CompileError: WebAssembly.instantiateStreaming(): Compiling function #21 failed: Wasm SIMD unsupported @+3930 about free-music-demixer HOT 4 CLOSED

Here's the SIMD support for WASM across different browsers:

https://webassembly.org/roadmap/

SIMD (single instruction multiple data) is a way to optimize code for the CPU, and WebAssembly has some support for it (but it's not universal).

The funny thing is I didn't think I was using SIMD but I actually am.. I need to investigate that.

OK nevermind - it's on purpose: https://github.com/sevagh/free-music-demixer/blob/main/CMakeLists.txt#L14C243-L14C243

Let me see how slow it is without the simd flag.

OK, the good news is without this option, it's not that much slower: 7 min vs. 8 min on a medium-size track, 13 vs. 12 min on my biggest test track. I can release it without this option, which should be compatible with your device (and with a larger pool of devices in general).

I ended up deciding that I can only support SIMD for the implementation of Demucs. So, unfortunately, you'll need a way to use a different/newer browser
