how to collect the raw microphone data during recording ?

[woosungchu]

While I try to make my previous cordova project to nativescript style, which can analyze
raw audio data in real-time, this open-source help me a lot.

But I think it hasn't proper API to collect the raw microphone data
like .. [ 0.003434 , -0.12355 , 0.0002323 ....... ] this.

Can you answer me if it have API or not?

I don't think so but if you can point me to a Cordova implementation (I assume this is a cordova plugin you've used) I can check the native APIs being used and see what needs to be addressed with this plugin. Thanks

this demo is what I used.
https://github.com/edimuj/cordova-plugin-audioinput/blob/master/demo/file-demo.js

evt.data will return raw microphone data ( [ 0.003434 , -0.12355 , 0.0002323 ....... ] )

function onAudioInputCapture(evt) {
    try {
        if (evt && evt.data) {
            // Increase the debug counter for received data
            totalReceivedData += evt.data.length;
console.log(evt.data)
            // Add the chunk to the buffer
            audioDataBuffer = audioDataBuffer.concat(evt.data);
        }
    }
    catch (ex) {
        alert("onAudioInputCapture ex: " + ex);
    }
}

Or you can just clone and follow readme.md file
