Set-Up

1. Download the MATLAB codec in "main" along with the files in the following link:

2. Paste the Code in a MATLAB file and the audio files within the same folder as the MATLAB file.
3. Declare the path to the said folder.
4. Run.

K-NN-Music-File-sorting

MATLAB's program is capable of sorting music files between two genres (in this case between Japanoise and Japanese Free Jazz) using the K-nearest neighbor algorithm.

Analysis parameters

Three parameters were found to give meaningful and distinguished information between the genres, namely:

• Roughness Mean: Mean of perceptual dissonance, related to the closeness of frequency peaks around frequency bands found in the human auditory system.
• Skewness: Simmetry of Distribution, roughly detecting repetition.
• Root Mean Square: Global energy of the data.
