Convert WAV to PCM using FFmpeg

FFmpeg has binaries for Windows. It is also available for Linux and other operating systems. That makes it more ubiquitous than GStreamer, which I have used for PCM to WAV conversion in the past.

Here’s the command line for converting a WAV file to raw PCM. If your distribution provides Libav instead, replace ffmpeg with avconv.

ffmpeg -i file.wav -f s16be -ar 8000 -acodec pcm_s16be file.raw

s16be indicates that the output format is signed 16-bit big-endian. The audio rate is changed to 8000 Hz.

You can import and play raw PCM using Audacity.
