Towards a musical beat emphasis function

We present a new method for generating input features for musical audio beat tracking systems. To emphasise periodic structure we derive a weighted linear combination of sub-band onset detection functions driven a measure of sub-band beat strength. Results demonstrate improved performance over existing state of the art models, in particular for musical excerpts with a steady tempo.
