Analyser
LUFS, true peak, crest, correlation, spectrum, BPM and key — against genre targets and a reference.
The analyser measures your bounce the way streaming services and mastering studios do. It does not listen — it measures. That gives you an honest picture: is the track too loud or too quiet for the genre? Is the bass mono? How much dynamic range is left?
| Parameter | Range | What for |
|---|---|---|
| Integrated loudness | LUFS | LUFSLoudness as people perceive it, to ITU-R BS.1770. Streaming normalises around −14 LUFS, club masters often sit at −8 to −6.More in the handbook → to ITU-R BS.1770 — loudness across the whole track |
| True peak | dBTP, target ≤ −1.0 | True peakThe real peak level between samples. At most −1.0 dBTP for releases, otherwise it distorts after encoding.More in the handbook → between samples |
| Crest factor | dB | Crest factorGap between peak and average in dB. High crest = lots of dynamics, low = heavily compressed.More in the handbook → between peak and average — a measure of dynamics |
| Correlation | −1 … +1 | CorrelationHow similar the left and right channels are: +1 mono, 0 very wide, negative is trouble. In the bass it should stay above 0.9.More in the handbook →; ≥ 0.9 in the bass |
| Band balance | Low / mid / high | Energy below 150 Hz, in between, above 5 kHz |
Loudness by genre
There is no single right loudness target. Ambient and downtempo breathe at −14 to −10 LUFS, house and trance sit at −8 to −6.5, tech house, peak-time techno and drum & bass at −7 to −5.5. Streaming turns everything to around −14 LUFS anyway — louder masters keep their density but lose dynamics. So: master for the genre, not the platform.
