New lossless codec comparison (Jan '13), Lots of test results, lots of graphs Options

I transcoded my FLACs from -8 to -5 and there was *very* little size increase. This will likely help out my battery life at a tiny size cost. Thanks for the input guys.

saratoga can probably speak as to the specifics of that player, but on Porta Player devices the difference in decode speed would equal ZERO, not a little, but zero power savings as the CPU doesn't clock lower than 30Mhz. Whereas the size difference would equal (probably insignificant but) real power consumption differences due to increased storage access. Flash obviously cuts the power consumption of storage access down vs spinning rust, but the number is real.

I've got a bit of a noob question. I just RockBox'd a Sansa Clip+ and I'm trying to find the best lossless encoding that balances file size and battery life. Right now I'm using FLAC-8. I'm assuming that on the decoding graph a higher value on the X-axis equates to better decompression ie. better battery life?

I've ran a test on my clip+ with an album encoded with flac -11 (CUETools's flaCL) and the same with wavpack -hhx and the difference was only about 10 minutes in runtime, so I'd say lossless encoding options don't affect battery life that much anymore.
