# FLAC/WAV Source Screening and Evidence Handoff

Screen suspected lossless audio, inspect spectral and integer-bit evidence, use reference comparisons only when justified, and deliver a traceable review without claiming authenticity.

## Frequently asked questions

### Does a suspicious result prove fake lossless?

No. Legitimate filtering and older masters can produce the same sharp edge.

### Does no obvious traces prove a genuine source?

No. High-bitrate encodes, gradual rolloffs and unsampled edits can escape screening.

### Does the server API analyze my file?

No. That endpoint accepts synthetic demonstrations only. Real file screening runs in the browser; separate helper tools may upload.

### Can conversion repair a suspected lossy history?

No. Re-encoding into FLAC cannot recover discarded information or establish provenance. Preserve the original and request source evidence.
