    kamp, kfr pvsbin fsig, kbin

## Performance

kamp -- bin amplitude

kfr -- bin frequency

fsig -- an input pv stream

kbin -- bin number

## Examples

Here is an example of the pvsbin opcode. It uses the file pvsbin.csd. This example uses realtime input, but you can also use it for soundfile input.
