We currently use lame.exe command line to do .wav to .mp3 conversion. Lame is called by another program and most often, the conversion just works. Except for .wav files recorded in ADPCM format. Does anyone know if there is a command line converter that will throw up an error if the conversion doesn't work - or is that even possible? We would like to know that the automated process couldn't convert the file ... any insight will be much appreciated!
