Applying delays on sends

Hi there everyone!

Lately I’ve been pretty much full time on music production, for clients and for myself. And thus I’ve also been doing a lot of mixing.
A big part of my mixing workflow is working with reverbs. I like to dial in a good reverb, or use a very nice IR, then send a lot of elements to it. I tend to duplicate the reverb bus so I can have copies of the same reverb with varying amounts of pre-delay. It’s nice, but it’s a little heavy handed on the CPU (with convolvers it’s not that bad), and very time consuming to setup. I’m looking for solutions.

Is there any way to add delay to a send in Ardour? Any script that could help me with that?

If not, no worries, it’s an incredibly case-specific thing, and I’ll get by making some session templates or something.

Thanks for your answers and happy sound ventures to y’all!

The currently possible solution is to use an intermediate bus with a delay-line

e.g.

track A → bus 1 [delay 1] → bus 3 reverb
track B → bus 2 [delay 2] → bus 3 reverb
track C → bus 3 reverb

For the delay, you could use "Allpass Delay line (from swh-lv2), “Micro Delay Line” (from x42 Delayline, Artificial Latency, comes with x42-plugins on most GNU/Linux distros)

Each of the internal (aux) sends does have a delayline for latency compensation, but it is currently not possible to manually override and increase that delay.

Any delay plugin with feedback and dry set at 0, wet full and a fine enough delay time control would work.

One of them is Uhhyou SevenDelay

I mean sure but where would I place it? is there anyway to have the plugin within the send line?

Just like x42’s example wrote above. What do you mean with “to have the plugin within the send line”?

No.

You place it it on a bus. In the example above, bus1, and bus 2 would just be a bus with delays.

Apologies. I missed x42’s comment, I saw only one notification and didn’t think of scrolling up

Oh actually that’s an alright solution. I’m gonna give it a try, thanks!

Indeed. you can also use ACE-delay (comes with Ardour) in that case.

If you’re on Linux then Holger created a plugin for this:

I haven’t used it myself. That link is to the Mixbus forum but it would also work in Ardour I expect.
