Applications :: AAC Versus Lossless - Finding The Difference?
Jul 27, 2004
I listened to a few U2 songs encoded with AAC and Apple Lossless. Listening through the standard ipod ear buds, I honestly could not tell the difference.
Has anyone been able to notice a discernible improvement with Lossless? If so, what type of music/speakers were you using?
I was considering picking up this stand for my uMBP:
One thing that concerned me was having higher CPU temps with the lid closed.
I read a thread a few days ago that said there is no CPU temp change between lid closed and lid opened. And after doing some of my own testing I now believe that information is FALSE.
I use smcFanControl to control fan speed and monitor CPU temp.
Before using smcFantControl to boost my fan speed to constantly run at 3,400RPM, my CPU temp was 10-20 degrees (celsius) higher, on average.
I was just curious what the main differences were between the applications Deeper and Onyx? Onyx seems to be the same thing, with a few more features. Is there something that Deeper can do, that Onyx can't?
Also one more random question.. does Transparent Dock work on OS X 10.4.9, and does it allow you to change the color like Cleardock?
I'm looking to finally upgrade my Mac Pro to use an SSD as a boot drive, and I've been eyeing the OCZ Vertex 2 drives as a result of the beloved Sandforce controller. My question is, the only OCZ drives I've been able to find at the price point I want in my area are the Vertex 2 3.5 120 gig editions.

Is there any reason NOT to get this over the 2.5 version? I'm not planning on putting it in the optical bay as both are in use, and would just go in a regular hard drive bay. It's unfortunate that I wont one day be able to use it in my Macbook Pro should I ever upgrade however, beyond this am I suffering any penalty by going with the larger size?
I have a Mini 2.53 I'm using as a HTPC and It's great. I also have a 17" MBP 2.66 which never leaves my desk. I do mostly photo editing. Anyone know if I'm gonna see much difference if I slim down to just the Mini? I'm thinking of selling the MBP for the cash.
Also, I can run my dual Apple 23" Displays on the mini and cant on the MBP.
So when the windows 7 beat was launched, i ended up choosing to download the 32-bit version as I knew it would run, and I wasn't sure if I was compatible or not.
1. I have a 20" iMac 2.4GHz 2GB RAM etc. Is my computer capable of running 64-bit?
2. Whats the difference between 32-bit and 64-bit? Is 64-bit faster?
Today I noticed that there is really lots of color difference when I look at an image on the web when i use firefox in comparison with firefox. For example the red collors are really really bright on firefox but in safari they look not bright at all. Actually safari is more accurate. How to fix color when using firefox (my main browser) are there like certain setting you guys recommend?
How much speed difference is there? Battery I take it is almost double in real life, actually using the MBA. I get barely 3 hours with moderate use on my Rev B and I take it most people get close to 7 with similar usage?
I currently purchase TV shows for the kids and rent movies (Apple TV) but until the Apple iTunes store offers the choice of lossless files (like other online music stores).. I'll continue to purchase CDs. Chris Jacob is correct the "LP" series should be ALAC - Apple Lossless.
Its an interesting article, published last year;[URL]
If Apple really wants to recreate that "feel" of buying a record, I have to feel like I'm buying something that isn't just higher quality, but also permanent. If I buy a lossy AAC file from the iTunes store today, not only do I know that it's inferior to the same $15 CD, but also that I'll have to chuck it once AAC is put out to pasture.
I've just ordered a MBP 2.4Ghz with 7200rpm 750GB drive, I will be adding either a single 8GB memory stick (total of 10GB) or a 16GB kit. I'm looking for my first SSD use as a boot drive for OSX and potentially Win 7 in BootCamp and hope I can get some counsel on model selection and configuration. I read that SSDs suffer a performance drop (sometimes significant) as the drive fills up. Also there are both 256GB and 240GB drives.Â
1) Are there models that maintain performance over time? Is there a specification that indicates how performance drops as the drive fills up?Â
2)Â Is there a performance difference (current / long-term) between 256 and 240GB drives?Â
3) Does an abundance of RAM improve performance and / or longevity? Â
4)Â How much space (if any) should be kept free for swap files in OSX / Windows?Â
5)Â With 240 / 256GB SSDs, how much usable space is available after formatting?Â
6)Â Is there a difference in performance based on file format NTFS vs. HPS+?
7)Â Do I need to be concerned about major name brands (Intel, Samsung, OCZ, Kingston, etc.) being incompatible with MBPs?Â
8)Â Are some SSDs easier to install / configure / maintain on a MBP than others?Â
9)Â Are there any issues I should be aware of regarding the installation or use of a SSD that would impact my MBP's warranty?Â
Based on performance, reliability and 5-year warranty, I've been attracted to the Intel 520. I've also read good reports on the Samsung 830. One review indicated that the 830 maintained performance over time while the 520 experienced a significantly greater drop.

I highlighted about 23 songs from an album, and clicked on create apple lossless version. I now have two copies of each song. Shouldn't it have asked me if I wanted to delete the original version? I guess I need to delete each one individually?
I still have a great number of AIFF files in my music library.
I'd like to convert them to Apple Lossless, as it's the same sound quality at half the space.
I know you can create a copy of any file in another format, but it sounds quite complicated. First you have to create a copy, and then you need to delete the "original" AIFF file.
Can't I just convert an existing file without a copy, keeping also the play counts?
It used to work: You highlighted the songs you wanted to create an Apple Lossless version of, and they would show up underneath the AIFF version.
No longer.
iTunes 9 still could do this.
iTunes 9.0.3 loses them. It processes them, puts them into the right folder, but you can't see them in iTunes.
Questions:
1. Can I downgrade to iTunes 9.0 where this bug wasn't present?
2. Or do I have to manually import into iTunes? (This would erase the playcount, I suppose)
Or is there any other way around this bug? (or isn't it a bug, but a feature that has been disabled by Apple for whatever reason?)
PS: I found a place where I can download iTunes 9.0.1 for OS X. Are there any possible problem when installing an older version over a newer version, e.g. in regards to the library?
For almost the last year I have been using an Airport Extreme on 2.4b/g and and Airport express in my room to extend my wireless network. I also have a usb hdd configured to back up my macbook using time machine. Well I have a new roommate moving in and he has his own extreme and two expresses.
I have some questions on what would be the best way to consolidate our networking devices. I considered us selling our extremes and getting the new time capsule so both of our macs can use 5ghz while my girlfriends dell uses the 2.4.
Is there a noticeable speed difference between time capsule backup vs hard drive to extreme connected via usb?
How to - Creating and maintaining Lossless and Lossy music libraries in iTunes 9 A forum member has asked for information on how to create a new library for his music collection and below is my attempt to help. Having done this myself and never finding a complete step-by-step guide, I?ve attempted to make one of my own. Many others have helped me along the way so this is my way of giving back. Unfortunately, I don?t have my MBP right now and won?t have a Mac around for about two months. Please feel free to add feedback, tell me where I?m wrong, what?s missing or offer other ways of accomplishing these tasks. Once I get MR member input, I will update this post to reflect the best current practices for creating and maintaining two separate libraries for your lossless and lossy music collection. At the bottom of the post I list a couple of known issues and have a couple of questions so please chime in.
I'm looking at second hand 2009 quad mac pros. I'm not sure if 2.66 has a massive disadvantage over the 2.93. The thing is, I'm buying this for quite a long run (I work with audio/ Logic pro). I'm thinking that the 2.93 will be more future proof? Does anyone have any experience with the two?
I am seriously considering a Mac Pro but I am stuck if I want a single or dual processor. Ill barely do video editing, Ill run fusion, photo stuff, etc...
I'm going to eventually buy a reburb white Macbook and I am contemplating between the 2.1GHz and the 2.4. As far as the ram and hdd are concerned, I plan on putting a bigger drive in and upping the ram to 4gb, so the only difference left is the .3Ghz.
The money saved by going with a 2.1 would just about cover the 4gb and a good 320GB HDD.
My plans for this laptop are: surfing, some work in Windows (thus the ram), itunes, iweb, iphoto... no gaming planned, I'm just not a gamer.
I plan on purchasing an iMac in the next couple days and was wondering is USB 3.0 really important? Will there be some type of way us current 2.0 users get 3.0?
I understand that some of the early core 2 duo's are different than the current core 2 duo's being used in the current 13" MBP's. I understand that some are T8000 series or T9000 series (I think??).
My question really is what is the difference between the earleir C2D's used and the current ones. Some of the earlier ones seem to have more L2 cache, do the newer ones run on a lower voltage? Have a different chip? Are quicker/slower?

MacBook Air:
Runs OS X
I really can't think of much more than that for the Air. I love OS X and thats why I haven't bought either. Mind you this is ignoring that Apple may release an update soon for the MBA cause if they do then I have my answer. But if they don't I don't know which I want! I love aluminum, but I am not a fan of the rounded corners apple put on the MBA.
