rrarrow

rrarrow is the experimental modular audio effect and noise machine for the iOS featuring extended feedback capabilities.

Key features:

• Simplicity. The interface is simplified for faster assembly and more flexible connectivity — you can assemble your effect very fast and control all the processing parameters with the audio signal.
• Feedback capabilities. You can add feedbacks to the audio chain to get some chaotic noise sounds.
• 20 blocks for audio processing:
  • Sine generator. Basic oscillator with sine waveform.
  • Saw and square oscillators.
  • Signal multiplier.
  • Delay.
  • Frequency shifter.
  • Envelope follower.
  • "Lorenz attractor".
  • Quantizer.
  • Sample-and-hold.
  • Reverb.
  • Special Lowpass filter.
  • Clipper.
  • Nonlinear shaper (for self-oscillating circuit).
  • two special waveshaping modules with "fold" and "wrap" distortion.
  • blocks that work with audio files:
  • lookup table. Loads up to 10 seconds of audio file to be used as nonlinear transfer function.
  • Players with/without interpolation and speed control.
  • "scrub" block for semi-random granular file playback.
• Built-in audio recorder. Share the audio file to other applications or AudioShare.
• MIDI support. Assign MIDI controllers to all faders. Supports network MIDI and has a virtual MIDI in.
• Audiobus 2 support. Now you can stream live audio directly to other Audiobus-compatible apps. See http://audiob.us for more information. Works as input and filter. Supports AudioBus State Saving.
• Inter-App Audio support.
• Background audio support: enabled when connected to Audiobus and user switchable otherwise.
