Re: [sc-users] DelayL

[Dan Stowell <danstowell@xxxxxxxxx>]

Jitter? No. Why would it cause jitter?

Cubic interpolation is more computationally complex than linear
interpolation, so it'll take more CPU to calculate. But it's a better
interpolation in that it creates less artifacts (although the
difference may not be obvious without doing some detailed listening).

Here's me testing the difference in CPU load by running 250 of each
unit at once:

s.options.memSize = 8192 * 16;
s.boot;
// On my machine, this synth uses about 39% CPU:
x = { var son=PinkNoise.ar; 250.collect{DelayL.ar(son, 0.2,
0.2.rand)}.mean}.play
x.free;
// On my machine, this synth uses about 59% CPU:
x = { var son=PinkNoise.ar; 250.collect{DelayC.ar(son, 0.2,
0.2.rand)}.mean}.play
x.free;
