Hi,
You get to set the sampleRate in the audio context you use, for audio
worklets samplerate is read only,
```
typedef int EMSCRIPTEN_WEBAUDIO_T;
typedef struct EmscriptenWebAudioCreateAttributes
{
const char *latencyHint; // Specify one of "balanced",
"interactive" or "playback"
uint32_t sampleRate; // E.g. 44100 or 48000
} EmscriptenWebAudioCreateAttributes;
// Creates a new Web Audio AudioContext, and returns a handle to it.
EMSCRIPTEN_WEBAUDIO_T emscripten_create_audio_context(const
EmscriptenWebAudioCreateAttributes *options);
```
from system/include/emscripten/webaudio.h
you can also have it EM_ASM_INT{console.log(sampleRate)} or something
equivalent (check out
https://emscripten.org/docs/porting/connecting_cpp_and_javascript/Interacting-with-code.html),
but you need to be careful and run this in the audio worklet scope not the
main one.
Hope it helps,
