Save a binary

This does NOT work, because you need to encode the wave file. But there's a lib that does that: https://github.com/mattdiamond/Recorderjs

HTML

<a id="a1" download="test.wav" type="audio/wav">file</a>

JavaScript

var
      buffer = new ArrayBuffer(8) // allocates 8 bytes
    , data = new DataView(buffer)
;
// You can write uint8/16/32s and float32/64s to dataviews
data.setUint8 (0, 0x01);
data.setUint16(1, 0x2345);
data.setUint32(3, 0x6789ABCD);
data.setUint8 (7, 0xEF);

saveAs(new Blob([buffer], {type: "example/binary"}), "data.dat");

var aaa = btoa(data);
console.log(aaa);

var a = document.getElementById('a1');
console.log(a)

a.href = "data:audio/wav;base64,"+btoa(data)
console.log(a.href)
