FakeFLAC Detector

Scan your local music library for lossy files masquerading as lossless FLAC

Problem

The poster describes an 'epidemic of fake .flac files' — lossy audio masquerading as true lossless — that ordinary tools cannot identify. The original Python implementation was single-threaded and slow, forcing a rewrite in Go with multithreading. For average music collectors, there is no simple, reliable way to batch-detect and flag these fake files.

Solution

A cross-platform desktop tool that batch-scans music folders and detects whether a FLAC is truly lossless using spectral, bitrate, and encoder signature analysis. It shows results with confidence, offers one-click move/flag of fake files, supports whitelisting false positives, and exports reports.

Users

Local music collectors, lossless audio enthusiasts, library organizers, DJs, audio archivists

MVP

Scan selected folders and flag suspicious FLACs; show spectral screenshot or quantitative metric; highlight results by confidence; batch-move to quarantine folder; export CSV report

Revenue

Free basic version + one-time paid Pro (batch scan, export, scripting, CLI); or affiliate sponsorship on audio tool sites

Why now

Local high-quality audio is seeing renewed interest, yet fake lossless files remain widespread and lack an easy desktop solution. Go/Rust ecosystems make high-performance audio analysis feasible as a solo weekend project.
