EVOC20 Brings Vocoding and Formant Filtering to Logic Audio
March 7, 2001
The EVOC 20 package actually contains three new software products. Firstly, the Vocoder with up to 20 bands of filtering and advanced monophonic pitch tracking. Secondly, a Vocoder with a built-in polyphonic carrier sound engine, and thirdly a formant filterbank. All feature an elegant new graphical user interface.
The EVOC 20 architecture was modelled after the finest analog vocoders, and allows the sonic characteristic of the analysis signal to be printed to the synthesis signal. The first unit monophonically tracks the pitch of incoming audio and delivers results which "sing". It is best suited to spoken or sung vocal phrases, but can deliver interesting results on any sonic material, particularly percussion.
The second unit accepts polyphonic MIDI input for control of its polyphonic sound source, and can be played, just like "classic" vocoders. Both units feature high and low knobs to determine the part of the signal to be examined.
On both units, Formant stretch and shift controls encompass a wider frequency range or can shift across it. Resonance controls the "sound" of the vocoder, ranging from soft and purring, through to vicious and snarling. A "freeze" function allows the sonic characteristic of the analysis signal to be captured.
The third unit is a formant filterbank. It features volume faders for each band, allowing levels to be set freely for unusual effects. It also allows control over filter bandwidth and range via the formant stretch and shift controls.
The EVO C 20 runs under any program in the Logic Audio series from Version 4.0 upwards and is copy- protected via CD-ROM.
Pricing and Availability
German recommended retail price of the EVOC 20 is 159,00 Euro.
