Quick Verdict
Use WAV when…
Use WAV for professional audio production, broadcast, and any workflow requiring maximum software compatibility (DAWs, Pro Tools, broadcast standards).
Use FLAC when…
Use FLAC for music archiving and listening — same lossless quality at 50% smaller file sizes, with better metadata support.
WAV vs FLAC: Feature Comparison
| Feature | WAV | FLAC |
|---|---|---|
| Audio quality | Lossless — bit-perfect reconstruction | Lossless — bit-perfect reconstruction (identical) |
| File size | 100% — uncompressed reference | ~50% of WAV — lossless compression |
| Metadata support | Limited — basic INFO chunks | Excellent — comprehensive tags (ID3-like) |
| DAW support | Universal — Pro Tools, Logic, Ableton, all others | Good — most DAWs support FLAC; a few don't |
| Apple device support | Yes — plays natively on iPhone, Mac | No — requires third-party app on Apple devices |
| Streaming suitability | Impractical — too large | TIDAL and Qobuz stream FLAC for hi-res audio |

Frequently asked questions
Is FLAC truly the same quality as WAV?
Yes, mathematically provably. FLAC is lossless compression — decoding a FLAC file produces bit-for-bit identical PCM data to the original WAV. You can verify this by converting WAV to FLAC and back to WAV, then comparing checksums — they match exactly. The audio is identical in every measurable way.
Which should I use to archive my music — WAV or FLAC?
FLAC — it's the audiophile archival standard. FLAC gives you identical audio quality to WAV at roughly 50% smaller file sizes, plus proper metadata tags (album art, track numbers, genres, dates) that WAV handles poorly. The only reason to archive in WAV is if your editing or playback workflow specifically doesn't support FLAC — which is rare but does occur with some older DAW configurations.
