🎵 FLAC Detective
A lossy file renamed to .flac looks lossless, weighs lossless, and fools every player you own. It can't fool the arithmetic the encoder left behind — and this reads it for you.
MP3, AAC (HE-AAC v2 included), Vorbis and Opus, through independent kinds of evidence. A conviction needs two of them to agree.
Find the fake FLACs in your music library.
A lossy codec throws away the top of the spectrum and never gives it back. FLAC Detective reads each file, spots the fingerprints that loss leaves behind, and tells you which files are real and which are fakes.
pip install flac-detective # needs Python 3.10+
flac-detective /path/to/music # scan a file or a whole folder
Every file gets a verdict, like a traffic light:
✅ AUTHENTIC real lossless → keep it
❓ WARNING borderline → give it a listen
⚠️ SUSPICIOUS probably a transcode → likely a fake
❌ FAKE_CERTAIN definitely a fake → replace it
The scan only reads your files — it never changes anything.
