What is the smallest file size/format for songs? AAC vs MP3 etc?

i need to change the size of my songs so i can fit more on my ipod but im not sure what format is smaller. they are AAC at the moment. is that the smallest or can they go smaller without disturbing the quality too much? i should be able to fit 1000 on my ipod but i can only get about 400 so i need to compress them. what should i make them and how do i do it??

I already answered your other question, but I'll post here, too.



'When it says that it's supposed to hold up to 1000 songs, it's talking really low quality music in a low quality type of audio file.



If you're not much into quality, though, then you can open up your iTunes and go to Edit -%26gt; Preferences -%26gt; Advanced -%26gt; Importing and see how you're importing your CDs (that is assuming it's off CDs).



If you're REALLY concerned with space, keep it at .aac files at 128 kbps, or maybe .mp3 128kbps. If that's already what it's at, you don't wanna go much lower than that because you'll seriously be able to hear the quality of song drop.



To see what bit rate your songs are currently at, add a 'Bit Rate' column by going to View -%26gt; Options -%26gt; check Bit Rate. Take a gander. Maybe even take a look at the File Type, by doing the same thing as the Bit Rate above.



Essentially, anything below 128 kbps for an MP3/AAC file is pretty poor. Anything above 192 (if you're attempting to save space) is a little high, and you might wanna consider re-ripping/re-getting at a lower bitrate.



If you have any WAV/FLAC files...then that's where the space issue is. Those are lossless files, meaning that, on average, they're gonna be about 35 MBs per song, which is about 7 times what a normal song at 320 kbps is.



Feel free to email if you need any help/have more questions.'



What really makes the difference is the bit rate of the song. You shouldn't go much lower then 128...but if you're at 192 or so, you can probably drop it a bit without noticing too much of a difference.
