There is some good DSP products out there, especially most recently as big tech companies have investing into it - for example Sony has its 360 Reality audio DSP in the PlayStation 5 which up converts content into 12 virtual channels using a custom Sony design audio processing chip - this system is actually works very well with headphones. There are products out there that do attempt to upmix and create surround sound out of thin air and most are only marginally effective. Unless something has recently changed, no Sonos products support up mixing, Sonos appears to be very anti DSP in its software design.ĭSP is general has its issues and it's not a magic pill.
