JSFX Delay and Reverb Time Calculator (Windows-G)

[Windows]

After digging through the Reaper forum and checking out some JSFX utilities that do similar things, I’ve completely revamped my Delay and Reverb Time Calculator!

Now it’s a powerhouse: it takes your project tempo and automatically converts musical note values into seconds, milliseconds, and even hertz. Perfect for syncing your delay and chorus effects to the beat. Switch between automatic BPM detection or enter a custom BPM. But here’s the best part (and my personal favorite): it also calculates predelay and decay times for dialing in your reverb settings like a pro. You can also pick from a variety of pre-delay notes for custom reverb pre-delay calculation.

So, here it is—the ultimate, all-in-one JSFX Delay and Reverb Time Calculator. Ready to take your mixes to the next level! 💪✨

an you screenshot your FX so we can see how it handles BPM ?

What would be nice is if we could choose pre-delay time in ms or beat division.


Note: There has been other scripts about this, like Breeder BPM utility and Tompad MusicMaths, but contrary to Polarity Audio tool, they dont take into account predelay.

I have attached an image now. Once you load it, it automatically gets the bpm from host, a change in bpm gets immediately detected by the plugin and it updates its calculated values immediately.

I'm not sure what you mean by your last statement of being able to choose? It's an automatic calculator that displays its values in seconds and milliseconds.

Oh but your script doesnt display predelay, so it is not relevant. I though it would be like this.

For reference, breeder take on this is based on sliders, so value can be copy pasted


layout is less readable though due to lack of columns in JSFX sliders

Yes, I have rewritten the whole thing. Now, its exactly as you wanted. The only path I am not be willing to thread is the "sliders path". So you have to take note of the printed values on the gui and then type them manually in your plugin, but the interface is very intuitive like the website you linked. Thanks for the suggestion.

Works great. Thanks, this tool is pretty awesome. I already changed all my templates and deleted some old delay & reverb time calculating fx. Really nice.

Wow, nice. Thank you for the feedback, I'm glad that you like it.

[future-bit]

Thank you!

I use The Delay Time Calculator (DTC), so I would suggest making it more compact. For example, make a menu for selecting sec, ms and Hz. And also add a manual mode (it is convenient for calculating LFO).

[X-Raym]

IMHO what it miss most is pre-delay time adjudtability,
cause in fact there are twi ways two choose a predelay time : sound realism (depending on type if space, like this plugin show) and sound clarity, just considering attacks of the source sound (this need to be adjusted panually based on the source). In this second case, we can either use a value in ms or in beat division. But it both case, being able to input / choose this pre-delay value for reverb is what is missing.


@future-bit
I like the compact view of liqube plugin ! Less colums is good to see the related beat division (first column) of each row cell.

I'm working on adding the manual mode, how is it convenient for calculating LFO?

Finally understood after in depth research. Work done. Check link again. Thanks.

I guess he's referring to something like this script



Not a pro but if it's a POV calculation then if the space increases so does the reverb but also the predelay since the distance get's longer too is what i'd imagine

Ok, What about if you move only the predelay slider what happens in the others. I want to see if you don't mind?

if I move any of the rest of the sliders they go back to the previous number since they're tied to the BPM, only the BPM slider can move the rest.

It's a free script, if you have reapack you should have it also iirc

Alright, thank you very much.

[Windows]

I'm making progress taking into consideration all of your suggestions. 85% done. However, do you think it's necessary for me to include different time signature modes for it. I feel like 4/4 is kind of standard so I want to just leave it alone. But what are your thoughts about that?

[gogi]

Very useful tool, I need to install it. Thank you!

Yes it is, you are welcome.

Finally, I'm done with it. I have implemented all of your suggestions.

Changelog:
1. Compact GUI – The interface is now smaller and sleeker compared to the previous bulky version
2. Manual BPM Mode – Switch between automatic BPM detection or enter a custom BPM
3. New Menu to choose between seconds, milliseconds, or Hertz
4 .Manual Pre-Delay Selection – Choose your own reverb pre-delay notes for more control.

I spent time on this. Not an easy task at all. Currently, I don't even think there is any jsfx out there on stash that does all of these stuff in one plugin. I have updated the link in the first post.

Thank you all for your suggestions.

Thx for this!


If you want to push it a bit further, you can hide sliders based on other sliders value (like hidding manual BPM slider if BPM mode isn't set to manual), the function for that is just slidershow( slider_id, hide ) , hide being 0 to hide and 1 to show if I remember correctly


Also, you can associate a named variable to a slider


so rather can calling slider4, when declared as slider2:120<2,960,1>Manual BPM


you can return its value as manual_bpm, if declared as slider2:manual_bpm=:120<2,960,1>Manual BPM

This can help clean the code a bit

Yeah, I have done that now, I used the slidershow @sliders. Now, the manual BPM slider shows or hides based on the BPM mode. The same for the manual predelay note selector. Link updated. Thanks.

I think there is still room for improvement.

1. By default the font is quite large and tables are broken:



2. Make the same design for both tables:

No, that's not the default font I used. Did you touch the code? I considered the visually impaired in choosing my font and its size, as it's something I'm really concerned about. If you have changed the default font then you will have to do all kinds of code adjustments to make it look right.
However, if you accidentally changed the font, then delete this one you have and go back to the link and download the original again. The table is perfect in the original.

No, I didn't edit the code. I downloaded the new version now. That's the big font I see.

It's working fine here. Once you open the plugin:
1. Click on "Edit" on the top right. When the code opens
2. Scroll down to the part I have titled "TITLE---------"
3. Look for the highlighted word in the screenshot I have attched and tell me what font name you have there or screenshot it for me.

Also, are you using MacOS, my default font for the plugin is "Bahnschrift SemiBold Condensed" as indicated in the screenshot. But I'm not sure if it's on MacOS. You do the above steps and let me know.

I have Windows 10 Home.
Yes, the reason is the font: Bahnschrift SemiBold Condensed.
Bahnschrift SemiBold Condensed is missing from my system, and also the size 22 is too big.

If I change the code:

  gfx_setfont(1, "Bahnschrift SemiBold Condensed", 16, 1); // Plugin Name Font  (1-multiplier, font name, font size,...)

it will be better:



Another suggestion is to make it possible to copy the value (not manually type it later).

I have to choose a cross platform compatible font for all OS and then upload a new version.

With regards to being able to copy the values, it is only possible in the JS language through using sliders. I chose not to go in the sliders direction because it will make the whole gui cluttered and I can't draw tables and customize it the way I have. It will be unintuitive. So it's a limitation of the language and I chose readability over using plenty unintuitive sliders. So looking and typing the value manually in ur plugin is currently the only way available AFAIK.
