I have WAV files and need to convert them to PCM (44,1k, 16bit, Mono) format. How can I do this from the DOS console?

This calls for ffmpeg.
C:\enc>ffmpeg -acodec pcm_s16le -ar 44100 -i "input.mp3" outfile.wav
Input #0, mp3, from 'input.mp3':
Duration: 00:03:52.75, start: 0.000000, bitrate: 255 kb/s
Stream #0.0: Audio: mp3, 44100 Hz, stereo, s16, 256 kb/s
Output #0, wav, to 'outfile.wav':
Stream #0.0: Audio: pcm_s16le, 44100 Hz, stereo, s16, 1411 kb/s
Of course it also takes CCITT A-Law, CCITT u-Law and almost anything .wav as input.
To downmix to mono, use -ac 1 (as in audio channels=1).

There is a DOS version of SoX available on its Links page.

i needed to go from one wav format to a PCM wav and i used the simpler command line of
ffmpeg -i "infile.wav" "outfile.wav". YMMV, but it worked great for me. – jrsconfitto – 2012-06-28T19:13:36.957
