How to extract audio features in java? - Stack Overflow
https://stackoverflow.com/questions/4871291/how-to-extract-audio-features-in-java
The audio in any format is to be converted into pcm format and features like bandwidth, Zero Crossing Rate, Noise Frame Ratio, Pitch Strength and mel Frequency Cepctral Coefficients can be extracted from it. Then a data set is prepared using these features and then various audio classifiaction algoriths are applied to it.

Lab 1 - Basic feature extraction and classification
https://ccrma.stanford.edu/workshops/mir2011/Lab_1_2011.pdf
Create a loop which reads in an audio file, extracts the zero crossing rate, and some spectral statistics. Remember, you did some of this work in Lab 1 - feel free to re-use your code. The feature information for each audio file (the "feature vector") should be stored as a feature array, with columns being the features and rows for each file. 3. featuresSnare = 1.0e+003 * 0.5730 …
