GranuLab is a real-time granular synthesizer for Windows. Granular synthesis is the technology of creating complex sound by playing back many short and relatively simple sound fragments with varying parameters.

Just using a sine waveform as base material, and controlling length, pitch and density of grains, several types of sound can be generated.

It is however more exciting to use a concrete sound sample. Good raw material includes speech, instrument or ambient sounds, or indeed synthetic sounds produced with Csound, GranuLab or some other program. In this case, granulation means cutting up the sound into short segments and controlling how these are played back.

The advantage of granulation is that you have control over where each grain begins reading in the soundfile. This means that you can do time-stretching and repitching of sounds in real time, without using computationally intensive FFT analysis / resynthesis.

From a formal viewpoint granulation is a bit of a fudge, and sometimes it is impossible to create a clean effect which has neither echoic nor a metallic or dredgy sound.

But in any case ­ which is just the point ­ any sound can be scrambled beyond recognition with very little effort.
