Hi, my name is Jan Wilczek and I am an audio programmer and a researcher. Welcome to WolfSound!
WolfSound's mission is to provide high-quality, informative, and entertaining videos, articles, and courses on how to process sound by exploring mathematics, applying algorithms, and creating code in various programming languages. Topics include sound synthesis, digital signal processing, programming languages for audio (C, C++, Python, Rust), and audio effects. I am also sharing tips on how to learn fast and effectively. Make sure to visit https://www.thewolfsound.com/.
WolfSound enables everybody to learn about audio programming!
ABOUT THE VIDEO
In this video, I explain what is Single Instruction, Multiple Data (SIMD), how is it useful in DSP, and show a small example of code using SIMD that adds two vectors together.
💡 In short, SIMD instructions let us perform operations on more than one variable at once using dedicated processor registers.
💡 Different processor architectures and models have different SIMD instructions available.
💡 SIMD instructions can make your DSP code significantly faster at the cost of
➡️ code complexity.
➡️ portability,
➡️ expert knowledge on processors.
In case of any doubt in understanding, please, refer to the article above or ask a question in the comments 🙂
