iTunes 11.1.2 playback distortion

I know I never had the equaliser on at all, But since people were suggesting having a fiddle in the settings I noticed it was on (With the tick box) Unticked it and it is back to normal, So have a go at Just Unticking the On box and see if that helps?

updated to OS Mavricks and now my music sounds canny and distorted when playing through Bose companion 5 speakers or internal speakers.. seams to play ok through Airplay on Denon Receiver..

Tried the "Turn off and then back on Equalizer" while the music is playing and it seams to work for one song at a time..

Apple Help.. Please fix, I need my music 😟

PS iTunes radio seams to be working just fine no matter the speakers or device selected..

Same problem here. No distortion using VLC or Youtube, only iTunes. Not sure what caused it, I updated to Mavericks and iTunes 11.1.2 at the same time. Changing EQ settings to flat removes the distortion, but I'd like something more than a quick fix.

I am having the same issue. Sound is fine using other media players. Sound is also clear using Spotify, pandora and other online streaming services. Itunes sounds like the amp has been turned all the way up and distorting all sound.

I have not upgraded to maverick's, but this began happening when I upgraded to 11.1.2

Here is how to reproduce the problem:

If an EQ preset is chosen (and activated), every song will be played with a distorted sound. Disabling the EQ fixes the problem (and then enabling it again will play correctly, with the EQ preset correctly applied).

The fix is temporary though, because every time iTunes plays a new song, the distortion comes back again.

Manually disabling and re-enabling the EQ every time a song is played is a pain (it makes using iTunes with EQ for a party completely impossible) ! Please fix this issue soon !

(I'm using Snow Leopard, and iTunes 11.1.2 and this problem just occured since I upgraded iTunes)

Same problem here. iTunes 11.1.2 is the problem: thought mp3s and aac-files were the problem: they sound so muddy and strange to me all at once. But playing back same files from other software does not have these issues.

Come on apple: is this a OS meant for audio and video pros? This is much worse than all the glitches in iBook and so on.

So as of late, their reputation continues to tarnish. Same problem with 11.1.2. My kneejerk was to spend a lot of time trying to fix my machine, preferences, trashing files, rebootings, PRAM, etc, etc. etc. Should have looked on forums first and figures Apple broke something.

Thank you very much, this helped me a lot, I have been experiencing the same problem and after reading your advice my library is now back to normal, thanks again!

Same thing happened with me. Selecting your entire library, then Get Info>Options>Equalization and seting it to flat seemed to fix things. Pretty strange though.

Thank you, thank you, thank you, this helped a lot, no more muffled noises, do this and you will get perfect sound!!

I haven't tested yet, but it seems that there is a fix (not a workaround like disabling the EQ): downloading and reinstalling iTunes...

I am also experiencing distortion of low end frequencies (sounds just like a blown woofer) on audio playback from iTunes. I have been unable to rectify the problem by deleting plist entries or reinstalling. I am currently running mavericks 10.9, iTunes 11.1.3 on a 2011 Macbook Pro 15". My audio interface is an Apogee Duet, but no other applications exhibit the audio symptoms, only iTunes. So I don't think the Duet or its drivers are at fault (though it could be a factor in my case).

Anyone else exhibiting fluttering of low end frequency distortion with iTunes please chime in. We need to build volume on this to get a resolution.

Thanks!

It might be something more than just what's happening with iTunes. I'm playing Google Music audio and I get the same exact distortion. Like a wavy vinyl record being played. I think it has something to do with Mavericks. I don't get the distortion in Google Music playing from Windows and Android machines on the same network. It's just my Mavericks on a MacBook Pro e2011.

I have the same problem. Is there a fix yet? I adjusted Equalizer setting to "Flat" but distortion/reverb/echo still occurring. I am so not good with this stuff and just want to play my Christmas music.

Please HELP!!!!

I just fixed the problem! Window-> Equalizer. Someone set all the frequencies to max on the equalizer. I changed it to "flat" setting (or by turning it off) solved the problem.

I thought I was going insane and decided to do a search and saw people dealing with the same issue as me. I can listen to music on my 4th generation iPod, iPhone 4s and Amazon cloud player with no problem. The Amazon Clould player is playing it without distortion from the local iTunes library file and from Amazon's clould file. When I turn it up on hear pops an clicks on silent parts, just like an old album. Something has been broken. I selected every file and in the info set the eq to flat and that seems to have helped but I was going mad before.
