Frequently asked questions
What is the difference between M4A and MP3?+
M4A uses AAC encoding inside an MP4 container. AAC is technically superior to MP3 at the same bitrate — better frequency response, fewer artefacts at low bitrates. MP3 has broader legacy device compatibility. For most modern use, AAC (M4A) is better quality; for maximum compatibility, MP3 wins.
Can I convert iTunes-purchased M4A files?+
iTunes-purchased files purchased before 2009 used DRM (FairPlay) and cannot be converted without the original device. Purchases from 2009 onwards are DRM-free 'iTunes Plus' files (256 kbps AAC) and can be freely converted. Voice memos, GarageBand exports, and QuickTime recordings are always DRM-free.
Will converting M4A to MP3 reduce audio quality?+
Yes — both M4A and MP3 are lossy formats. Converting M4A to MP3 is a 'transcode' — a second generation of lossy encoding. Use the highest available MP3 bitrate (320 kbps) to minimise quality loss. For critical listening, keep the M4A and only convert copies for systems that require MP3.
