11The decoder is based on ffmpeg-svn r18110 : Mar 21 2009.
12Some changes were done on in order to use static VLC tables
13according to this commit :

16The decoder had been modified to use fixed-point arithmetic.

18TESTING
19
20The test program should compile in any Unix-like environment using the
21command "make -f Makefile.test".
22
23For ARM targets add -DCPU_ARM to CFLAGS in Makefile.test to make use of
24the asm ARM optimisations in rockbox's mdct library.
25
26For Big-endian targets, change -D"ROCKBOX_LITTLE_ENDIAN=1"
27to -D"ROCKBOX_BIG_ENDIAN=1" in Makefile.test.
28
29Running "./atractest file.rm" will decode the audio data to a WAV file
30called "output.wav" in the current directory.
