S/PDIF input with parametric EQ?

Thanks Tim,

I'll look into the Bitlab article to see what's what.

As for S/PDIF-in HATs, if I'm understanding correctly the key question to ask manufacturers is whether audio switching is done in software? I.e. can the digital signal be fed over the I2S bus to the rPi so as to be manipulated in software before output?

Thanks,

Ian
