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
Is M4A better than MP3 for MP4 audio extraction?
Yes. MP4 files typically contain AAC audio. Extracting to M4A preserves the original AAC stream without re-encoding. Converting to MP3 would require re-encoding and introduce quality loss.
What happens to the video track?
Discarded entirely. Only the audio track is extracted and wrapped in an M4A container.
Will metadata transfer?
Basic metadata (title, artist, album) transfers when present in the source MP4.
