I can't think of anything on the architectural side that would prevent us from optimizing Web Audio using a DSP or SIMD, because it boils down to implementing pure signal processing functions using SIMD intrinsics or assembly.
Simply implementing the specialized functions in a separate file and calling the right function based on the chip capabilities (like we do for SIMD) should be enough. iirc, we tried to group all the signal processing functions in the same file, or could do so rather easily. But maybe you are talking about something else, in which case, what kind of chip do you have in mind? Paul.
