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.
