I have mine set at 160 AAC but I don't keep most of the music that I have on cd on my Macs. I did notice the sound when a few were put up higher say at 192 AAC but thats just me Does this really matter coming from an iPod? Or is the big diff. only from your home sound system?Reeves
So should I just stay with 128 AAC?
If you cannot get a source of higher quality, stay with 128kbps AAC.Reeves said:So should I just stay with 128 AAC?
I already have difficulty telling the difference from AAC at 128kbps and 64kbps already for most songs. I suppose AAC+ will give me the following dilemma: keep my 3rd gen. 10GB iPod that now holds "20GB" or switch to a blue iPod mini that now holds "12GB" (which is still about "4GB more" than my needs).combatcolin said:And what happens when Apple release iTunes with AAC+?
Then i'll re import 5000+ songs at a lower bit rate and keep the sound quality, unless you have an expensive sound system and a good pair of ears its all a bit of a waste of HD space.
That's a big if... and when they're imported/ripped as Lossless then it's much easier to convert them to lossy formats like AAC/MP3 within iTunes. A couple of seconds to push the right buttons and sometime later they're all converted.Reeves said:I do have all the CD's, but since your all talking about AAC+ I think I'll just hold off for that instead of uploading them all loseless and then 6 months or so later have to change it again.
You set your iTunes importing preferences to the format you wish to convert to (AAC in this case, you choose the bit-rate).Reeves said:How do you convert lossless to AAC?
Anywhere between 50-75% depending on the source material it seems.tfaz1 said:If I use the File>Import command and have Apple Lossless enabled, how much could I expect to trim a 1GB concert down to?
Yes, it will possibly even fit onto a data CD for archiving.tfaz1 said:Thanks Blue... So I can expect a 1GB file to go down to anywhere between 750-500MB?
I'm guessing that apple loseless will be similar in size to shorten and flac, since those are also loseless formats.tfaz1 said:While we're on this subject, I'm downloading live concerts from etree.org (relax, they're all LEGAL). Most of them are around 1GB per concert. Once I've converted the .shn files to .aiff, I would like to compress them. If I use the File>Import command and have Apple Lossless enabled, how much could I expect to trim a 1GB concert down to?
Thanks for any help!
I'll give it a go Blue, it has to do with the way the brain processes complex audio signals, we all suffer from a phenomena called "masking" which basically means we can't always hear quiet sounds as they are simply obscured by louder ones (or even HF sounds obscuring LF sounds)Blue Velvet said:Anywhere between 50-75% depending on the source material it seems.
Perhaps Wintermute or another audio genius will come and tell us what exactly determines these variable compression results.
Try a couple, see what happens...
Only very slightly I'd think, the probelm is when the filesizes get to the point where the disc is spinning up during a single song to load the next section into memory, sure 256 is twice the size of 128, so the disc (theoretically) is worked twice as hard, but id doesn't equate to a 50% increase in battery use, as the disc is only a part of the total load on the iPod's power system.Fredstar said:I have started ripping my albums at AAC 256 because i reckon it sounds noticeably better than AAC 128, my question is when i play 256kbs on my 20gb ipod will it affect the battery life significantly?
