Analysis
Measurements, not promises
Every number with its dataset and measurement method.
- 99,6% BPM exact (±0.05 BPM)
- purchased Beatport tracks
- 97,4% First beat off by 10 ms at most
- purchased Beatport tracks
- 97% Tempo within ±4% (Acc1)
- Raveform, EDM test set annotated by humans
- 93% Key matches the majority of three established key tools
- purchased tracks; 96%, where all three agree
- 84,7% Sections with the right role
- Structure suggestions on separate EDM tracks
- 31,2Tracks/min Analysedurchsatz
- 16-thread PC, up to 6 analyses at once (previously 16.1)
Beatgrid: purchased Beatport tracks on which Lexicon and Mixed In Key set the same grid to within 20 ms. Sonodex gets the BPM exactly right on 99.6% and places the first beat within 10 ms on 97.4%. Every grid is also checked against the kick.
Tempo: 97% of the Raveform test part is right to within ±4% (Acc1). Raveform is a set of EDM tracks annotated by humans [1]. Since 4.8, Sonodex detects drum & bass at full tempo, for example 174 instead of 87 BPM.
Key: on 93% of the purchased tracks, Sonodex determines the same key as the majority of three established key tools; where all three agree, it is 96%. 97% are harmonically compatible (same key or a neighbour on the Camelot wheel: fifth or relative key). Eight neural networks and a chroma model determine the key; Sonodex always gives a key.
Structure and energy: the local structure suggestions give 84.7% of sections the right role. The energy rating of analysis version 6 scores a track by its strongest sections.
Speed: “Automatic” analyses up to six tracks at once, depending on your processor. On a PC with 16 threads, throughput rose from 16.1 to 31.2 tracks per minute, almost twice as fast.
All values are our own measurements from November 2026 with the analysis of Sonodex 4.8 and later.
