FAQ
Which format is best for phones?
M4A (AAC) and MP3 both play everywhere. M4A is slightly better quality at the same size.
Can I convert voice memos?
Yes. iPhone voice memos (.m4a) convert to MP3 for easy sharing.
Is converting MP3 to WAV lossless?
WAV won't add back lost detail, but it stops further loss while you edit.
