Managing two bit-rates per song

Is there an easy way to manage two bit-rates per song? I wish iTunes would do this itself, under the covers. Similar to versions in Aperture. What I want is to keep an Apple Lossless version for Apple TV, but have a low bit-rate version for my iPhone and iPod (due to space limitations). I know I can store two versions of the same song but they are treated as two songs, so if I change a rating or a keyword it happens only to the one song. Or I have to manage two versions of the same playlist. Etc.

The short answer is no, theres no good way to do what you want. This has been a shortcoming of iTunes for years. Those of us interested in having a lossless library were forced to use lossless on out mobile devices, which doesn't make sense at all, or to maintain two parallel libraries.
What you guys really want is called on the fly transcoding. The idea is you store a high quality version (ideally lossless) of the track on your computer and that when this track is to be synced to a device it is transcoded to a more efficient format.
This is something that most media players have been doing for years, and yet Apple shows no interest in implementing such a feature.

How can I reduce the bit rate of songs in my Music Library to enable me to

At the moment i can only fit about 1300 songs on my iphone and also have used up half the space on my 120gb Classic with 7000 songs which is a lot less than what i was told would fit on. so............
How can I reduce the bit rate of songs in my Music Library to enable me to fit more songs onto my iPhone or iPod Classic.. and what is the minimum rate that i should stick to in order to retain good sound quality.

For existing tracks, see:
http://support.apple.com/kb/HT1550
For CDs you import in the future, change the Import settings in the iTunes -> General preferences.
As to what will be a good bit rate, that's going to be up to you and what quality you find acceptable, but many people find that 128 kbps AAC is the optimum balance between small file size and quality.

Is it possible to raise the bit rate of songs higher than 256 on iTunes? If not what should i use or do to raise the bit rate of songs?

Is it possible to raise the bit rate of songs higher than 256 on iTunes? If not what should i use or do to raise the bit rate of songs?

Songs you rip from CD can have their bitrate increased to a maximum of 320Kbps from the iTunes preferences; alternatively, the default encoder can be changed to a lossless one. Songs from other sources have a fixed maximum bitrate.

Increasing bit rate of songs on Synching with iPhone?

The standard bit rate of 128 kbps doesn't seem high enough for some types of music and the quality can be poor. I used to have full aiff files on my phone but could obviously only get a handful of albums on, the quality was superb but overkill. Is there a way of synching with a better bit rate, say 200 kbps?

Hello.
I found music sites like Beatport, Audiojelly and so on, which offer 320 kbps as the standard encoding bitrate for all of their music.
Buy from them. They specialize in exactly what you are doing - "electronic and trance music" - which iTunes does not.
A couple of more stores in the same vein are JunoDownload and DJDownload.com. You have plenty of choices.

After I download a 256 kbps song using ITunes Match, how do I get it to play on my computer at the higher bit rate once I turn ITunes Match off again?

After I download a 256 kbps song from the cloud using ITunes Match, how do I get it to play on my computer once I turn ITunes Match off again? I have been using ITunes Match for awhile now to increase the bit rate on songs to 256 kbps. Once I download the songs at the new bit rate, I turn off Match because I want to eliminate duplicates. Usually there is no problem. This time, however, 278 of my songs lost their file association and were unplayable unless I locate the song files within my computer. These are songs purchased from Amazon. In order to play them again in ITunes (Match is now off), I must locate each song file individually (I've tried to do it in bulk but have not succeeded) but now the bit rate has returned to the lower number BEFORE I matched the song. I should have never used Match in the first place. Any ideas, anyone?

I discovered that the NEW 256 bit file does reside on my computer, in the ITunes files (My Music/ITunes/ITunes Media/Music. So I can bring the songs back as 256 kbps, and I have been successful now at locating more than one file at a time, by clicking on the "find other missing files" tab in the popup window. Previously, I'd been going back to my Amazon files, and not only was I unable to bring back a 256 version, but the popup window would not locate similar files. So while I wish ITunes Match would automatically associate the ITunes Match file, at least I can retrive the file association without hours and hours of work.

What is table field name for order status report of rate per unit and bal

hi i want to make FS for order status report i almost get all table and field but i don't get only two field rate per unit and balance value table field didn't get please help me searching in field and table
i want to develop my status report

Hi,
Check tables VBAK and VBAP wherein you will get all header and item details.
VBUK and VBUP for header and line item statuses.
KONV would give you rates/pricing details for each condition type determines in the sales order.
VBAK-KNUMV = KONV-KNUMV is how you relate both of them.
Hope that helps.

PROBLEM with 24/96 bit-rate USB DAC that worked fine until I plugged in two

I'm using a late 2008 15" Macbook Pro that I bought Jan 2009 right before the SD card models came out. Mac OSX 10.6.4 and iTunes 9.2 are installed. I have a Nuforce Icon HDP and a CEntrance DACport 24/96 bit-rate USB DAC (external sound cards) that still work great right now. Note - 16 bit/44 Khz is CD quality, and these 24/96 files are hi-resolution downloads that are closer to SACD or DVD audio.
I have been evaluating a new third 24/96 USB DAC plugged directly into the Macbook USB port (no hub) which has been working fine for over 2 weeks with 24/96 bit-rate lossless music files in iTunes. Audio Midi Setup is set for 24/96 to match the music file's resolution. After making suggestions to the manufacturer they made some improvements and sent me a new version to listen for the differences.
I listened to the new one for a day and it worked fine, but when I plugged in the original test sample into the second USB port at the same time as the new one in order to compare them, the sound became garbled and noisy. This never happened when either one was plugged in by itself. Note, if I make changes to the DAC's bit-rate in Audio Midi Setup I usually close iTunes first and then re-open it when I am done.
Upon hearing this new problem I unplugged both of the new USB DACs and plugged just one of them back in, but now it causes iTunes music playback to pause when one is plugged in and set for 24/96 in audio midi setup. Prior to plugging in both at the same time, either one worked just fine by itself. There is no reason when unplugging one or the other that they shouldn't start working again. But now I can't play any 24/96 music through either one anymore. In quicktime player the songs don't pause like with iTunes, but there is no sound coming through even with just one DAC plugged in at a time. Then I discovered that if I go into Audio Midi Setup application and lower the bit rate to 24/48 then iTunes will resume playing again and I can hear the music fine with iTunes or Quicktime player.
Basically, my Macbook Pro has now lost the ability to play 24/96 bit rate with either of these new USB DACs, when they both worked fine before I plugged them in at the same time. More confusing is that they use the same USB receiver chip as in one of the DACs that I mentioned above in the first paragraph, and both the HDP and DACport still work fine at 24/96 bit-rate. It's only these two new USB DAC that require me to lower the bit rate in Audio Midi Setup to 24/48 in order to listen through them, and this wasn't a problem as recently as yesterday!
The computer is acting like some setting needs to be wiped out - it's DEFINITELY NOT the USB DAC's that are faulty because they still both work fine at 24/96 on my wife's iMac (I'm afraid to try plugging in both at the same time to the iMac in case I screw that Mac up too).
I have reset the PRAM a few times, and this doesn't fix the problem. I thought maybe the com.apple.audiomidisetup.plist file could be corrupted and deleted it, but that didn't help. I don't know what to try next to get the Macbook to start fresh when trying to use these devices, short of having to re-install OSX.
Please, does anyone have a suggestion of how I can make the Macbook forget it ever saw these two USB DACs, and let me start fresh so they start working normally again? I do dozens of reviews for Head-fi.org and I can't afford to have my Macbook Pro compromised like this, which could prevent me from doing some reviews or evaluating new products.

UPDATE:
As noted in the first post, both of these newer USB DAC work fine at 24/96 on my wife's iMac, so it's clear that they didn't both become defective when I connected them to the Macbook Pro at the same time.
Resetting the Macbook Pro PRAM didn't help, so I removed the hard shell laptop case to get to the battery and remove it, then reset the SMC. After that I could use the original DAC at 24/96 again, but only IF it was plugged into the rear USB port. If I plugged it into the front USB port then the sound was garbled and filled with noise. This was a vast improvement over no sound at all.
Then I switched to the replacement/updated DAC, but I got no sound at all from either USB port at any bit-rate. And returning to the original DAC again now results in no sound again.
Sigh... I will reset the PRAM and SMC again, and see how far I can get with this. I'd still love some help. Thanks!

[Bug] iOS 5.1 missing covers after "convert higher bit rate songs to" with iTunes 10.6

All my music has covers in iTunes Library. But after i updated to iOS 5.1 they are missing on my devices.
It happens every time i check "convert higher bit rate songs to 192/256 kbps" on iTunes 10.6 (40) on my Mac.
On the screenshot (iPad 2010 running iOS 5.1) Bon Iver's album copied by default settings, and Coldplay's album converted to 192 kbps.
BTW on my old iPhone 3G (iOS 4.2.1) all covers are OK even when convert feature is ON.

I have solved it by unchecking (momentaneously till apple fix it) the "Convert higher bit rate songs" option.
I know that it need more space but i don't have too much music synced so.. it isn't a problem for me..
I have this problem because i'm using the "manually manage music and videos", i'm not using the auto sync option because iTunes always try to copy my new apps to my mac even having that option unchecked...
Now we have iCloud... i don't know why apple still have not deleted this feature!
Anyway... i have solved it momentaneously.
Apple.... come on!

Using the "Convert higher bit rate songs to 128 kbps AAC" feature...

I recently discovered the "Convert higher bit rate songs to 128 kbps AAC" feature and used it to copy my entire 70 GB music library to my 64GB iPad. The music library now occupies only 45 GB. Awesome!!!
Unfortunately, the whole process took well over 24++ hours on my quad core Windows 7 computer (takes about 6 seconds per track). Questions:
1. Is it possible to speed up the process? Even though I am using iTunes 64-bit version, it seems that at no point is more than a single core being used at 33%. Seems to me like overall 8% of the CPU (33% / 4) capacity is being used for the conversion and 92% is being left idle. Is this just bad programming or is there anything I can do to speed up the process? Others see similar problems?
2. Now I have already started dreading the day, I need to restore my iPad (e.g., when OS version 4 becomes available). I would hate to have to do this process all over again. Should I need to restore my iPad, is there anyway I can force iTunes to back up the 128-bit AAC versions on my computer and restore it up from there?
Any insights into both these questions will be deeply appreciated.
Cheers,

Thanks for the response.
So, I am wondering why iTunes uses only 8% of the processor power in converting the songs.
Possible reasons not to grab more of the CPU power (1) maybe the process is I/O bound due to all the writing, and is not processor limited? (2) since conversion is almost always a background program, and the user will typically have other things going on, maybe it intentionally limits CPU use?
I ran a few quick experiments (out of curiosity) and think the answer is #2. No apparent technical reason but potentially a limitation introduced by Apple's engineers to maintain a good user experience (for some people at least). I fired up 4 instances of dbpoweramp and ran multiple conversions and found that the process goes faster than what iTunes can do by an order of magnitude. With luck, someday Apple will have an option for users to select how much of processor bandwidth to be allocated for the conversion.

How do I change the bit rate for dls?? How times can I download one song??

I'm new to iTunes. I already downloaded 3 songs when I realized that the default bit rate is 128Kbps. I tried changing the bit rate to 192Kbps with a (Variable Bit Rate) checked.....unfortunately when I downloaded the next 2 songs the bit rate turned out to be the same.
Do I have to restart Windows or iTunes before downloading again?
And now that I have 5 songs with a lower br than I wanted... in order for me to have(download) the song at the higher bit rate...Is it possible to download one song more than once?
Thanx.

You have no choice as to bit rate when purchasing from the iTunes Music Store. The official bit rate of all tracks there is 128 kbps (a very few have been reported to be at higher rates, but that's not a choice you can make, it's how the track was encoded by the record company). The setting in the iTunes Importing preference is for tracks you import from CDs only and has no effect on iTMS purchases.
Is it possible to download one song more than once?
No. Except in extraordinary circumstances, the iTMS allows only one download per purchase.
Forum Tip: Since you're new here, you've probably not discovered the Search feature available on every Discussions page, but next time, it might save you time (and everyone else from having to answer the same question multiple times) if you search a couple of ways for a topic before you post a question.

HT204406 how do I download higher bit rate songs from itunes match to replace the lower bit rate I have on my itunes library?

I have itunes match and I have about 500 songs that were ripped at 128kbps. I have been tolf that I can replace them via itunes match to improve them to 256 or 320?
I have put them into a playlist in my itunes library and I want to know how I can upgrade their bit rate via itunes match. Can anyone help me?

Sid,
With the device connected, click the Summary tab and you will see the "Convert higher bit rate..." option. Set it to 128. See picture below:

If I have converted my purchased iTunes songs to a lower bit rate what will happen when I join iTunes match? Will they match up or will these be stored as duplicates of the same song?

If I have converted my purchased iTunes songs to a lower bit rate what will happen when I join iTunes match? Will they match up or will these be stored as duplicates of the same song?
I ask because I primarily use my work laptop which has limited space so I usually convert my purchases to 160k from 256k in order to save space. I want to sign up for iTunes Match but I'd like to know before I do so I can understand how I will have to set up my library.

What I may do is start a brand new library there, copy my tracks from my work laptop using Home Share and then the script to get things in sync before starting over again there too.
Why create a new library? Just add the tracks from the laptop to the existing library on the Mac.
crichton007 wrote:
I was just hoping to hear definitively whether or not there was some sort of intelligence built into iTunes Match that would match these up...
How do you mean? If you down-convert purchased tracks you've fundamentally changed the files so iTunes can no longer recoginize them as "purchased." And, indeed, they no longer are since they are brand new files. Of course these new files will only be "matched" or "uploaded."

ITunes 7 and Shuffle:"Convert higher bit rate songs to 128kbps AAC" broken

This has become unusably slow in iTunes 7. Is this fixed yet? Does anyone have a workaround?

I have the same issue but with my iPad 2 and iPhone 3GS. Songs play fine in iTunes. If is uncheck Convert higher bit rate songs to 128kbps AAC the no more scratching sounds on my devices.

HT1535 How do i convert higher bit rate songs to 128 kbps AAC

I am trying to sync selected songs to my Iphone 5 from my itunes library. I have recently taken my computer to be fixed and all of my music documents were taken off but the files were replaced shorty after. I re-downloaded itunes and it is up to date. My iphone is also on the ios 7.0.4. Whenever i plug my phone in to be synced it never goes past the "waiting for changes to be applied" step. While my phone was still connected i went to the "On this iphone" tab and clicked the autofill button and a message came up that said i must convert higher bit rate songs to 128 kbps ACC to allow the songs to be copied to my iphone. How do i do this? Also, once this is done will it solve my problem with transfeering my songs from my library to my iphone?

Changing bit rate, etc. on songs already in iTunes library

I've done this many times before, but I keep forgetting how, and I haven't found the HELP menu to be of help. Anyway, I have a recording that Id like to share, but its file is too large, so I have to reduce it by decreasing the bit rate. How do I do this?
