This software separates a music audio signal (monaural PCM (.wav) format) to two components, "harmonic" and "percussive."

The codes in this repository were used in the experiments of the following paper.

• Hideyuki Tachibana, Nobutaka Ono, Hirokazu Kameoka, Shigeki Sagayama, “Harmonic Percussive Sound Separation Based on Anisotropic Smoothness of Spectrograms,” IEEE/ACM Trans. Audio, Speech and Language Processing, Vol. 22, No. 12, pp. 2059–2073, Dec. 2014.

For academic use, please cite the paper above.

Install boost and fftw3 as follows,

# apt
sudo apt-get install libboost-dev libfftw3-dev

# yum
sudo yum install boost-devel fftw3-devel

cd your_working_directory
git clone https://github.com/tachi-hi/HPSS
cd HPSS/src; make; cd -

Then two programs HPSS_separation and HPSS_smoothness_eval will be generated.

Note that the codes are not refactored sufficiently yet.

• The help message of HPSS_smoothness_eval may not help you.

This program accepts only the monaural (1ch) wav files. If you apply the program to a stereo wav file, it will emit the segmentation fault and halt.

Another implementation of HPSS is availabel below. Note that the algorithm used in the program below is not identical to the one described in the paper above (and the codes in this repository).

GUI version (not coded by me) is available below. Note that the algorithm used in the program below is not identical to the one described in the paper above (and the codes in this repository).
