Any lossless codecs usable on the iPod?

Are there any lossless codecs that can be used on the iPod? I've seen methods of converting things such as .flac and other lossless codecs into .aac or .mp3 to then sync onto the iPod, but is there any way to have an actual lossless codec played on the iPod (a good chunk of my songs are in .flac and I don't like having the quality reduced)? I don't think that it would destroy battery life that much on the Touch to have larger files since it's flash memory based and it wouldn't take up battery since there are no spinning parts, right? Thanks in advance.

 

Wow, thanks for the really quick reply! Sorry I didn't check, I guess I should have done that first. But I still have another question; by using these larger, higher quality codecs, would a flash- memory based player such as the Touch be affected in terms of battery life? Because I would think not, since the whole reason HDD based players such as the iPod Classic lost battery life was because it had to spin the HDD more often. Also, is there any lossless codec that would work better than others with the Touch? Thanks in advance for answers.

 

Okay, thanks. I'm going to convert my .flac's to Apple Lossless now. I guess I could put up with the loss in battery life, though. I charge the iPod daily, and I've gotten used to the backlight being on the lowest setting, so 99% of the time it should get me through a day.
