Abstract: A method of characterising chords in a digital music file comprises: receiving a portion of music in a digital format and for a first time interval in the music, a value of a chord feature from a set of chord features is predicted using a conditional Autoregressive Distribution Estimator (ADE). The ADE is modified using the predicted value for the chord feature and the modified ADE is used to predict a value for a different feature of the chord from the set of chord features. These operations are repeated until a value for each of the features in the set of chord features has been predicted for the first time interval. They are then repeated for subsequent time intervals in the portion of music.

Abstract: A method of selecting points in a music audio signal for placement of a sound effect comprises searching for points in the music audio signal as potential candidate placement points based on one or more criteria such as melspec or CQT. An onset strength time series for the music audio signal is determined and boosted at points found by the search. Points are then selected from the boosted onset strength time series with a value larger than a predetermined threshold as candidate points for the placement of the sound effect.
