  (Asked by: username_0 on 2014-03-25)
  
  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.
