It covers a range of utilities for I/O handling and Time-Frequency Decompositions and soon enough audio source separation methods. Currently supported functionallity :
- WAV/MP3/AAC Reading and Writing
- Time Frequency Methods : MDCT/MDST/PQMF/STFT/FrFFT(Fractional FFT)
- Cepstral Analysis : Uniform Discrete Cepstrum
- Misc Operations : Bark Scaling, W-Disjoint Orthogonality Measure, Gini Index Sparsity Measure, Time-frequency Masking, Noise to Mask Ratio, Psychoacoustic Model (based on non-linear superposition)
For code usage, please refer to each class. Examples are given inside method or in the "main()" call.
