Mod Phon has released Voxen, a voice synthesizer for the iPad. A spokesperson had this to say about it,

"Voxen lets you synthesize singing voices. Any voice, not just the few voices that someone else designed into it, plus voices that no vocalist can sing. No pitch shifting. No time warping. Just good ol' pure synthesis.Voxen is based on the voice synthesis technology used by speech scientists and psychoacousticians around the globe. Even though it can be great fun to play with, it is not a toy. Voxen is intended for musicians, DJs and producers who are looking for new and different sources of sounds."

• Keyboard range of more than ten octaves
• Three X-Y touchpads
• Twenty-eight vertical linear knobs
• Choice of dark or light background colour

TECHNICAL DETAILS

Voxen is a polyphonic formant synthesizer. There are three banks of knobs which control, respectively, the voice, the voice envelope and the formants. The six voice knobs control provide a modified Klatt 1989 voicing source. The ten voice envelope knobs control master amplitude and ADSR envelope for the voicing source and for a separate aspiration source. The remaining twelve knobs control the centre frequencies and bandwidths of the first four formants and the centre values and differences (spread) for a nasal formant/antiformant pair.

Each of the three X-Y touchpads controls a pair of parameters, f1 & f2, b1 & b2 and vibrato rate & vibrato depth.

Spectral tilt (or voice brightness) is controlled by the height you are touching the keys.

The overall aim of the user interface is to make it simple to control the many parameters in a live setting. The colours are based on the Solarized theme by Ethan Schoonover.
