1. DJ gig preparation — scan your entire download folder before a gig and remove fake lossless files before they cause problems on a professional sound system.
2. Record pool verification — automatically audit newly downloaded tracks from services like DJcity, BPM Supreme, or Beatport and flag any WAV or AIFF files that are actually upconverted MP3s.
3. Sample pack auditing — verify that purchased sample packs and loop libraries from marketplaces contain genuine lossless audio before building sessions around them.
4. Audiophile library QA — scan a personal music collection to confirm which files are truly lossless and which were ripped or downloaded at lower quality and relabeled.
5. Producer intake workflow — check client-supplied stems and reference tracks before starting a mix or mastering project to ensure you're working with real lossless source material.
