trying to use pitch detect but failing

[pm100]

in index.html

<script src="https://unpkg.com/aubiojs"></script>

I have this in ts (ignore the name, this is not a worklet, it starts one , now that scriptnode is deprecated), using your .d.ts file

class PitchDetectWorklet {
    audioContext!: AudioContext;
    running: boolean = false;
    pitchWorklet!: AudioWorkletNode;
    cb: (note: number, freq: number) => void;
    options: PitchDetectOptions;
    stream!: MediaStream;
    aupitch!: Pitch;  <<<<==
    au!: Aubio; <<<< ====

and then

        this.au = await aubio();
        this.aupitch = new this.au.Pitch('default', 128 * (this.options.buffersize || 10), 1, this.audioContext.sampleRate );

this all works fine.

But then when I get a buffer from my worklet I do

                var buff = ev.data.buff;
                var freq = that.aupitch.do(buff);

I always get

   Uncaught RuntimeError: null function or function signature mismatch

I think I have copied everything from your tuner demo. I have run out of ideas

fails edge and chrome

chrome gives better debug stack
