Is it still true that .WAV files are the best audio format to use when completing message banking?  If so, why?  Clients often ask me this, and I generally answer that it has to do with compression and sound quality recorded in a WAV file (less compressed/better quality) versus MP3 or MP4 (more compressed/poorer quality).

 

I recognize that a sound engineer may be able to hear the difference between a WAV and MP3/MP4 recording, but is it a difference that truly matters for SGD speech output intelligibility? 

 

Thanks in advance.
