So I’m sitting here working on a video project which the client has specified must be done in PowerPoint. The script is done and the voice over (VO) artist asks me “what format do you want the audio files in?”. I initially say “MP3” but after checking, I find this Microsoft Office article that recommends .m4a with AAC:
The VO artists says “are you sure? I’ve never been asked for that before” and I start do doubt the logic behind the recommendation.
Does anyone know why Microsoft are making this recommendation? Will there be any “nasties” uncovered if I use MP3? And if they go to the trouble of making a recommendation, why not specify recommended encoding parameters such as sampling and bit rates e.g. 16 bit @ 48kHz?
