Built by a music collector to solve real problems with Apple's Music.app, it combines library organization, audio analysis, metadata maintenance, file repair, conversion, and advanced music playback in one application. Unlike streaming-focused music services, Local Music Organizer is built around your existing local music collection. It works with Music.app libraries and can also inspect, play, and convert individual audio files without importing them into Music.app. **Music Library Organization** - Find duplicate tracks within playlists and across your Music.app library. - Identify different physical versions of the same recording. - Locate missing files, broken references, and orphaned audio files. - Check album completeness using track and disc numbering. - Discover which playlists contain a particular track. - Compare playlists and explore relationships across your library. - Build a persistent SQLite library index for efficient navigation through large collections. **Smart Shuffle Builder** Create better shuffled playlists with intelligent spacing rules. Prevent the same artist, related musical projects, similar performers, or repeated titles from appearing too close together. Define custom artist groups to separate related voices across different bands and solo projects. The original playlist remains unchanged. **Audio Inspector and Quality Analysis** Examine audio format, codec, bitrate, sample rate, bit depth, channels, and technical metadata. The Audio Authenticity Analyzer examines spectral characteristics to identify possible lossy-to-lossless conversions, suspicious frequency cutoffs, and sample-rate upscaling. A detailed spectrogram helps you investigate recordings rather than relying solely on file labels. **Real-Time A/B Audio Comparison** Compare two physical versions of the same recording using synchronized playback, adjustable timing alignment, optional loudness matching, and live frequency spectra. Switch between recordings while listening to the same passage. The comparison does not modify either source file. **Three Music Players** Choose between three distinctive playback interfaces: - ORIGINAL: detailed spectrum analyzer, waveform, and technical information. - CLASSIC: hardware-inspired audio player with spectrum visualization. - GLASS: customizable 3D spectrum visualization with lighting, depth, and visual effects. Compact Mini Player interfaces are also available. Players share playback state and provide access to playlists, queues, and Audio Inspector. **File Maintenance and Metadata Tools** Inspect audio-file permissions, Finder metadata, filenames, and embedded audio tags. Review and selectively remove supported unwanted metadata, including certain encoder, downloader, and promotional fields. Changes require explicit selection and confirmation. Supported operations include verification and rollback safeguards. **Audio Repair and Conversion** Convert and process a wide range of formats, including FLAC, ALAC, WAV, AIFF, MP3, AAC, APE, TAK, WavPack, DSD/DSF/DFF, SACD ISO, and CUE-based albums. Built-in conversion tools support batch processing, audio normalization, and selected repair operations. Verified output can be retained while original files are preserved, archived, or moved to Trash according to your choice. **Privacy and Control** Local Music Organizer performs its library analysis and audio processing on your Mac. No account is required, and your music collection is not uploaded to a cloud service. File-changing operations are explicitly controlled by the user. **Availability** - macOS 14 or later - Apple Silicon and Intel Macs - Free 3-day full-featured trial - $29.99 one-time purchase - No subscription or automatic renewal Local Music Organizer is designed for collectors who want to understand, organize, protect, and enjoy the music ## An alternative to - [Apple Music](https://macbase.app/alternatives/apple-music): 1 alternative on MacBase - [Audacity](https://macbase.app/alternatives/audacity): 1 alternative on MacBase - [Permute](https://macbase.app/alternatives/permute): 9 alternatives on MacBase ## Get it - Mac App Store: https://apps.apple.com/us/app/local-music-organizer/id6790746382 - Website: https://local-music-organizer-site.pages.dev Listed by [Sergey Belenky](https://macbase.app/@bootrom). ## Similar Music & Audio apps - [TrackEdge](https://macbase.app/apps/trackedge): Hidden AI buttons in your MacBook trackpad.
