Converting to 128 kbps

In iTunes 9.03, if you have an iPod, you can choose to convert all higher bit rates to 128 kbps, so you can put more songs on your iPod. What I want to know is: does this conversion affect the actual file, or converts iTunes it specially for the iPod (so the file on your Mac, with the higher bit rate, isn't gone)?

After much testing, I have, to my satisfaction, verified that there is a problem with iTunes 9.1.1 (11) new [Convert higher bit rate songs to 128 kbps AAC] function. After enabling the function for the first time, and all songs had been converted, I discovered that all songs with lyrics had been REMOVED from my iPod touch (64GB 3rd Generation). Thereafter, at EVERY sync, the SAME songs were "updated" but never showed up on the iPod.
I removed the lyrics from the songs, re-synced, and the songs were transferred to the device.
I then added-back the lyrics and synced the device. The songs were then placed on the iPod WITH the lyrics but the songs are now, again, re-updating (each song) at EVERY sync.
I plan to wait until an update to iTunes is released. If this issue is not corrected after that, I will RESTORE the device and report back.

Error -50 when trying to convert to 128 Kbps AAC

I try to convert all my files to 128 KBPs but about halfway through one of the songs gets an error (-50) and it wont go on. I wanted to do this because I heard it makes the songs take up less room and my iPods almost full. If it helps any I'm using the latest version of iTunes on Windows 7 65 bit.

Unless you happen to catch the name of the song it's syncing, I don't see how you are going to narrow this down.
While syncing, if you click on the ipod in the left list, you can make the little triangle point down. Then click on the word Music underneath that. (Not the main music library, in other words)
There will be little circles next to each song when that song is getting synced. There will also be the song name in the top oval. If you happen to catch that song's name, you could uncheck it and itunes won't try to sync it.

Change the convert to 128 kbps before transferring to iPhone option?

iTunes gives you the option to convert all higher-bitrate audio to 128 kbps AACs before transferring to my iPhone. Great, except I'd prefer a little higher quality. Is there any way to make it, say, covert to 192 kbps VBR AACs instead?

if you're converting from a lossless format, you could use this:
[_*Lossless to AAC Workflow v2.2*_|http://dougscripts.com/itunes/scripts/ss.php?sp=losslessaccworkflow]
Two scripts assist with importing/managing Apple Lossless or AIFF audio files and sending converted AAC copies to a mounted iPod set to "manually manage songs and videos".
*Lossless to AAC Workflow (CD->iPod):*
Imports each enabled CD track as an Apple Lossless or AIFF file
Makes a converted AAC copy of each imported file
Adds the AAC file to iPod, deleting the original AAC from iTunes.
*Lossless to AAC Workflow (iTunes->iPod):*
Makes a converted AAC copy of each Apple Lossless or AIFF track selected in iTunes
Adds the AAC file to iPod, deleting the original AAC from iTunes.
In this way you can keep archived lossless files on your hard drive, and manageable AAC files on your iPod.
+Yes, iTunes 9.1 will auto-encode tracks to iPod, but only 128 kbps AAC; these scripts enable use of your Custom AAC encoder setting.+

Music Skips Some Songs After Choosing "Convert higher bit rate songs to 128 kbps" Option

I have so much music and choosing "convert to 128 Kbps" option makes it from 18 Gb to around 6 gbs but sometimes a few songs are ther

Meg St._Clair wrote:
"Convert" tends to be a confusing term. What iTunes does is make another copy of the track at the lower bit rate for transfer to the Shuffle. Your original, higher bitrate file remains untouched.
Actually, iTunes converts the track on-the-fly while loading it on the shuffle. NO copy of the downconverted track is kept. The same process will occur IF you decide to delete the track from the shuffle and then happen to want to put it on the shuffle again.

Syncing with 128 kbps conversion

Whenever I try to sync my playlist, I have around 50 songs that somehow don't make it. I always get an error pop-up after: "iTunes could not copy "[Song Name]" to the iPhone "[iPhone]" because the file could not be converted."
I have it set so that files will be converted to 128 kbps when they're transferred over, and they sync from a specified playlist. Almost all the files that can't be converted are MPEG files...does anyone know why this isn't working out?
Thanks in advance.

For what it's worth, I have the same problem. I get that same message for 27 songs. No idea how to fix it, though I've fished around on the web a bit.
Sorry I can't be more helpful.

Hi Dawn,
Open iTunes and select preferences under the itunes menu. under the General tab look for import settings. Select AAC as the encoder and 128kbs. then open your main iTunes window and select some music you want to convert, then look under the advanced menu and one of the options should say create AAC version. Andor if your sending music to an iphone or iPod there is anoption in the device preferences that will do the same thing.

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?

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:

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,

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.

What does convert higher bit rates songs to 128 kbps mean

Some people, myself included, import their music from original audio CDs. When doing so I choose to import using Apple Lossless format so as to keep the full original quality of the audio CDs (this is after all why it is called Apple Lossless format in that you are not losing any quality).
The drawback of doing this is that the music files take a lot more disk space than a lossy format like MP3 or AAC. This is these days not a problem on a computer as hard disk space is now cheap an plentiful but it can be a problem on a flash memory based music player like the iPod Shuffle, iPod Nano, iPod Touch, or iPhone as these have far less capacity.
Therefore Apple now let you turn on this option to automatically convert from Apple Lossless to AAC when syncing to one of these music players. As a result on your computer the music is still kept in the full lossless high quality format, but is converted and transferred as a much smaller but slightly lower quality for use on these music players. As with an iPod you are not listening in a quiet room with high quality speakers you will not really notice the difference in quality.

Loss of bitrate when converting from 256 kbps to 128 kbps

Hi everyone,
I had over 800 MP3s of various bitrates which I converted to 256 kbps AAC format in iTunes, in order to standardise them all, then deleting the originals. However, I was then told by a friend that if I simply reconverted the new ones to 128 kbps but still saving them in AAC format, I would save on half the disk drive space. Since memory is at a premium on my computer, I did just that but the results in iTunes show that the songs have since turned out in various different bitrates again, ranging from 99 kbps to 103, 105, 107, 123 etc. The settings in Preferences are as I left them, AAC Encoder with High Quality (128 kbps). I realise that this is not such a big issue in terms of listening and playback but I am curious as to why iTunes has decided to dictate the individual bitrate for each song despite my settings. Any comments or feedback would be much appreciated, thanks!

Greg, I don't think you will notice a big deal of a difference.

If I convert the songs on my iPhone to 128 kbps, will the play counts still sync with what's on my computer?

If I convert the songs on my iPhone to 128 kbps, will the play counts still sync with what's on my computer? I have a lot of songs on my iPhone which are at the 256 kbps bitrate, and if I take them down to 128 kbps on my iPhone, I'll be able to fit a lot more music on my iPhone. But...I really would like to keep the play counts between my iPhone and my Mac in sync. Will that still happen if I switch, or will there be an issue?

Anybody?

"Convert higher bit rate songs to 128 kbps AAC" doesn't allow full fill

Hi,
The 128 kbps option does indeed shrink the size of the songs on my 3GS iPhone when using iTunes 9.1, but it won't let me fill it up it and complains that I have more music than can fit. I have been playing with this and for test purposes have 3 playlists. I am able to sync the first 2 and have >15GB free. I add the 3rd playlist which has only 8 GB in it and the sync fails saying that there isn't enough room. I have tried rebooting the iPhone and the Mac Pro both of which are on the latest version/service pack of their respective OS's.
The only thing that I might have that is non-standard, is that some reasonable portion of my music is encoded at 320 kbps rather than 256 kbps.
Anyone have any idea what is happening?
--Jonathan

Try redownloading iTunes from www.apple.com/itunes. It will show that you are still downloading/installing version 9.1.1 but it is build 12, instead of buill 11. This new build wasn't in Software Update but version 9.1.1 (11) had issues with this conversion to 128 kbps. Version 9.1.1 (12) fixes it.

Converting all my music to AAC 128 KBPS, Will there be a difference?

Will there be a major difference between anything higher then 128 Kbps?
I don't notice a thing. And plus I don't really pay attention to sound quality.

I can hear the difference between 128 and 320. that's one of the reason I never bought music online at that bit rate. other than 4 songs I got from Amazon, all my music has been ripped from my cd's at 320. Lossless doesn't provide any tangible benefit for me, but there are some that require lossless to "float their boat".
