Supported audio formats
| Format | Full name | Best for |
|---|---|---|
| MP3 | MPEG Audio Layer III | the universal audio format. Every device and app plays it; 192–320 kbps sounds transparent for most listeners. |
| WAV | Waveform Audio | uncompressed PCM audio. Perfect quality and zero decoding cost, but about 10 MB per minute of stereo. |
| M4A | MPEG-4 Audio | AAC audio in an MP4 container, the default for iTunes, Apple Music and iPhone voice memos. Better quality than MP3 at the same bitrate. |
| AAC | Advanced Audio Coding | the successor to MP3, used by YouTube, Apple and most streaming services. Raw .aac streams are less portable than M4A. |
| FLAC | Free Lossless Audio Codec | lossless compression that shrinks WAV by about half with identical quality. The standard for hi-res music collections. |
| OGG | Ogg Vorbis | an open, patent-free lossy format popular in games and on Linux. Good quality, but no native support on iPhone. |
| OPUS | Opus | the most efficient lossy codec available, used by WhatsApp, Discord and WebRTC. Excellent for speech and music at low bitrates. |
| WMA | Windows Media Audio | Microsoft's legacy audio format. Rarely supported outside Windows, so it is usually converted to MP3. |
| AIFF | Audio Interchange File Format | Apple's uncompressed audio format, equivalent to WAV. Used in Logic Pro and professional mastering. |
