Why convert WAV to M4A
- Better quality per megabyte. M4A squeezes audio better than MP3. An M4A at 192 kbps sounds about like an MP3 at 256 kbps but takes less space.
- Sharing to iOS users. iPhones, iPads and Macs play M4A smoothly. Handy for AirDrop and sharing with other iPhone or Mac users.
- Apps that require M4A. Some production apps, samplers and iOS shortcuts work better with M4A input than MP3.
Squeezing full quality audio
WAV keeps everything, no detail thrown away. M4A squeezes the audio and removes detail your ear barely hears. At 192 kbps it removes less than MP3 at the same bitrate. At 256 or 320 kbps the loss is tiny. For demos and sharing, M4A is a good choice. Keep the WAV as your master for editing.
Who takes M4A
| Platform | Takes it? | Good to know |
|---|---|---|
| DistroKid | Yes | M4A is on the list. WAV or FLAC still gives the best result. |
| Spotify | No | Wants FLAC or WAV through your distributor. |
| Apple Music | No | Even for Apple: send the 24-bit WAV master, not an M4A. Apple encodes the AAC itself. |
| Bandcamp | No | WAV, AIFF or FLAC only. |

What you get
- An M4A at the bitrate you picked, 44.1 kHz. Making M4A needs Chrome or Edge on a computer, phones cannot do it yet.

- Title, artist and cover art are not copied over.
- The file keeps its name plus what changed, like beat-128kbps-mono.m4a.
