Battery life on FLAC 0 and FLAC 8 ...
LambdaCalculus:
So I figure that what you said before should be true. I have a few albums on my iPod in FLAC format, and I used Level 8 compression. On a fully charged battery, I can play the lot of them (7 albums in all), and still have about 50-60% charge left afterwards.

It's certainly true but I'm having a hard time recalling why I typed it. :x

The higher the number, the higher the compression, therefore lower disk usage (good for battery life) but higher CPU usage (bad for battery life).
The only way to find out which drains more current is to test it, but from personal experience FLAC 8 is overkill for only small gains in file size reduction.
FLAC 5 should do just fine. BTW have you done any ABX with lossy codecs? I'm an audio engineer and perfectly happy with MPC Q7 99% of the time.
MPC runs very efficiently on Rockbox (whereas Vorbis doesn't), so you get both low disk usage and low CPU usage.
If you're running Rockbox on an iPod of some description, the latest patches improve the performance of the MPC decoder even further.
LambdaCalculus:
The biggest draw for FLAC 8 with me was because it gives the smallest file sizes. I've tried some Musepack (MPC) files on my iPod, but for whatever reason, I've never been too big on Musepack. I'm a Vorbis man and I love the file format. I rip most of my CDs using Vorbis at Q5, and I'm very pleased by the results I get, especially compared to VBR MP3s.
But as they say, "To each his own". :)

I'm using Vorbis at the moment. Is it really a noticeable difference?
