Description

"Filtered distortion to add brilliance to a signal"

Syntax

ares exciter asig, kfreq, kceil, kharmonics, kblend

Initialization

Performance

asig -- input signal

kfreq -- the lower end of the harmonics created.

kceil -- the upper end of the harmonics created.

kharmonics -- amount of harmonics in the range 0.1 - 10.

kblend -- blend between 2nd and 3rd order harmonics in the range -10 - +10.

exciter is a reimplementation of the calf exciter plugin.

Examples

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