LTFAT: A Matlab/Octave toolbox for sound processing

To visualize and manipulate musical signals time-frequency transforms have been used extensively. The Large Time Frequency Analysis Toolbox is an Octave/Matlab toolbox for modern signal analysis and synthesis. The toolbox provides a large variety of linear and invertible time-frequency transforms like Gabor, MDCT, constant-Q, filterbanks and wavelets transforms, and routines for modifying musical signal by manipulating coefficients by linear and non-linear methods. Combined with this the toolbox also supplies a framework for real-time processing of sound signals. It also provides demo scripts devoted either to demonstrating the main functions of the toolbox, or to exemplify their use in specific signal processing applications.
