The Orvillain DSP Thread

[Orvillain]

I started one of these before, but then I flounced and deleted it. Like a total arse biscuit. I thought I'd start this again because not everyone will be bothered about checking the RV-5 Analysis thread. So here we go... part 2....

Recently I have been learning about reverb design, because I'm super arsey about delays and reverbs. Anyway, show don't tell.



This is an algorithm I wrote over the last few days.

Other stuff I posted before.

A super basic digital delay, running on embedded hardware (the DaisySeed platform)


And a reverse delay on the same platform:

Arse biscuit or not, this is cool.

This sounds very nice. It has a very pleasant shimmer, but doesn't sound too intrusive or washed out. I like it!

I've just fixed the clicking and lack of smoothing when adjusting the filters.

Now to my understanding, back in the early days of digital pedals, basic one-pole filters were used. But I am curious what it would sound like if I switched the one pole filters for biquads, or even something more characterful like a state variable filter or a Moog style ladder filter; all of which I have code for already. Could be an interesting test!

Hell yeah. Keen to hear more. Have you read the Valhalla DSP blogs about vintage reverb designs? I imagine they would be fun to implement in software.


Also, arse biscuit got me chuckling.

Yeah man! Poured over those a lot! He's got a ton of info here:

So good hey! I studied control systems in 3rd year uni so a lot of the math is familiar but I've done zero coding since. Probably a rabbit hole best avoided for me at this stage

 

[Orvillain]

I got the nuts and bolts of a reverse delay done today.

 

[Richard_G]

Looking forward the hearing more about this.

Ew, QC.

Joking. This is awesome.

Those sound dope dude.

A delay with more modulation types and more granular controls of the modulation in general would be sick. (Like the types of controls on the FAS modulation page) Most delays are fixed, and just let you tweak the amount.

Cheers dude! I've made a lot more progress since then. More vids coming soon.

 

[Orvillain]

Got one of these to analyse!

With this technology, is it possible to make a delay with completely random delay times and repeats? I want to build one and name it after our national train company...

Yes. You could even have it randomly change things every time you turned it on, which I'm sure would really capture the spirit of Greater Anglia trains. Could even have it just randomly stab you for a bit of that London touch.

Those sound great dude. I love threads like this. Could you load algorithms you've written onto FV1 chips? There's some great FV1 projects on the DIY pedal scene but it's not something I've spent much time looking at tbh.

The chip I use for prototyping is DaisySeed. Which is about as powerful as something like a Meris MercuryX, on paper.

FV1 is definitely another option though. Cheaper too!
