Thank you for developing the javascript version of World!!
I built WorldJS.js as described in the README, and tried it on a simple web server, but the following error came up.
It seems to be an error related to the detached ArrayBuffer in WorldJS.wasm.
I have confirmed that the Dio_JS function, written before CheapTrick_JS, can run and output an f0 value.
How can I resolve this?
Uncaught TypeError: Cannot perform %TypedArray%.prototype.set on a detached ArrayBuffer

Thank you for you great product.
I tried to use this library with audio api.
But I'm not familiar with emscripten. so I could not do it .
Could you give me a hint?
there are my code ( Partially)
audio.js
import { default as Module } from "./WorldJS.js";
/**
*
* @param {Float32Array[]} input
*/
static featureExtract(input) {
// input is 128 * 32 float32ArrayArray
// so I must change to Float64Array
const buffer = new Float64Array(bufferSize * bufferingLength);
for (const [i, f32] of input.entries()) {
for (const [j, value] of f32.entries()) {
buffer[i * bufferSize + j] = value;
}
}
const { Dio_JS } = Module;
const { f0, time_axis: timeAxis } = Dio_JS(buffer, sampleRate, framePeriod);
console.log(f0) // f0 is always zero array like [0,0,....]
argument of featureExtract(input) come from mediaStream like mic.
I think I could not send buffer propery.
the first argument type of Dis_JS is emscripten::val
Do you know the way to use this function from javascript?
I'm looking forward your reply.
