IPod storage by time or file size?

I recorded a song and it turned out to be 16.5 mg and apparently thats a lot for a song to be. Anyhow, I was wondering if when I upload this song to my iPod, will it minimize my amount of storage a LOT or do iPods minimize storage by how long the song is? So basically, is it all about file size or length of a song? If it's file size, is there any way I can perhaps make the file smaller? Also, does the file size change when changed into MP3, because right now that big file is in WAV. Thanks a bunch!IPod storage by time or file size?
The song is that big because it was encoded at probably 320kbps. A 4 minute song at that quality is somewhere around there. If you convert it to mp3 select 128-192 kbps those are reasonably good bit rates. The iPod doesn't support WAV files so convert it. When you transfer The song the whole song with th e same bit rate will be the same on the ipod. The rule is higher bit rate = richer sound quality + Large file size.IPod storage by time or file size?
it is the file size.

hents why they say 2gb, 4gb. 8gb,,80gb...160gb



1024mb is in a gigabyte. that is why they say ho big the memory is not how long many minutes of music it will holdIPod storage by time or file size?
Ok first of all, iPods take MP3 and MP4 format. the other thing is that there is no such thing as a MG. you probably mean MB. If you have a one Giga Byte iPod (GB) it will hold approximately 1000 Mega bytes (MB). a song that is 16.5 MB is a big song and will take up about 17/thousandths of your iPod space. Im not sure how your planning to convert it to MP4 format though.IPod storage by time or file size?
it goes by file size.
