What this machine does
PS-GRN is a granular sampler: a tiny window of a sample is played as a cloud of overlapping grains. Drag across the waveform to scrub, tune the cloud with density, grain size, spread and pitch — and sample two seconds of your own sound with the microphone, processed entirely in your browser.
