Best resource for learning HISE?

@andrewz94 Yes you can make one UI component (knob) control several module parameters (FX), but you will have to script this. I am sure @d-healey has many videos on this topic:

https://www.youtube.com/watch?v=1rs0w4MDNA0

Faust is its own independent programming environment for digital signal processing, with a really extensive library which you can run inside HISE. It is great for expanding the amount of processing you can do within HISE.

https://faust.grame.fr/

If you are interested in FX then Scriptnode is your best friend. If you are familiar with MAX MSP it is similar in the sense that it is node based. There area few examples spread out in the HISE docs, on the forum and in the Snippet Browser on how to work with it

https://docs.hise.dev/scriptnode/101/dsp_network.html

However, taking all this on from the start is not a great idea. The best recommendation is to start with David's Youtube videos and get familiar with the HISE environment, then working your way up from there.

@DabDab

Great okay, I'll have some out next week.
any specific kind of effects?

Some tempo syncd 1/3, 1/4, ..... etc SideChain Effects Like LFO tools or KickStart

Good Chorus Plugins Kind of TAL Chorus plugin

Analogue Emulated Plugin ( if possible) Flanger, Reverb, Delay etc...

How can I implement dsp codes from Musicdsp.org

griffinboy

@DabDab

Implementing dsp from Musicdsp.org is very simple, those are all good basic implementations. It would make sense to show how to implement these.

Analog emulation is one of the hardest and most scientific areas of dsp, I intend to tackle it but perhaps not first.

I'll make sure to cover tempo sync and LFOs
Honestly most of the work in LFO Tool / Kickstart, is writing the system to store and read the Envelope shapes. They often use splines.

DabDab

@griffinboy Thank you so much. MusicDSP.org basic effects implementation is a good starting point. A step by step detail Tutorials.
Later Tempo Sync Lfo tools kinda effects and Analogue fx will be good ( if poosible in future)

Till then I need lots of tutorials from you. It will be a best resources for HISE besides Mr @d-healey .

Once I thought about making FAUST Tutorials for HISE . This is listed in my to do list.

Take care and all the very best.

@DabDab

Thank you, I'm working on the videos but I keep re-working them! It's taking some time because I really want them to hold up well in the future.
I'll be going into a fair amount of dsp theory, as well as a bit of C++ stuff.
The tutorial is kind of directed at my past self.

The only reason I got so deep into dsp, and so quickly is that I got picked up for a very difficult piece of analog modelling and promised I could deliver, so I had to learn c++ , electronics, circuit simulation and juce in a month!

A Faust tutorial would be interesting, I've never used it before. I was tempted near the start but ended up choosing c++ instead.

@griffinboy Like when an actor gets a gig and says "yes of course I can ride horses..."

@d-healey

Sometimes you have to learn on the job : )

DabDab

@griffinboy No problems. If you wanna have good meal from a good restaurant you have to wait for sometime. :beaming_face_with_smiling_eyes:

Yup, Electronics and Circuit simulations specially Analogue one is quite challenging. I am from Electronics Eng. back ground so I know. But I never integrated it into C++ and Emulated.

griffinboy

@DabDab

Ah perhaps you can help me!
My understanding of circuits is poor, I only just get by!

Analog modelling is tricky indeed, most plugins only go a third of the way there, hence there are quite a lot of 'poor' models on the market which fall apart as soon as you compare them to their analog inspirations.

If you're interested in this area we can discuss, but a tutorial that goes deep into this topic will not be out for quite a long time: I am still working on it myself! There is an absurd amount of math and physics involved.

That is my issue. It dares me. :downcast_face_with_sweat:

griffinboy

@DabDab

If you want to start, look at analog modelling papers online. Anything released from DaFX is reputable, some papers are better than others. Look for the newest papers on the subject.

I recommend feeding PDFs of the research into chat gpt and asking it to first summarize the paper, and then in the next method ask it to describe exactly how one would follow the paper to achieve the result, listing off all the steps and relevant math.
This is a good place to get started, to just understand how the techniques work and educate yourself. Using AI as a tutor.

But watch out for academic fluff papers. There are some that waste your time and are really long winded and are just written for word count.
The best papers are ones that link to open source code...

I'll have my Hise C++ Node tutorials out in roughly a week. I'm creating a few that I will release all at once, and delete my old video.

DaFX

Good Idea.

How can I convert schematic to C++ Audio DSP ? This is a schematic of Echo Circuit (Simple Stereo Echo)

Dan Korneff

@DabDab you'd have to have a solid understanding of curcuit design and analog modeling techniques to recreate the schematic. Modeling the PT2399 itself is not a trivial task.
Some of my models take months to calculate.

griffinboy

@DabDab

*edited.

Was incorrect in my advice for this digital delay circuit, see messages below.

ustk

@DabDab The essence of this circuit is not the components around it, which are probably just doing some light bandwidth filtering, impedance adaptations...

The main contribution to the sound being the 2399, the approach would better be a black box modeling of the beast imho

griffinboy

@ustk

Ah yes, I was not exaggerating when I say I don't know electronics
That black box in the middle is an entire circuit itself I'm gathering?
I was confused for a moment, because I use these, and I was pretty sure they are digital.

All of my modelling is transistor and tube based, I've never simulated anything modern.

Yeah honestly I would black box this. If he messages me I'll set him on the right path.
Creating a setup to extract data from the actual chip, and then recreating the ADC, DAC, Amp, Filtering and buffers, digitally would be the strategy here.

ustk

@griffinboy yeah this is a path I'd like to learn too, but the progression curve is... well you get it
The thing is that I am fully equipped with all the electronic hardware one would need for this (except spectrometer but it can be done in a computer anyway). I have never tried black box modeling, and even if it wouldn't be that hard to measure a circuit, what to do with the results it something else

As for Wave Digital Filters, as soon as you get a loop, things are becoming insane. And I don't know any electronic circuits without a loop, most often non linear… I tried with a very simple design and wasn't able to implement it successfully in Faust. Though I computed the loop, there's a CLI helper tool for this, cannot remember from the top of my head so I'll find it once I'm back at the computer

Dan Korneff

If you have limited circuit knowledge, this might be a better solution:
https://hackaudio.com/point-to-point-modeling
As far as I can see, it has the flexibility of WDF, but removes the need for iterative solvers when working with non-linear circuits.

DabDab

@Dan-Korneff said in Best resource for learning HISE?:

Yes, I can do circuit design via Electronics components but I am not good in White Box and Black Box Modelling . I saw many JUCE Analogue emulation videos. Tried Mat lab, Circuit Sim, Octave etc. But no luck.

Dan Korneff

@DabDab If you use WDF or Point to Point, the library and code is integrated into JUCE.
My process is probably similar to @griffinboy. Use ohms law and various transforms to linearize the circuit. Create symbolic transfer functions that represent the circuit. Spend hours upon hours in Matlab proving and tweaking the formulas. After that, it's pretty much just copy/paste the code into a 3rd party node.
You'll end up with a while library of books on the subject, but this is a good one to start with:
