Leftover Blocks

The leftOverSamples field of a compressed sound header contains a pointer to a leftover block, defined by the LeftOverBlock data type.



 
TYPE LeftOverBlock = 

RECORD

    count:              LongInt;

    sampleArea:         PACKED ARRAY[0..leftOverBlockSize - 1] OF Byte;

END;

count: The number of bytes in the sampleArea field.
sampleArea: An array of bytes. This field contains samples that are truncated across invocations of the compression algorithm. The size of this field is defined by a constant.



 
                    CONST

                        leftOverBlockSize               = 32;
