Topic: Question about DSD and processing

I've always wondered with how things can't process DSD audio directly and have to convert it to PCM first, is that something that is mathematically required or simply done for convenience? Is it actually mathematically impossible to do signal processing on a DSD signal, or is it just that we've not bothered to develop the algorithms for it for lack of needing to?

Re: Question about DSD and processing

it's both --- on one hand it is hard to apply century long research of DSP to a one bit environment. on the other hand, the algorithms for PCM is very mature, highly efficient, and works really well. So why would one invest heavily on DSD?
