In my local version and also the web demo - in the worklet's samplerate is different from the effect: ``` this.effect = new this.Superpowered.AutomaticVocalPitchCorrection( this.samplerate // 44100 ); this.effect.samplerate // 48000 ``` I notice there's a commented out line: ``` // Ensure the samplerate is in sync on every audio processing callback // this.effect.samplerate = this.samplerate; ``` Uncommenting this seems to make it work OK.
