JAva byte配列とshort配列の相互変換

注意byte配列の長さは2の倍数でなければなりません

    public static short[] toShortArray(byte[] src) {

        int count = src.length >> 1;
        short[] dest = new short[count];
        for (int i = 0; i < count; i++) {
                dest[i] = (short) (src[i * 2] << 8 | src[2 * i + 1] & 0xff);
        }
        return dest;
    }

    public static byte[] toByteArray(short[] src) {

        int count = src.length;
        byte[] dest = new byte[count << 1];
        for (int i = 0; i < count; i++) {
                dest[i * 2] = (byte) (src[i] >> 8);
                dest[i * 2 + 1] = (byte) (src[i] >> 0);
        }

        return dest;
    }
