the number of output channels
the input signal
the pan position. Channels are evenly spaced over a cyclic period of 2.0.
the output channel position is pos / 2 * numChannels + orient. Thus, assuming an orient
of 0.0, and numChannels being for example 3, a pos of 0*2.0/3 == 0.0 corresponds to the first
output channel, a pos of 1*2.0/3 corresponds to the second output channel,
a pos of 2*2.0/3=4.0/3 corresponds to the third and last output channel, and
a pos of 3*2.0/3=2.0 completes the circle and wraps again to the first channel.
Using a bipolar pan position, such as a sawtooth that ranges from -1 to +1, all channels will be
cyclically panned through.
a control rate level input (linear multiplier).
the width of the panning envelope. The default of 2.0 pans between pairs of adjacent speakers. Width values greater than two will spread the pan over greater numbers of speakers. Width values less than one will leave silent gaps between speakers.
the offset in the output channels regarding a pan position of zero.
Note that ScalaCollider uses a default of zero which means that a pan pos of zero outputs
the signal exactly on the first output channel. This is different in sclang where the default is
0.5 which means that a pan position of zero will output the signal inbetween the first and second
speaker. Accordingly, an orient of 1.0 would result in a channel offset of one, where a
pan position of zero would output the signal exactly on the second output channel, and so forth.

An azimuth-based panorama UGen. It uses vector-based-amplitude panning where the arbitrary number of speakers is supposed to be distributed in a circle with even spacing between them. It uses an equal-power-curve to transition between adjectant speakers. Note the different default value for the
orientargument!Use case: To spread an multi-channel input signal across an output bus with a different number of channels, such that the first input channel is played on the first output channel (no spread to adjectant channels) and the last input channel is played to the last output channel (no spread to adjectant channels), you would create a dedicated
PanAzper input channel where the pan position isinChanIdx * 2f / (inChannels - 1) * (outChannels - 1) / outChannels.
