Abstract
A computer implemented method for analysing sounds, such as audio tracks, and automatically classifying the sounds in a space in which arousal is one axis and valence is another axis. The location of a sound or track in that arousal-valence space is automatically determined using a computer implemented system that analyses, measures or infers values for each of the following base feature parameters: harmonicity, turbulence, rhythmicity, sharpness, volume and linear harmonic cost, or any combination of two or more of those parameters.

A computer implemented system configured to analyze sounds, such as audio tracks, and automatically classify the sounds in a space in which arousal is one axis and valence is another axis;
- and the location of a sound or track in that arousal-valence space is automatically determined by analyzing, measuring or inferring values for each of the following base feature parameters:
- harmonicity, turbulence, rhythmicity, sharpness, volume and linear harmonic cost, or any combination of two or more of those parameters.
