Extracting audio from video file using VLC

It may be the case that your video cameras capture video in a raw .MTS format, or in another format that you cannot use with ELAN. Or that you just want to use the audio from a video to do your transcriptions. In order to begin working on transcriptions with ELAN while still in the field you can extract an audio track of any video format using VLC (VideoLAN).

Open up your VLC media player and go to the Media menu:

To confirm that you are saving a .wav file with appropriate sample and bitrates, click on the tools icon  to the left of your selected profile. Select the Audio Codec tab and check to make sure you are creating a .wav that has a bitrate of 128 kb/s and a sampling rate of 44100 Hz.

Click SAVE when you have finished

Click Save when you have finished.

Name your file and save it in the same folder as the original video file.
