I want to resample an audio file in my local environment to 16k.

I have written the code but it does not work.
Also, I don't know if the code is wrong or how to receive the audio file after resampling.
I would appreciate any advice you could give me.

`

<script>  

    var audioData = [test.mp3]; //audio file in my local 
    var bufferSize =1024;

    var context = new AudioContext();


    var oldSampleRate = context.sampleRate, newSampleRate = 16000;



        processor.onaudioprocess = function(e){

            var inputData = e.inputBuffer.getChannelData(0);

            var ResampleData = interpolateArray(inputData, inputData.length * (newSampleRate/oldSampleRate)  );


            bufferSize = inputData.length * (newSampleRate/oldSampleRate);

            var bufferData = new Float32Array(bufferSize);
                for (var i = 0; i < bufferSize; i++) {
                    bufferData[i] = ResampleData[i];
                }
            audioData.push(bufferData);

        };


        //How do I receive the finished data?
        var newaudio = "???"

</script>`
