Detailed Description

Impulse Train Synth

Ruby version: Synths::ImpulseTrain

This produces an impulse train, which corresponds to:

inf
 Σ cos(n*wt)
n=1

If the scale parameter is set, the (bandlimited) amplitude of the wave will be decreased such that the peak is always under 1.0. This is probably not what you want unless you are using a constant frequency value.

Initialize impulse train synth

See cs_synth_destroy

void cs_itrain_set_scale	(	cs_itrain_t *	self,
		int	scale
	)

Set whether to scale the bandlimited waveform to 1 or not. This is probably not what you want unless the frequency is constant. For manual scaling, note that if a given frequency doesn't clip, no frequency above that will clip.

Ruby version: scale=

Parameters:

scale

scale. 0 for not scaling, nonzero for scaling
