Podcast hosting platforms like Apple Podcasts, Spotify, and Google Podcasts all support M4A. It's the safe choice for distribution.
For spoken word, 128kbps mono is plenty. Music-heavy podcasts benefit from 192kbps stereo. AudioUtils lets you choose the right balance of size and quality.
Record in the highest quality your setup allows. Convert to your distribution format once, at the end. Every extra conversion degrades lossy audio slightly.
Frequently Asked Questions
How much smaller will the M4A be compared to AIFF?
About 85-90% smaller. A 50MB AIFF file typically becomes 5-7MB as M4A at 256kbps.
Will I lose audio quality?
AAC is a lossy codec, so some compression happens. At 256kbps, the difference from the AIFF original is nearly imperceptible in normal listening.
Can I play M4A on non-Apple devices?
Yes. Android supports M4A natively, and most modern media players handle it fine.
