ITunes data rate?

Before buying music from the iTunes store I'd like to get an idea of what quality to expect. My wife and I are audiophiles and music lovers and are somwhat particular about quality. We've discovered that when encoding CD's to MP3 we generally have to encode at 192 kbps or higher to get decent quality without too many artifacts, expecially with complex music such as orchestration or with lots of bright sounds like cymbals. (we've tried several different CODEC's). Some people here have said that AAC/.m4a produces better quality for a given data rate than MP3, but most of the serious objective tests I've seen indicate that any difference is either trivial or nonexistent.
So what is the bitrate for music on the iTunes store?
Thanks in advance.

At present the bit rate for iTMS tracks is 128 KBPS
Yuck!
One other thing to keep in mind is that the iTS store sells songs encoded at 128 kbps with the AAC codec which Apple claims is equivalent to a 160 kbps mp3-encoded file.
I'm not trying to sell you anything here because in the end it's going to be your ears that will decide whether the audio quality is acceptable or not but you could buy one or two tracks to see hear what you think. If you're happy with the quality, you can proceed to buy more. If not, you can write the whole thing off as a fairly inexpensive learning experience.
And if you're interested in a more technical comparison of the AAC and MP3 formats, have a look at this article .

Data rate of AAC file converted with iTunes 7.5.0.20

I have just noticed data rate of files converted to AAC with iTunes revision 7.5.0.20 deviate slightly from preset converting data rate in random manner. For example browser shows files with preset 192kBit/s data rate as 193 or 195kBit/s data rate, ones with 320kBit/s preset as 321, 322, 325kBit/s etc.
Is this a encoder bug or a music content dependent data rate adjustment?
Anyone a suggestion?
Thanks and best regards

ITunes Purchased HD Playback Data Rates

Recently downloaded a free "digital copy" SD movie and was wondering what the typical playback data rate range would be for purchased HD content. I.e., I assume it is still limited to TV1 compatibility but am wondering what the actual excursion range is like since I do not normally purchase content but am considering this option in the future.

If you purchased an HD show, did you sync the SD or HD version?

What is data rate consumption for iPods?

Since getting two iPod Touches, an iPhone 4, and an iPhone 5, our data consumption has skyrocketed. We are allotted 250GB of data use each month and we are currently sitting at 330GB with a week left.
I checked with netflix and the setting is at .3 (the lowest download rate). No one is home for 8 hours during the day, and we watch netflix about 3 times a week for about 2 to 3 hours.
we don't download movies and computer use is minimal.
We averaged about 120GB of data per month with the IP4 and 1 iPod, now it's skyrocketing.
What can I check on the devices to lower the download data rates?
Yes, our router is locked out, so no one is stealing bandwidth.
Thanks for any suggestions.

Look into this app - it seems written for you:

PE2 Data Rate too high

I am trying to burn a 15 minute video straight to the DVD. During the burning process (after rendering for about 10 hours) I got the following message: "The data rate of this file is too high for DVD. You must replace the file with one of a lower data rate. -PGC Info: name=, ref=Apgc, time= 00:07:44:23"
I successfully burned the same project a week ago; my only changes were adding some transitions and a few stills.
My project is video (most converted from VHS), music (ripped from CD or itunes), Audio (narrative recorded at home) and stills (almost all reduced to ~300Kb).
I am in the middle now of trying to burn to a file, but the error spooks me.
Any thoughts

Ned,
Some place, you have set the Data-rate above the DVD-spec. of 10 MB/s for ALL Assets, or have spikes above that. Now, since this is for all streams, Audio + Video, something below 8 works best. Then, if there is a momentary spike, it falls below the threshold of 10. In your Export settings, this has been set to high, either by you, or the program. PE is pretty smart about spikes, but can get fooled by the Assets, sometimes.
Check your output settings. I find that a setting of ~7 max. is better for player compatibility, though PE does allow one to go to 8 max.

How can I transfer my iTunes data from one computer to another? PS. My old computer won't turn on

I Recently bought a new computer and I need to transfer all my iTunes data from my old computer to the new one, how can I do that? And by the way, my old computer won't turn on

Hello Nousernamebrah
Well get get your music from your old computer to your new computer, the old computer would have to work and turn on to access the files to be copied over. You also can access any previous purchased music and download it to your new computer as well. Check out the articles below for more information.

Max Data Rate: AGP 2x?!

Bought myself a new MSI-KT6 Delta a few weeks ago (MSI-6590), and have had no problems until now.
First up, my GeForce 4 Ti 4600 decided to suddenly die. Random characters on the screen in text mode, flickery colours and corrupt pixels everywhere. Windows wouldn't detect it properly anymore.
Bought a new Powercolor Radeon 9600 XT with VIVO today. Downloaded the new drivers, and loaded up some Battlefield, all good. Runs nice and smooth. COD, Quake 3, etc, no problems at all.
Halo, however... BAD. Even with the basic graphics settings and no Pixel-Shading, it runs at 4 frames a second, and nothing I do changes this, from lowest to highest with Pixel-Shaders 2.0. Although there's a visual difference, it's just as slow.
So I loaded up ATI control Panel and used SmartGart to enable 8x and Fast-Writes... Rebooted, lots of flickering screen, and Windows XP is now software-rendering everything (Transparent menus take 100% CPU to fade in)
Wait for SmartGart to fix my graphics again, and it's all back to 4x and no fast-write.
Loaded up SiSoft Sandra, to check the settings in there...
Mainboard: "Max Data Rate: AGP 2x"
AGP Card: "Data Transfer Modes Support: 1x, 2x"
"AGP Bus is unused or AGP card not fully AGP compatible"
Er... should this be right? BIOS wont let me select an AGP speed, it's "Auto" and I can't select it. I'm a little concerned that my Motherboard may have been damaged! I'll go get the latest Halo Patch, but it doesn't change the fact that I can't use 8x or Fast-Write.
I'm a little apprehensive about flashing my BIOS, made more difficult by the fact that I have no working floppy drive.
CPU: AMD 2600+
RAM: 2x512mb DDR 333MHz Kingston
AlphaGremlin

Well, I updated the VIA drivers, and an updated Sandra. AGP is running at 8x, and Fast-Writes are enabled! I don't know what the hell SmartGart was going on about, but it appears to slunk away and disappeared completely from the ATI control panel since the last reinstall of drivers.
So there's one problem solved... but I don't know what's up with Halo... I can set it to the lowest settings and it still runs like an elephant with three legs, even with the -useff option for Fixed Function shaders... ah well, that's a matter for another forum, eh?
Interesting note: Sandra reports my 120gb drive as 605gb... should I be trusting it?

Data rate supported by 6533

Hello,
Can someone tell me what is the data rate supported by PCI 6533. i mean transfer the data from peripheral to the hard disk of the PC.

Hi,
Here are a couple Knowledge Bases that address this performance specification. I just posted the knowledge bases today so they might take a day or so before they are live. Hope that helps. Have a good day.

How to achieve high usb data rate with cRIO-9022?

Hi all,
I read the datasheet of NI-9022 and know that USB data rate can be 480Mb/s.
I want to transfer data with rate 3.6MB/s which is much slower than the spec, but the result is time out error.
I check my FPGA and RT code by save to RT disk and the result is pass. So I think my code should be correct.
Is that because the USB driver not installed into RT?
Should I install the USB driver into RT?
Or is there any other issue I haven't find?
Thanks a lot.

According to this document: Data Storage Options for CompactRIO, depending on many conditions, such as complexity of processor
requirements, USB data can be transferred off the controller at
approximately 700 KB/s.
Also, you don't need a driver to get a USB mass storage device to work on the cRIO. Have a look at this document:
Utilizing Features of the USB Port on My cRIO-901x or My cFP-22xx Controller
Not sure if these issues are causing timeout errors. What happens when you transfer data at lower speeds? Do you get timeout errors then?

Can I get my iTunes account to import my old harddrives iTunes data?

To clarify, I was stupid and didn't read iTunes has an option to very easily make it run off an external HD. I went in and sent all the music and apps to an external HD without using the consolidate option. I switched the iTunes data to the file but even though it will read new data that it saves onto the file, it won't read the ones that were there from before. Am I screwed, or can I still use the old data?

A computer with itunes is a basic requirement for iphone. It is not a stand alone device.
Changing the account is covered in the settings section of the manual:

I have a copy of my iTunes data and I'm looking to restore it all back into a new version of iTunes reloaded after a hard drive crash. How do I do this?

After having a hard drive crash, I've reloaded Windows 7 and all of my applications on a new hard drive. I have also downloaded and installed a new version of iTunes on my computer. I now want to restore all of my iTunes tracks, videos, movies, books, podcasts and all my playlists into the new version of iTunes from a back up of all of my previous hard drive before it crashed. I have tried importing the data but iTunes drops all kinds of data (artist names, album names, track number, etc.) and have to now manually go through all of my iTunes data (18,000 tracks) to restore the data. The data consists of a combination of purchased tracks (approx. 6,000) and my own personal CDs copied into iTunes. I need help badly here as I'm lost on how to proceed. Thanks.

I have a question about Data Rates.

Hello All.
This is a bit of a noob question I'm sure. I don't think I really understand Data Rates and how it applies to Motion... therefore I'm not even sure what kind of questions to ask. I've been reading up online and thought I would ask some questions here. Thanks to all in advance.
I've never really worried about Data Rates until now. I am creating an Apple Motion piece with about 15 different video clips in it. And 1/2 of them have alpha channels.
What exactly is Data Rate? Is it the rate in which video clip data is read (in bits/second) from the Disc and placed into my screen? In Motion- is the Data Rate for video only? What if the clip has audio? If a HDD is simply a plastic disc with a dye read by "1" laser... how come my computer can pull "2" files off the disc at the same time? Is that what data transfer is all about? Is that were RAM comes into play?
I have crunched my clips as much as I can. They are short clips (10-15seconds each). I've compressed them with the Animation codec to preserve the Alpha channel and sized them proportionally smaller (320x240). This dropped their data rate significantly. I've also taken out any audio that was associated with them.
Is data rate what is slowing my system down?
The data rates are all under 2MBs. Some are as low as 230Kbs. They were MUCH higher. However, my animation still plays VERY slowly.
I'm running a 3GigRam Powerbook Pro 2.33GHz.
I store all my media on a 1TB GRaid Firewire 800 drive. However for portability I'm using a USB 2 smartdisk external drive. I think the speed is 5200rpm.
I'm guessing this all plays into the speed at which motion can function.
If I total my data rate transfer I get somewhere in the vicinity of 11MBs/second. Is that what motion needs for it to play smoothly a 11MBs/second data connection? USB 2.0 is like what 480Mbs/second. So there is no way it's going to play quickly. What if I played it from my hard drive? What is the data rate of my internal HDD?
I guess my overall question is.
#1. Is my thinking correct on all of these topics? Do my bits, bytes and megs make sense. Is my thought process correct?
#2. Barring getting a new machine or buying new hardware. What can I do to speed up this workflow? Working with 15 different video clips is bogging Motion down and becoming frustrating to work with. Even if only 3-4 of the clips are up at a time it bogs things down. Especially if I throw on a glow effect or something.
Any help is greatly appreciated.

Data rate DOES make a difference, but I'd say your real problem has more to do with the fact that you're working on a Powerbook. Motion's real time capabilities derive from the capability of the video card. Not the processor. Some cards do better than others, but laptops are not even recommended for running Motion.
To improve your workflow on a laptop will be limited, but there are a few things that you can try.
Make sure that thumbnails and previews are turned off.
Make sure that you are operating in Draft Mode.
Lower the display resolution to half, or quarter.
Don't expect to be getting real time playback. Treat it more like After Effects.
Compressing your clips into smaller Animations does help because it lowers the data rate, but you're still dealing with the animation codec which is a high data rate codec. Unfortunately, it sounds necessary in your case because you're dealing with alpha channels.
The data rate comes into play with your setup trying to play through your USB drive. USB drives are never recommended for editing or Motion work. Their throughput is not consistent enough for video work. a small FW drive would be better, though your real problem as I said is the Powerbook.
If you must work on the powerbook, then don't expect real-time playback. Instead, build your animation, step through it, and do RAM previews to view sections in real time.
I hope this helps.

I had to have the hard drive replaced on my computer and i lost all my iTunes data and I hadn't backed up my music. can I still transfer music from my iPod to a new iTunes?

Music Rescue also works as far as restoring your playlists etc. I've used it twice, you can use the Quick Recover mode, but have to click continue trial (something like that) allot, cp. to purchase option. Otherwise diesel is right as far as restoring via your purchase history.

How can I sync my iphone to a new computer? My phone is the only source of my phone and itunes data.

I would like to use my iphone to instal and restorel all my phone data to a new computer. I lost the back up of my old computer itunes data. How can this be done?

Syncing to a new iTunes library or computer will erase your iPhone. Only if you back up your phone manually before syncing, you can restore your device from that backup again. A manual backup does not include the sync process.
Do this to back up manually:
Disable autosync in iTunes, connect your phone to your new computer and right click on it in the device list and choose backup. iTunes will backup your device without syncing.
Transfer your purchases the same way, choosing "transfer purchases" this time.
When you connect your phone for the first time, all media content will be erased. But you can restore your settings and app data from your manual backup afterwards.
Don't forget to set up at least one contact and event on your new computer to be able to merge calendars and contacts when you sync the phone for the first time.
Music is one way only, from the computer to your device, unless you bought the songs in itunes and transferred your purchases.
There is 3rd party software out there, but not supported by Apple, see this thread: http://discussions.apple.com/thread.jspa?threadID=2013615&tstart=0
