pvsmix

pvsmix — Mix 'seamlessly' two pv signals.

Description

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] 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.

Example 865. Example of the pvsmix opcode.
