Ah, thank you for pointing that out. So if I wanted to use the title I have, I should write an article with that title. But even then it seems I wasn't in line with the quality of posts expected for this site. Will definitely keep that in mind for future posts.

I'm a mod here and have changed the title to one that fits the guidelines better. Don't worry—as others have said, it's a great post! I hope you'll continue to share your work on HN and maybe participate in other discussions you find interesting.

(For those who are curious, the submitted title was "Free guitar plugin on GitHub sounds like $600 tube amp by using deep learning".)

Absolutely it's clickbait, I'm trying to get some visibility on my open source project. To answer the question of why it's $600 specifically, it's based on a model of a Fender Blues Jr. Tweed, msrp $600. The models are evaluated to have a 1.5% error to signal ratio, meaning it's 1.5% different from the actual recorded signal, coming from an SM57 microphone. I really do appreciate the constructive criticism, and well…

I'd say don't even argue about marketing/ads/clickbait with the HN and Reddit crowds. Just ignore that part, trust me, it opens up debates that go literally nowhere and leave you feeling worthless or worse. Any advertising is the devil incarnate to some people. The title worked fwiw. Just take the criticism related to the product itself. Which, to me, looks very interesting, but I'm not into audio at all. So my dumb…

It is a plugin that you play a guitar through live, like an amp on your computer. The tone of a real world amp is what's being emulated. More specifically, the distortion quality, which in tube amps is difficult to replicate with traditional mathematical models.

Thanks!

For people who don’t play guitar, this is really commonplace technology now. Engineers worked out how to model the circuit behavior of any amp a while ago. Powerful valve guitar amps have really interesting effects on the waveform particularly when driven hard, but that valve technology is expensive, unreliable, bulky, and very loud when producing some of the most sought after tones.

The most popular guitar amps now are all solid state, but the internal computer digitizes the guitar signal, then processes it in the digital domain, doing eq, applying the “sound model” of an old amp of your choice, also applying effects like chorus and reverb at the same time. Then the D to A convertor feeds the resulting signal to a neutral transistor power amp circuit to the speaker, at as low a volume level as you want.

The BOSS Katana range or the Fender Mustang GT range are both very popular. They are good value, sound great, and can sound like anything from a Fender Twin Reverb to a Marshall stack set to 11. All without shattering your neighbor’s windows.

Just tried it out, I don't know if I would say it sounds like a $600 tube amp especially in high gain scenarios (it really didn't like my active pickups), for a free plugin it is definitely great. In comparison to the Archetype Nolly plugin from Neural DSP it doesn't really compare, but but for something thats free and can be trained at home on custom audio samples its pretty cool.

Thanks for trying it, much appreciated. Love Neural DSP's plugins, they are the best as far as I'm concerned.

Neural DPS's plugins are great. I actually ended up ordering the real version of an amp I tried with a plugin. I never thought I'd say that! But their plugins are realistic enough that I can actually have some confidence that the real thing will be what I'm after.

Ooh so it's like a Software Defined Amplifier, sounds great!

Don’t let any of this discourage you tho. This is a great contribution to the community. This site just has a preference to more technically descriptive titles.

Well I'm an engineer so that shouldn't be too hard, usually people want me to dumb it down!

Considering this project sat for a month with no stars and after this post (and one hour) it jumped to 134 stars, not discouraged at all!

Is latency an issue?

I'm ready for an esp8266 revolution. Arduino is outdated and expensive. Not that my wish will be reality, both academia and the last company I worked for used ardiunos for various tasks(non production). Not sure why, is it entirely the shape of Arduino is standard and can use Arduino based shields?

Funny enough, esp8266 boards is all I can find in my country. Probably because it's cheap and versatile. I need to try it, but can't think of anything to use it for.

Nowadays it's better to directly start using an ESP32, if you want to experiment. It has bidirectional I2S, (for example mic in, apply dsp, then out to speaker), is dual core, which would allow you to do the audio-related stuff on one core, and everything else (like communications) on another core.

If you then see that you don't require all the good things an ESP32 has to offer, maybe because you only want to drive a LED strip via WiFi and read some sensor values, then you can step down and use an ESP8266
