Floor 1 Decode
Dear All,
Floor 1 decoder uses FLOOR_fromdB_LOOKUP table. The purpose of this table
is not clear to me. It is also not explicitly explained in the vorbis
specification.
As i have understood is that it is used to dequantise the "Y" values
which are decoded from the bitstream during curve synthesis. Is this
correct ?
If so why does the table have only 256 elements ? This would imply that
the "Y" value decoded from the bitstream should has a range from "0" to
256. ? Does the encoder ensure...
