Import CD at AAC 192 Kbps, burn some songs to new CD = inferior quality

I recently burned some songs from iTunes to a CD for my wife to listen to in the kitchen.
When I went in, the audio quality was definitely much poorer than the original CD.
So, I did some testing.
Even at 192 Kbps import of the CD song into iTunes, the output sounds much poorer.
So I re-imported the AIFF file directly from the CD and compared waveforms. They are Very different.
Are CD burns intentionally crippled by iTunes?

Well guys, I have to say I think it may be Red Herring time...
I re-imported a new test track (Joe Farrell -" Outback" - has lots of dynamic range) using Apple Lossless. I then burned a CD -
Outback AAC 192kbps
Outback Lossless
Then I re-imported the CD (both tracks) as Lossless and compared them in QT player (synchronized playing, looped, so I could switch between them during playback).
I had five files sync'ed up in QT player:
1) The original AIFF file from the original Joe Farrell CD
2) The iTunes library version of the 192k original import
3) The iTunes library version of the Lossless original import
4) The iTunes-burned CD re-imported version of the 192k original import
5) The iTunes-burned CD re-imported version of the Lossless original import
Listening with my Shure e3 in-ear phones, I could not hear any differences between any of them.
Tomorrow I will compare the waveforms and spectra...
(BTW- The original disc I imported at 192k and burned still sounds bad, but the problem is probably not iTunes. Could be a bad CD-R, I guess)

  • Why can't I burn some songs

    I have a MAC OSX version 10.6.8.  It let's me burn some cd's but states "my computer is not authorized" to burn others even though I have burned the same songs in the past.  How do I correct that.  I-tunes states that my computer is "AUTHORIZED."

  • When i add some songs they dont add and another thing

    when i add some songs the space amount will sometimes jump from eg. 12.45 to 12.51 and the file size is only 4mb. than after that it will jump back down to 12.46 and continue like nothing has happened. than i go to listen to some songs old/new on itunes or my ipod and on itunes it shows ! which i know means its gone but i dont know how and on the ipod it goes on it but skips. any help thanks

    If I understand you correctly, iTunes is not transferring songs to your iPod. Before you sync again, make sure that the selections you want transferred are selected (by clicking the box next to each selection from your library in iTunes). Also try this, when your ipod is connected, click it under devices and select 'Music'. Then make sure 'Sync Music' and 'All Songs and Playlists' are selected. Good luck

  • Cannot Change Custom Import Settings For AAC's

    Last night I changed the custom import settings from 192 kbps to 160 kbps for a particular mp3 album I wanted to convert with that bitrate. I tried to change the custom settings back to 192 kbps (the bitrate most of my mp3's & wma's are in). For some reason, the window that came up many times before refuses to pop up now. I tried the custom settings for mp3's and that window still pops up. Anyway, I tried a repair and nothing happened. I uninstalled iTunes, Quicktime, Bonjour, and Apple Software Updates, deleted there corresponding folders in C:/Program Files and then restarted the computer. I downloaded the iTunes 9 installer through the iTunes website and proceeded to reinstall iTunes. Still, the problem exists. I'm not sure what else to do? The only other thing I can think of is to do the same except install iTunes 8 instead and then search for updates and reinstall iTunes 9 that way. Would anyone know of any other method on solving my problem? Any help would be greatly appreciated, thanks!

    glenn,
    I have the same problem and it is driving me crazy. If you find a solution please email me at [email protected]
    thanks and good luck

  • Shuffle 2G not allowing some songs to be imported

    I just got my iPod Shuffle 2G this evening and while I was selecting songs to be on my shuffle I discovered that some songs were not importing. I drag a song to the shuffle in iTunes and it will not allow me to drop it. What is the issue? I've looked at some of the information of the songs not importing and some of them have lower bit rates such as 95, 127, and 191. What gives?
    Shuffle 2G   Mac OS X (10.4.8)  

    In doing some more investigating I've discovered MANY songs that simply will not import to the shuffle. Most of them have odd bit rates. I would be incredibly surprised if this has not been discussed before.
    Does the 2G Shuffle not allow songs with "unusual" bit rates to be imported? I made a playlist that is significantly smaller than what the Shuffle can hold. There are 183 songs in the playlist and only 158 songs are on the Shuffle.
    What would cause this? I converted some of the songs to AAC and then they imported correctly. Is this something I'm required to do on all my songs I want on my shuffle but will not import?

  • Changing Import Settings in AAC Encoder, Custom

    I changed my import settings to AAC Encoder, Custom, and set the bit rate to 160 kbps from the menu of options.  Now that it is set, I cannot change it.  It no longer shows a menu of bit options.  How can I change my Custom settings again?

    Note, I use iTunes 7.5.  With this version I:
    iTunes > Preferences > Advanced > Importing
    Import Using: AAC Encoder
    Settings: Custom
    --> New window
    Stereo bitrate: [a selection from from 16 to 320]

  • Why doesn't a Wav file import convert to AAC?

    Hello,
    I tried the "add file to library" and the "import" menu options to add a wav file to itunes. For both methods, I found that although the file gets added to my library, its not in AAC format which is my default import format in my preferences.
    I can tell its not in AAC format by the 1400kbps rate which is normal CDA quality and not compressed. Also the file size is huge.
    Any ideas on how to import wav files from my hard drive to itunes library on same hard drive?
    Thanks for all help.

    Once you have added the WAV file to your library, select it. In the upper-right corner of your iTunes window, where it normally says Burn Disk, it should say Convert (or something to that effect).
    Clicking the icon will convert the file to the format and bitrate you have set in iTunes preferences.
    Once you convert the file, you can delete the WAV file from iTunes if you wish.

  • Do I need to convert my AAC files before burning an audio CD?

    I import all my music CDs into iTunes 9 as AAC. When I want to burn a playlist onto a CD as an audio CD, do I have to manually convert my the file into an AIFF format before burning a CD? I think I read that regular CD players cannot play songs that are in AAC format and must be in AIFF format. The CD will be played on a regular car CD player.

    Do I need to convert my AAC files before burning an audio CD?
    No.
    Simply selecting *Audio CD* in the Burn window is all you need to do.

  • I recently tried to burn some photos to a disc.  It did not work, but then I ended up with a .fpbf folder on my desktop.  Can't trash it, and when trying to burn again, I get this "... can't be burned because the original items can't be found". Help???

    I recently tried to burn some photos on a CD. For some reason, It did not work.  Now I have a .fpbf folder on my desktop. I can't seem to get rid of it.  I tried dragging it to the trash, but then I get a box asking my to type my password it, so Finder can make the changes.  Doing so, does nothing at all.  And when I try to burn another CD from the same .fpbf file, I get a the following message: "There are 35 items that can’t be burned because the original items can’t be found. Skip the items and continue burning?".   When I skip and continue burning, nothing shows up on the CD.  In the meantime, the .fpbf folder is still in my desktop.  I tried changing the aliases on each pic, but it still doesn't work.  Any ideas of how I can remove this folder from my desktop?
    Thank you.

    Beavis2084,
    Thank you for your detailed explanation but something is seriously wrong with my computer. Although the method you have described is very similar to the one I tried in step 2 from my second post, I have since "done things" which may have complicated matters—or suggests that my computer has a more serious problem.
    Here's what I did:
    1). Installed Onyx and discovered that I had a .plist file (com.apple.iphotomosaic.plist) that was causing a Syntax error: "Conversion of data failed. The file is not UTF-8, or in the encoding specified in XML header, if XML." After doing some research online, I was given the understanding that downloading the iLife update 9.0.3 (I installed the more recent version, 9.0.4) would solve this problem because it would also fix some system issues. So, I downloaded it...and when it didn't solve the problem, I decided to just deleted that .plist file.
    2). I read your knew post and decided to follow your directions, even though I realized they were basically the same steps I followed in the 2nd method I mentioned earlier. I say "basically" because, for some reason, after inserting a blank disc, my computer does not open the disc in the Finder. Instead, it places the blank disc's image on the Desktop, even though the Finder's Preferences and the System's Preferences are set to have it open in the Finder—nothing should be on my Desktop! (Note: When transferring the items (all folders) I want to burn to the blank disc, I did not use the Option-Click-Drag method as before, I used the Click-Drag method, which created the curved arrow in the lower left corner of each item.)
    Now, for the result of "method 2," the method we basically have in common, the computer goes through the burn stage but, in the verify stage, tells me that it is unable to verify the disk, suggests that my DVD may be unreliable and that I should try another disc, and then tells me about some "fork" (?) error (-43).
    I don't know what to do anymore...

  • I am trying to burn some cds from my playlist on itunes, but my playlist shows many of my songs in light print and says that it will not burn because it is not a file, these are all songs I have purchased quite a while ago, how do i get them to files?

    If they were songs you purchased from itunes, try redownloading them from your purchases...
    if that doednt work, make sure the optuon to copy files to itunes media folder is checked in settings, then find and download from the net. and re-add them to your library

  • I can import some songs from another computer but not others.  All the songs were purchased with the same apple id. Message says "...check connection to network..." Any ideas as to what could be causing this problem?

    Using home share, I can import some songs from my son's  computer but not others.  All the songs were purchased with the same apple id.  Err msg:"There was a problem downloading ... You do not have enouggh access privileges for this operation. Please check that the connection to the network is active and try again."  The network appears to be fine .  I can import other songs from his library.  The same songs cause me a problem each time I try.  My husband had no trouble importing the same songs I have trouble with. I get the same error message if I try to import the same songs from my husbands computer as well.  "Command I" appears to show the same protections on both the songs I can import & the ones I cannot.  My husband and son are both running OS 10.6, while I am running 10.7.  I think I had this problem even before I upgraded, but I am not certain.

    Welcome to Apple Discussions..
    My first suggestion is to Repair Disk. Here's how:
    Insert Installer disk and Restart, holding down the "C" key.
    Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    (Check S.M.A.R.T Status of HDD at the bottom of right panel, and report)
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
    Please post back and let me know how that goes.
    Here are a few links that may help you to identify the issues:

  • When I import my CDs to ITunes it splits some of them into 2 or 3 separate albums. Is there a way I can combine them into one?

    When I imported my CDs into ITunes it split some of them into 2 or 3 separate albums. Is there a way to recombine them back into one album?

    If your CD has tracks with different artists, then you need to identify it as a 'compilation' CD. Select all of the tracks in the CD, then 'get info' (control-I), and go to 'Options'. Select 'yes' for 'Part of a compilation'. That should fix the problem.

  • Imported photos, transferred some photos to new album, deleted originals, ones in album are gone. How do I retreive them?

    Imported photos, transferred some photos to new album, deleted originals, ones in album are gone. How do I retreive them?

    Check the iPhoto trash - if they are there select them and right click and restore to library
    If they are not there then they are gone
    You really should take the time to learn how to use iPhoto - photos exist only in one place  - in your events - albums, keepsakes, etc are just pointers to the actual photos in the event - deleting from an album does just that - deletes from the album - deleting from an event removes the photo and therefore all albums, keepsakes, etc
    watch the videos as a starter - iPhoto help menu ==> iPhoto help and watch the video
    also more details (for a previous version so some menu items are in different places but the concept is the same) - and it would be a worthwhile investment of time to take the iphoto tutorials - http://www.apple.com/findouthow/photos/ - they are very helpful and will save you a lot of time and frustration.

    You could Zip them into an archive. They compress somewhat. Or Stuffit will allow you to segment an archive into 4.7 GB segments...

    I downloaded and installed Photoshop Elements & Premiere Elements.  I then launched Photoshop Elements Organizer and imported approx. 28,000 photos (including some videos).  A window opened indicating that many of the photos had tags, and asking if I wanted to add the tags.  I said yes, and the process began.  When it reached 60% a window opened indicating that "Elements 13 Organizer has stopped working", with the only option being to "Close program."
    I've since tried to open organizer several times, but it goes immediately to "Elements 13 Organizer has stopped working".  I was able to open Editor, and tried opening Organizer from Editor, but encountered the same problem.
    FYI, I have an open case (#0214505556), but have not received the help I need.

    This issue is with respect to Elements 13.
