Installation
To be able to run the audio player (quickPlayer.py), you need to install PyAudio. This is necessary for observing the results.
$ sudo apt-get install libasound-dev portaudio19-dev libportaudio2 libportaudiocpp0
$ sudo apt-get install ffmpeg libav-tools
$ sudo pip install pyaudio
Notebooks:
mc_crop: After putting audio files into "musiccritic" folder, run this. Cropped .wav files together with altered onset annotations will go into "musiccritic_cropped" folder. It crops the unwanted (silence, somebody talking etc.) parts from the beginning and the end of the recordings.
main: First cell installs GuitarSet and unzips to "guitarset" folder. Usage of onset detection and audio player is shown.
chord_segmentation: In chord exercises, rise time of the chords and spacing of individual strings are important. This notebook shows a prototype.
od_comparison: Onset detection algorithms applied on whole datasets. You need "madmom" library for CNN Onset Detector.
