iPod touch converting higher bit rate songs to 128 kbps aac

[ali.mofadal]

i am running low on space so i am thinking of converting higher bit rate songs to 128 kbps aac i have few questions about it

1- will my original mp3 will be affected ?
2- will i notice difference in quality ?

The only thing I noticed that was different when I used that option was that it took MUCH longer to sync, as Im assuming it does that conversion on the fly. It does free up a decent amount of space though.

Bear in mind that Im not an "audiophile", but to my ears it was the same.

what about my original mp3 files, i don't them to be converted, i just the songs in the ipod only

Converting them on the fly keeps the files original on the computer, and small on your iPod.

As far as quality goes? I compare it to photo files. If you look at a photo taken using a 1 megapixel setting, the normal size photo on the computer looks fine. Increase the size of that photo and you will see it pixellate. Look at that same photo taken at a 10 megapixel setting and zooming will give you better quality and detail.

Listen to a song at a lower bitrate with high quality earphones at a higher volume vs that same song at a higher bitrate in the same conditions, thats where one will notice it vs another.

It's lossy compression, like the one you applied to your post. You lose quality.
