Variable-length index list into buffer (w peek~ /poke~) with interpolation ?
Hi, I'm looking for a specific way to put data from an itable or multislider into a buffer.
The list from itable could look like
0 0.0173 1 0.1633 2 0.2395 3 ...
and has a variable index length.
This data should be put into a audio-rate-resolution buffer (with peek~ or poke~ ?),
but the data has to be interpolated across the new resolution and preferably the interpolation function is variable.
So possibly, lots of interpolated values are generated based on just a few input values.
So the point is to create a custom buffer, using XY-pad input that has a variable amount of X-values.
if you know table length, set buffer size using samples
if you know table length, set buffer size using samples(Now edited the question) I should have specified: the buffer size should be fixed at audio rate, which is a much higher resolution than the input data, therefore the question about interpolation.
Anyone know a technique or formula for that? Preferably with a variable interpolation function and variable input index length.
you can of course create a signal and record it into buffer in real time,
for example :
if you want non real time option, try sliding at sample count using line, peek~ etc
Hey, thanks for suggesting the use of function, here's the result.
I arrived at one last confusion: how to eliminate clicks using line~.
Because I'm using cycle~ as a flexible window tool, the audio of course clicks whenever I change the window buffer.
I thought I had seen line~ used somewhere, where's it's always interpolating a signal, in order to eliminate clicks. Maybe I dreamt it.
Please see the patch, I think it's clear what I'm trying to do? But it's not working.
You will get unpleasant volume changes no matter if abrupt control signal values
get caused by waveform change, or waveform itself has abrupt changes.
you can for example update cycle~ only when phasor~ restarts ramp,
and only when waveform changes.
But something like this :
will still produce hickups.
One option would be to insert rampsmooth~ after cycle~
