rrarrow is an innovative noise machine and modular audio effect designed for iOS. It features extended feedback capabilities, which allow you to create unique and chaotic noise sounds. This app is perfect for musicians, sound designers, and anyone interested in exploring audio processing.

One of the standout features of rrarrow is its simplicity. The interface is designed for fast assembly, making it easy to set up your audio effects quickly. You can control various processing parameters directly with the audio signal, providing a smooth and intuitive experience.

The app includes 20 audio processing blocks that give you plenty of options. You can start with a sine generator, which serves as a basic oscillator with a sine waveform. If you’d like to experiment with different waveforms, rrarrow also includes saw and square oscillators, as well as a signal multiplier.

For creating complex sounds, there's an audio delay effect and a frequency shifter. You can shape your sound further by using the envelope follower and the Lorenz attractor. The audio quantizer and sample-and-hold module add even more depth to your creations.

The app also features an audio reverb effect, a lowpass filter, and a clipper module. If you're feeling adventurous, explore the nonlinear shaper, which is useful for self-oscillating circuits. Additionally, there are specialized waveshaping modules designed for unique distortion effects.

rrarrow allows you to work with audio files through its lookup table feature, which loads up to 10 seconds of audio to be used as a nonlinear transfer function. You can also use players that have interpolation and speed control, along with a "scrub" block for semi-random granular file playback.

Another useful feature is the built-in audio recorder. This makes it easy to share audio files with other applications or AudioShare, allowing you to integrate your sounds into different projects with ease.

MIDI controller assignment is another strong point of rrarrow. It supports network MIDI, meaning you can control all faders using MIDI controllers. This adds an extra layer of flexibility to your audio creation process.

Audiobus compatibility is included as well. You can stream live audio directly to other Audiobus-compatible apps, which works both as an input and filter. The app supports Audiobus state saving, so you never lose your settings. Furthermore, it supports Inter-App Audio, making it simple to integrate with other audio applications.

If you're using Audiobus, background audio playback is supported, but you can also switch it on or off in the app's settings if you prefer.

For those interested in creating complex presets, an iPad2 or iPhone4S or newer is recommended. This app is optimized for both iPad and iPhone 5, ensuring smooth performance.
