(Unwanted) ScriptNode Distortion
-
I'm sure this is me not doing something(s) correctly, and I'm wondering if someone can help here.
It's a simple (compiled) stereo-to-mono mixer, taken from one of the examples. Polyphonic.
I put a gain stage at the end in case I was clipping, but the signal meters seem to indicate I'm not.
I tried various mixing algorithms, though RMS is the one I'd like.Any ideas? Thanks.

@clevername27 Can you post a snippet?
-
@aaronventure Thank you for your offer - I'm cooking up the simplest example I can - is taking a bit.

@aaronventure Thanks again for your offer. Here are my ScriptNode patches. The two issues I'm experiencing (when any are enabled):
- Significant, audible distortion. With my ScriptNodes disabled, the audio of my plugin is fine—it completely phase-cancels the original audio (when inverted).
- Inconsistent, frequent audible artefacts. It sounds like specific audio buffers are not being filled on time.
My ScriptNodes, themselves, are simple and avoid complex processes (e.g., convolution.)
The plugin itself is largely just a Sampler component with periodic-interface stuff in the deferred thread. (Without ScriptNodes, no amount of plugin instances seem to move the DAW's processor usage indicator.)
I am obviously am doing something(s) very, very wrong here. 🫠

I lay my code-level hat at your feet.

@clevername27 can you create a snippet where you have these networks set up in a mock context that you want to use them in?
E.g. as FX on the master, or for instruments (use waveform synth as a default).
-
@aaronventure I will try—the plugin is 15,000 lines of code, and I'd still need to process the data into its current form when it enters the ScriptNodes. I'll work on it. Thank you.
