(While AVX is an Intel instruction set, it has also been adopted by AMD will be available in their upcoming Bulldozer processors. )Ĭode which is optimized for AVX vectorization capabilities can work with 256-bit vectors, allowing working on 8 32-bit floating point values per iteration. The paper features a real world case study of SONAR X1 code that was optimized in to take advantage of the benefits of the 256 bit AVX instruction set. If you have an Intel CPU from the Sandy Bridge processor family, it supports AVX and SONAR X1 will take advantage of it. While the paper is technical and requires an understanding of some low level programming, it also offers insight into the nuts and bolts of whats involved in optimizations for Intel CPU architectures in a modern DAW.

We’re excited with our synergetic relationship with Intel, which allows us to take advantage of their bleeding edge technology in ways that directly beneft our users, allowing them to squeeze the most power out of their systems. This is a whitepaper ( Utilizing Intel® AVX with Cakewalk SONAR X1) which I co-authored with Intel engineer Rajshree Chabukswar, highlighting the advantages of optimizing for the Intel AVX chipset, with a focus on digital audio processing in a modern DAW like SONAR X1.
