    Hello, guys.

    I wanted to convert all my songs stored in my iTunes library to AAC 160 vbe, making the whole songs uniform in format and bitrate, because today they are in multiple formats and bitrates, a mess.

    But, I wanted to do it automatically, you know, using some app like automator, or something, because know, if I do it inside iTunes, i end up with two songs: the original and the conveted, and, I had to delete manually all the original archives...

    Considering that I had 30 gig of songs, do it manually would take ages...

    Can anybody help?

    Thanks in advance!


    P.S.: please, forgive any grammar or ortographic error, I live in Brazil and writing in english is very hard to me... :eek:

    I don't know how to do it, but remember that upping the bitrate increases file size and the quality stays the same...

    This is very simple to do in iTunes.
    Set the AAC format you want in the preferences and then select all of your songs in iTunes and select from the Advanced Menu>Convert Selection to AAC. Now sit back for a few hours as the conversion is done.

    Then set the view by date created and delete out all songs not made on the day of conversion.

    But I will say that this will only make the quality of the music the same or worse. It cannot make the quality better. And I would recommend against doing this.

    I just want to chime in that the best thing you can do is to remove the bit rate field from the browser so you just don't see it. There's really nothing "messy" about having files in different formats, and you're going to (a) waste a lot of hard drive space upconverting 128 files to 160 and (b) not get any benefit out of it.

    What is the bitrate of the music files that you are starting with?

    If they are currently 128 kbps mp3 files, for example, it won't provide any improvement to re-encode them at 160 vbr aac. If you've got 256 kbps mp3 however, it might make sense to use the vbr encoding.

    I just encoded my CDs at 128 kbps AAC, and they sound great.

    To delete them you can just make a smartplaylist that includes only files with kind that doesn't contain AAC.

    I wouldn't bother doing the conversion though.

    Thanks, guys.

    My motivation in doing it is that a made a lot of downloads, and they are in the vast majority 320 kbs Mp3.... so, I thought i would save some space in the HD, and, when I burn CDs to listen in my car's stereo, it will be easyer to make it only AAC, with quality.

    Thanks again!

    Thanks a lot for your tip. I will try it today. I'm planing on doing it because I want to save some space in the hdd, and to mahe it easyer to burn CD's to listen in my car's stereo. I believe i will use 128 AAC, because I can't notice diference between 128 and 160 AAC.

    And, I'll be abble to fit more songs im my iPod nano 4gb...

    Thanks, again.
