The retune of compression levels makes this test fail. This is due to a few approximations used in the encoder that determine which LP coefficient should result in the smallest file. Differences are usually very small, but in my case this resulted in compression level 6 giving a 3 byte bigger file. This patch lets the compression test pass even if the a compression level results in a file that is up to 10 byte larger than the previous level Signed-off-by: Erik de Castro Lopo <erikd@mega-nerd.com>
