 Howto: Listen to IMA ADPCM .wav files on your FreeBSD box
I hope this howto will spare someone the headache it caused me this afternoon.

So you have a .wav file from your voicemail system (or wherever) that you discover is in IMA ADPCM format.


user@someplace$ file VoiceMsg.wav VoiceMsg.wav: RIFF (little-endian) data, WAVE audio, IMA ADPCM, mono 8000 Hz

Install two ports:

    * /usr/ports/audio/sox
    * /usr/ports/audio/adpcm

Now use sox to convert it to a suitable format. In my case I chose:

user@someplace$ sox -i VoiceMsg.wav -s out.wav

The -s option created a MS PCM file for me, but do whatever you'd like. See sox man pages for many more options, of course.

P.S. This was tested and confirmed on a FreeBSD 5.4-RELEASE box.
