Effect descriptions

This app produces a wide range of effects, ranging from minor enhancement to wild modulations. The tube-style distortion effect allows for a variety of tones, from subtle warmth to heavy crunch.

An "8-bit" lo-fi crusher is also included. When active, the 8-bit lo-fi replaces the tube distortion and allows the control of both gain and phase. The result of this bit-crushing is similar to everyone's favorite 80s-style video game console.

The delay effect works much the same as any guitar pedal: short delay-time produces a reverb-like sound; medium settings produce a slap-back echo; and larger delays create "spacey" sound textures. The included "hold" button allows for creative audio experimentation. Delay adjustments are smooth and can be heard as the familiar pitching effect usually associated with analog tape echoes.

Compression is included to help normalize microphone input. It can be toggled off for direct-input cable connections.

This application supports iPhone microphones, Apple-headphones microphones, dock-connector microphones, or guitar-to-iPhone cables.
