Debora Duckett asked,
If files are sent do you prefer .wav or since this will be compressed is .mp3 fine?
I always prefer high quality, high bandwidth sound files whenever possible. If you keep as much detail as possible to the very end then the final, memory optimized (data reduced) audio will sound better.
Most media professionals – music, film, broadcast, photography, etc. – would prefer their source material have more bandwidth than the delivery system.
