IPhone (iOS 5) High Bass Audio Distortion

Ever since I got the iOS 5 update, my music's been sounding very distorted. I know it's not my headphones because I listened to my music with them on iTunes and there was no problem with it but when I listen to the songs on my iPhone, it gets all fuzzy and distorted. Can someone please come up with a solution to this?
And how can I contact Apple?

I have noticed the same problem since upgraded to iOS 5. Nothing to do with Equalizer/Volume settings/Sound Check as these are switched off on my Iphone4 - in iOS4 and iOS5.
I had listened to the same song just before the iOS5 upgrade, and then immediately after the upgrade an hour later. Huge difference!! Songs in iOS5 are now more bassy (but the bad kind). Very disappointed.
In some songs, the increased bass results in horrible distortion and made headphones crackly.
I understand this happens if you are using expensive head/ear phones - someone in Apple has boosted up the Bass setting in iOS 5 in order to make cheaper earphones sounds "better" but unfortunately has a detrimental effect on high-performance headphones (like the £250 Bowers and Wilkins P5).
For more than a year, my songs sounded perfect/natural on iOS4 with Bowers and Wilkins P5, without any need for EQ/Soundcheck....and now iOS5 has destroyed the audio quality.
I hope Apple will restore the music quality in iOS5. Please Apple - return the dB+ settings to their proper levels. Test them with good quality headphones sold in your stores!

IPhone iOS 4 high CPU bug and work around

Using activity monitor app, frequently I notice that the System CPU usage won't drop below 10% with total usage ranging from 15 to 20% (idle never goes above 90%). Closing apps doesn't recover from this state, neither does turning off services, WiFi or 3G. The only thing that works (other than restarting the phone) is to turn on airplane mode for about 10 seconds and then turn it off. The System CPU usage will still be high while in airplane mode, but will drop down to about 2% (6% total) after turning airplane mode off and idle will stay above 90% at that point.
I've tried all combinations of turning WiFi, 3G, location services, etc off and on, but only turning airplane mode on and off works.
I've done a full restore and it still happens. I have no idea what the trigger is. It doesn't seem to be based on what apps are or were running because I've had it happen overnight when not running any apps. It might be based on mail or something, but killing the mail app doesn't fix it. Only turning airplane mode on and off does.
Letting the System CPU hover around 10% instead of 3% causes a noticeable drop in battery life. This needs to be fixed.

Hello,
I have the same problem, and it was the same even for previous versions of iPhone OS. I don't think it's a time zone issue, as I am living in Norway and the reports here are the same from various locations.
However, I think I might have found a workaround for this problem. Normally I have my mail, contacts and calendar synced via Exchange. When I in addition to syncing with Exchange select "Sync contacts with Outlook" in the "info" tab in iTunes on my computer, the dates appear to be transferred correctly. But then again, this gives me several contact groups on my iPhone, whilst I really only want and need one group, the Exchange contacts. Anyway, the contacts appear only once when I select the "group" all contacts on my iPhone.
Hope this can be of any help until the bug is fixed.

Pavilion dm4 windows 7 idt high definition audio codec v 6.10.6324 distorted audio playback

Suspect Windows 'pushed update' changed original IDT High Defition Audio CODEC becasue original worked fine since HP Pavilion dm4/Windows 7 was purchased. Sound plays, but periodically buzzes and is distorted. Have tried both rolling back driver and installing your Support driver sp57966.exe with BIOS load. Still no change, same distorted sound both times. Is there a way to return to original CODEC?

Hi,
Have you tried using Recovery Manager to reinstall your original IDT Audio Driver - the procedure for using recovery manager to reinstall Software and Drivers is detailed in the relevant document on the link below.

Soundsticks (USB Audio) Distortion w/High SPLs...

I have a pair of Harmon Kardon Soundsticks (I've had them for a long time, maybe 10 years) anyway, they have been working flawlessly on my 2006 vintage Mac Pro yet lately the audio distorts when playing it rather loud and with some demanding material...
So, does it sound like there is an issue with the MP or the Soundsticks?
Thanks,
Robert

I have been having similar problems with my (much less fancy) USB speakers, intermittently, since the 10.4.6 update (PowerBook). From another post I made elsewhere:
I have Altec-Lansing XT1 USB speakers. They're connected to the PowerBook via a USB KVM, to an ADC, to the speakers.
For the last week or so (it started soon after 10.4.6 upgrade), an odd temporary sound distortion has been occurring. As the original poster mentioned, it sounds for the life of me as if the speakers are blown.
For anywhere from a few moments (several seconds) or longer, the sound output will become distorted in this way. Then, often of its own accord, things will go back to normal. If I want to get them back to normal more quickly, I can mute and unmute (I use a Logitech keyboard with a mute button, or sometimes I hit the Griffin Powermate which defaults to mute, and occasionally I even hit the sound control on the menu bar). When it's unmuted, it comes back undistorted.
Hence, this phenomenon seems to me to likely be software-related.
I almost always use the PowerBook closed and hooked up to an ACD. Lest you think this is particular to this set up: I have another identical ACD & speakers at the office (indeed, even the same keyboard), with the main difference being the lack of the USB KVM switch being left out. The problem happens there as well.
I welcome any thoughts.
Thanks,
Doug

RE: Macbook Stuttering, Audio Distortion

FYI
As discussed in Macbook Stuttering, Audio Distortion,
The solution to this problem is as follows:
The fix is to blow out nearly four years of dust (in my case), using the instructions given here (for replacing a fan...)
http://www.ifixit.com/Guide/Repair/Installing-MacBook-Core-2-Duo-Fan/522/1
You don't need to remove the fan, but go as far as removing the keyboard, and then you can simply use an air-duster to remove every bit of dust you can find.
If your macbook's heatsink (as in my case) was cleaned by a professional in Apple Store, and you still keep having problems with youtube, ichat, skype and have stuttering, audio and video distortion and your 2+ghz intel macbook behaves as if it's an early iMac G3 - you have to do all steps described at ifixit.com.
When I have taken out my macbook's fan (the heatsink was perfectly sterile) I have found a 5mm thick layer of compressed dust blocking 97% of the air exit.
Removing the blockage has helped and my macbook is operating like it's new.
PS: It's sad that people at Apple Store do not do their job properly.

Your processor is momentarily saturated. It's not really a 'defect' that is covered under warranty.
Flash is a widely-known resource hog. It's one of the reasons that Steve Jobs has 'banished' Flash from iPhones and the new iPad, and uses H.264 format video.
Have you also noticed that the fan becomes loud when this is happening? Almost any time the fan starts running at high speed, it's because your processor is working hard and needs additional cooling.
If you look at Activity Monitor when the stuttering occurs, you probably have a combined CPU utilization of the top two or three processes running of more than 100%.
It's also quite possible that the Free memory 'green slice' of the of the System Memory pie chart is quite tiny.
Work-Arounds
1. Run fewer processes/programs. Close and Quit every application that doesn't need to be running while you're watching Flash.
2. Try another browser. Some are better than others at running Flash. I use Safari primarily, but Firefox, Google Chrome, and Opera are also available.
3. Add RAM memory, especially if you still have just 1Gb RAM memory installed. Upgrading to 2Gb or 4Gb (MacBook 2,1 actually only recognizes and utilizes up to 3Gb) will help somewhat. It doesn't cure the processor saturation, but it does give the programs running more 'breathing room' until it reaches the saturation point.
4. ClickToFlash gives you options for how Flash is handled. Free download here --> http://rentzsch.github.com/clicktoflash/
5. H.264 format videos may be less processor intensive.
6. Buy a new Mac with a faster processor and more RAM. Even a 2.26Ghz MacBook Pro does much better than the 2007 2.16, because it uses a low power microprocessor, has 2Gb RAM standard, has a more advanced video chipset, and an unibody aluminum case to help dissipate heat.

HOW TO MAKE A HIGH DEFINITION AUDIO DVD WITH PREMIERE CS2

I have been working with my CS2 Premiere to create some auto play high definition, audio-only DVDs that are autoplay. To clear the air, yes I know that CS4 will permit 24bit-96 kHz. For the time being 16 bit-48 kHz, is still better (marginally) than CD, but it permits greater playing times. Yes, I know that the autoplay without menues "feature" is bogus, and was never corrected by Adobe. So much for their interest in their customers.
I found a simple workaround for the autoplay/no menues feature. Just make a DVD-RW with menues. Then use DVD-DeCryper/Shrink/Nero - whatever to make an autoplay DVD onto a permanent disc. It works well.
Here is my latest crazy problem: How to get really long playing time. I know I can make high qualitye DVD-A's up to 3 hours using Minatonka Bronze. Unfortunately, DVD-A discs are worthless as they cannot play in 90% of DVD players, but they prove the time point.
I have three 48 kHz files that I created in Adobe Audion. The were 1.599, 0.911, and 0.974 GBs in size. That added up to 3.480. The playing time is about 2:30 Hours; quite a bit less than 3 hours.   I tried burning a DVD with these, audio-files-only. I checked lowest quality video, used no video, and got an Export To DVD error that I had "insufficient" space on the 4.7 GB disc! So, I used the two latter files, which added to only 1.884 GB. Premiere did not baulk, and it successfully burned a DVD that played. Then I added the 1.599 GB file, and, once again, it produced an error. This was clearly not going to work.
At this point, I realized that Audition had done what it liked to do: It had saved the 16 bit-48 kHz files as 32 bit-48 kHz! So, I went back to Audition and used EDIT to change the files to genuine 16 bit-48 kHz files. When I opened them in Premiere, Premiere reported 16 bit-48 kHz files. Their sizes were now, 0.799, 0.456, and 0.487 GB. Please note that this totals 1.742 GB. This is less than the 1.884 GB I had successfully used before.   Once again, I was getting the "inssufficient" space error. This is nuts. The disc can hold 4.3+ GB, but won't fit 1.742.GB.
So, anybody got some ideas?
Mike

Jim,
I cannot believe you are wasting my time and the space of this forum with your irrelevances. It would have been better had you just tried to answer my question, which is the purpose of these forums. Why engage in useless chatter?
I said nothing about any great sonic difference betweein 16/48 and 16/44 digital audio; I said "marginally."   In English that means very little difference. I'm not going to prove to you with distortion and frequency response plots that there is some minor difference, it is a fact of life. You, in fact, just stated a difference. The difference between a 24 kHz cutoff and a 22 kHz custoff is a difference which you give, to back up your absurd statement that there is no difference. This can actually translate to a minor, difference in THD at higher audio frequencies, but who cares?   Well, you apparently care, because your beligerant non-reply to my question was that "fewer...would notice ." In English that means that some would notice.
What my question had to do with MP3 junk, or multichannel sound, I don't know. Why should I do, as you suggest, and make DVD-A's when one needs only stereo? This is a Premier forum, not a DVD-A forum. Why not bother DVD-A junkies on Minatonka fourms? DVDs can handle stereo PCM very nicely. Classic Audio has marketed their 24/96 DADs for many years and so have a few other companies.   They have been well received by some "golden eared" types. I hope they don't upset you. There is a good possibility that DVD may only be around as a "legacy" feature on BLU RAY in future years. DVD-A was DOA years ago and SACD may go just away; DVD-A is almost that. So, PCM stereo sound DVD's are a good bet that the resultant disc will be playable on many people's players as well as future players. The longer playing time that may be available would make listening to concerts easier, rather than breaking them up into segments.
If you want to argue my motives, or tastes, I suggest you go to another forum and discuss you theories. If you actually have something productive to say about the problem I pointed out, that would be welcome.
Mike

Adobe Premiere Pro audio distortion

Hi,
I have Adobe Premiere CS2 and some audio distortion problems. I captured a footage from my Sony DV Digital-8 camcorder. It's a standard DV footage with 16-bit PCM audio. When audio is nearly-peaking (not peaking), it gets distorted in Premiere, but doesn't in other applications (VirtualDub, Media Player Classic, Windows Media Player, mplayer). I'm sure this is because an internal conversion (called conforming) from 16-bit PCM to 32-bit floating point PCM. Project Setting of the Audio Track is 48000Hz 32bit floating point - Stereo for a DV project, despites DV standard supports 16 or 12 bit Audio tracks. In user manual they write the following:
"For maximum editing performance and audio quality, Adobe Premiere Pro processes each audio channel, including audio channels in video clips, as 32-bit floating-point data at the project’s sample rate. To do this it must conform certain types of audio to match the 32-bit format and the project sample rate."
Well, if I'm a professional video editor, I can (and have the right to) decide whether which sample rate and bit-depth are the best for me, but they don't let me set audio other than the default, there is no option like bit-depth available not even when creating a NEW project. No problem if Adobe's genius developers thought 32-bit mixing provides much more quality, but if they forget to implement 16-bit to 32-bit internal conversion correctly, please let me decide to use at least a fallback method.
Thanks for your help

Just looking at the waveform confirmed my initial reaction: Way, way
oversteered. Everything is clipped and your best approach is to
reshoot. That some players can handle this seriously mistreated audio
may be caused by audio limiters. They should, otherwise you would blow
up your speakers.
Well, you can say that and if this sample was a music maximized with compressors, it would distort too. Sony Digital-8 camcorder has an internal limiter, so only soft-peaking can occur, but no serious distortion. Media Players (eg. mplayer) don't have limiters unless you specify an external limiter filter. I've already told this isn't the clip you want me to re-shoot. This is a sample I created to show you the problem. I sent this to one of my friends who has Ulead MediaStudio Pro 7.0. It doesn't distort there either. Have you tried loading it to an audio editor like Audacity or Adobe Audition? You can see no hard-peaking or distortion if you zoom in the waveform.
Waveform at 00:00:00:21. No distortion, only high levels can be seen on this waveform.
Waveform after 00:00:00:21. Soft peaking in right (bottom) channel.
I'd appreciate if someone took this seriously instead of repeating "reshoot it" and "high levels".

Problem with Audio Distortion

I have a large iTunes (v7.2) library with over 110,000 tracks, which I run through the digital line out of a Mac Pro running OS X 10.4.10. For some reason, I'm suddenly getting serious audio distortion on many of the tracks. Some tracks play with distorted, crackling, others play extremly softly. Others play fine. What makes the problem strange is that it occurs with different tracks encoded in different ways: MP3, unprotected AAC, protected AAC, and Apple lossless tracks are all affected. There doesn't seem to be any rhyme or reason to which tracks are affected. Furthermore, I've verified that it's not the tracks themselves...if I run the same tracks through iTunes on another computer (via library sharing), they play fine. Finally, I've turned off Sond Check, Sound Enhancer, and the Equalizer, but the problem persists.
It's very frustrating! If anyone can please help me, I will be extremely grateful. Thanks so much!

System loses the IDT High Definition Audio CODEC Driver ver 6.10.6491.0 after some time

IDT High Definition Audio CODEC 6.10.6491.0 installed in our HP Envy Notebook - C8U19AV with Windows Pro 8.1 64 bit OS, the system will lose the driver. When I go into device manager it appears that the codecs are there but the driver for the audio just gets lost. We have to repeatedly uninstall all the audio components and then reinstall again. This has been the situation for some time. I cannot say for sure but I have reinstalled the driver twice now for my wife and she has done it a few times. We commonly use the laptop connected to an HP2710m display monitor with an HDMI cable. From time to time we plug in Bose headphones as well. The diver revision 6.10.6491.0 was again installed today after fully uninstalling the prior driver. The common signature is the sound does not work at some point and when I go in and check on the audio codec it will report no driver loaded. Any attempt to run the sp63407 install package without ripping out everything will result in the driver install failing as some of the prior files will has security that prevents the over write of the old files with the new ones.
I can seen no obvious reason for this laptop to repeatedly lose the driver. Once the reinstall is done the sound works again but it is a real bother to have to repeatedly reinstall the audio driver.

Hey purplefacemcgee,
With your issue being for Windows 7, and not for Windows 8.1, the troubleshooting steps will be a little bit different. I would first suggest reinstalling your original sound drivers. I have included the document 'Using Recovery Manager to Restore Software and Drivers (Windows 7)', please click on the option for Hardware Driver Reinstallation, and follow through the steps for reinstalling your original sound driver only.
Now once you have installed the original driver, you will need update your sound drivers. You can do both the Windows, and HP updates that are recommended for your notebook from the HP Support Assistant. I have included the document 'Using HP Support Assistant (Windows 7, Windows Vista)', Please click on the option for Maintaining your computer and installing the latest software updates. Pretty much once you do have the HP Support Assistant open click on Maintain, and then Software Updates. Please install all updates that are listed. After the updates have been installed, please restart your notebook, and test the sound.
If by chance you are still experiencing the same issue, I would suggest running the Microsoft Fix It tool for 'Automatically diagnose and fix Windows audio playback problems'. This tool will check the settings, drivers, and services to make sure that it is running correctly, and try to fix any issues. Please follow through these steps to run the tool, click on the green Run now button > click Save > open the download > click Run. What was the outcome of the tool, are you still experiencing the same issue with the sound?
If you are still experiencing the sound issue after the above troubleshooting steps, please let me know exactly what is happening with your sound. (ie, no sound, sound is choppy, or distorted). Does the sound issue occur in multiple programs, or just one? (ie. Windows Media Player, YouTube, or CD/DVD).
Looking forward to working with you!

HT6114 I'm still getting audio distortion when I input audio through the minijack.

I updated to Mavericks, and now when I plug my iPhone in with the miniplug with a male-to-male cord, I get a pitch shift that happens randomly through Quicktime audio recording.
Since I don't have my music backed up on this computer, I input my iPhone's music through a cord and use the audio recording feature. It's worked great for over a year until I upgraded to Mavericks, and I hoped this update would have fixed it since it said "• Fixes an issue that my cause audio distortion on certain Macs."

Is it just sites like YouTube? Can you play music files-mp3/cd ,hear Windows system sounds,etc?

Audio distortion/clipping

Hi
I have an i-touch 32GB, it is the latest version.
The problem is bass is distorted on certain bass songs when the EQ is on and bass booster is selected. I have tried different headphones, with different results. The apple headphones being the worse, but others still producing distortion. I can of course listen to music ok with the bass booster switched off, but obviously I would like this on. Will a complete reset do the trick or has anyone got any further ideas?
Many thanks.

Got it! How did I not see think of this before!
Tried a different format on the Sony HXR-NX5U, Dolby Stereo. And it works.
What I was using before as a LPCM (L for Linear, it's a lossless codec) Codec format which I gues premiere does not like.
Adobe Premiere would probable recognize PCM because it is Non Linear Quantized and older format and it explains why LPCM was distorting - becuase it's on a wider linear scale that exceeds what Premiere supports - it was still seing the PCM part of the code but not that it was Linear.
The audio nerd prevails.
*edit*
Huh, well I don't see PCM nor LPCM in supported audio formats.

HP Stream 13 has weird audio distortion on youtube videos.

I just got a hp stream 13 and for some reason when I play a youtube video the audio will have strange audio distortions that will happen for a moment on the video. The video itself is smooth but the audio will hiccup. I have the most up to date audio driver. This happens in internet explorer and chrome. I even restored the laptop to original settings and its still happening. I played pandora and that was fine. I would appreciate any help on this one.

Hi
I had a similar issue on a HP 15 Notebook PC andh recent s/w updates and a manual cache clean for flash the issue has resolved.
While investigating I noted if I download a youtube clip this played normally, no issues with sound playback namely a "garbled/cracking/compressed distortion sound". This suggested the issue is not in fact with the hardware.
I noted forums on dells web site for similar issues and some high end laptops for other manufacturer's. I noted also firefox was not so impacted as IE using HTML verses Flash player and not all you tube clips displayed the issue. I saw the issue on some BBC news items but not on others from the BBC. I found streaming radio and music no issues issue only occured with Video content when streamed.
I am aware your model is different but the issue appears to be not model or manufacture dependant.
My O/S Windows 8.1 64-bit
Activity:
1. Adobe upgraded to lastest version (http://get.adobe.com/flashplayer/)
2. clear adobe flash player cache run the program "Flash Player" and from the popup "flash player setting manger" select advanced delete "browsing data and settings" i cleaered everything.
