Why convert OPUS to FLAC?
- Preserve interviews, testimony, or voice evidence exactly as received, protected by FLAC's built-in audio checksum.
- Meet lossless-input rules of restoration, forensic, and broadcast workflows.
- Protect multi-step editing sessions from stacking lossy generations onto a low-bitrate source.
Tip: A low-bitrate Opus source stays low quality inside the FLAC — the point is preventing further loss and proving integrity, not improving what's there.
