    I just uninstalled itunes and quicktime and re-installed it and all my music was there.. I obviously didn't uninstall it propelly, I went to the control panel and went 'add/remove programs'. The quality is still muffled.

    I've also discovered this is not an iTunes 10 problem specifically, I've seen in past threads that users upgrading from 6 to 7, 7 to 8, & 8 to 9 all experienced muffled audio quality. There's something fundamentally wrong here..

    ok wow i just used quicktime to play the same file, and the quality IS 100 TIMES BETTER THEN IN iTunes!!!!!!!!

    Oh, so you're running Windows? I'm on Mac, odd we have the same issue.

    Sound quality is horrible on my MacbookPro after the Itunes 10 upgrade.
    First I thought something went wrong with the speakers.. and a quick search brought me to this discussion.
    I am looking to downgrade to Itunes 9.

    BTW, this is on Mac OS .. I guess its not just windows Itunes 10 version but also Mac version that got screwed up.

    I have spent the past 4 days researching this problem and have found NO solution! My sound check/ sound enhancer etc. are all off. The same files are sounding crisper and clearer in quicktime/vlc/WMP. This is clearly not an iTunes 10 specific issue as upgraders from all past upgrades have experienced this in minority. There is nothing wrong with my speakers/sound card. APPLE PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!

    Same here: MacbookPro and iMac (Snow Leopard 10.6.4). I just upgraded both computers to iTunes 10 and sound quality is much much worse and it's even much MUCH worse when you import a new file into your iTunes Library. Just do it, with one file that you already have in iTunes. Re-import it wiht a different name and compare both songs: they seem from different historical periods. I think I'm going to downgrade to iTunes 9. Maybe Apple was so much worried about changing the new iTunes logo and including Ping that they missed something at Cupertino.

    Yes. Same problem on my late 2009 iMac. I justed started a thread in the Mac section on this, as it appears the problem is not just on the Windows side.

    I can also confirm that the very same mp3 file sounds great in VLC, but tinny & quiet in iTunes 10. This is on a MacPro with OSX 10.6.4.
  • ParanoidAndroid2010 Level 1 (0 points)
    yep its 100% true. I tested iTunes 10 on my friend's PC and the same issue. Since I have received NO SOLUTION I downgraded back to iTunes 9. WHAT A RELIEF!! Everything sounds normal again!

    Same issue here! I didn't play any music for a few days after upgrading until yesterday and wow! Awful! I'm glad I'm not the only one. I started playing with the system sound settings and thinking it was my system. How could Apple be so sloppy? The sound quality sounds muted and distorted like some old LP or decayed 8 track. I'm an amatuer musician and the moment I played the first song on iTunes 10, my ears bled from disorientation and disappointment. I'm downgrading back to iTunes 9.2.1. Here are instructions how:

    same here. Super bad audio quality after upgrading to itunes 10. Going to downgrade as earlier suggested. This is lame. You would think iTunes would have been tested a bit more before Apple released this. IMHO, iTunes 10 is a step backwards. Fingers crossed theres either a fix or update released soon.
  • pickyjohn Level 1 (0 points)
    Had the same problem, thought Adobe player update caused it but no. Eventually restored from a Ghost backup made several months ago. Now running iTunes 9.1.0 and afraid to do any updating.
    Apple does this periodically so years ago I started downloading all versions separately, rather than auto-update from within iTunes, and SAVE them in case I need to go backwards. Unfortunately Apple didn't have any issues for several versions and I became lax.
    Doesn't Apple know how much anguish and work they cause by screwing up the sound quality? On XP WMP does not stand up to iTunes on sound quality - but on Windows 7 WMP sounds just as good. Wake up Apple!

    I wonder if this is what I am experiencing. I just got a refurbished iMac i7 and had the data transferred. The computer obviously has iTunes 10 preinstalled. I was listening to music for the first time last night and it sounded awful -- very tinny, etc. and I have very good speakers hooked up. I thought there was something wrong with the output jack, but maybe it's just iTunes?

    I'm also suffering terrible sound quality in iTunes 10, though for me the problem actually started in iTunes 9...

    There is a nasty distortion present in the audio that is not there if I play the same file in Quicktime. The problem becomes much worse if I stream audio out to my Airport Express (distortion is on the computer side doing the streaming, not necessarily at the Airport Express end).

    I have submitted bug reports for both iTunes 9 and iTunes 10.

    This problem is very reproducible and even happens if I use internal Mac audio with headphones attached.
