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;

Field Description

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;
