Practical Tips

• FLAC compression level 5 (default) offers the best balance of compression ratio and encoding speed.
• Use FLAC for music archival — unlike MP3, no audio data is ever discarded. You can convert back to WAV and get a bit-for-bit identical file.
• Add metadata (artist, album, cover art) during conversion — FLAC has excellent tag support.

Is FLAC truly lossless?

Yes. FLAC uses lossless compression (like ZIP for audio). When decoded, the output is bit-for-bit identical to the original WAV. No quality is lost, ever.

Should I keep WAV after converting to FLAC?

No need. Since FLAC is lossless, you can always convert back to a perfectly identical WAV. FLAC is strictly better for storage.
