Apologies in advance if there is A. another thread like this out there I was unable to produce through several searches, or B. a more appropriate forum category in which this should be posted. Ugh. I began this week with a supposedly fun task: setting up the brand new ipod touch we got my dad for Father's Day with all his favorite music. Since my giant library is all kinds of disorganized, I got TuneUp to clean it all up. Unfortunately, TuneUp only recognizes mp3 and AAC files (suckage), so I then got MediaHuman Audio Converter to convert all my non protected mpeg's to mp3. That finished, I was psyched to add back all the newly converted mp3's, and even deleted (only out of iTunes, thank goodness) my entire library before doing so in the interest of a clean start. Just kidding! Every single sone appears in iTunes as an MPEG Audio File. Every one. Attached screenshot shows "get info" results for same file in finder (MP3) and iTunes (MPEG Audio). I went online and found out there's some sort of coding issue (not too tech savvy when it comes to media files) that has caused others to complain of mp3's recognized by iTunes as Quicktime files. I assume it's the same issue here, only with MPEG Audio. In lieu of messing with Terminal - the only other option I could find online - I proceeded to act on the following instructions from the iTunes Help files: Save a copy of a song in a new file format You can convert a song to a different file format (and keep a copy of the original). For example, you can save a copy of a compressed song file such as MP3 or AAC in an uncompressed song format (AIFF or WAV). When converting from a compressed to uncompressed file format (for example, from MP3 to AIFF), you shouldnt notice any reduction in sound quality. However, when converting between compressed formats (for example, MP3 and AAC), you may notice a reduction in the sound quality. For the best results, if you want your music encoded in a different file format, import the music again from the original source using the new encoding format. Important: You cant convert iTunes Store purchases unless theyre iTunes Plus songs. To convert a songs file format: Choose iTunes > Preferences, click General, and click Import Settings. In the Import Using pop-up menu, choose the format you want to convert songs to, and click OK to save the settings. Select one or more songs in your library and choose Advanced > Create Format Version. The song in its original format and the newly converted song appear in your library. Elated to have followed all the steps (seemingly) without a hitch, I once again deleted the library and re-imported all of the mp3 file versions of my songs. Guess what? No change. Same thing happened. I even did the last step (advanced-save copy as mp3) since merely importing the files with the new settings didn't work, but this, too, did nothing. I'm on a deadline and what was supposed to be fun has turned into a total nightmare. I'm spending precious hours I need to work for clients (i.e. billable hours) running on a hamster wheel. I actually shelled out the money for the paid version of TuneUp (stupid and impulsive, you betcha) because it seemed to do all that I needed and I didn't take the time to learn what formats were not supported. Had I bypassed the whole "buy an app to save time" step I would have finished changing all the file names and organizing my library by now. If anyone has an idea as to how this can be fixed, I'd be so grateful. Thanks in advance for time spent responding.
