    Hi Thebosspower

               Apologies for the delay in response I had to take a break from testing as it was driving me nuts. Ok here's what I've found out so far plus a little explanation of "why's and methods"

    First of all why set the volume in itunes options at 100% ok most amplifier devices have a volume control but what manufacturers don't tell you is amplification will only go so far until it runs into distortion. For example a hi fi amplifier may have a volume control of let's say 1-10, 1 being low and 10 being high, now I like loud music so naturally I'd crank the volume upto 10 but I know the amplifier possibly sounds its loudest at 8 and pushing it further on to 10 will only creat distortion in the music as the amp struggles to control the sound.

    So what can I do to make the amp work less and be more in control of the sound, well I can up the level of the recording or make the recording louder this will then mean I don't need as much amplification to make it sound loud. We could go into "sensertivity" or 1 watt at 1 meter distance but that opens up another can of worms so to cut a long story short I like my recordings to be as loud as possibly so that I don't have to push my iPhone volume all the way to max to make it sound loud. I use iTunes as a pre amp putting the recordings at 100% in iTunes options means I can have the volume just under the fast forward sign on the graphics in stead of having to max it out. Remember you iPhone has an amplifier built in to it and can suffer from distortion like the detail I put above about hi fi amps. A loud clean signal needs less amplification to sound loud.

    Still with me?

     

    Ok I've have tried and tested different ways of adjusting the volume of my recordings and how the sound compares over different systems. I'am fortunate that I've spent the last 20 year producing music and having to deal with different band widths and frequencys so apologies if I sound anal, I just like a pure clean loud sound.

    My test kit is Apple ear buds, sennhiesser HD 25, grado 600 headphones and a full Naim hi fi system with Sonus faber speakers.

    Before I forget TheBossPower mentioned that he couldn't notice the volume difference between 0% and 100% in iTunes Options. Well there is 1.5 db difference in sound loudness between the two and ok you may not notice the sound difference but how much more iPhone volume do you need to apply to make your music sound at a level your use too? But please also remember we have all got different hearing so one mans loud is anothers quiet.

     

    After following Gianni nyc recommendations it does bannish the dreaded bass distortion but also lowers the sound output of the recordings meaning more iPhone volume required to get the same loudness as before. The only reason I wiped iTunes of my mac was to test to see if iTunes itself was the cause of the distortion but it didn't so there's no need to do it. As my previous post states I brought iTunes options volume down to 50% and while the sound is louder than 0% the music is still creeping into distortion something that never happened before update ios 5. Also I have noticed that the sound is ever so slightly different. The bass sounds a little artificial or as if someone has nudged the bass EQ up slightly, very deep bass can get muddled within the mid bass and high treble again something that never happened before.

     

    To conclude I am without doubt that the sound has been altered in some way from previous and for me it's in a negative way. Yes I can live with lowering the iTunes options volume to 0% or even to 30% but I have to max out the iPhone volume which I know means the iPhone amp is at its limits.

    Gianni nyc recommendations will fix this issue and I agree with TheBossPower this is just a fix and apple still need to address this problem. I pray for the nxt update to fix this issue because I have two alternatives, sell my iPhone and go back to iPod and phone or I'm going to jailbreak the iPhone and put it back to 4.2 os oh and apple this is the last time I update my iPhone my last iPhone 3g  lost its wi fi use after ios 4 update.

     

    Thanks to Gianni NYC, TheBossPower, and all other peeps who have helped.

    Stufromwhitney your not the only one with that issue I've read elsewhere other people having that same problem. Think there's a post on here that has his flash go off everytime he gets a message and I've noticed safari dropping out on me more than usual since the update and my touch screen locks up which I've never experienced b4. Is it just teething problems in ios 5, well let's hope so. I will hunt around for tones fixes may I ask are they tones suppiled with the iPhone or tones you have created? Any 20 sec track or sound can be used as a tone.

    Hi RogueRaptor,

    Thanks for the reply, they are mainly the ones supplied with the iPhone with one or two self made ones - but it makes no difference they are all distorted.  If my partner hears Marimba alarm played in that distorted way many more times she's gonna kill me!  :-)

    Many thanks, Stu ...

    Hi Stu

           From what I believe any custom ringtone or ones you've made up will be kept under the Ringtones folder in iTunes. From there I think you can alter the volume just like you would do with your music, right click on ringtone options, volume. I'm not at my mac so cannot confirm but if you can change the volume have a play around with it. As for the iPhones own ringtones I've looked all over the net and have found many other people with the same problem but unfortunately I can't seem to find a fix. Keep this site updated with any progress you make and let's hope apple realise their mistakes and rectify them. Trouble is apple recommend you update for Sercurity features and to stay up to date but in the small print of the acceptance page b4 you update it says that if your hardware goes tits up then it's not there fault and you haven't got a leg to stand on. It's a lot of money to burn when it goes wrong because of an update.

    As an update to original posts ive updated my firmware to ios 5.0.1 and this hasn't fixed the issue with high bass distortion. I reset my iTunes options volume to 0% syncd with my iPhone 3gs then upgraded the firmware, once complete I altered the options volume back to 100% resync'd my iPhone and the distortion is there with huge presents again so no fix for me. I'm now left with the only option I have and that is to down grade the firmware back to 4.2. I don't understand why apple changed this option in the first place maybe for music down loads or things to come but for me it's ruined my musical pleasure on a device I've paid thousands for. Will this firmware eventually squeeze the 3gs out of the running like the old 3g, probably. Think I'll wait for the 5 release next year maybe my trust and loyalty for apple will have regained by then.

    Hi,

    I upgraded to 5.0.1 thinking it could solve the distortion issue but I also don't think it solved it. In my case the distortion happens some time after a reboot of my iPhone. Also, I never changed the Options Volume, so all songs are at 0%.

    I'm experiencing the same issue ever since I updated to iOS 5. Low volume and somehow distorted audio, especially at the bass level. What can we do about it?

    On iphone4 I've found that just killing and restarting the music app immediately fixes the issue for a while. Anyone else 2nd that? A simple workaround until Apple releases a permanent fix.

     

    For distorted screen unlock and alarm sounds I have to reboot the phone.

    Do apple is listening to us? we need the same quality of sound even after we keep the volume level on +100%, my ipod was having very clear sound before updating this ios5. Need solution urgent or some upgrade

    Agree with everything written on the subject of distortion. I am a discerning audiophile and noted the difference immediately after the update. Apple has definitely modified the equalizer causing distortion to most of my music collection, except bass "light" music. I have great ear buds - not cheap - that are not the cause of the distortion. Listening to i-Tunes, with no distortion, on my laptop confirmsed it's the ios update.

     

    Quick fix for me: Change the equalizer under settings/music/EQ from Flat > Bass Reducer.

     

    Yes, some of the deep bass has gone but is compensated by a large reduction in THD.

     

    Playing with/without Sound Check doesn't improve the THD.

     

    So Apple, acknowledge the THD impairment caused by the update and do right by your paying customers by introducing a fix.  Get your head out of your i-Cloud and introduce a fix with your next update.

    We need Urgent FIX for this, i am getting irritated now, How much to wait for a fix?

    Like everyone else here, I've also experienced some terrible distortion after updating to iOS 5. There's no doubt that the EQ has been flavored/altered and it's screwing up the quality. However, being an audiophile, I've been tweaking for the past several hours and I think I've figured out how to mostly nullify the issue.

     

    First off, the 'Sound Check' option only removes the distortion if the file is supported by the new iOS. If the song was downloaded directly from iTunes or the song was uploaded to your Library from an Audio CD, Sound Check will fix the distortion, but it will also drastically lower the volume of the song (but all you have to do is turn up the volume and it sounds perfect).

     

    However, if the song is in mp3 format (like most music files are), Sound Check WILL NOT change anything. Mp3's are for some reason not supported with Sound Check, resulting in distorted quality regardless of whether it is On or Off.

     

    The way to fix distortion for mp3 files is this (be warned; this may be very time consuming):

     

    1) While in iTunes, select 'Music' in the menu under your iPod

     

    2) Right click any song that is in mp3 format and select 'Get Info'

       If you can't remember which songs are mp3's and which are not, try and find where the song are located in your hard drive and click on them to see what format they are. If they are mp3, well, obviously they are mp3's. If they are mpeg-4, wma, etc then they ARE supported by 'Sound Check' and you don't need to do the following steps.

     

    3) Go to 'Options'

     

    4) The 'Volume Adjustment' bar must be lowered dramatically to below 0%.

       You're going to have to play around with this, because unfortunately there is no sweet

       spot that makes every song sound normal again, but I have found that a great place to start is

       at -40% which is precisely two tick marks to the left of 'None' on the bar.

     

    5) After your iPod has synced this change, listen to the song on your iPod to be sure the quality is no longer distorted, too loud, or too quiet.  Continue to either increase or decrease the Volume Adjustment bar until the quality has returned to normal. This is the time consuming part if you're an audiophile like me.

     

    6) Obviously, doing this one song at a time would take ages, so be sure to highlight any songs that belong together (For example, if you have an entire album of a certain artist, highlight every song in that album at the same time) and then apply steps 1-4 so that when you adjust the volume, the entire album recieves the change at the same time instead of one song after the other.

     

    7) You can attempt to do steps 1-5 to every mp3 on your iPod, but I don't recommend it, because every album and/or song is produced, mixed, and mastered differently and trying to make the same exact change to all of them won't necassarily fix all of them. Some songs/albums are louder than others, many are much bassier than others, etc so trying to lower the volume on all of them simultaneously isn't going to be a magic fix sadly. Plus, attempting to alter that many files on your iPod at the same time could take a long time for iTunes to sync

     

    I have A LOT of music on my iPod and I'm very picky about the exact sound of my music, so this took me a few hours to complete. However, if you a person who isn't particularly picky about the sound of their music, then this shouldn't take you very long.

     

    Just remember, files downloaded from the iTunes store or uploaded to your Library via an Audio CD will work fine when you turn on Sound Check. The volume is lowered, but the quality is restored and you simply turn the volume up. Your goal is to get your mp3's to the same volume level as the rest of the songs on your iPod after you've turned Sound Check on. Once this is accomplished, your music will sound normal again.

     

    I hope this helps. My music is now all completely normal again, even with the Bass Booster EQ setting that sounded horrid with the iOS 5 changes. Best of luck to all of you!
