If you have an audience video recording with great audio, and you want to share the audio in its original quality without having to upload massive video files, here's instructions on how you can extract only the audio from the video:
Windows instructions
MP4/AVI/MOV/TS files containing AC3 and AAC audio
- Download and install this software called YAMB http://yamb.unite-video.com/
- Clicking on Editing > Click to extract streams from AVI/MP4....
- Click on the Folder icon next to the Input field.
- If audio stream is
- AAC format, click to highlight the AAC file, make sure Extract to Raw Format is selected;
- AC3 format, click to highlight the AC3 file and make sure Extract Audio Stream is selected.
- Select Next.
- The resultant file is the audio of the video in its original quality.
- Repeat steps 1-6 for the rest of your videos.
TS, MTS, M2TS, MPEG2 files containing AC3 audio
- Download and install this software called TSMuxerGUI http://www.videohelp.com/tools/tsMuxeR
- Open the first video file by clicking on Add.
- Uncheck everything except the audio file. The audio file may be one of the following formats AC3, WAV, MP3
- Note if the file contains an AAC stream (in TSMuxerGUI this may appear as "MPEG-Audio"), please use the YAMB method detailed above as this method may result in corrupted AAC streams that do not play correctly in iPhones.
- Select the Demux radio button.
- Click Start Demuxing.
- The resultant file is the audio of the video in its original quality.
- Repeat steps 1-6 for the rest of your videos.
Mac instructions
MP4 and MOV files
- Download and install this software called SimpleMovieX (Free, trial version will work) http://simplemoviex.com/SimpleMovieX/index.var
- Open the video file in SimpleMovieX.
- Click on Edit > Separate Tracks to separate the audio from the video.
- Select the audio track, then go File > Save As (MPEG-4). This will produce an audio MP4 (or MOV if the MPEG-4 option isn't available).
- Rename the file extension from MP4 to M4A and the file should play in iTunes (this step only applies to files whose output is mp4).
- Repeat steps 1-5 for the rest of your videos.
