In the May issue of Stereophile, I came across a new somewhat different from the previous when it comes to Room correction… see below:
Take note the new red highlighted path called ‘instructions’ from the decoder to the renderer. As for my understanding, this ‘instructions’ actually tell the renderer which up-sampling and de-blurring filters (There are possibly 16 of them) to select.
This ‘instructions’ will probably not able to survive if it goes through ‘optional immediate processing’ or called it DSP or any form of room correction. This open up one possibility that such implementation can also be applied to software decoding and rendering in one package.
