I recorded some voice clips for my presentation with Microsoft's Voice Recorder app, but when i tried to insert the audio files into my presentation, PowerPoint claims it only supports WAV format, (despite Microsoft's own website claiming it also supports m4a).

Which is an issue because i need to upload the .PPTX file into my university platform that supports 20MB per file max. (The presentation weights 60MB with the WAV-converted files).

That m4a file was probably encoded with ALAC and not AAC, which is the more supported m4a codec.

Ppt does support mp3's, though. I just inserted some into one of my slide decks both from my phone and on the desktop app. I'd suggest just converting the file.

Thank you!

(But i really gotta state how dumb it is that i can't just pass an audio file i recorded IN a Microsoft app into ANOTHER Microsoft app.)

I could only get as low as 25MB.

Oh well, time to re-record i guess.
