Detect MP3-to-lossless transcodes (FLAC, ALAC, APE, WAV) with an 11-rule spectral analysis plus an optional CNN classifier. CLI + Python API + multi-arch Docker. Auto-repairs corrupted FLACs.

FakeFlacFinder is a read-only command-line tool that checks FLAC integrity and looks for signs that the audio was previously compressed using a lossy format such as MP3.

Detect fake FLAC files — find MP3/AAC/Opus transcodes disguised as lossless audio. Fast Rust CLI + web UI.
