Soundhack has released Delay Trio, a collection of three delay effect plugins.

This is a group of three plugins that I developed as class demonstrations while teaching computer music and studio technique at UC San Diego. All of these are derived from the same basic delay algorithm: a hermite interpolated delay line with variable modulation, and a feedback loop with dc blocking and saturation. Pitch shifting is achieved with a dual head crossfading delay (ala Eltro Tempophon/Dennis Gabor/Pierre Schaeffer phonogene) and is decidedly low-fi. The saturating feedback also allows them to be great drone and noise generators.

Delay Trio features

• +delay, classic delay effects.
• +pitchdelay, essentially the same plugin with controls oriented toward pitch shifting.
• +bubbler, a granular delay in which grains are pulled from the delay line with randomized start time, delay time and pitch shift value.

Delay Trio is available as freeware for Windows and Mac (VST/RTAS/AU).
