I have now played quite a bit with my installation and I‘m very happy with Moode on the RPi4.
After having moved my loudspeakers quite a lot in the room and measuring the sound with and without the subwoofer (with REW) I have found a final place for them. I let REW calculate filters for CamillaDSP as a first step, and then „interactively“ worked towards a better overall response (including the room peculiarities).
Regarding this I have two questions:
- What is the maximum number of filters that CamillaDSP can process on an RPi4? I currently have 10 filters for each of the two channels, and this produces a load of 2% CPU and 0.1% MEM for CamillaDSP, which is negligible in my opinion. Are there other restrictions that I do not see, that limit it?
- If I switch to the CamillaDSP view it shows on the devices tab a selection input named „samplerate“ with a tool tip „sample rate for processing and output“. This is set to 44100 (I didn’t change anything here). If I use source files with other rates, then the output rate as shown by the DAC is the same as the input material. Does this mean that the samplerate chosen here is ignored (this would be my preferred variant)? Or does it mean that CamillaDSP resamples the source to 44100, then does its transformation, and the result is again resampled to the same rate the original material had?
I‘m also thinking about having an additional DAC for the subwoofer. CamillaDSP could mix into 2 additional channels that could be processed differently from the main speakers then. But could this be done with Moode or with this have to be done behind the back of Moode?
And again, thanks a lot for Moode, it has made life a lot more pleasant.
Cheers, Joachim
