Play bytestream on client site with web audio api

问题

I'm sending an stereo audiofile (WAV) via websockets and want to play it via the Web Audio Api. The Serversite technology is asp.net. Currently i have this:

 ws.onmessage = function(evt) {

        var d2 = new DataView(evt.data);

        var data = new Float32Array(d2.byteLength / Float32Array.BYTES_PER_ELEMENT);
        for (var jj = 0; jj < data.length; ++jj) {
            data[jj] = d2.getFloat32(jj * Float32Array.BYTES_PER_ELEMENT, true);
        }


        var buffer = context.createBuffer(1, data.length, 44100);
        buffer.getChannelData(0).set(data);

        source = context.createBufferSource();
        source.buffer = buffer;
        source.start(startTime);
        source.connect(context.destination);

        startTime += buffer.duration;

    }

With this i can hear the song but with A LOT of noise... i believe this might be because it is an stereo file and i only use 1 channel? If yes, how could i do it with two channels? I tried some things but the result was always the same or worse.

And i have another problem in understanding why it is working with Float32Array? In my first approach i used Uint8Array because i'm sending bytes to the client so i thought i would need Uint8Array to get the same values i send. But with Uint8Array i just hear noise and nothing from the song at all.

thanks for your help in advance!

Best Regards, metabolic
