Spectro
Spectro is a macOS audio utility that checks music files for fake lossless encoding and helps DJs spot low-quality tracks before playback.
What is Spectro?
Spectro is a native macOS audio utility for checking whether music files labeled as lossless are truly lossless or are compressed files converted into formats such as FLAC, WAV, or AIFF. It is built for DJs, collectors, and other users who want to review audio quality before adding tracks to a library or playing them on larger sound systems. The app scans files on the Mac itself and gives per-track verdicts such as lossless, fake, or medium, along with spectrogram-based analysis to help users understand the result. It supports batch scanning, works offline, and integrates with Finder by applying color tags to files for easier sorting outside the app. Spectro is distributed through getspectro.app and is focused on practical audio-quality verification rather than playback or music library management.

Safety overview
Status: Mostly safe
Spectro’s file analysis and Finder tagging are normal for its purpose as an audio-quality checking tool. It works offline, which reduces privacy exposure because music files do not need to be uploaded to a cloud service. Users should still be aware that changing Finder tags modifies file metadata used for organization, so it is best to test the workflow on a small folder first if you rely on an existing tagging system.
Recommendation: Keep Spectro if you actively check DJ or music-library files for fake lossless audio or want quick Finder-based tagging after scans. If you no longer use it, you can remove it without affecting macOS, though any workflow built around its scan results and Finder tags will no longer be available.
