Hi all,

I would like to start a discussion whit everyone who use vst plugin's about how you make your tuning. Maybe we can improve each others.

Exemple, here's my setup in Console:

First, i got 1 Electri-Q equaliser on each channel to make general adjustment, then goes the Frequency Allocator to separate the frequancy over 4 ways (tweeters/mid/mid-bass/sub). On each resulting channel I put another Electri-Q equaliser to make speaker specific adjustment. Then I use VoxengoAudioDelay to setup time delay on each speaker.


Some question I got unanswered:
-The first Electri-Q equaliser i use is in Linear mode and the second is in Maximum phase. This for all speakers. Does it seam okay? Does anyone have more experience whit the Electri-Q modes?

-My crossover are not using the same slope for every speaker. Exemple, my sub is crossed at 70hz 12db/oct and the hi-pass on the mid-bass is lower at 50hz whit a 24db/oct. I assume i cant use Phase Arbitrator on a crossover point like this?

-When using Frequency Arbitor whit a crossover point whit the same slope, I noticed some glitch in the sound while playing sweep. Is it a wrong configuration from myself? I would also like to have your opignon on Phase Arbitrator.

-Does anyone use reverb and have good result ?

....

Here's my current setup:

Console for conencting all plugins
2x 31 band EQ (don't remember which one)
Frequency Allocator (Full)
4x Voxengo Delay

I have only used a little bit of EQing so far. i jsut used it to remove some peaking on the passenger side, but I really need to do more. So I have no answer on your EQ setup at the momment.

I read in the manuals for Allocator/Arbitrator, that it is best to focus on the low pass filters when setting up Arbitrator. I asked almost your exact question over in the Thuneau forums about slopes and gaps with arbitrator but I haven't seen any answer yet.

Also keep in mind that when trying to figure out what slope to use for Arbitrator, you need to use the elctrical slope+acoustic slope of the speaker. Really I just recommend experimenting unless you can measure and know for sure what kinds of slopes you are dealing with in the car.

I thought of another setup that would minimize plugins if you weren't going to use Arbitrator and wanted to use Allocator lite.

Console
2x any EQ
Allocator lite x2, one for left one for right.

By using allocator lite for each side, you can have independant phase inversion, time delay, level adjustment, and 4 band parametric EQ for each channel + whatever EQ you string it together with in Console.
Just some of my thoughts.

What kind of glith are you seeing with sweeps in arbitrator? There will always be some nulls and peaks in a cars frequency response. It's called comb effect or comb filtering.

I'm looking at experimenting with Convolver and Room Correction. Have you considered this at all?

Thats interesting. The glitch i was talking about are some "tic tic" during the sweep. Ill try to figure out when exactly i get this.



I dont really know how to figure out what is the electrical slope or the acoustic slope of my speakers. Ill search about it. If you have any usefull link about it, they are welcome.



Good idea. Ill try whit Allocator full to see if my CPU can handle it.



Really interresting. But the hard part seem to record the car impulse response...
Have you ever tried it?



About Electri-Q, does anyones have some experience with it and the different modes?
Ive tried the Linear IIR (take a lot of cpu) and Linear or Maximum mode. I finaly took the Maximum phase setting... Dont know if it is the best either and if its good to use it even whit the midrange and tweeters...

The "tic tic" is probably a resource issue or latency problem. I have an ever so slight tic tic going on as well, but you really need to listen for it. I think there might have even been a few posts in the thuneau forums about it but I'd have to do some digging to find it. If you go with Allocator lite I think you won;t have that problem, but you don't get arbitrator.



Acoustic slope is where the speaker rolls off naturally on its own. So if you are using a crossover point at the point at which teh speakers frequency plot drops off, then you have to include that slope too.

Ex: midrange rolls off at 200Hz @ 12db/octive and your corssover is set at 200Hz @ 12db, then arbitrator should be set at 200Hz @ 24db.

I have not had enough time to attempt measuring impulse repsonses and do room correction either. That is something I plan on experiementing with this winter. I ahve downloaded a few programs to do this, just haven't had the time.

Sorry I can't help with the EQ for now.

I tried allocator as well, and had horrible ticking...
Probably a latency problem like Durwood said, but generally, I think the plugin is a waste of resources...
