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.
I'm sorry if I come back to this topic again, I am a newbie but I am interested in implementing the room acoustic measurements and correction function in my audio system. My audio system consists of a pure digital music server coaxially (listening generally 192/24 digital music) connected to an integral amplifier that has its own internal DAC. I was thinking of putting a device consisting of Raspberry PI + HiFi Digi + I / O + DSP ADD ON Board, between the music server and the amplifier. Do you think it can work or, as you have already explained to the previous user, does the DSP card always need the DAC card? In case do you have a suggestion for a device that allows me to add room acoustic measurements and correction to my sound system. Thanks in advance for your response and support
The Digi+ I/O does not support the DSP module. I'm sorry, but we don't offer any board that would fit into your requirements.
Ugo, you might consider DAC+ DSP, it should work with dacdsp-12 profile. It has optical TosLink input and output. If you need to convert it to coaxial, you can use one of cheap converters from Amazon. Or maybe you can use TosLink connections in your system, instead of coax?
