Sound check - apple tv

My music library is at iCloud.
When I'm listening my music on apple tv, the volume is often diferent from one song to another.
In iTunes we have "sound Check" that automatically adjusts song playback volume to the same level.
Is possible to do the same when listening my icloud music library on apple tv ?

Yes, there is a sound check option under the audio settings.

Bug in iTunes 9.0 Sound Check ?

In iTunes 8.x when you add a new song to iTunes (with Sound Check enabled)
iTunes adjusts or adds the "normalization information" ID3 tag for the song.
iTunes 9.0 doesn't do this anymore.
Is this a bug in iTunes 9.0.0.70 ?
Ps: Programs like iVolume rely on this info.
Edit: 10/09 16:09

See this -> Don’t Panic
"Yesterday (09/09/09, by the way) Apple released iTunes 9. Unfortunately it has a nasty bug that prevents iVolume from analyzing songs that have been imported from a file. All other songs – that is purchased, ripped or converted songs – will still be processed fine by iVolume.
We put highest priority on this issue. All other projects have been interrupted in order to restore full compatibility with iTunes 9 as soon as possible. We already found a solution and are currently busy implementing it. Things look good so far.
So please be patient, a new version of iVolume will be released very soon"

Sound check / normalization problem with matched versus uploaded tracks

I am finding that matched tracks are playing MUCH louder than uploaded tracks on my iPod. Before I started the match process, my library was normalized to an 89 dB reference level, which USED to be the audio engineering standard for recordings. The AAC tracks that Apple has matched my tracks with seem to be as much as 10 dB above this -- the difference is painful. To make matters worse, iTunes Match usually only matches portions of albums, so some of the tracks (the uploaded ones) are playing back at a reference of 89dB while the matched tracks are playing back at whatever Apple uses (my guess is @98-100 dB). My understanding of the MP3 file format is that there is no benefit to ripping to a 100 dB level. It is not like the old days of analogue tape where you could improve the signal-to-noise-ratio by recording slightly 'hot.' In an MP3 file, there is normalization information stored in the file header. I do not know about AAC files.
I have turned 'sound check' on on my iPod, but it doesn't seem to make a difference. Has anyone found a way to fix this issue short of renormalizing the entire library and then re-uploading verything to the Match service? Needless to say, the original process of getting everything I owned to 89 dB was tedious in the first place and I don't want to have to redo that. If I do need to redo everyhting, does anyone know what reference level Apple uses for its matched files?

@ roebeet. Thanks for telling me that 'Sound Check' does not work in iOS 5. That is what I had found, but it's good to know it's not just me. I talked to an Apple tech support guy and he seemed to know nothing about this. He had me hard reset my iPod and then wrote it up. He was quite nice about it, and suggested I send a recomendation email to Apple.
I downloaded a half dozen of Apple's matched AAC tracks from the iCloud and ran a volume check on them, and they seem to be using levels in the upper 90 dB range, so my guess that their tracks were a full 10 dB louder than my 89 dB tracks was confirmed. What I've done to solve this is to remove all my uploaded MP3 tracks from the iCloud and from iTunes, renormalize them to 98 dB instead of 89 dB, then reimport them into iTunes and then reupload them to the iCloud. It seems to be working so far.
You are right about some of Apple's stuff being clipped. You don't need Audacity, either: digital clipping sounds so very very ugly. The Apple 256 kbs AAC version of 'Babe I'm Gonna Leave You' from Led Zepplin I is clipped. There is no excuse for this. It makes me wonder how to alter a file so that it won't be matched: my MP3 version of the song is fine.
Thanks again for your help.

Is iTunes "Sound Check" better than five years ago?

I got into iTunes (briefly) about five years ago. I got all excited about mixed playlists and what-all ... but I burned out quickly because the Sound Check feature that would regulate the volumes from different CDs was mostly worthless. Most songs averaged out, but that one track in ten would still sneak in there, too loud or too soft, and ruin the listening vibe in the house.
I ditched iTunes and went back to my CD player.
Now I'd like to get back into iTunes again and I'm wondering if Sound Check ever had any significant improvements in the last five years? Did Apple finally perfect it?
Do we finally have mix playlists that play consistently, like one properly re-mastered compilation CD? Or are occasional tracks still showing up too loud or too soft?

Thanks for the replies, Wolf and Sanjampet.
Yep, both of you are spot on correct about some of the dynamics that affect Sound Check. The only thing I know is that, five years ago, I didn't like it. I also remember not really being able to make manual adjustments work for me because I have music playing constantly and jumping up and running over to the Mac while an offending song is on my mind got mighty inconvenient. That's why I stuck with my CD player. ...
I think you answered my question for me. No, Sound Check is no different than it was five years ago.
Not quite what I said. I certainly expect it has improved over 5 years, I can only tell you it will never be perfect. And that is relevant because of your expectations.
The fact is, CD players do not have SoundCheck at all. But when your CD mismatches song volumes, that does not "offend your ears". And yet, oddly, iTunes does. Listening sequentially to a CD you already know, you are accustomed to those particular mismatches, so they "sound right" to you. What I'm speaking of here is cognitive bias, which is human and normal, and the thing to do is simply be aware it's there.
I too have tried playlists and was not impressed. I remember when the level adjustment (in Song Properties) came out and thought "about time". And I've never spent the time to actually try playlists again. But I did not abandon iTunes entirely simply because one of its features "is not for me", i.e. sucked. Digital playback is still the Best Jukebox Ever, with instant and searchable access to my music. CDs are in every way inferior.*
It sounds like you jumped into digital playback with both feet, found some of its features were not ready for prime time, and jumped back out. I would suggest easing back in with one foot, remembering that setup is a one-time task and it's pure profit from there.
* purposefully ignoring the question of musical fidelity, some believe compression is bad, others believe digital is bad. Not this thread.

IOS 5 Sound Quality and Sound Check issues

So since upgrading my iPod to iOS 5 the sound quality of my music has deteriorated massively and sound check no longer works as it should.
Tracks sound crackly and audio volume will remain balanced for a few tracks when sound check is on, then all of a sudden become completely unbalanced and all over the place. My iPod is only just about useable, it's a bit of a disaster that its main feature doesn't work as it should.
Everything else in my iOS5 works as it should.
Any help would be greatly appreciated.
Richard.

Since I bought iPhone4 and listened my songs with "Ipod app" and external speakears I was amazed how brilliant, sharp, intense, clear, perfect bass, perfect trebble the sound was, there was no distortions or saturations ever... The sound quality was just PERFECT with the equalization OFF!!! Not remember if I had SoundCheck ON before but now it doesn't make any difference. I installed iOS 5 over 4.3.1 or so and now sound is just more like noise compared to iOS 4, I have selected all presets or equalizations but ALL are poor, maybe some presets work better with some songs but still they are poor.... Songs did not have clarity!! The volume force was like degraded, now I have to set higher volume to produce same force than before with less volume... iOS 5 max volume (100%) is like iOS 4.2.1 85-90% of volume. Difference is that iOS 5 maximum volume starts slightly to distort or saturate audio quality... before with iOS 4 sound quality was Crystal Clear even with max volume!!! In short SOUND QUALITY is DEGRADED... or perhaps I'm a very critical and nonconformist guy in terms of audio quality... this kind of degradation is quite notorious when one loves music!! or is there some other configuration I'm missing here??
Totally agree with Richard!!
At first I thought it was a problem with my phone... I used to believe iOS 5 was engineered for new iPhone 4S hardware and since it is shipped with dual-core processor, I thought my phone was short in resources!!!
Why max volume is lower in intensity???
Why equalization with the EQ Off changed?? All my songs were stored on iTunes, they must have same sound quality properties as they were when first ripped..
I hope Apple enginneers did not sacrifice volume output force in favor of saving some battery, because normally we charge battery when listening music at home with our personal speakers equipment.
I would like to understand the reasons why the new "Music App" was "changed", and why these changes have to go backwards!! That is sad... because for iPhone or iPod lovers music was always important.
thanks

Surround sound check

Is there a surround sound check for Apple TV?   (center, left, right, left surround, right surround, subwoofer)
I was at a friend's house a month ago watching horror musicals and all the singing was coming from the rear speakers.   On other occasions I've heard dialog coming from the left and right and not the center speaker.   I don't own an Apple TV so I don't know how to advise him in this matter.
Second question: What's a polite way for a guest to tell a host that their sound setup is wrong and they need to fix it?   This has been going on for years and my lip is bleeding. (See: http://www.usingenglish.com/reference/idioms/bite+your+lip.html)

Here's a pretty good surround-sound test file:

Take it to your friend. His setup is mis-wired.

Sound Check doesn't work

I just switched from Mini to Nano and now when I playback songs the volume is all over the board. One song is on 5 one is on 10 and back and forth... I have tried several times to check and re-check the Sound Check feature. Am I doing someting wrong? If the song volume was close to each other it would be fine but it is WAY OFF. Thanks for the help.

You need to check that option at iTunes as well. Did you remember to do that?
If it doesn't work, try send Apple feedback about your iPod. Be polite and clear and if this is a general problem they will correct it on the next software updater.
Hope this helps

"Disable" Sound Check

There has been much discussion about the pros and cons of Sound Check, and some excellent details are provided about how it works and how difficult a process it is to standardize volume. Generally, I'm happy with the feature with one exception: live concerts, especially with songs that segue, like a Dead or Zappa concert. If I want to listen to the contiguous show, sometimes there are significant swings in volume between tracks. Yes, joining tracks is one option, but that creates very long "songs." I could also go track by track and manually set each song's volume to some standard, but my ear ain't that good. So my questions:
(1) After tracks have been imported and Sound Checked, is there a way to reset a certain group of songs to the original, non-varying, un-Sound Checked volume level?
(2) If not, can I re-import the concerts and somehow maintain the consistent volume level for the tracks that make up each show? Would I have to turn off Sound Check in perpetuity to do this?
Thanks for any suggestions

Sound Check works well on an iPod when listening through the headphones. Works on all iPods, as far as I know.
Some iPods have their 'Line Out' audio (Dock Connector) affected by Sound Check, others do not.
If may be iPod 'Generational' differences &/or Firmware differences - I do not know. The only way to determine if the Sound Check feature works via the Dock is to perform some simple tests (if you have the appropriate connections).
I determined that my 2Gen iPod mini with Firmware v1.3 does not pass Sound Checked audio via the Dock. Makes it more work to manually adjust the volume in my car (via a Direct Interface) or my home speakers.

Sound check (volume leveling) not working newest ipod

Dear Apple community,
Thank you for your help with this problem.
I am extremely disappointed with my new iPod. I have been using iPods for 15 years. Many years ago I solved the problem with volume leveling by using a fantastic program called iVolume. I have over 25,000 songs (collected over 20 years) in my music library and I have never had a problem with the different sound levels when I play them back through my various Ipods and Iphones over the years.
Unfortunately when I recently purchased the latest generation of iPod I quickly found out that volume leveling no longer works. The discrepancy in the sound playback is most apparent when I use the bluetooth connection but is also present even when I play through the audio jack. I have tried turning sound check on and off, and have done a complete reboot of my ipod, and have not seen any difference.
Any help with this problem would be most appreciated.
Sincerely,
David Rojer

My iVolume is version 3.7.4.
My Ipod is model PD478LL with version 1.0.3 Mac.

Nevermind I worked it out. Just had to restart iTunes. Classic IT Crowd: "Have you tried turning off and on again?". Lol.

The Great Sound Check Dilemma

This may be more of an iTunes question, but the problem is most noticeable when using the iPod with the Hi-Fi.
I have a mixture of imported and purchased (from iTunes Store) music. Sound Check does a reasonable job of equalizing the volume between songs, but there are still very noticeable differences. I have read about the program "iVolume" and may give it a try, hoping it will even things out a little more.
The dilemma though, is that some of the mismatched volumes are between songs purchased from Apple. Sound Check has done the best it can, and iVolume apparently cannot modify these "Protected AAC" files!
Does anyone know of any other options?
Thanks,
JimT

There's no other option for the iTunes purchases because they are DRM protected and cannot be altered.
However, iVolume's default volume setting (91 dB/92 dB) is pretty much near to volume used by many of the songs in iTunes.
I've used it for a long time now, and whilst there is still some volume difference between iTunes songs and others, it's still very effective.
You can test it out for free.

Sound Check feature

I used the sound check feature in iPod that automatically adjusts song playback volume to the same level to load songs on to my ipod mini. The sound quality seems to be very poor i.e. crackling and distortion with bass and higher end tones. I'm just wondering if the Soundcheck feature is the culprit or if the iPod mini just has poor sound quality. I encoded at ACC 192 kbs, VBR. I tried encoding in LAME M3 and got the same results. I'd really appreciate any help on this as I'm thinking of returning my ipod if the sound is normally this poor. Thanks again.
Ian

Yeah...the problem seems to sort of go away when I turn the EQ off as well but that's pretty lame if that's the only solution. Is there anyway to get better sound quality other than going with apple lossless or a really high bitrate? Any help would again be greatly appreciated.
Thanks,
Ian

DTS CDs and Sound Check

I have successfully imported all of my DTS audio CDs into iTunes using Apple Lossless format. I use the digital outputs of my computer/AppleTV/Airport Express to play back the multichannel sound from these CDs into my audio system (which has DTS decoding built in.) Everything sounds groovy.
This setup is, of course, completely incompatible with any of the audio processing features of iTunes, such as Sound Check, Crossfade Playback, etc. because these features alter the bitstream thus causing the DTS decoder to fail, resulting in white noise.
I definitely want to use the Sound Check feature on my non-DTS tracks. Is there a way, on a per track basis, that I can tell iTunes "Don't use any audio processing features on this track"? I would then apply this option to just my DTS tracks. If no such feature exists, how can I petition Apple to add such a feature, say, in the Get Info area for each track?

Hello,
I have to admit I've never used it but found this Macworld article a very useful explanation:
http://www.macworld.com/article/44344/2005/04/soundcheckyou.html
iVolume which is linked to from the MW article should check all your files again and put the adjusted volume in the ID3 info.
HTH.

Sound Check Audio Quality

Hi,
I have many CD's ripped in apple lossless encoding stored on my Apple TV. I use the optical output for optimum audio quality. Does anyone know how Sound Check actually works and does it affect the sound quality.
Thanks,
Paul.

No idea how it works, but I assume it reduces dynamic range.
Whatever it does it sounds awful.

Sound check weirdness

If I have sound check on in iTunes and also on Apple TV 2, it seems to cancel each other out. Song volume is all over the place. Normalize is completely shot. So I turned off the option on ATV2 and left it on iTunes and the music volume is back to nearly normalize levels. Well as close as iTunes is capable of doing. I have ATV 2 via HDMI to my Onkyo receiver. Has anyone experienced this? ATV has been updated to latest firmware release.

I tried turning iron and off. Seems to help but still a bit off on some songs. I guess I'll manually adjust those songs that are obviously way off.

Enable Sound Check not working on Shuffle

On an iPod Shuffle (4th Gen v 1.0.1) and through iTunes (v 11.0.2) my setting of “Enable Sound Check” isn’t working and, of course, I wish it was. Is there someplace else I should be looking, as I’m only aware that things can be set through iTunes?

I got the same problem....
