Description

Distribute an audio signal across two channels with a choice of methods.

Syntax

a1, a2 pan2 asig, xp [, imode]

Initialization

imode (optional) -- mode of the stereo positioning algorithm. 0 signifies equal power (harmonic) panning, 1 means the square root method, 2 means simple linear and 3 means an alternative equal-power pan (based on an UDO). The default value is 0.

Performance

pan2 takes an input signal asig and distributes it across two outputs (essentially stereo speakers) according to the control xp which can be k- or a-rate. A zero value for xp indicates hard left, and a 1 is hard right.

Example

Here is an example of the pan2 opcodes. Play pan2.csd
