Hi, for what i saw ... the DSP processing only works over other dac card ... is it so?
In that case, the DSP works only in that sound card specifically? if i have another digital output, an external usb dac by example, then the DSP is worthless?
Thanks.
The DSP processing only works for the DAC+ DSP. You can't use it for e.g. an USB DAC.
Theoretically you could process audio on the DSP, send it back to the Pi and output it somewhere else, but this would require some major programming.
Ok, so i must use the hifiberry card as the audio output exclusively, via the Toslink or analog output.
Two questions more:
- I want to add an usb audio interface like the Motu m2 to process analog sound .. that's possible?
- The Toslink input in the hifiberry card ... can be processed and routed to the same card output?
If this works, i can have my 3 sources (streaming, turntable and cd player) processed with drc.
Thanks.
HiFiBerryOS does not not have support for any 3rd party sound hardware.
Yes, the TOSLInk input is supported
Theoretically a lot of stuff can be done with the right software and programming, but I would only suggest to go this route if you a very experienced Linux admin and programmer.
That means, even other recognized device in the OS cannot be used as audio input?
In HiFiBerryOS, only HiFiBerry sound cards are supported.
Got it, thanks.
