-  How the codec works:
-  --------------------
-
-  The volume is increased to increase the dynamic range of the audio signal.
-  Each sample is converted to a-LAW with only 16 steps of level resolution.
-  A pair of two samples are stored in one byte.
-
-  The first byte is stored in the upper bits, the second byte is stored in the
-  lower bits.
-
-  To speed up compression and decompression, two lookup tables are formed:
-
-  - 16 bits index for two samples (law encoded) with 8 bit compressed result.
-  - 8 bits index for one compressed data with 16 bits decompressed result.
-
-  NOTE: The bytes are handled as they are law-encoded.
