Implementation of Sound.loadPCMFromByteArray:

    public function loadPCMFromByteArray(Bytes:nme.utils.ByteArray, samples:Int, format:String = "float", stereo:Bool = true, sampleRate:Float = 44100.0):Void {

        // http://www-mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/WAVE.html
        var wav:ByteArray = new ByteArray();
        wav.endian = Endian.LITTLE_ENDIAN;

        var AudioFormat:Int = switch(format) {
            case "float": 3;
            case "short": 1;
            default: throw(new Error(Std.format("Unsupported format $format")));
        };
        var NumChannels:Int = stereo ? 2 : 1;
        var SampleRate:Int = Std.int(sampleRate);
        var BitsPerSample:Int = switch(format) {
            case "float": 32;
            case "short": 16;
            default: throw(new Error(Std.format("Unsupported format $format")));
        };
        var ByteRate:Int = Std.int(SampleRate * NumChannels * BitsPerSample / 8);
        var BlockAlign:Int = Std.int(NumChannels * BitsPerSample / 8);
        var NumSamples:Int = Std.int(Bytes.length / BlockAlign);

        wav.writeUTFBytes("RIFF");
        wav.writeInt(36 + Bytes.length);
        wav.writeUTFBytes("WAVE");
        wav.writeUTFBytes("fmt ");
        wav.writeInt(16); // Subchunk1Size
        wav.writeShort((AudioFormat)); // AudioFormat
        wav.writeShort((NumChannels));
        wav.writeInt((SampleRate));
        wav.writeInt((ByteRate));
        wav.writeShort((BlockAlign));
        wav.writeShort((BitsPerSample));
        wav.writeUTFBytes("data");
        wav.writeInt((Bytes.length));
        wav.writeBytes(Bytes, 0, Bytes.length);

        wav.position = 0;
        loadCompressedDataFromByteArray(wav, wav.length);
    }
