Realtime DSP. pc - Macmini + 8x CX31993 + CamillaDsp?

[neifle]

Hi all, is it possible to use an old mac mini as a realtime dsp using Jack or Loopback software to output sound from the computer and process it ? Also, is it possible to transfer sound from pc to macmini via hdmi in order to set up multichannel sound and in camilladsp customize each channel as needed, with its own frequency slices and room correction ?

For the first part, probably, depending on exactly what you want to do. You just need suitable input and output devices. The HDMI part is trickier as the mac mini doesn't have an HDMI input. You could use an HDMI audio extractor, but unless you want to spend a lot they are limited to older multichannel formats like AC3.

I'd like to use a mac mini or any other minipc as a multichannel dsp so I don't have to spend a huge amount of money on pro solutions. I want to output all the sounds to this dsp in realtime from my computer, work, edit video, etc. For what? To connect and customize a custom subwoofer, as well as to build an budget atmos in the future.

You need some way to get your multichannel output from your PC to the mac mini (or other small computer). If you don't already have a pair of audio interfaces with sufficient outputs and inputs then it might be cheaper to get a single board computer with a USB device port like a Raspberry Pi 4 or 5. Once configured it will look like a USB audio device to the PC. You then need an output device with enough channels, either USB or the HifiBerry DAC8 (for Pi 5 only). This thread should cover most of the details.

Budget Atmos will be a problem as AFAIK there is no suitable decoder. A couple of threads with more details:

so much thx for your replies! my monitor is lg c2, is that gonna help for decode atmos?

I doubt it, but check the manual to be sure. Atmos decode is usually done by a soundbar or AVR, not the TV or monitor.
