Help me understand "grain delay"
Hi,
1st thing I want to know :
When I assign "grain delay" parameters to rack macros, could you please suggest alternative names for the parameters?
What is the closest correct term for this parameters?
2 thing I want to know is how spatialization is distributed inside the plugin, is every other grain just panned hard, or is it more going on?
3 what is the frequency parameter
4 what is the correlation between the frequency parameter and the spray parameter, and what is the correlation between the frequency parameter and the pitch parameter. I guess there is some clever stuff going on.
Cheers

The Spray control adds random delay time changes. Low values smear the signal across
time, which adds noisiness to the sound. High Spray values completely break down the
structure of the source signal, introducing varying degrees of rhythmic chaos. This is the
recommended setting for anarchists.
The Random Pitch control adds random variations to each grain’s pitch. Low values create
a sort of mutant chorusing effect, while high values can make the original source pitch
completely unintelligible. This parameter can interact with the main Pitch control, thus
allowing degrees of stability and instability in a sound’s pitch structure.
The size and duration of each grain is a function of the Frequency parameter. The sound of
Pitch and Spray depends very much on this parameter.

Well, since you asked "What is the frequency parameter?" I figured you hadn't read the part of the manual that describes what the frequency parameter is - it controls grain size. Spray adds randomness to the delay time. I think of Spray as working in the same way as Flux in Texture warping, and Frequency the same as Grain Size in Texture. So Frequency affects Pitch in that it controls the size of the grains that are pitch-shifted by the Pitch parameter.
As for grain panning, I have no idea. I had never thought the grains were being panned, but maybe so.
I'm just kidding about the sassiness....I hope you can take a joke.

Hey man, sorry! Was in urgent need for a tripple espresso or something, again sorry.
Since the parameter is called frequency, I thought it maybe was something with controlling grain rate, which in turn maybe controlled grain length.
I think in some programs with a set density/amount of voces the bigger rate will mean a smaller grain size.

one single grain frequency oscillator drives for grains: two overlapping ones per audio channel. left and right channel are 90 degrees out of phase. at the beginning of each grain, pitch, random pitch and spray (position) is applied. there is no parameter for grain density. there is no panning going on, it just appears to be like this due to the 90 degrees out of phase realtionship between the left and right grains.
Grain Delay is a quite old effect, i think it was already included in Live 1. i always wanted to write a new version of it, with more features. maybe some day....

lol
is that like industry rule #4080?
