A file that claims to be lossless is not always what it seems. Some tracks began life as small lossy files and were later converted into big WAV or FLAC wrappers, gaining size without gaining quality. Spectro checks the audio itself rather than trusting the file name. It scans single tracks or whole folders on your Mac, studies the frequency content, and gives each file a clear verdict so DJs and collectors can spot suspect tracks before they reach a club system.

Key Features

• Give each track a clear lossless, fake or medium verdict based on spectral evidence
• Scan whole folders in batches while working fully offline on your Mac
• Check common formats including WAV, FLAC, AIFF, ALAC, MP3 and AAC files
• Use Finder tags and filters to sort and set aside suspect tracks quickly
• Import library files from DJ software to check a set before you export it
