hi there,

I have a bit of a mistery here...I've read in the iPod's manuell that using the equalizer will drain the battery faster since more CPU power is needed...therefore theiy suggest turning this feature on in iTunes. Anyway, I expected that iTunes would run the song through a filter or something to apply these equalizer settings so that the iPod won't have to do this on the fly...however this doesn't seem to be the case.

This is what I tried:

I added the exact some song twice to iTunes, however I applied a equalizer setting to one of the songs. After that I transfered both songs to the iPod. After that, first, I listened to both songs (not using iTunes) and they sounded exactly the same. Then, I opened both songs in Adobe Audition...seemed to be the ecaxt same thing again.

However, according to the modifying date something changes were made on the one song I applied to EQ settings...it also sounded different in iTunes.

Therfore, is there somthing like an option were you can change the sound of a song, similar to what mp3Gain does? Or was it simply explained wrong in the iPod manuell and they ment whenever there is a predefined EQ setting this one will be used no matter the current iPod EQ-setting? But even then, I still wonder why the file was altered after I applied that EQ setting in iTunes...

Any idea?

thanks

It probably just updated the ID3 tag with a field telling iTunes which EQ settings to use on playback.

Precisely.

so it won't give me a better battery life then...thank you
btw.: it does indeed add a id3v2 tag!
