Fragment is a collaborative additive / spectral / granular live-coding web. platform, the spectrum is created by a live GPU script, the generated visual is then converted to audio by an additive or granular process.
Fragment is able to produce high-quality fast additive and granular synthesis simultaneously with re-synthesis support, it has many features making it a bliss to produce any kind of sounds or visuals.
This is a demonstration video of a multitude of sounds created within Fragment, mostly additive synthesis (90% of them) but some parts are granular, this also demonstrate granular re-synthesis at 6:54 with more than 400 layered grains and vocoder effects at 3:11, some parts (the beginning) use distributed synthesis mode and are able to play more than 1200 simultaneous partials on a i7 CPU with 4 synthesis server.
Small amount of reverb/delay effect added inside Renoise DAW, low-pass filters are used on granular sounds because Fragment play the grains sample as-is, MIDI sequences are coming from Renoise.
