Local Music Organizer
An offline Mac music library organizer that finds missing and duplicate files, inspects audio quality, and repairs or converts audio.
About Local Music Organizer
Local Music Organizer is a macOS music organization tool for collectors who carefully manage offline music libraries. It scans the library read-only to locate missing files and duplicate tracks, map playlist relationships, check metadata, and compare physical versions; the audio inspector shows codecs, bit depth, sample rate, spectrum plots, and afinfo raw output, while playback adds real-time spectrum analysis. Its built-in offline engine repairs and converts standalone audio files and supports batch normalization of sample rate and bit depth. Everything runs locally, with no audio or library uploads, and important changes run only after explicit confirmation. It does not modify the Music.app database, and Apple Music subscriptions and streaming content are unsupported.
