I've been in this endeavor with Surface Book 2. While the results where good, the CPU usage for software DSP killed the entire effort. Microsoft is using intel's DSP accelerator to do this. While linux technically can use intel's audio DSP I never had enough time to dig into it

What DSP accelerator does Intel have?

my guess is Intel provides software windows uses to accelerate common dsp operations with simd/sse etc.
