Voice in voice note got heavy pitch as compare to original voice

[Furqan2]

Describe the bug

When we send a recorded voice note in the chat it got heavy pitch and voice is clearly diffrent from original voice..

[antoine92190]

Indeed the voice sounds a bit strange... I will check that

[antoine92190]

I cannot reproduce anymore... Do you still have the issue on your side?

[Furqan2]

Yes , you can test in the demo also

[Furqan2]

There is still same pitch issue

[antoine92190]

On the demo, which room do you see the issue?

[Furqan2]

"Professor" and "dsds" both .... I have check my S3 bucket also the stored Audio pitch is high as compare to original voice.

I have the same issue on my side. I'm using vue2. Can I use any configuration of bitrate or something as prop (audio-bit-rate and/or audio-sample-rate) that improve the audio performance? I'm new in this audio stuff...! Thanks

[antoine92190]

I think the audio code is defective. We should find a better alternative to it. Anyone is welcome to work on that, otherwise I will try to fix it when I have time

For explanation, this actually uses the sampleRate of the microphone, not a fixed one.

@antoine92190 did you find the solution for this ?

I'm now also getting a deprecation error in the latest version of Chrome [Deprecation] The ScriptProcessorNode is deprecated. Use AudioWorkletNode instead.

And yes my audio pitch is also wrong.. it makes me sound like a chipmunk.

@antoine92190 any chance you will implement @TheNoim's fix?
