Michael Giacomelli 87d3dde15a Fix corrupt when repeatidly playing very low bitrate WMA files. 
The LSP feature in WMA requires that the noise table values be
doubled verses when it is not used.  Unfortunately, the previous
code would double the same values every time a LSP file was
decoded without first resetting them to their original values.
Change the code to check if the values are already doubled, and
then double/halve them as needed.  This is still a bit ugly,
in the future consider using the built in rockbox dither instead
of a lookup table.

Fixes playback when skipping back and forth between low and high
bitrate WMA.

Build Your Own Rockbox

1. Check out 'rockbox' from SVN (or extract a downloaded archive).

   $ svn co svn://svn.rockbox.org/rockbox/trunk rockbox

     or

   $ tar xjf rockbox.tar.bz2

2. Create a build directory, preferably in the same directory as the firmware/
   and apps/ directories. This is where all generated files will be written.

   $ cd rockbox
   $ mkdir build
   $ cd build

3. Make sure you have sh/arm/m68k-elf-gcc and siblings in the PATH. Make sure
   that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
   a particular version depending on what player you are compiling for. These
   can be acquired with the rockboxdev.sh script in the /tools/ folder of the
   source, or will have been included if you've installed one of the
   toolchains or development environments provided at http://www.rockbox.org/

   $ which sh-elf-gcc
   $ which perl

4. In your build directory, run the 'tools/configure' script and enter what
   target you want to build for and if you want a debug version or not (and a
   few more questions). It'll prompt you. The debug version is for making a
   gdb version out of it. It is only useful if you run gdb towards your target
   Archos.

   $ ../tools/configure

5. *ploink*. Now you have got a Makefile generated for you.

6. Run 'make' and soon the necessary pieces from the firmware and the apps
   directories have been compiled, linked and scrambled for you.

   $ make
   $ make zip

7. unzip the rockbox.zip on your music player, reboot it and
   *smile*.

If you want to build for more than one target, just create several build
directories and create a setup for each target:

   $ mkdir build-fmrecorder
   $ cd build-fmrecorder
   $ ../tools/configure

   $ mkdir build-player
   $ cd build-player
   $ ../tools/configure
