume in a recorded session isn’t loud enough to be clearly audible to everybody.. Similarly there may be times when you may want to remove a part of the recorded audio from the recording.. Here is a solution which although may not be the easiest but definitely a working one for most of the users..

After the recording is finished, pull down the recording source files by adding ‘output/‘ to the recording URL. In the zip that comes down, there will be either a MP3 audio file (if you recorded your audio via an integrated phone bridge) or a FLV file labeled cameraVoip_X_X (if you recorded your audio via VoIP or Universal Voice).

The MP3 file is easy to modify and place back into the zip file, while the FLV may take some work since you will have to extract the MP3 from the FLV and then put it back in the FLV before placing it back in the ZIP. Once you have modified the audio, re-upload the zip to Connect(as Content in Content library) and you will have a new version of your recording with improved audio.

If you need to remove audio, just replace it with silence.

* Word of caution, don’t change the length of the audio file or it will be out of sync with the rest of your recording.

Adobe Connect Offline Recording FLV plays incorrectly; audio track fails to get recognized

Problem :

I have made my Adobe Connect recording offline and when I attempt to play the FLV, the audio doesn’t get recognized by my audio player.

The audio in this file is not recognized even with most standard FLV players. If I attempt to convert it to any other format like MP4, MOV etc, the converted file doesn’t have any audio in that case.


Environment :

Adobe Connect 7.x,8.x,9.x Hosted/Licensed


Reason :

You might sometimes end up creating such an FLV file by making Connect Recording Offline. You are likely to run into this issue if you happen to resize the Adobe Connect  add-in window while your recording is being made offline.

Audio tracks in the offline recording FLV might become unrecognizable partially or completely at varying timestamps within the FLV, in any normal player. The offline FLV might also fail to play correctly sometimes on some standard players like VLC.

Our research indicated that this can be caused to happen because of resizing the Connect add-in window during the process while a recording is being made offline.

To avoid running into this problem of generating a corrupt FLV as a result of your offline recording process, you should ensure you only resize the connect add-in window prior to starting the offline making process. You can set the add-in window size to whatever size/resolution suits your requirement, however you should only do this before the offline making process starts. You can do this before hitting the button of “Proceed with offline recording” that shows up as a prompt in the below screenshot  :

Note that you certainly can minimize and restore the Connect add-in window while making a recording offline, however you should always avoid doing so. The reason behind this is the fact, that the size of the Connect add-in window, while making recording offline, determines the video resolution of the offline FLV being created.

Resizing it during the process, causes inconsistency of video resolution in the FLV file. And this inconsistency, sometimes results in an unrecognizable audio track in the FLV file (especially if this inconsistency is there before any audible audio in the recording).

You may also find such audio inconsistencies if you decide to edit/split the output FLV file into parts.
