We just received a new voice recording for our MOH. We received it in .WAV format. I've read all the posts and videos about using the audio converter to convert MP3 files to a .WAV file with the correct codec but in our case the original file is already in WAV format. Can I just upload the WAV file as is or do I need to do something to the WAV file first?
You'll need the files in G.711u and G.729 formats, 8kbit monaural. Adtran has a conversion tool (Windows) for this, for Mac and Linux you can get Audacity from Sourceforge.
