     * Converts a 16 bit sample of type <code>int</code> to 2 bytes in an array.
     * <code>sample</code> is interpreted as signed (as Java does).
     * <p>
     * For little endian, buffer[byteOffset] is filled with low byte of sample,
     * and buffer[byteOffset+1] is filled with high byte of sample + sign bit.
     * <p> For big endian, this is reversed.
     * <p> Before calling this function, it should be assured that <code>sample</code>
     * is in the 16bit range - it will not be clipped.
     * <p> This is a reference function.
