Real time pitch shifting with ScriptNode

[aaronventure]

@FPSzky use faust

Theres this https://github.com/azur1s/elysiera/blob/main/

And this https://github.com/thedrgreenthumb/faust/blob/master/shimmer.dsp

@aaronventure
If some external codes are embedded in a Faust dsp code, how can we run it in HISE? For example, like this Shimmer;

import ("music.lib");
import("filter.lib");
import("effect.lib");

It doesn't work: https://github.com/thedrgreenthumb/faust/blob/master/shimmer.dsp

@JulesV go look in the repository with your .dsp code,there will be the .lib files but in many cases these libs are now in stdfaust

[JulesV]

@Lindon Thanks for the info.
Do I need to copy the lib files to the Faust folder?

[Lindon]

@JulesV I look at thr code that is being used in the dsp and copy over the relevant functions from the lib file

[JulesV]

@Lindon Sorry, but I can't see the .lib files in that repository.

[ulrik]

@JulesV I found the libs here:
https://github.com/grame-cncm/faust/tree/master-dev/embedded/faust4processing/src/faust-libraries
and they seems to be included in the main Faust lib

@JulesV said in Real time pitch shifting with ScriptNode:

@Lindon Sorry, but I can't see the .lib files in that repository.

yes - as @ulrik suggests your first thing to try is the std lib

[JulesV]

If the .lib files have already been included, then there is something else.

The below Shimmer dsp code is not working for me.

@JulesV try adding the line;

import("stdfaust.lib");

at the start..

@JulesV Try to use online faust editor and let's see if it does the same error or not
