Convert ADPCM WAV to MP3
If your recording device records ADPCM .WAVs then you will know that you can’t open these files in sound editors like Audacity. If you search online you will find that most conversion applications like CDex don’t support this format either. I couldn’t find any free or open source program to convert this type of file until I opened it in Windows Sound Recorder. Windows Sound Recorder which comes with Windows is able to convert ADPCM to MP3. First open the file and then choose File > Properties.
Click on the Convert button and then you will see this screen where you can choose your new format.
I set the attributes to match those of the original. If you right-click on the original and select Properties then you can see what attributes it has, my recorder records 8000Hz, 32kbps, Mono.
Now you just save the file with an .mp3 extension and you are now able to open it in your favorite sound editor.





Thanks a lot for this explanation!!!!
Has been really helpfull.
Do you know if there exist something like this in Windows VISTA?
I’ve done it on a XP, and it worked out, but, usually, I have a W VISTA and the recorder in not the same as used to be.
Thanks again…

I really found this posting useful. I also found another site that offers a free converter as well. The website is http://www.wavtomp3converterfree.com/
