pvsmix

Mix 'seamlessly' two pv signals.

This opcode combines the most prominent components of two pvoc streams into a single mixed stream.

Syntax

fsig pvsmix fsigin1, fsigin2

Performance

fsig -- output pv stream

fsigin1 -- input pv stream.

fsigin2 -- input pv stream, which must have same format as fsigin1.

Warning

It is unsafe to use the same f-variable for both input and output of pvs opcodes. Using the same one might lead to undefined behavior on some opcodes. Use a different one on the left and right sides of the opcode.

Examples

Here is an example of the pvsmix opcode. It uses the file pvsmix.csd.
