Web5 nov. 2024 · Another stunning piece of code Bastian. The mulshift32 is your 32-bit x 32-bit signed multiply. Only the top 32 bits are used which is why I keep looking and looking. To calculate each 16-bit PCM output uses 32 mulshift32s. I'm sure you can see how much just 1 cycle less would save.
