Neural Amp Modeler (NAM) in HISE

@Christoph-Hart said in Neural Amp Modeler (NAM) in HISE:

Haha wasn't all that drama about it being 8x slower than the NAM plugin?

I have no idea, I'm only now touching it for the first time.

I ran direct comparisons in Reaper and a Waveform Synth with NAM on stereo channels consumes 1% of CPU (20% of RT CPU), while two NAM plugins in total consume 0.9% of CPU and 18% of RT CPU.

So HISE is about 10% less efficient, which is good enough and entirely shippable if you ask me.

@Christoph-Hart said in Neural Amp Modeler (NAM) in HISE:

Can't you just embed the JSON content of the NAM file into a script and it will be embedded in the plugin?

I sure can. I feel silly now. Thank you.

@aaronventure

I'm seeing about 25% here with this. Not sure I understood about the multi container thing.

[aaronventure]

@Orvillain you can still see the two cables going into it. You multi node should contain a neural node and an empty chain node.

How well does this nam implementation handle different sample rates? I know some get tripped up if you try to run a sample rate that's different than what your model was trained on.

Strange....
I'm getting a "function not found" error when calling loadNAMModel

I think it was the AidaX, not NAM: https://forum.hise.audio/topic/11326/8-times-more-cpu-consumption-on-aida-x-neural-models

@aaronventure So, apart from AidaX, NAM performance is close to its own plugin, right? Great news then.

Have you ever tried embedding NAM content as JSON like @Christoph-Hart adviced?

As you mentioned above, I can open them externally, but embed doesn't work here.

@JulesV i haven't gotten around to actually implementing this, but it should work, instead of just reading the file as object, i would just paste the data in there

This is the nam file (to upload here, I changed the extension to .txt, but you need to change it to .nam after downloading): A73.txt

Using this externally works. But for JSON, Hise cannot load this complex data, which has a lot of weights, and it hangs then crashes.

@JulesV Don't know if this helps but I have this working fine in my current project:

//ML Model Loader
const neuralNetwork = Engine.createNeuralNetwork("Plasma");

const namModel = FileSystem.getFolder(FileSystem.AudioFiles).getChildFile("Plasma.json").loadAsObject();

neuralNetwork.loadNAMModel(namModel);
;

I renamed my NAM model to a JSON, in this case Plasma.json and put it in AudioFiles as I found Samples wasn't working reliably for me.
This then pops up in the Neural node in scriptnode no problem. This is a 1000 Epoch NAM model so the json is pretty big/has a lots of weights.
Again, hope this helps!
And thanks so much @aaronventure for the help getting this going, it's been a bit of a game changer for me distortion wise!

EDIT: Ignore the Const Var at the end there, copied by accident, doing a few things at once.

this is funny because you could've used the edit to remove it

@aaronventure it's been a long week :
