java pcm to wav

Question

I have a pcm file, and I want to convert it to a wav file.

Is there any suitable api or code for this?

Answer 1

I cannot yet leave comments, but be aware that the get16BitPcm method in devflow's answer is [oddly] scaling the input data. If you already have 16 bit pcm data to write to the wav file, the method should look something like this:

public byte[] get16BitPcm(short[] data) {
    byte[] resultData = new byte[2 * data.length];
    int iter = 0;
    for (short sample : data) {
        resultData[iter++] = (byte)(sample & 0x00ff);
        resultData[iter++] = (byte)((sample & 0xff00) >>> 8);
    }
    return resultData;
}
