Abstract:
1. A music-analysis tool comprising: a music audio track selection module that is configured to select at least one music audio track from a corpus of music audio tracks; an acoustic-features module that is configured to calculate acoustic features of the music audio track; a vector-quantization module that is configured to vector quantize the calculated acoustic features; a geometric-features module that is configured to calculate geometric features of the music audio track based on the vector-quantized acoustic features, wherein the vector-quantization module is further configured to vector quantize the calculated geometric features; a cross-product module that is configured to take a cross-product of the vector-quantized acoustic features and the vector-quantized geometric features to yield a joint acoustic-geometric feature vector for the music audio track; and a playlist-selection module that is configured to select a playlist of music audio based on the joint acoustic-geometric feature vector for the music audio track.
