# pvscross

pvscross -- Performs cross-synthesis between two source fsigs.

## Description

Performs cross-synthesis between two source fsigs.

## Syntax

fsig pvscross fsrc, fdest, kamp1, kamp2

## Performance

The operation of this opcode is identical to that of pvcross (q.v.), except in using fsigs rather than analysis files, and the absence of spectral envelope preservation. The amplitudes from fsrc are applied to fdest, using scale factors kamp1 and kamp2 respectively. kamp1 and kamp2 must not exceed the range 0 to 1.

With this opcode, cross-synthesis can be performed on real-time audio input, by using pvsanal to generate fsrc and fdest. These must have the same format.

## Examples

    kcross  linseg    0,p3/3,0,p3/3,1,p3/3,1 ; progressive cross-synthesis
    fcross  pvscross  fsig1,fsig2,1-kcross,kcross
    across  pvsynth   fcross

November 2003. Thanks to Kanata Motohashi, fixed the link to the pvcross opcode.
