Spectrogram View
Examine a 2D map of audio frequencies over time. Customize color ranges, sensitivity, logarithmic scales, and record extended sessions directly to high-resolution JPEGs.
What is Sonance for macOS?
Sonance is an advanced Audio Spectrum Analyzer, Spectrograph, Decibel Meter, and Music Player developed by Rare Works, LLC for macOS. It analyzes live audio feeds from internal microphones, line-in inputs, and USB hardware, or plays tracks directly from your local Apple Music library with native Apple Silicon support.
Important Note Regarding Music File Compatibility & Storage
Sonance is an audio analyzer and local library player, not a universal media player. Due to strict Apple Mac App Store sandboxing limitations, song files must be located within your local user directory and imported directly into your Apple Music library:
- External Drives & NAS: Music stored on external hard drives, USB sticks, or network shares are not supported.
- Streaming & DRM Tracks: Apple Music streaming-only or DRM-protected files cannot be loaded directly into the built-in player. Tip: You can easily analyze these tracks by playing them through your Mac speakers and using Sonance's live microphone input mode!
- Library Import Required: Files dropped into the folder won't appear automatically; they must be fully imported into the macOS Music app library so Sonance can index them.
Experience the Spectrum of Sound.
Sonance bridges the gap between precision hardware telemetry and rich audio entertainment. Whether you are troubleshooting acoustic environments or enjoying your local catalog, get crystal-clear real-time feedback.
Integrated Local Music Player
Play tracks directly from your local Apple Music or iTunes library. Choose between horizontal and vertical player orientations, complete with full shuffle, repeat, and playlist management controls.
Music Library
Select individual songs, multiple songs, or playlists to play. Search or filter through Albums, Artists, Compilations, Composers, and Genres.
Comprehensive Preferences & Customization
Fine-tune every aspect of your analysis pipeline. Adjust FFT windowing functions (Rectangular, Hanning, Hamming, Blackman, Blackman-Harris), bar counts, frame rates, and custom color gradients for Spectral Flames.
