Hello !
Thank you for the software !
For your problem about the calc for PEQ, you can maybe ask the guy who make the software "CorrectPlot" : his software can plot the frequency response of different parametric filters for Berhinger equalizers !

Maybe he can give you some info to help you ?
(his e-mail is on his website)
Good luck !

gain[fi]=20*LOG(gain[fc]^(SIN(MIN(fi,fc)/MAX(fi,fc)*(PI()/2))^(PI()/(bw*SQRT(2)))))
hahaha
gain[fi] is actual gain in dB at fi
gain[fc] is factor, i.e. gain of 4 = 12dB at fc
calc gain[fc] using 10^(gain[dB]/20)
fc is centre frequency
fi is incident frequency, i.e. to calc actual gain at 500Hz, fi = 500
bw is bandwidth in octaves, 1/3 oct = 0.3333
can attach spreadsheet if anyone wants it (with pretty graphs)

Hi
Cool can't wait to try!
But i dont understand the function
min(fi,fc)
max(fi,fc)
Further more why al the log conversions?
The frequency scale is already log.
So why not using the pixel offset?
You have to paint it any way.
Or............?
Like i said i'm a mathmatical dissaster.

the min() and max() functions select the lower, or higher of the two numbers contained in the braces, so min(40,75) would return 40
it's just to get it working above and below the centre frequency
the logs are because I changed the gain (dB) into actual gain before doing the function, and then back to dB again for the result
the frequency is entered in an array, and then the function is executed for each 1/60 octave frequency in the array, giving a resultant array to plot the graph
of course, you add each of 10 functions results together for the overall effect at each Fc
spreadsheet is too big to attach, please email if you want one
bed time now...

I'm just trying out this software this evening. It worked first time, I'm very impressed!
An externally hosted image should be here but it was not working when we last tested it.
An update
Hi
Finnaly another release
There is a memory page added.
Here you can download all memory presets.
They provide 2 dropdownlists.
From were you can either
load a memory preset or
preview a a memory preset.
The preview gives you the oppertunity to check the settings before you load them into the Ultracurve.
-some visual adjustments
-kown bug. Presets that are not located on a sequential base (presets after a empty preset) are being wrongly adressed.
Have fun with it!

Re: An update
I realy do have fun with this great application Simon.
I know you are working hard to sort out all kinds of bugs and tech issue .
And I understand that as the programmer you priority is your own wish list.
Today a was trying to compare some minor changes I had done in one of the modules. What I realized was that by the time I had bypassed both left and right channel my ear had already 'tuned' itself to the sonic change from just the one channel.
With this experience in mind it would make sense to make a 'Stereo link' button on the 'BYPASS' tab.
While I'm at it - The 'Stereo Link' on the 'PEQ' tab works great.
But it would be nice to also have a button called something like 'Link Controlls'.
It would work somewhat different than the 'Stereo Link'.
Let's say the controll for Left 500Hz is sett to 0dB and Right
channel to +3dB. When user enable 'Stereo link' both controll are
set to same value when one of the controlls are moved.
But this new 'link' controll would consider the differece between
channels. i.e if user trag 500Hz Left channel from 0 to + 3dB
the Right channel would now read +6dB.
This would make it possible for us to maintanin the diffence
between channels when in 'Dual Mono' mode.

Hi HansR
I think there's a shortcut to the simultanious sliding.
That would even bring things like BW/OCT in motion! I hope
Good thinking!
Consider stereo link at the bypass page as done.
Also switching between menu screens on the screen dump page!
But I'll have to start on it!
Now!

Seoman - quick reply!
Yes I will certainly try running this on Virtual PC. The problem I may have is that I use a G4 (older Mac model) for my music playback and it may not be able to cope with Translating XP. I will definitely try this and let you know though.
The application is such a good idea - I'd love it on my Mac, since all my music is now played back via the computer and to be able to control the DEQ from there as well would be terrific.
Can I ask you as an aside - do you have to attenuate your SPDIF signal into the Behringer to avoid clipping? I do and I am sure I shouldn't have to.

I cant predict is the emulator is smart enough to handle midi.
But who knows.
I don't attentuate any digital signal!
But if have the DEQ gain set to -7dB.
This because of some corrections that increase the input signal.
I'm not sure if clipping on the input is an actual cliped signal.
A 0dB signal is not clipped but there is now way to tell if it's higher or not.
So i guess the clipping indication is set to 0db.
Wich is no clipping at all.
I think you should monitor the output signal and check for clipping.
wich can be corrected with the gain level on the "UTIL" page.

Please, could you post your findings?
My DEQ does the same!And sometimes it give me bleeps and plops when CD ends. Fist I though it was my Pioneer DV-656A player, but have now confirmed that this is not the source.
I aslo hear a terrible sound
in my speakers when I turn on the DEQ when optical is selected as input source. Analog input is fine.regards
