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 using some simple tools.

Note: I have also written some batch scripts that will automate some of these processes. You can find them here:

Required Software

Optional Software

  • Mediainfo (this will help you find out the format your files have been encoded in)

Instructions

TS, MTS, M2TS, MOV and MPEG files containing AAC audio

  1. Open the video in MPEG Streamclip
  2. Click on File > Save Track > Save Audio Track
  3. Save as MP4 (if this gives an error, you probably recorded the audio in PCM)
  4. Rename the extension to M4A

TS, MTS, M2TS, MOV and MPEG files containing AC3 audio

  1. Open the video in MPEG Streamclip
  2. Click on File > Save Track > Save Audio Track
  3. Save (this will generate an AC3 file)

TS, MTS, M2TS, MOV and MPEG files containing PCM audio

  1. Open the video in Audacity
  2. Click on File > Export to Other Formats > OK
    • If you recorded the audio as 16 bit PCM audio:
      1. Select Format as "WAV (Microsoft) Signed 16 bit PCM"
    • Else, if you recorded the audio as 24 bit PCM audio:
      1. Select Format as "Other compressed files"
      2. Click Option
      3. Make sure Header is "WAV (Microsoft)" and Encoding is "Signed 24 bit PCM"
      4. Click OK
  3. Save (this will generate a WAV file)
