Examples of java.nio.ShortBuffer

java.nio.ShortBuffer
A buffer of shorts.
A short buffer can be created in either of the following ways:
- {@link #allocate(int) Allocate} a new short array and create a bufferbased on it;
- {@link #wrap(short[]) Wrap} an existing short array to create a newbuffer;
- Use {@link java.nio.ByteBuffer#asShortBuffer() ByteBuffer.asShortBuffer}to create a short buffer based on a byte buffer.

    ByteBuffer dest = ByteBuffer.allocateDirect(audio_bytes.length);
    dest.order(ByteOrder.nativeOrder());
    ByteBuffer src = ByteBuffer.wrap(audio_bytes);
    src.order(ByteOrder.BIG_ENDIAN);
    if (two_bytes_data) {
      ShortBuffer dest_short = dest.asShortBuffer();
      ShortBuffer src_short = src.asShortBuffer();
      while (src_short.hasRemaining())
        dest_short.put(src_short.get());
    } else {
      while (src.hasRemaining()) {
        byte b = src.get();
        if (format.getEncoding() == Encoding.PCM_SIGNED) {
          b = (byte) (b + 127);
