I provide this Windows console utility that transcodes from WAV files to WMA files. By default it uses the voice codec from Windows Media Audio 9 with a very low bitrate to encode voice content but it is possible to use any other Windows Media Audio codec and with a higher bitrate.
When I tried it after having done the last changes it even turned out to be possible to use mp3 files as input which was not even intentional but might be interesting to know. Do remember, however, that you would in that case be transcoding between two potential lossy formats which is normally not a good thing.
Usage: wav2wma -s source -t target [-c codec] [-b bitrate] wav2wma -l Options -s source Source WAV file -t target Target WMA file -c codec Preferred codec -b bitrate Minimal bitrate [bps] -l List all codecs on the system -? Produces this help
