iPod observation

[mc68k]

i thought of this the other day-- while not new to many it is an interesting thought.

my observation is the higher the bitrate of the songs the less your battery will last. This is due to 2 things:

o longer hardrive spinup for larger files
o processor/system will have to work harder to decode larger bitstream

So keep this in mind when you rip songs from CD (or the alternative ).

Shouldn't that be more drive activity instead?

or both: spin up takes the most amps but I did forget access, thx

This is why I almost always store songs on my iPod at MPEG 2 audio to save a huge loss in battery power.

Encode the songs from a CD using the following custom import settings in iTunes:
Mono: 32
Stereo: 64
Use highest VBR

The rest of the settings are up to you. The result is a 4 minute song is encoded at MPEG 2 audio at a little more than 64Kbps and takes up 1.8 or 1.9MB of Hard Drive space. iTunes can read MPEG 2 audio, and so can your iPod. Basically, it sounds like MPEG 1 audio at 128Kbps (or higher), but takes up about half the space. This is how you can get your Hard Drive to store 10 or more songs at around 4 minutes for a decent quality.

Did you ever observe that, mc68k?

interesting, KC

i didn't know thjat the iPod could do mpeg2 audio. i don't think i'd go lower than 128k encoding but your point is interesting.

when the firmware is updated to accomodate mp4, then we'll have the best of both worlds: more quality w/less space and more battery life.

it's nice that the device has so much flexibility (and quality)
