Settings each format uses
- MP3: LAME high-quality VBR (-q:a 2, around 190 kbit/s)
- AAC and M4A: AAC at 192 kbit/s
- OGG: Vorbis quality 5 (around 160 kbit/s)
- WAV: uncompressed 16-bit PCM
- FLAC: lossless
Choosing a format
For sharing and playback anywhere, MP3 is the safe choice. For editing or archiving, keep a lossless copy (WAV or FLAC). Converting between two lossy formats (for example AAC to MP3) adds a second round of compression; at these settings most listeners won't hear it, but it can't be undone.
