Voice bot is a real time channel vocoder. A vocoder takes the spectral information of one sound also known as a modulator and uses it to shape another sound called a carrier. The resulting sound is a bit like a singing robot. Use the microphone to play live or record your own loops for playback, with a few different trigger modes using the keyboard. Further process the sound with a bit and sample crusher, delay and flanger. Play with the built in 25 key dynamic keyboard or using core MIDI with options for MPE. Run voice bot stand alone on iPad and iPhone or as a AUv3 plugin in your favourite host. Connections to other apps are also available through Audiobus and Inter Appp Audio. +++ Microphone input +++ Vocoder with up 128 filter bands +++ Polyphonic carrier source or Mono with glide settings +++ Built in 3 Oscillator carrier source, with saw, square and noise shapes +++ Record or import carrier sample loops +++ Freeze spectrum +++ Bit and sample rate crusher +++ Pitch tracking using Yin algorithm +++ 4 tap stereo delay +++ flanger +++ Multiple sample loop trigger modes +++ 25 key dynamic keyboard +++ Core Midi, Bluetooth Midi, Inter App Audio Midi and AUv3 MIDI +++ Midi CC available for all audio parameters +++ Limited MPE Midi support +++ Modulateble parameters: bands, bit crush, sample crush, delay feedback, flanger mix, vibrator and pitch bend
