User Guide

Distort+Delay is a real-time audio processing application from Signals and Stuff that adds high-quality distortion and delay effects to any incoming audio signal. Both acoustic and electric instrument inputs produce excellent results. Performances can be recorded for later playback or sharing with friends.

You can use your iPhone microphone, earbuds microphone, dock microphones, or guitar-to-iPhone cables with this application.

Features

Interface

Grids

The app interface includes two touchable X/Y grids:

X/Y grid

Distort

The orange interface is the distort interface, which controls distortion gain and tone.

Gain (sometimes called drive), is how much the signal should be increased. More gain will result in crunchier distortion.

Tone control changes the texture of the sound. For 8-bit mode, it controls the size of the phase shift. For the classic tube mode, it controls a bandpass filter, much like the Tone control on your favorite guitar pedal.

Delay

The blue interface controls the delay effect. This is the last effect in the signal chain, meaning that any distortion applied will be included in the delay.

The feedback control determines how much of the delay is reintroduced into the signal. This is roughly equivalent to a control on the "repeats" your delay produces.

The delay time control indicates the duration of the delay. A short delay time will produce a reverb sound, and a longer delay time will produce a "spacey" sound.

A special thanks to all of the people who helped test this app and helped introduce me to the crazy worlds of iPhone development and digital signal processing. In no particular order:
