Some test from my own nForce Audio.
Audio Diver : 5.10.2860.0000
1st tests :
Sample rates, Analog External Loopback
16-bit, 44 kHz:
Summary
Frequency response (from 40 Hz to 15 kHz), dB: +0.17, -0.78 Good
Noise level, dB (A): -82.0 Good
Dynamic range, dB (A): 81.0 Good
THD, %: 0.0053 Very good
IMD, %: 4.036 Very poor
Stereo crosstalk, dB: -71.3 Good

16-bit, 48 kHz:
Summary
Frequency response (from 40 Hz to 15 kHz), dB: +0.25, -0.56 Good
Noise level, dB (A): -83.2 Good
Dynamic range, dB (A): 82.5 Good

16-bit, 96 kHz:
Summary
Frequency response (from 40 Hz to 15 kHz), dB: +0.25, -2.07 Average
Noise level, dB (A): -82.8 Good
Dynamic range, dB (A): 81.2 Good
THD, %: 0.0037 Very good
IMD, %: 0.045 Good
Stereo crosstalk, dB: -72.1 Good
General performance: Good
http://cal003104.student.utwente.nl/nForce/Analog loopback 16-bit, 96 kHz.htm
Conclusions :
@44.1KHz we see a high InterModulation Distortion >4% @48 and 96KHz the IMD is good, this can be explained because of the fixed 48KHz sample frequency of the nForce audio, so @44.1 the high IMD is caused by the sample-rate-conversion. @96KHz sample-rate-conversion doesn't give such a high IMD because the sample-rate-conversion-ratio is 2.00 round.
@96KHz we see the DAC and/or the ADC is and the end of its capacity, this explaines the -2.07dB at 15KHz. This also occurs when using an external DAC so my guess is this a problem of the ADC.
So use 48KHz for highest quality recording.

http://cal003104.student.utwente.nl/nForce/Digital Out AC3 - ADP303 16-bit, 48 kHz.htm
Conclusions :
Stereo Digital out gives a better frequency response than analog (only when using a good DAC!!!)
AC3 out gives very strange results, I think the results one gets here are very dependent on drivers, also AC3 out is always lower quality than Stereo. However when using Digital Out Stereo to your receiver and decoding Pro-Logic sound quality should be worse than AC3.
For highest quality output use a external high quality DAC
People that are using speakersystems like 4point surround and DTT-whatever sets, should first upgrade their speakers/amplifiers and don't worry about better DAC's first.
Marcelo3d : It looks like the DAC in your sony isn't too good, however it might as well be the quality of the pre-amp or the tone controls. Try using a tape-out instead of pre-out to bypass pre-amp and tone-controls. There is however a possibility the receiver wont output digital in to analog out. When program crashes on crosstalk export you swapped left-right channels.

Hows your audio quality in iTunes

I've noticed that audio in iTunes sounds like it's in a echo chamber. Not all, but allot of my library sounds this way. Listening to a song that I've loaded from CD has an echo effect, and then listening to the same song on a CD player sounds normal.
I've used different settings in the iTunes Equalizer, no help there.
I'm using Klipsch THX speakers. Creative SB Audigy Sound Card with latest drivers.
Anyone else ever experienced anything like this?

Hi,
don't know where i saw it, but i have heard it helps so try this.
Open Quicktime, go to Edit, Preferences, Quicktime Preferences, Audio, Sound Out and then select the highest Rate & Size supported by your soundcard, this may help, i am running Itunes Audio at 160Kbps through a Camebridge Audio Amp with some Eltax speakers and the sound is awsome! Mostly Rock music and Metal.

Audio quality degraded when imprting FLV file to Flash FLA

Hi,
I have created a FLV file using Adobe Media Encoder CS5.
I have played it back on Several Media players and it sound fine.
I import it into a Scene in Flash CS5 aand when I preview the Scene the audio has degraded and sounds terrible.
The audio is mono at 48 kbps.
I cannot find any controls or options to edit the audio of the video.
I have rendered it out several times using different settings but it alway plays back the same highly compressed tinny sound.
Any advise?

Try with your publish settings in flash to adjust your audio quality while publishing, look into the below screenshot:

Does Encoding AAC Files with VBR on Improve Audio Quality ?

Does Encoding AAC Files with VBR on Improve Audio Quality ?
Are there Disadvantages ?
Bonus Question 1:
Usually, an 'auto' type encoding tool will screw up the natural flow of the music and miss subtle changes in the energy, volume, etc.. -stuff that is just to subtle for it to catch -Generally I wouldn't trust an 'auto' type setting to pick up this subtle stuff. Yet people say using VBR improves sound quality (and NOT file size). Why and how ?
Bonus Question 2:
What is the max bit rate VBR uses ? If I set my AAC encoder to 320 kbps and turned VBR off, wouldn't the sound quality be superior to encoding with VBR on (simply because the kbps are set at 320 the whole time...) ? Sure, the files encoded with VBR off would be larger, but wouldn't the quality be better ?
Bonus Question 3:
Lastly, I did a little test and encoded one song with VBR off and one with VBR on. The VBR song was 1.5 MBs bigger - Huh, I thought, is that increased file size the result of improved resolution throughout the whole song, or just one little section (haven't had time to listen to them)?
Message was edited by: temptemp9

These are some pretty tough questions. I like VBR encoding in general, as it does allow for more complex passages to take advantage of higher bit rates while less complex passages fall back to a lower bit rate, while keeping within fairly consistent file size parameters. Whether VBR yields better results at different target/average bit rates is another matter, and really requires that you encode and properly test output files before deciding on anything but "recommended" settings.
At maximum lossy bit rates of 320 kbps, it doesn't make sense to use VBR. If I recall, the LAME MP3 encoder presets actually preclude VBR encoding for the highest quality files, and the same may be true for iTunes AAC.
I have to admit that to speak with any certainty or confidence about the issues surrounding your various questions, one would really need to encode a bunch of files with iTunes from lossless sources and test them in software such as foobar2000. I could investigate this easily on my own PC, but I don't encode music at 320 kbps AAC, since I have enough disk space to just listen to lossless files. iTunes doesn't display dynamic bit rate changes as foobar2000 does, and I haven't come across any Mac software that does as good a job of allowing for proper testing as foobar2000 for Windows does.
If you really need definitive answers to these three questions, then I think your best bet would be to do as I've hinted and use iTunes and foobar2000 if you've got access to a Windows computer to do this testing and evaluation for yourself, or sign up for a user account at Hydrogenaudio and post the same message there.

"audio quality" Audigy 2 vs. Nforce onboard

5"audio quality" Audigy 2 vs. Nforce onboardS hi everyone,
i bought myself an old Audigy 2 from Ebay a week ago, hoping i can increase my fps ingame on my old 2200+ computer.
i really felt the increase, especially in Doom 3. But today i threw out the Audigy again.
the bass from my subwoofer (teufel concept e mpe) is sooooo weak (in games and winamp) and sounds like a cheap passi've subwoofer.
i tested every single setting, hoping to get a better sound out of it, but it didn't work. the bass just feels "weak".
i'm pretty surprised, because i thought i'd get at least the same sound quality.
does anyone have experiences with that? i can't believe the onboard sound is better than the Audigy's!
i set the frequency for subwoofer to 20hz, increased the volume of the subwoofer, changed the equalizer.
but it just sounds like a passi've sub and "cheap". (sry my english isn't good enough to find fitting adjecti'ves)
can anyone help me with that? does anyone have the same problem?
thanks in advance.

If you used the auto update function you're probably already using the latest drivers. However if you didn't then definately install Dan K's pack - they're the best drivers currntly available for the Audigy 2. You'll want to uninstall the previous drivers, then do a clean up using Driver Sweeper beforehand though - Creative's drivers can be problematic
The problem with the Audigy 2 is that its analog output quality isn't especially good anymore, when compared to newer devices - even onboard. This is demonstrated when and if you swicth over to use Dolby Digital Li've.
I'm assuming the sound quality improvment I got has got to do with the fact that when using DDL, the Audigy's DACs and other analog components are skipped because the audio signal is being sent straight out, digitally, to my reciever.
The audio quality improvement I got was huge, to the extent that, eax/gaming aside, I can't actually hear the difference between an X-Fi and my Audigy anymore. Before using DDL li've the difference was obvious.
It may simply be that your nForce's analog output is of a higher quality.
Analog quality aside though, the Audigy 2 is still the better device, or at least the more capable. It really depends on whether or not you're a gamer I suppose.
If you've got a digital reciever then try the DDL pack and connect your Audigy to your reciever using the digital output.
If not, and you're not a gamer, then I'd stick with your nForce if that sounds better? < - this being advice I'd imagine you must find rather anoying.
Message Edited by Meocene on 08-0-2009 03:5 AM
thanks for these informations.
unfortunately i can't use DDL, because i don't own a receiver.
music is at the moment the more important thing, i'm gaming about 4 hours a week.
i'll keep the audigy though, maybe i'll rebuild an old 3000+ system i still have. (the sound THERE really sounds crappy)
thanks for all answers and your help!
EDIT: does the usual audigy 2 driver panel look like this: http://www.hartware.de/showpic.php?type=review&id=606&path=/media/reviews/606/xfi_screen_thx_big.jpg

Ableton Live 6 vs Logic Pro 8 CPU usage/audio quality.

Hi,
Any user's have feedback regarding CPU usage between Abelton Live 6 vs Logic Pro 8. I'm currently running Live 6 on an MBP 2.0ghz (CD) and am constantly running into audio drop outs etc etc.I am reading throughout the net that Logic Pro 8 is more CPU friendly than LIve 6... is this true, overall? Also any users ever do a mixing test between the two apps to see if there was an audio difference when rendering your final project to aiff or wav? I am thinking on using Live 6 as a stratch pad to "create" as I enjoy it's flexibility then transfer the project over to Logic, however that depends if there really is a difference in CPU usage and Audio quality between the two DAW's.
Thanks.
guess i should also state that i will be running on the new imac's come tax return time. lol

Logic 8 is very CPU friendly, I can say that much. I never found Ableton Live 5 to be very taxing either, though. Pro Tools is.
But like you I use Ableton as a scratchpad, I love how it works, and Logic for the finishing touches. But that's just because I'm not good at Logic yet. Not fast at it.
Get them both! You'll be glad you did.

Audio quality gone south after upgrade

i got my bb 8520 in October 2009, the audio quality on phone calls was absolutely perfect and far better than previous normal cell phones (this is my first smartphone). A few months ago (i am writing this in October 2010) i plugged my bb into my pc and was told there was a operating system upgrade available - i can't remember the version it upgraded to, but the upgrade from a software ease of use and visual perspective has been well worth it - BUT since then the audio/sound quality of phone calls is absolutely horrendous and sometimes i cannot hear the person on the other side - it now sounds like the speaker in the phone cannot handle the volume (that sort of problem), but the volume is on the lowest level, bass and treble are on normal etc - i have spent hours on the phone trying different options, but the problem persists.
please help me!

Hello jed-sa and welcome to the BlackBerry Support Community Forums.
I would suggest doing a clean software reload. KB11320 will show you how to do this reload.
Be sure you back up your BlackBerry before starting as all user data will be deleted.
After the reload completes, test without restoring any data.
It is suggested to do a selective restore of data so the issue doesn't reoccur. KB10339 will show you how to do the advanced restore using Desktop Software 5.0.1. KB23680 will show you using 6.0 Desktop Manager.
Let me know how you make out.
Thanks! And have a great day

How Do I Improve Audio Quality on Face Time

Can anyone advise how I can improve the audio quality on Face Time?
Video is acceptable, but audio sounds like a long distance phone call back in the bad old days, lots of background noise and voices barely audible.
I don't think its my internet connection, currently ADSL2+, Line speed 4.9Mbps, download speed 617KB/s

Welcome to Discussions, Little Eddy
Depending on whether you mean sound you hear or how you sound to others, here are some ideas for your consideration:
(1) Call from an area with less background noise.
(2) Use an iPhone. Its sound quality is superior to iPod touch.
(3) Try http://store.apple.com/us/product/MB770G/B It sounds better in my tests than internal mic.
(4) For FaceTime on your iMac, sit closer to the Mac's mic. Also test speaking louder.
(5) For FaceTime on your Mac, try a USB mic like http://store.apple.com/us/product/T6831LL/A
(6) Both you and your connection should test with other users to determine who has the problem.
(7) If sound you hear from other end, ask your contact to double check that his mic is not obstructed by a case, fingers, etc.

Cover Art, importing, & audio quality

In the process of ripping my CD's into iTunes in my Mac Mini I've noticed that iTunes doesn't always import the cover art. I know that this is a known issue among many posts in the forum but wanted to confirm that if the album isn't sold in the iTunes Store you won't get the cover art even if you are ripping your own CD's into iTunes. Is this correct? Also, is there no way to use something like Gracenote to import the cover art or do I have to do it manually. What is frustrating is that Windows Media Player on my Dell PC fnds these same CD's cover art no problem. Why can't iTunes do the same? Any thoughts or suggestions on an easy way to import missing cover art would be appreciated.
Also, I have a large amount of music files on an external hard drive that was originally connected to my Windows PC. What is the best way to import this music into iTunes on my Mac Mini?
Finally a question on audio quality of the various codecs available for ripping CD's into iTunes. I noticed that the ALAC encoding bit rate varies by CD whereas ripping as WAV always uses 1411 bps. I know ALAC is a lossless compression codec and so I am in the process of comparing the quality of the various codecs but was curious if anyone has any comments based on listening tests.
Thank you to all who reply with information.

I checked the latest episode and the MP3 file does not have an image embedded in it.
This is the method for adding it in iTunes on a Mac (I assume Windows would be similar):
Open iTunes and add the audio file to the library. Select it and hit command-i. Select the 'Artwork' tag. Drag your image to the space. Close, and when you play the track you should see the artwork. Drag the file out to the desktop and upload this version to the server. You can delete the copy in iTunes if necessary but if you are storing the file elsewhere you should replace it with this new version (which looks just the same, and note that the cover art does not appear in the QuickTime Player).

Audio quality on Apple TV G2.

I bought my Apple TV (G2) with the goal to no longer put my CDs and DVDs in a CD/DVD player and so have my audio library, concerts and movies cataloged into iTunes.
I've converted all my CDs (which are originally stereo) to MP3 but now I need convert my DVDs. The big question is regarding the audio quality, because most
of my DVDs has original sound in DTS. How do I convert the DVDs to make sure the Apple TV will play the 6 channel (5.1) with the same quality as the original DVD?

For audio, I did two tests:
FIRST TEST:
In this first test the file was played perfectly in iTunes (MacBook) and AppleTV2. Theoretically, I've got a 5.1 audio in AppleTV2.
SECOND TEST:
In this second test, iTunes perfectly played the file but AppleTV2 had an error and didn't played it.
You are still creating single track audio files. What nightstorm and I were suggesting is that you use the default audio pre-set also. This should ensure compatibility across both systems and devices. Some users have complained that movies containing only the AC3 audio track won't play on their TV devices. Others state that they do play. On my system the ones I've tested with only AC3 audio do play, but since this represents only a few random tests, I cannot say that all such files made this way will play. On the other hand, all of the files I've made with AAC only and AAC + AC3 audio tracks have played correctly (other than my initial 640 Kbps AC3 passthrough test made a year or so ago).
Once again, as you can see, the default Audio preset creates two audio tracks. The first, a stereo AAC track is encoded as Pro Logic II audio using a target data rate of 160 Kbps with a 48.0 KHz sampling rate. This track is the "default" audio used by systems and/or devices not capable of playing AC3 DD5.1 audio. In addition, if connected to a "active" PL II decoder, it will play surround sound. While not true "discrete" surround audio, it is generally audibly better than "passive" PL decoding. As to the AC3 DD5.1 track, it is normally played by "default" when played through an TV device connected to a AC3 DD5.1 decoder equipped TV, receiver, or amplifier and the user has not turned off the passthrough capability.
Here are the statistics for two test clip snippets taken from the same file encoded using my TV preset. As you can see, the audio and video data rates can vary by quite a degree during encoding. This will give you some idea as to how movie content can "drive" the encoder during the compression process. In the first snippet, there is a rapid close-up pan (very difficult to encode) and frequent loud noises in the background that help to drive up the data rates. The other snippet is what I tend to think of as a typical average indoor scene. In any event, I have uploaded both test files so you can download and test then on your system and/or TV device if you wish. I would be interested to know if they play correctly in both iTunes and on your TV2.
Test
Test2
Now I have the following questions:
- Will I get the best (same as the original AC3 5.1 source) audio quality with AAC?
- Why my AppleTV2 couldn't play the content with AC3?
Apple recommended preset is 64 Kbps data rate at 44.1 KHz sampling rate per channel. (I.e., 128 Kbps at 44.1 KHz for stereo.) When listening to things like piano overtones or rain falling on an empty street, I can hear a difference between these settings and stereo 160 Kbps at 48.0 KHz. So I admit I do use the latter for may AAC track. However, as I am on the "high side of 65" and my hearing is not as good as it could be, I really do not hear any differences above these settings. If you want you can try using stereo 320 Kbps at 48.0 KHz and see if you can hear any differences in the quality. Frankly, your target data rate of 448 Kbps seemed higher than necessary for stereo.
As to a comparison of AAC with AC3, a stereo 160 Kbps/48.0 KHz audio track is supposed to equal a stereo AC3 track at 192 Kbps/48.0 KHz which is the standard for DVD. As to AC3 DD5.1 the standard for a DVD is 448 Kbps at 48.0 KHz. As you can see if the data rate were divided equally between all 6 channels, the the allocation would only be about 75 Kbps per channel. Luckily, sounds allocated to each of the 6 channels rarely, if ever, require to push the full amount of data through all channels simultaneously. It might be more appropriate to say that each AAC channel has a higher sustained quality potential than each standard AC3 track, but that the increased number of AC3 channels provides a potential for more natural, directional sounds.
As to your not being able to play your AC3 only files, there simply is not enough information to evaluate at the moment. For instance, your system may be one that wants/requires/expects an AAC track be included in the file. Or, as previously mentioned, the audio data rate for your output files may exceed the limits allowed for streaming to the TV2 device. For that matter, while all of my tests were made using the "Auto" setting to output audio at 48.0 KHz, your screen shots of target settings do not confirm that your file output is, in fact, using a 48.0 KHz sampling rate. (I.e., some TVs/receivers may not accept other sampling rates which may be why Apple added the new "16-bit" audio preference setting.)
In any case, see if you can play the files I posted let us know the test results.

Problem with audio quality using Record Audio Comment

I am recording audio comments in Adobe Acrobat Professional using the "Record Audio Comment" tool. The sound quality is bad--very scratchy and has a noisy hum. I am using a good USB headset/microphone. Recordings outside of Acrobat are fine, e.g., in Audacity. I have tried two different microphones with both Acrobat 8 and 9 on two different computers (a desktop and a laptop) with similar results.
I have not found an audio quality setting in Acrobat. Is there some way to improve the audio quality when recording comments? I suspect Acrobat is compressing the audio so much in order to save file size, however, the poor quality makes it almost unusable.
Thanks in advance for any suggestions or advice. I know I can record outside of Acrobat and then add the pre-recorded audio as a comment, but that defeats the purpose.
Bev

Sorry to hear you are having problems.
A few things you can try:
1. Turning the volume of your TV up too high during a call can cause the kinds of audio problem you describe. Try turning the TV volume down and this should stop the 'feedback' problems you are having.
2. If you are using external speakers, then try switching these off and using the speakers built in to the TV. The TV was originally tested for Skype using the TV's internal speakers, so if you have a soundbar or other external speakers connected, the audio performance may suffer on Skype calls.
Best wishes

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?

Audio Quality suddenly failing speakers or card?

Hello
Recently the audio quality if my music files is awful
some songs are distorted, just a rasping sound from speakers
some songs, things like back up vocals, guitar, etc. sound "far away" / not as prominent as they are supposed to, sometimes non existent as opposed to how i know the song is supposed to sound.
but then there are other songs that sound just fine, its confusing.
I am working on narrowing down the prob.
so far i have played known problem songs on another computer, and all sounded fine, so i know my files are okay.
so that leaves either some card in my machine or speakers themselves.
I have those clear Harmon Kardon vertical looking speakers + clear woofer w/blue light.
any suggestions?
I dont wanna go out and buy new speakers if thats not cause of prob.
thnaks

One way to test if it's your Mac hardware or iTunes is to try to play the song in another program. Go to your music folder and select a single track. Control-click (or right-click) to bring up the contextual menu. Select Open With... and when it pops out, select Quicktime.
If you still have the problem, then you've at least elimated iTunes from the source of the problems.
Have you attached your powered speakers to another computer?
Have you checked the physical connection between your Mac and the speakers?
You don't list what type of Mac you have - do you have sufficient RAM? Are you running any other programs at the same time as iTunes that may be eating up your available RAM? Have you tried rebooting?
Please keep us updating on your progress.

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

Test your audio quality.
