ffmpeg capture audio in raw format I would like to capture audio with ffmpeg in .raw format. Here is what I do to capture in .mp3 format :

ffmpeg -f dshow -t 10 -i audio="virtual-audio-capturer" -y "sound.mp3"


note that I don't want to capture in .mp3 then convert in .raw
Use sound.wav as your output, instead of sound.mp3.  Or if you literally mean raw PCM data with no headers, not just uncompressed, then try

ffmpeg -f dshow -t 10 -i audio="virtual-audio-capturer" -f s16le -y "sound.pcm"


Play it back with

ffplay -channels 2 -f s16le -i sound.pcm


Unless you really need headerless, I'd suggest WAV files for ease of use.  Sample format, rate, and number of channels stored in the file is a Good Thing.
