GRDelay is an AUv3 granular random delay plugin that generates up to 16 stereo grains from input audio in real-time. It offers unique sound design capabilities by allowing users to randomize grain shape, delay time, and pitch-shifting to create complex textures and shimmer-like effects. ## Key Features - **Granular Delay Engine**: Generates up to 16 stereo grains of sound in real-time from delayed input audio. - **Randomization Controls**: Allows for the randomization of grain shape, delay time, and pitch-shifting to produce unusual textures. - **Cascading Output**: Supports routing the output from one grain into another for complex signal processing. - **AUv3 Compatibility**: Functions as a standalone application or as a plugin within AUv3-compatible hosts like Logic Pro and GarageBand. ## Who is it for? Music producers and sound designers looking for unique, experimental delay and texture-generation tools within AUv3-compatible hosts. ## Links - [App Store](https://apps.apple.com/us/app/grdelay/id6757957948?uo=4) - [Full Intelligence Report](https://marlvel.ai/apps/grdelay) --- *This is an overview report.
