02 / what you get
What happens to your data
Kept
- Sample rate and channels (mono, stereo, even 5.1 surround) are read as they are
- Hi-res FLAC files (24-bit, 96 kHz) are supported
- Saved as Opus at 128 kbps, which usually sounds as good as a much larger MP3
- Title, artist and album tags are carried over
Good to know
- Opus always runs at 48 kHz, so other sample rates are converted.
- Older players and some Apple apps cannot open .opus. Use MP3 or M4A there.
- Embedded cover art is not carried over. Only the sound is converted.
- Lossy compression permanently removes some detail. Keep your original if you want to archive the recording.

FLAC vs OPUS
FLAC
A FLAC file compresses audio without losing any quality (lossless) — smaller than WAV, but still identical to the original when played back. The go-to format for audiophiles and music archiving.
Used in: Music archiving · Audiophile listening · High-quality downloads
OPUS
An OPUS file uses one of the most efficient audio codecs available today — smaller files than MP3 at equal quality, especially good for voice. It's what WhatsApp voice messages and Discord calls use under the hood.
