      public Sample(short[] frameData, byte[] residualData)
      Constructs a RELP Sample from its component parts
      Parameters:

      residualData - the residual data

    • Sample

      public Sample(short[] frameData, byte[] residualData, int residualSize)
      Constructs a Sample from its component parts
      Parameters:
      frameData - the framedata

    • Sample

      public Sample(BufferedReader reader, int numChannels)

  • Method Details

    • getFrameData

      public short[] getFrameData()
      Gets the frame data associated with this sample
      Returns:
      the frame data associated with this sample

    • getResidualData

      public byte[] getResidualData()
      Gets the residual data associated with this sample
      Returns:
      the residual data associated with this sample

    • getResidualSize

      public int getResidualSize()
      Returns the number of residuals in this Sample.
      Returns:
      the number of residuals in this sample

    • getResidualData

      public int getResidualData(int which)
      Returns the normalized residual data. You may not want to call this function because of the overhead involved.
      Parameters:
      which - the index of the data of interest
      Returns:
      the normalized data.

    • getFrameData

      public int getFrameData(int which)
      Returns the normalized frame data. You may not want to call this function because of the overhead involved.
      Parameters:
      which - the index of the data of interest
      Returns:
      the normalized data.

    • dump

      public void dump()
      Dumps the sample:

    • dumpBinary

      public void dumpBinary(ByteBuffer bb) throws IOException
      Dumps the samples to the given ByteBuffer
      Parameters:
      bb - the ByteBuffer to write the data to.
      Throws:
      IOException - if IO error occurs

    • dumpBinary

      public void dumpBinary(DataOutputStream os) throws IOException
      Dumps the samples to the given stream
      Parameters:
      os - the DataOutputStream to write the data to.
      Throws:
      IOException - if IO error occurs

    • loadBinary

      public static Sample loadBinary(ByteBuffer bb) throws IOException
      Loads the samples from the byte bufer
      Parameters:
      bb - the byte buffer to read the data from.
      Throws:
      IOException - if IO error occurs

    • loadBinary

      Loads the samples from the given channel
      Parameters:
      dis - the DataInputStream to read the data from.
      Throws:
      IOException - if IO error occurs

    • compare

      public boolean compare(Sample other)
      Compares two samples. Note that this is not the same as "equals"
      Parameters:
      other - the other sample to compare this one to
      Returns:
      true if they compare; otherwise false
