 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.

Code:

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:
Code:

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.

Thank you, unfortunately one of the two ports was deleted around five years after your offer:

Not sure why this PR had been opened in the first place as it simply describes pretty standard usage scenario for SoX (also known as Sound eXchange).  Adding to this the fact that `audio/adpcm' had long expired, I'm closing it.
