This directory contains compatibility tests for librosa's core features.
The MATLAB script makeTestData.m generates input/output examples under the data/ directory.
After generating the test data, run pytest from the top-level source directory to perform tests and verify the outputs.
The data files for numerical equivalence tests are generated by the makeTestData matlab program. This relies on a variety of matlab functions which can be downloaded from the following URLs:
- http://www.ee.columbia.edu/~dpwe/resources/matlab/rastamat/
- http://www.ee.columbia.edu/~dpwe/resources/matlab/chroma-ansyn/
The following RASTAMAT functions are required to run the makeTestData.m matlab program:
