See the Data
This part of the Lab connects your listening experiences to empirical data from psychoacoustic studies. You can:
- explore how acoustic hardness and punch relate to perceived heaviness,
- audition individual stimuli directly from the scatterplots,
- examine how different producers cluster in hardness–heaviness space,
- and inspect additional metrics such as crest factor and loudness range.
The aim is not to reduce heaviness to a single number, but to show where models capture perceptual tendencies, where they fall short, and how they interact with production choices.
Data Explorer
Scatterplots linking hardness, punch, and perceived heaviness. Click to audition.
Explore interactive scatterplots showing the relationship between acoustic models and listening judgements. Each point represents a short segment of audio from the producers' mixes and stems. Click on any point to hear the corresponding audio and see its numerical values.
Producer Overview
Summary metrics and listening suggestions for each producer.
View detailed profiles for all nine producers, including aesthetic characterisations, production profiles, key metrics, and targeted listening suggestions to hear how their approaches affect hardness, punch, and heaviness.

- Start by selecting a subset of stimuli (for example, all choruses, or all guitar-only stems).
- Click on points along a diagonal band: do they sound similarly heavy, or are there perceptible differences?
- Find outliers: segments that are judged very heavy but have only moderate hardness, or vice versa. What production choices explain them?
- Compare producers: do some cluster in a harder or softer region? Do their stems show similar or different patterns?
