Free Open Source Software (FOSS)

Below you will find the FOSS available on my GitHub page

Sound Morphing Toolbox (SMT)

The SMT contains contains implementations of two sound models and two sound morphing techniques in Matlab.

The SMT is freely available on GitHub at https://github.com/marcelo-caetano/sound-morphing.

Synchronized Overlap-Add with Fixed Restnthesis (SOLA-FS)

An implementation of the SOLA-FS time-scale modification (TSM) algorithm in Matlab. SOLA-FS performs time stretching and compression in the time domain delivering high-quality results.

SOLA-FS is freely available on GitHub at https://github.com/marcelo-caetano/SOLA-FS.

Sinusoidal Modeling (SM)

An implementation of the standard sinusoidal model in Matlab. This implementation of the SM contains several analysis and resynthesis methods. Parameter estimation via nearest neighbor or quadratic interpolation (linear, log, and power scaling). Resynthesis via overlap-add (OLA), parameter interpolation (PI), and phase reconstruction by frequency integration (PRFI). Finally, SM has a partial tracking algoritm.

SM is freely available on GitHub at https://github.com/marcelo-caetano/sinusoidal-model.
