Which format
| Format | Type | Use it for |
|---|---|---|
| MP3 | Lossy | Universal compatibility. Anything made after 1998 plays it. |
| M4A (AAC) | Lossy | Better sound than MP3 at the same bitrate. Apple devices, modern everything. |
| Opus | Lossy | The best quality per kilobyte by a distance. Speech at 32 kbps is genuinely fine. |
| OGG (Vorbis) | Lossy | Patent-free. Game engines and older open source software. |
| WAV | Uncompressed | Editing and mastering. About 10 MB per minute in stereo. |
| FLAC | Lossless | Archiving. Roughly half the size of WAV with nothing thrown away. |
Bitrate, honestly
For music, 192 kbps MP3 is transparent for most people on most equipment, and 256 is comfortably past the point of diminishing returns. For speech, 96 kbps is plenty and 64 kbps Opus is still clear. Converting a 128 kbps MP3 to 320 kbps does not add anything back, the detail is already gone, and you just get a bigger file holding the same sound.
Common questions
Does converting MP3 to WAV improve the quality?
No. It removes the compression from the container but nothing is recovered. It is only useful when a tool refuses to accept MP3.
Is converting between lossy formats bad?
It loses a little each time, because each encoder throws away what it thinks is inaudible and they disagree about what that is. One hop is fine; repeated round trips are not.
What is the safest all-round choice?
MP3 at 192 or 256 kbps. Nothing anywhere will refuse to play it.
