Masteringo Music Analyzer

Masteringo Music Analyzer is a free browser-based tool for musicians, producers and DJs who want to inspect an audio file before mixing, mastering or planning a DJ set.

It detects tempo and musical key, displays Camelot notation, and provides waveform, spectral balance, spectrogram and loudness views. BPM and key estimates include confidence indicators.

Audio processing happens locally in the browser. No account or audio upload is required.

The analyzer is available directly on the Masteringo website and can be used independently of its separate mastering service. It analyzes audio rather than mastering or normalizing it.

Automatic BPM and key detection can be ambiguous, so results should be checked by ear.
