iOS is not supported. I don't have any benchmarks, but my low powered MOTO E Android phone seems to encode without much trouble.

I would be curious to see if there are any performance gains to be had. Javascript operates with floating point, and incoming audio is float 32 so I would be sceptical that converting data to fixed point would have any advantages.

Good points.
I'm also happy to hear that it works well even for MOTO E.
Sorry for the stupid question, but why is IOS not supported? I know that IOS can't play ogg, but is there any problem for the use case where audio from the microphone is encoded and sent to a server?

iOS does not allow browser access to the microphone.
Also note that the compilation of opus with emscripten has all SSE optimizations disabled. I receive compilation errors when trying to add them. I was able to compile speex with SSE optimizations and SIMD, but it performs about 10x worse than without.
