iVoxel is not only an amazingly sounding vocoder - the unique concept of iVoxel turns this vocoder into a singing machine. iVoxel is a combination of a voice optimized synthesizer and a vocoder. The vocoder part is based on the Matrix vocoder from VirSyn used by many famous artists - one of them the well known german group Kraftwerk. The channel filters used by iVoxel are based on the Sennheiser Vocoder VSM201 resulting in a rich and fat analogue sound characteristic. The pitch follower and automatic tuning let you sing correct to a selectable scale. You can use iVoxel in many different ways: As a realtime vocoder talking into the microphone while playing tunes on the keyboard. The sound character of your voice can be changed in many different aspects like pitch, gender or breath noise. Use it to sing over your favorite iTunes song ! Record the analyzed spectrum of phrases and words from your own voice. Then use this voxel to play with your own voice on the keyboard or with the build in sequencer. Nearly 300 hundred prerecorded voxels are already included. iVoxel is Audiobus compatible and can be used in the Input, Filter and Output slots in the Audiobus signal chain. The carrier signal and the vocal signal can now be fed by any Audiobus compatible Apps. The output of your creations can be recorded to an audio file which you can use with other Apps and programs for further processing. Features: • Realtime analysis/resynthesis of your voice • 20+2 Channel vocoder • Pitch Follower and automatic tuning correction to selectable scale • Realtime pitch to MIDI Note converter • Voice spectrum recorder (voxels) • Nearly 300 prerecorded voxels included • Play your vocoded voice live on keyboard.

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
