Real-time Detection of Musical Onsets with Linear Prediction and Sinusoidal Modelling - EURASIP 2011

Code needed to replicate the results from my 2011 paper in the open access EURASIP Journal on Advances in Signal Processing.

Dependencies

• Modal (and all related dependencies)

Modal Onset Database

The most recent onset database (set of annotated samples) is available from Dropbox

Use

Make sure that the variable data_path in the main __init__.py file corresponds to the directory that your modal onset database is in, and that onsets_path corresponds to the name of the onset database. This defaults to the data folder in the package directory.

Run:

$ python analysis.py

This will create a HDF5 file containing the analysis results called analysis.hdf5 in the same directory.

After making an analysis database, run

$ python results.py

to build a results database.

Running

$ python results_by_odf.py

will create plots of the precision, recall and f-measure results in a directory called images.

Running

$ python results_by_sound_type.py

will print the average F-measure results for each "type" of sound (for each ODF separately). The current sound types are Non-Pitched Percussive, Pitched Non-Percussive, Pitched Percussive and Mixed.
