Vocal Pitch Shifter

VocalShift VS1 is a stereo vocal pitch shifter squeezing two channels of high quality pitch shifting into a single effect. It has a very low latency (<6ms), covers the whole vocal frequency range, and minimises the phasing and flutter artifacts common with many pitch shifters.

VocalShift allows large shifts of up to +/- 1 octave, with a further switchable octave downshift. The wide range makes it ideal for theatrical or more extreme musical effects. The left and right channels are fully independent, allowing separate, high quality pitch shifting on each. These channels can be used in combination with the stereo width control to present each voice separately on the left/right output channels, or both centred on the stereo channel.

The two channels can be linked (right channel settings follow left channel settings), and reset to flat (zero shift) by single button presses.

Semitones - Sets the amount of pitch shift applied to each channel in semitones. The range is -12 (one octave downshift) to +12 (one octave upshift). The current value is displayed in the centre of the rotary. When ‘active’, the control glows yellow/orange. In Link mode, both corresponding rotaries on the left and right channels will be illuminated. A change to either will then be reflected in both.

Cents - Sets the amount of pitch shift in cents (100 cents = 1 semitone). This is added to the setting of the Semitones (and oct down switch) control to give the overall shift (+1 semitone and +50 cents = +150 cents pitchshift). The cents control is useful for providing very small pitch shifts, for example for phasing and doubling effects.

Oct Down Switch - Provides an additional 1 octave downshift to the current pitch shift settings (i.e. +12 semitones and -1 octave = no overall shift).

Flat - Sets all pitch shift controls to zero (Semitones, Cents and Oct Down are all set to zero).

Width - Controls the stereo width of the two pitch shifted voices, and therefore the weighting of each in the left/right output channels. At the “Mono” position, the left and right channels are mixed equally to both left and right channels resulting in a centre pan, mono effect. At the “L/R” position, the left voice is fed only to the left channel and the right voice to the right channel. Other positions graduate between the two.

Link - Forces the left and right voices to be matched. If the two channels have different, non-zero settings the right channel pitch shift settings will be set to match those of the left channel. If the link control is then turned off, the right channel will restore its settings from before the link was turned on. The Link control links the Semitones, Cents and Oct-Down control. Pressing either “Flat” switch when Linked results in both voices being set to zero.
