CamillaDSP - Cross-platform IIR and FIR engine for crossovers, room correction etc

I was hopping to try out the new short cuts in the next30 version. Looks like this requires building the camillagui front end in addition to the changes in the backend. Is the front end build available ? I have no idea how to do this. If not, no problem, will just wait for the release of the 3.0 version.

Thanks, Mr. Enquist.

All IIR filters for an MEH loudspeaker and RYTHMIK subwoofers. Using a many more filters than would be allowed with xilica's fixed processors but not ridiculous.

So six channels - which could turn into eight channels when I get another DAC so the subwoofers will have their own (two per channel).

No fixed filters and at the moment no delays. Not very demanding - it says my "resource usage" is less than 23% Running at 24/96.

The xilica has dante and I am using that with a REDNET box for the XLR connections. This does not have to be. I know I would have to get a dante card for the Camilla machine if I decided to continue with it which I am sure would require x86.

Hope I have not gone on too far. The fact that CAMILLA can do things the xilica cannot do is intriguing. Maybe there is improvement possible with the FIR filters? Do I understand correctly it can run at 24/196?

Seems like an interesting project! If you think it would be anti-climatic I would appreciate your opinion. Always plenty to do with a needy audio system.

Thanks for your time and counsel,

rickmcinnis, with a MEH you will need a low noise DSP.
Two projects to wet your appetite, the first is building a CamillaDSP on a Raspberry Pi and using a Motu Ultralight Mk5 audio interface for balanced outputs and the second is a long pedantic set of posts showing how I tri-amped my K-Horns using a RPi system.
The Klipsch community thinks very highly of the Xilica gear, but they are so expensive in Australia that I looked elsewhere and found the CamillaDSP tutorial and have found that CamillaDSP is so much more capable than the Xilica for Loudspeaker work.

I got a nice improvement in my system when I switched from biquad crossovers to FIR, so yes I would say it's definitely possible.

Yes it can run at 192 kHz, or higher. And it can use 24-bit samples. Internally everything is done with much higher precision (64-bit floats), with conversions at the capture and playback ends.

Hi all

Doing my first steps with camillaDSP on Windows.
I got it running.. but...
I have an old RME FirefaceUC interface. in principle it is working, but only with two channels in the output. the wdm driver seems to make a "New Device" for every new 2 channels.
Is there any chance to get it running?
As you can see in the dvice name, it is adressing channel 7&8 but i can not choose all or something like this.

OK... found it!

First i had to create a 7.1 suround device in the device settings. After that i had 8 channels available in the device tool.

And in addition, I need to deactivate all enhancements in windows sound device settinge... even if there is nothing selected... strange 😉

It's a checkbox in the gui. Look in the lower part of the left panel, under the buttons.

Got it, I had never ticked that option until now.
That Graphic Equalizer can make a middle quality bookshelf speaker sound appalling and back to normal in real time.

I had some trouble in the beginning of my use of the Digiface (opto) - remember? 🙂

On Mac OS it presents everything as from one device. Below pictures is from my computer using 2 toslinks i.e. 4 channels for a 2 way active system.

This ADAT structure is a bit confusing but there is 4 ADAT per Toslink channel so for a normal stereo Toslink, 8 ADAT channels will be presented...

It will of course look different in Win but I would assume its still as one device - checking a manual should reveal how it is... I suppose its available online...

Hi

I have the same interface and try to use it on OSX… I made the same setup config in OSX Audio/Midi Setup, but in CamillaDSP I can not route the input channels. Independent of the Mixerß settings, i always have a 1:1 routing, where channel 1 ist connected to output 1, 2>2, 3>3 and so on.

Any ideas what I am doing wrong?

Check so you don't actually use adat in Totalmix as I assume they will be limited to 24/48 and maybe even downsampled if offer higher.... - have t admit this is a bit of a guess...

MacOS Audio/Midi app will work to setup your channels.

To be honest: i am not sure, if the software side in Totalmix is limited to 24/48... but will check!
But at the moment i am running only 24/48... i think the fact, that we have 64Bit through the complete dsp chain ist the big advantage.

I know... but there is no need at the moment 😉

But i would think, that the ADAT protocol starts at the hardware output. And so it is possible, that everything in Total mix is routet in full samplerate... The fact, that you can mux up to i think four channels, to get higher Samplerates (up to 192kHz) even on ADAT could be another reason.

My Digimix is configured as SPDIF Device in the RME Software... here we can transmit 192kHz without muxing.

But how ever: it works the way i need it, because 48kHz ist fine for me. So lets get back to the wonderful CamillaDSP 😉

I really start to love it 😉

Hi,

I'm having a question regarding the volume range of CamillaDSP.

There are two different devices running CDSP in my house. Both are running on a Pi4 but with different sound devices.
In the GUI I can see the volume is adjustable from -51 to 0 dB for both of them.

The upper limit of 0dB is comprehensible.
Why is the lower limit at -51dB? Does this value depend on something or is it hardcoded in CDSP?
