Audio Quality Poor in Windows, OK in MAC

I made a Quicktime movie from an iPhoto slideshow. It plays fine on the MAC, but in Windows the audio quality is poor. The high frequencies seem to be gone. (Perhaps the audio data are being undersampled?) Any ideas as to how I can improve the Windows performance?

Use the QuickTime Control Panel / Audio tab to check the settings used by the machine (sound out). You want to use 44100 Hz and 16 bit sample size.
Clicking on the "Devices" you can also edit other audio settings and properly configure them.
Updating audio drivers may also help and last resort is to use "Safe mode".

Poor Audio Quality From Exchange 2010 UM

Hi,
I'm experiencing an issue with our Exchange 2010 Unified Messaging system in that the audio quality is suddenly rather poor. We are using Cisco Callmanager 7 for our phone system. When you call an automated attendant, hit the "messages"
button or call the extension to go to voicemail, the audio you hear "crackles," or sounds like it is skipping slightly in that there are brief but noticable interruptions in the audio.
The audio quality issue only occurs when you are connected to voicemail or automated attendants, but not when conversing to other people on phone calls, so that leads me to believe either some interoperability between CM and Exchange UM is malfunctioning, or
just something in UM is a problem. Also, if you listen to voice messages through the computer instead of over the phone, the quality is fine. The problem seems to be mainly with calling in to the UM system.
What can I do to properly troubleshoot this? I have found the Exchange 2010 UM Troubleshooting Assistant, but I have to wait another 2 weeks before I can install Service Pack 1 due to downtime window restrictions. I'm not coming up with a lot of
documentation involving this, so if anyone has any information they think might help me get to the bottom of this I would apprecaite it.
Thank you.

Cisco Callmanger and UM are on the same LAN.
I highly doubt that QoS is the culprit here, simply because there aren't any issues with phone calls. If QoS was dropping VOIP packets, then IP phone to IP phone calls would also have poor audio quality. If I call somebody on another IP
phone on the LAN, the audio quality is perfect. It is only when you are connected to the UM system that you hear the poor audio quality -- either listening to voicemail prompts, listening to actual voicemails, listening to the automated attendant --
anything in which UM is on one end of the phone call.
It also seems strange that this is somewhat intermittent. When the issue first occurred, it was definitely happening every time you called in to the UM system and I could repeat the issue by simply pushing my messages button and listening to the welcome
and prompt for a PIN. I restarted the Exchange server at night, and the next day it was intermittent with people calling the help desk to say they were getting poor audio quality from UM but when I tried to repeat the issue I could not.
I also have users complaining of intermittent slowness when using Outlook, which may be totally unrelated. I have been running Perf logs on the Exchange server for the last couple of weeks othe CPU, Network Connections, Exchange RPC totals, etc.
and can't find anything that is using too many resources.

Poor imported audio quality in Captivate 4

Hi Everyone,
I'm having some serious audio quality issues with Captivate 4. I'm recording my audio in Audacity and importing it into Captivate. The audio sounds great in Audacity, Windows Media Player, iTunes, and everything else I've tested it in. However, once I import it into Captivate and press play, it sounds horrible. It's thin, tinny, and robotic. The degradation in quality is considerable. I've tried recording my audio as both .mp3s and .wavs, but they both sound bad once imported. I've also downloaded all of the available patches, including the patch specifically designed to address poor audio quality in Captivate 4. I've tinkered with every audio setting I can find. No luck. I have noticed that the shorter/smaller audio files are less garbled, and really short files are sometimes not garbled at all. I would record directly into Captivate, but the audio sounds even worse when I do that. Anyone have any idea how I can remedy this situation? Just for background info, I'm running Captivate 4 on a macbook running XP via parallels.
Thanks

Hi,
I responded here in the forums because I figure other people might need this info as well.
In Audacity, I go to:
Preferences -> Quality -> Default Sample Format and set it to 16 bit.
Then click OK.
When you record new audio tracks, they should automatically be set to 16 bit.
Does that help?
Shawn

ITunes 10 poor audio quality

After upgrading to iTunes 10, I noticed when playing music from my library that the audio quality is significantly lower than previously with iTunes 9.x. The audio quality sounds muffled and distorted.
I found this thread in the Windows section, but wondered if other Mac users were experiencing the problem as well.
http://discussions.apple.com/thread.jspa?threadID=2571907&start=0&tstart=0
I ended up downgrading back to iTunes 9.x and the problem was resolved. Any ideas? I'm going to end up needing to use iTunes 10 for my new Nano I think ...

Just found the solution! At least for my case. I also had muffled sound and restricted frequency range as it seemed to my ears. And yes, it was the frequency range indeed...
I usually listen through my Sound Sticks but this could also be the solution for other audio interfaces.
Open Apples AudioMidi-Application and check frequency and bit rate for your interfaces' output!
In my case the frequency range was set to 8000kHz for the sound sticks, put it back to 44.1kHz and Tatatataaaa: crisp sound again! (you may have to restart iTunes to have it respect this setting).
I don't know what caused this setting, never messed around in AudioMidi. Something probably went wrong during the installation of iTunes10.
But now have back again the sound quality of iTunes 9.x
Hope this helps you all, it saved me from having to downgrade my iTunes installation.

IPhone 5 Poor Headphone Audio Quality

I got my iPhone 5 a few days ago and I must say the sound I'm getting from my iPhone 5 to my headphones is pure garbage.
I use Beats By Dre heaphones and when I listen to music on my Mac and other devices the audio quality is great, but when I listen to music from my iPhone 5 to my headphones, I hear excessive rattling over the vocals of the music I listen to. I'm assuming it might be the Music app's fault, since I listen to songs from the YouTube App as crystal clear as I do from my Mac from iTunes. I have the same problem with my EarPods: They sound great on anything but my iPhone 5 Music app. Is there any fix possible? Is there any Music app alternative I can try? I'm tired of searching for the songs I want to hear on YouTube everytime to get good sound quality...In short:
Sound quality from the Music app: Really poor quality, I can't stand it.
Sound quality from anywhere else on my iPhone: Crystal Clear
Does anyone get the same problem/complaint from their iPhone 5's?
Side Note: I do purchase my music from iTunes, so I should get good sound quality.

Hey, I recently discovered that when I purchase music from iTunes directly to my iPhone, the sound I get is crystal clear. Do the test with any song: Listen to it before downloading the song from iTunes > Delete it > Download from iTunes from your iPhone > Listen again.
The problem is that not all my music is from iTunes, most of my music comes from CDs. Another thing I must point out is that I can't figure out whether to blame the new Lightning Connector or iTunes from my Mac, since I thought Wi-Fi Sync would solve the problem but I see no changes at all with the music I didn't purchase from my iPhone 5

Poor audio quality in iChat

When I use iSight in Skype it delivers a way better audio quality in comparison with iChat Audio/Video chat. It's not that crisp, more like a poor telephone call. I wonder if I can change it or is it just an iChat nature?
My connection speed is 1 MB.
Straming in Quicktime changed to 1.5 MB
My Output/Input settings in Sound tab seems OK.
I don't use firewall.

Hi Sleeze,
I do not have Skype so I can not judge. Most of the posts I have read seem to suggest iChat Audio is better.
However Skype could have updated their app.
As long as iChat Bandwidth and Quicktime streaming setting in System Preferences are not capping your connection I can not see any other changes you can make. (unless you are "too far" from the camera). If the last is the case it may pay to adjust the volume in System Preferences > Sound >Input tab as this is the master for iChat. I am not sure if it is the same for Skype.

Retina Macbook pro audio quality is bad in windows 8.1

Like the title states, my Retina Macbook pro's (2012 model) audio quality is very bad in windows 8.1. It is unbearable to listen to music on it. I am using the latest bootcamp drivers, 5.1. I believe this is a driver problem, as it sounds fine in OS X. I tried to find the proper driver myself with no luck. I feel this is unacceptable on a computer I spent so much money on. Any help would be greatly appreciated.

Yes...
I also just recently purchased a MacBook Pro retina 15 (mid-2014) with bootcamp (windows 8.1) installed. While using my windows partition, the MBP seems to be running a bit hot, at least hotter than the OS X partition.
As for comparison, I have the 2012 MacBook Pro retina 13 with bootcamp (windows 8.1). It does not get as hot as the 15, and in fact, I don't think it runs hotter than OS X...
Any thoughts? Is it perhaps because I have the NVIVIDA dedicated graphics and in the windows partition, IRIS PRO isn't running?

Poor audio quality when importing CDs (but only some of them)

I am experiencing a bizarre audio quality problem:
When playing or importing tracks from CDs into iTunes 9.0.2, on some CDs there is very poor quality and an audible crackling (like an old scratched lp)whereas on others the quality is perfect. This translates to the iPod as well.
I've looked all over the internet and am now thoroughly confused. Any advice would be greatly appreciated.

If you are hearing it both on iTunes playback and on the iPod, it is probably an importing problem, i.e. the track is bad.
When you import, do your Import Settings use Error Correction? If not, turn it on and re-rip one of the problem tracks.

Lync 2013 and Audiocodes ESBC Mediant 1000 - poor audio quality

Bit of an odd issue that I've been looking into for the past few weeks - our part of our change from a pilot Lync install to production we have had an Audiocodes ESBC Mediant 1000 installed to serve as a Media Gateway between the Lync Mediation Server and
our Gamma Telecom provided SIP trunk.
However under certain situations my users are reporting exceptionally poor audio quality with the Lync server reporting website reporting a very high packet loss and our ESBC reporting a high 'Average voice delay' (often greater than 80ms).
I have established that by taking these steps the issue can be replicated with almost impunity-
Make incoming call from mobile phone (or landline) - pickup call on Lync Deskphone (CX300/CX500/CX600 and VVX410 all have the same).
Begin a consultative call transfer with an external (another mobile/landline) or internal number which places the incoming call on hold.
Complete the call transfer - at this point the audio quality is still as expected.
Begin a new call from a Lync phone to an external number - at this point the audio quality for the phone call that has been transferred and the new call instantly degrades.
My basic topology is-
Fibre Leased Line - Cat5e cable - Router - Cat5e cable - DMZ Switch - Cat5e cable - Audiocodes Mediant 1000 - Cat5e cable - Servers VLAN - Switch - Fibre - Core switch (layer 3) - Fibre - VMWare Host (ESXI v5) - Lync Server (VMNET 3 adapter)
I have been able to replicate the issue when using both TCP and TLS between the Lync Mediation Server and the Audiocodes gateway.
Over the next day or so I will be looking to get the SIP trunk connected directly to the Lync server to see if that makes any difference (ruling out the Mediant 1000 as a possible cause) but in the meantime does anyone have any ideas as to what could be
causing this most weird situation?

Hi,
Please disassociate the Edge Server from the Mediation and check the delay again.
Please check port 3478 to the internal interface of the Edge Server from all internal clients (including the Mediation Server).
Best Regards,

Captivate 8, NeoSpeech Spanish poor audio quality

Hello everyone,
     I was demoing some of NeoSpeech's non-English voices when I had Captivate 7 and they were operating fine. Recently I licensed a Spanish language voice AND upgraded to Captivate 8. Now the audio quality for the Spanish voice is very bad. There's a lot of noise and it sounds like the treble is being over-driven. This does NOT occur with the standard 5 NeoSpeech voices already included in the language pack.
     I reverted my licensed version back to a demo version and the quality is still poor. Audio using the same voice through Microsoft's SAPI sounds clear and fine. It is only when running through Captivate 8 that the audio degrades.
     Does anyone have an idea why this worked fine in Cp7 and fails in Cp8, yet other NeoSpeech voices are fine?

I had exactly the same problem on my new, beefed-up laptop and couldn't figure out how an "upgrade" could ruin my music (which I take pretty seriously). I am embarrassed to say what actually fixed the problem. I started by turning off the EQ and it improved somewhat. I kept searching the web without luck until I noticed something by accident. My system volume was low and the iTunes volume was peaked at max. I turned the iTunes volume to 40% and turned up the computer volume to compensate and voila! The bass distortion and indistinct vocal range was immediately fixed. I turned the EQ back on and was able to use it however I liked. I guess it is like turning up the volume on a radio to max. You get sound, but it gets distorted in the upper range. Hope that helps!

Poor audio quality with iTunes 9

Hi.
This is my first posting and I am hoping members of the iTunes development team look in here.
I recently upgraded to Snow Leopard and I noticed a marked improvement in sound quality using iTunes 8 . Please note I am playing AIFF files through the digi out of my Macbook into a high quality Dac, amp and speaker separates system, in fact the sound was as good as any cd transport I have ever used. I then "upgraded" to iTunes 9 and noticed a deterioration in audio quality, the bass has become woolly and indistinct and small details in songs are harder to hear resulting in a un-involving sound.
I know I am not imagining this as I have done repeated tests using the same file played back via iTunes9, Songbird and Cog and iTunes is clearly the inferior of the three and the poor quality of 9 is being discussed on many hifi forums.
So come on iTunes team either sort out the audio output of 9 or give us audiophiles an easy way to get rid of 9 and go back to 8 without losing our libraries.
ps. love all the bells and whistles but sound quality is paramount.
Cheers
Andy.

Poor audio quality on calls (New York City)

The audio quality for my calls has always been poor. Recently I heard that that is typical for iPhones in New York City. Is that right?
In my experience the most advanced phone in the world sure does sound like a tin-can telephone.
John Link

you might have more luck in the at&t forums
http://forums.wireless.att.com/
i have read press reports about generally dismal 3g quality in NY on the at&t network... i don't think it is limited to iphones, but all 3g phones. since you posted this in original iphone section i am guessing you are on the original iphone which uses the 2g network... i remember reading at&t was reassigning some frequencies that was causing some with 2g phones to experience some issues, i will post the link if i can find it!
be well

I have windows on my mac and lost audio and can't connect to the internet.anyone else having this problem? Or have it installed at the apple store?

I have windows on my mac which was installed at the apple store. I have lost audio and cannot connect to the internet on the windows side. Mac is ok. apple genius and tech support can't help me and say I need to go to microsoft. In fact the tech support was unaware that windows was loaded on by the apple retail store. Has anyone else had this problem?I recently bought fusion thinking this would help bridge between the two( as told by the genius bar) but it didn't help.Any ideas?

hey mate i used to have the same problem and i got computers maintenance guys out to fix it in the end and all it was, was the router.. got a new one and it was all good after that! i think some routers just arent compatible for some reason or another.

Who is suppose to Fix the Poor Streaming Audio quality?

Just a quick question
Who is suppose to fix the bad sounding streaming audio quality?
This this something Google / Verizon / Motorola will fix or is this left for the developers to fix?
I can not stand telling my phone not to update but I cant said the poor audio quality more!!!!
Someone fix this please

I installed 2.2 on the 1st Droid replacement they gave me- no apps, wallpapers, etc were installed since the phone was updated to 2.2 straight out of the box. The battery level was almost full before install. Upon installing 2.2, the battery could not hold a charge within 10 minutes. On the 2nd Droid replacement, I took the same battery that had indicated a 5% battery level and put it into the new replacement (which was on 2.1), and it immediately read as 70%.
I agree that some apps may cause a conflict, however in my case Froyo was clearly the culprit....so to assume that all these problems are self-inflicted is **bleep**.

Exactly, and since the phones are physically identical, that tells me all these problems being reported are self-inflicted - ie; almost surely a result of an installed app, and not the phone itself. That's the only variable, right?

Poor On Call Audio Quality issue

Hi guys,
Im aware everyone has issues while listening to music via the headphones as i have that too. Thats something i can live with.
However, what i cant live it is poor on call quality issues without the headphones. The other person on the call doesnt sound all that loud, clear n crisp to me. I keep having to press the phone more towards my ear to hear them louder and better. Its sub par. Its worse than any phone ive used.
I just switched from an iPhone to this and im very dissappointed.
NOKIA PLEASE FIX THESE AUDIO QUALITY ISSUES!!! This needs more addressing than the battery issues..

Happens to me on Lumia 800 (12070). Usually at the beginning of the call I can hear the other party well but the call quality seems to degrade slowly over the course of the call. I've tried pressing the phone closer to ear and going volume up or down but in some points of the call I have really hard time hearing what they're saying. Then it goes away and I can hear well again. It's not so much volume issue rather than the call getting really unclear.
