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

But comming from Windows/ ASIO it's not that easy 😉
The principles are identical, also the device capabilities. ASIO/wasapi exclusive is just as unforgiving as alsa hw:X - you have to use only stream parameters supported by the device/driver.

If you tried running the loopback CDSP on windows with wasapi exclusive or asio, you would be hitting the very same issues as in linux.

Question: the device can handle lots of in's and out's but to see al of the unused channels in the plot, dis not very comfortable.

Is there a way to show only channels used in the mixer?

I got a question about high-Q IIR, specifically for BM. I am using CamillaDSP 3.0.1 on a Mac mini M1 and 2 Okto dac8pro's. One of the dac8pro is handling the subwoofer output, and the BM is running on one of the CamillDSP instance before Dirac Standalone Processor.
After playing something, but not always, I hear a low-level sound like soft tapping or bubbling from my SVS SB13 Ultra. So far with the testing, it never happened before the BM on Camilla running. After it started happening, it almost never goes away(only once so far). Killing and restarting CamillaDSP never helped yet. Even turning off/on the dac8pro with the front UI(not power cycle), the sound went away then come back with the unit back on. This is very confusing.
The S/W suspect in my mind is the very high-Q IIR LPF for BM. It's around 40~100Hz @ 96kHz Fs. But DP computation in theory should clear out the 32-bit output going to the DAC...

Anyone care to suggest a theory or test method?

I see what you mean and agree... but in most cases you don't need to adjust for eg. count of in- and outputs... its handled by the driver. so i never get in touch by the need to configure this hardware wise 😉
Choosing the right interface normaly result in the fact, that the software already knows these parameters by itself.

What i am wondering now is, that with this hw without plug i can use only fs up to 48kHz, what is correct by using all channels on ADAT... but SPDIF is supporting more on this device... but that's something i can live with 😉
 
How high Q? And what is BM short for?
If you can hear the noise then it's at a fairly high level, far above any normal noise floor. Do you see anything on the camilladsp input and output level meters?
Don't recall the formula at the time... It's 40Hz Fc LR4 LPF @ 96kHz Fs. I meant bass management with BM.

I don't know how to check I/O level meters(used only with text interface), but will find out and report tonight.
