The best part of these projects is the student interest. The fundamentals here are then well learned and will be retained.

[@nckwntzl]

Very awesome project. We are entering a new age of hardware dsp accessibility with the low cost of fast microprocessors

[@giatomm]

Wonderful! I really appreciate the effort these students put in projects

[@Lantertronics]

Thank you for your kind words!

[@thechrisricci]

Fantastic. I've been interested in digital reverb circuits for a while now. These sound great.

[@aer0fficial]

huge! loved this project. funnily enough, i initially learned about the daisy seed by taking a class with tom erbe. will be checking out this code & messing around with it :) thanks for sharing Aaron and Andrew!

[@sjay4673]

This is an amazing project! Thanks for sharing it, Aaron and Andrew! 👍

[@funkbungus137]

oh wow, this is cool, I had never thought of using allpass/comb filters, I tried making a reverb a few years ago in Max/MSP and just used a bunch of delay lines and could not figure out how to make it "smear" like you said. awesome.

[@Lantertronics]

Highly recommend checking out the Valhalla blog -- so much good info there!

Also check out the Sean Costello "on reverb design" talk on KZbin.

This is awesome! Great work.

Thanks a lot!

Back in the mid 80’s I had a rack mount spring reverb in my guitar rig, best reverb ever, I wish someone could successfully model that one.

[@SynthOSphere]

Sounds amazing! Looking forward to hopefully build this and fiddle with it. Great work! Thanks for sharing!!

[@CornetHornet91]

A very cool project with huge potential! Great demonstration and explanation. Thanks for sharing!

Cool project 😍

Thanks! :)

[@minimod_synths]

Really great work and project! Listen to how Andrew explain his project is a pleasure. I'm an engineer and amatour sound designer who use Moog Mother-32 and Korg NTS-1. I work in PHP but I started to learn C++. Thanks for the link to repo and diagrams! it will be a pleasure to look into and learn more. Was Andrew using VSC for C++ IDE? I try with JetBrains CLion but it's just a tool.

Alfa Mist. A man of culture.

[@L2.Lagrange]

Very interesting. I will have to look into the Daisy Seed. I have been using STM32 for some audio DSP stuff lately. That looks like a cool tool. Edit: The FDN network is also very interesting

[@tinkerwithstuff]

Cool! The furthest I ever got doing a reverb was to implement the stereo reverb diagram (probably woefully outdated) out of Chamberlin's 1980's book, even implementable by me math dummy, but it seemed somewhat usable :D

[@Lantertronics]

Some of those older reverb algorithms have their own charm. :)

[@cheater00]

Wow, that is lovely

[@Lantertronics]

Thanks so much!

[@woosix7735]

I should make this someday

[@Lantertronics]

Check out the GitHub :)

[@stephengunnell5048]

Cool! has Andrew looked at Ron Berry's Acoustic modelling pages?

[@Lantertronics]

Not sure... I will let him know about it and check it out myself.

[@stephengunnell5048]

@@Lantertronics Oh, btw, you need to click on the acoustic modelling menu button without using the drop down menu to get page one which describes the basic module.

[@clausanders2886]

Hve a look at the Teensy 4.1 Board. It lack's of the ADCs (which can be added via daughter, but the power is unbelievable:FP DSP at 600Mhz).

[@euglossine4ever]

Not a proper tool for dsp design, it’s block based processing makes it extremely difficult to work on per sample basis

[@clausanders2886]

@@euglossine4ever The Daisy Seed /Axoloti/Bela etc are all block based. Only 'real' DSPs may able process on sample basis. But what's wrong with block base?

[@Lantertronics]

A few years ago I had a senior design team that used a Teensy for a guitar effect.

[@euglossine4ever]

The teensy audio thread is not accessible in the same way as daisy, juce, bela, and most c++ audio routines are, a good example of this is the big discussion of interpolation on their delay object, you should see the implementation of a tape echo to achieve the effect

[@clausanders2886]

@@euglossine4ever I actually have implemented a tape echo effect with the 4.1 without any problems. Yes, Teensy uses still 16Bit Integer Blocks, but coversion to and from float is no problem. I have even created a complex Synth with 1028 Osc/Env and Filters without any hickups.

[@mavisbavingson2299]

so cool!

[@Lantertronics]

Thanks!

[@AnalogDude_]

Cool, seams this Daisy board has a ram chip.

[@Lantertronics]

Yeah, it's the one with the extended memory.

[@AnalogDude_]

@@Lantertronics I like the Datasheets of Microchip, it's easier to pinpoint what you need, most of the time, via their KZbin channel, i asked them for a Fubarino Max version with DDR ram compatible with the Arduino IDE, great idea make a suggestion via email, than they send you to their website, where some 3rd service company handles the email, Than this guy has no clue with what you discussed with the KZbin "team", makes some other suggestions and in the end you get nothing done. They have a PIC32 "series" that's comes with DDR ram support. it would take months to, understand, hack and adept the Fubarino firmware with the USB stuff. The Arduino IDE is great, just 2 buttons, strictly biznis.

[@funktorsound]

May I ask, what is the book shown at 2:57 describing the delay line parameters?

[@Lantertronics]

Check it out here: ccrma.stanford.edu/~jos/pasp/Artificial_Reverberation.html

[@Lantertronics]

In case KZbin deletes the link, you can find it by google searching: Julius Smith artificial reverb

[@LouieToblerone]

Anyone coding on a Norns?

[@Lantertronics]

I hadn't heard of Norns before -- I just checked it out, it looks very interesting!
