Hey everyone, back when I imported hundreds of my CDs onto iTunes about two years ago, I had no idea there was a way to control the quality of the imported song. Since I have figured out how to do that, I have been importing songs at a higher bitrate (256) and I was wondering if there is a program out there to take my lower quality songs (around 128) and upconvert them to something a little higher, say 156 or even 192. Thanks as always.
 
Yeah, thats kinda what I thought. You can't make something out of nothing, right?
 
This brings in a feature I really really like in iTunes: insert a CD you have already imported, and it will offer to replace them.

Yeah, I noticed that. I have done what you said with a few songs already...
 
I must be deaf or something, but I can't notice a difference between 128 AAC, 128 MP3, or Apple Lossless.
I've played the 3 simultaneously in Quicktime and quickly switch to one from another but still they sound the same.

So, to add my two cents, you can't that you want to do. You'd have to re-rip your music at a higher bitrate.

Wow - have you been to a lot of concerts with no earplugs or something? Try ripping a jazz track or any electronic music involving percussion. At 128 MP3 the drums sound tinny and hollow. High hats have reverb and crackle to them. AAC sounds marginally better and lossless - major difference. I started ripping music about 7 years ago and kick myself for selling CDs after ripping at 128. 256+ is the only way I go now.
 
it could be the playback system. depending on how good your speakers or headphones are, sometimes it's hard to tell. esp on crappy consumer computer speakers.

but if you train your ear enough, you can tell difference. i can most of the time on my TiBook speakers.
 
Well hey, I played a song at 128 side by side with the same song at 256 and it sounded the same. But hey I guess I can slowly re-import them to a higher quality.
 
taking a song encoded at 128 and turning it into a song encoded at 192 would be like using an 800x600 background image stretched to fit your 1600x1200 monitor.

that's a good analogy. not exactly the same, but easier to imagine. very well put.

Not only that, but that would also be like saving that stretched 1600x1200 image. You end up with a bigger file at a lower quality.
 
Upconverting is just a waste of space with no improvement in quality. Don't do it.
