320kb/s AAC w/ eq on or apple lossless w/ no eq?(This for ipod)

Thanks

It would make the most sense if anything with thw EQ on just drains them batteries...

Lossless is only about 2 to 3 times that bitrate.

Thanks for the reply. I know that eq will eatup extra current, but file size of lossless is about twice as big as 320kb/s so the harddrive has to spin up more frequently.

Both more than 224 kbps. I see the argument for lossless (and use it myself), but I don't quite get the compromise-for-size go lossy ... then max it out! mindset.

You'll get an extra couple hours approximately with 224 and below over 320 and ~3-4 extra on 320 over lossless. EQ not taken into account. That's all depends on iPod model though. MP3 should in theory give a gain also with lower CPU cycles over AAC, but never tested.

I never figured that lossless was such a hit on battery life, would anyone know how much of an offset lineout provides, over using the headphone out?

The bigger the file size is, the less memory space to spare for buffering songs, so the HDD needs to spins more often. All these problems are because, the lack of ram in Mp3 players. Bring me the future, I want it now!

Some say that AIFF/WAV is more battery life friendly than lossless because it requires less CPU cycle to decode it. Yet, uncompressed files are HUGE, and the hardrive will have spin almost every five minutes. ???

why would eq eat battery? It's just an extra piece of software running on a chip that is already in use. Unless it requires another peripheral or the DSP is capable of dynamicaly controlling it's clock rate.

eq's are powered by little green fairys inside your ipod

there are no chips or electricity involved it is just plain magic

The power consumption of an IC is affected by activity as well as clock rate (and voltage, and a host of other factors). The more you've got going on inside, the more power it consumes.

Especially with the variable-speed chips used on current iPods
