Spring reverb

[Basslint]

Hello,

are there any libre spring reverb plugins based on simulation rather than IRs (impulse responses)? I know it must be hard to get right (pinging our physics expert @CrocoDuck for some insight) but I find it interesting that all these years, I never came across a single free implementation of it, while proprietary plugins such as Twangström exist and seem to work well. For students getting a physics degree, it would make an interesting final project or thesis, I think!

Perhaps they could be implemented in taopm or a similar system?

PS: Happy Easter

A while back I was trying to learn about how to implement a spring reverb. I found this discussion which seemed like it would be helpful, but I still haven't worked up the gumption to actually try it:

Maybe we could put some minds together here and see what we could do about making a libre spring reverb plugin.

Thanks for the link! I am not any good at physics, but if there some way I can help, I am up for it

The last paper linked (https://asp-eurasipjournals.springerope ... 011/646134) seems actually very interesting.

Hey there! I am very late to the party, but here my few cents.

I am not aware of any open source physical-model-based spring reverb. This is something I wanted to look into, and maybe I will do. For the time being I have only being reading about a finite difference scheme in this book (it has an entire section dedicated to helical springs): https://onlinelibrary.wiley.com/doi/boo ... 0470749012

This paper is a summary of that section, by the same author: http://www.ness-music.eu/wp-content/upl ... dafx13.pdf

Cheers!

Thanks for the link CrocoDuck! Sadly, my physics skills are below secondo superiore level, but as someone who loves surf music, I really hope one day you go ahead and implement it!

For what it's worth, I did a surf rock tune recently and found that Dragonfly Plate did a solid job on the guitar. It fooled my collaborator into thinking I had used a spring reverb.

YMMV, of course.

I think Spring Reverb also can be simulated using FEM - https://en.wikipedia.org/wiki/Finite_element_method
But that requires some simulator to be implemented like I've done with Room Builder plugin.

Hi Milo, would you give a link to that sound file? I'd be interested to hear that sound.

And what settings did you use in Dragonfly Plate?

Thanks!

Yeah, here it is: https://sanderson.band/albums/pity-party/. It is the second song on the album, called "The Beach is Closed." It is more Beach Boys than Dick Dale, so it might not be quite what you're looking for. It's wet, but not dripping wet, if you know what I mean. But I have more surf rock projects on the horizon, and I plan to keep using Dragonfly Plate for them.

Here is a screenshot of the plugin GUI for that track:

Thanks. Yeah, the guitar is not very exposed or really featured as a lead/solo part but I get an idea. What I can hear sounds promising enough to follow that route.

Good luck!

Good track, and it's a fair effort, but not really convincing I'm afraid.

Yeah baby, talking about "dripping"...

I am a big fan of lush spring reverb (my main amp is a Fender Vibrolux) but that is a bit much.

Both beautiful tracks! A personal favorite of mine is Stevie Ray Vaughan & Dick Dale's rendition of Pipeline. Can't say I prefer it to the original because the original was so influential but love everything about that cover, it's really the textbook example of 80s surf rock.
