T520i Sound problem (real-time audio)

I`m using my Lenovo T520i i7-2630QM with 8GB Ram for my DJ needs.But i have pops, hisses, crackles and pauses. I disabled the wireless adapter in order to get better results and it`s working but in every 15 min or 30min there is crackles and pops.I`ve run the LatencyMon http://imageshack.us/f/861/212324333434344.jpg/. the highest dpc routin execution is iaStor.sys. any ideas ?

Hi vlad5657
Try updating to the latest Intel Chipset driver using System Update.
You could also try downgrade to HP's Intel LAN driver. (High % causes from this)

You could find more on similar cases on this forums.
By the way, since you are a DJ, you could achieve better sound / customization through Dolby audio drivers instead of using default Conexant audio drivers.
Hopefully, 2012 would be a better year for all of you!

sndpeek is just what it sounds (and looks) like:
* real-time 3D animated display/playback
* can use mic-input or wav/aiff/snd/raw/mat file (with playback)
* time-domain waveform
* FFT magnitude spectrum
* 3D waterfall plot
* lissajous! (interchannel correlation)
* rotatable and scalable display
* freeze frame! (for didactic purposes)
* real-time spectral feature extraction (centroid, rms, flux, rolloff)
* available on MacOS X, Linux, and Windows under GPL
* part of the sndtools distribution.
i have the intention to make the PKGBUILD, but it has no ./configure and its default is to install on /usr/local/

Real-Time Audio Spectrum in FCPro?

Is it possible to do a real-time audio spectrum analysis (i.e., some sort of audio frequency histogram) in Final Cut Pro 4.5? I have some interview audio that has some high-frequency noise, and I'd like to easily be able to tell where in the spectrum it's happening.
Thanks.

True, but the process of exporting the appropriate audio clip to another app, finding the offending portion, then coming back into FCPro to filter it out seems like a lot of work considering that FCPro does have a lot of other audio functionality--and a video spectrometer--built-in. It would be really great if FCPro did this!

Z87 G-45 - Sound problems/ Realtek HD audio

Alright so here is my problem, I just bought a new rig, like 2-3 months ago.
- MSI GTX 770 Superclocked (factory overclock)
- MSI Z87 G-45
- Intel i7 4770k (standard clock)
- Corsair Vengeance pro 2x4GB(8GB) 1866mhz
- OCZ 750W, Bronze 80 + Fully modular PSU.
- 1TB Wester digital, Caviar black.
- Random mid tower case.
So I've set up my rig, without major problems, my friend has the exact same pc but he has a different case and a SSD instead of a HDD. So everything seemed fine, I played many games like AC4, BF4 without any major problems. But I've started playing one of my favorite games, LoL (League of legends) now there I started to get some problems, sometimes when I'd start my game 'the audio would go into a vierd buzzing sound for a few seconds followed by a blue screen.
DRIVER_IRQL_NOT_LESS_OR_EQUAL
The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0xfffff88000b4c000, 0x0000000000000002, 0x0000000000000000, 0xfffff8800f419fa0). A dump was saved in: C:\Windows\MEMORY.DMP.
For a while I didn't do anything about it, because it didn't happen that often, untill about 2-3 weeks ago where it started happening alot. Shortly after another problem appeard, the same buzzing sound would now happen, at the end of the game, either after a win or a lose when I'd click continue to go the end lobby screen. It would happen after I'd press the continue botton, and untill I've reached the end lobby 5-10 seconds and then It would stop. So I decided to google the problem, not much was on the topic apart from saying it was probably drivers, so I reinstalled all my drivers, the blue screen stopped, but the buzzing sound at the end of my game would continue. It got worse, when I'd watch a youtube video and sometimes press back or click on another video the buzzing sound would come back again. This time it didn't stop unless I'd run some other program or game. I was getting really annoyed by this, so I decided to reinstall my windows. I did, I formated my HDD and installed my windows 7 again. Now I've quickly installed drivers, windows updates but I noticed that at the bottom there was a red X beside the speaker, at first I didn't take into account. So then I restarted my pc and I installed, steam. skype etc etc. Now, I went into google and went into youtube wanting to watch a video. No sound, I was like ' is going on, are my drivers not installed' So I reinstalled my sound drivers it didn't help, now this time I didn't install any Ultility drivers and I was like maybe thats it. I went onto the MSI website, and went into utility and got the sound blaster driver. It fixed the problem as soon as I installed it, not for long. I had to restart my pc a few times to complete updates and when I did, no sound again. 'This point im pretty mad'. Along with not being able to install BIOS divers, because it keeps saying that
'The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see if you need x86(32-bit) or x64(64-bit) version of the program, then contact the software publisher' I was okay it, i'll reinstall my Windows again.
I reinstall my windows again, (current one) now this time I didn't rush installing any drivers, sound was fine from the start, I tryed my BIOS again, same message appears. Now I go to install my sound drivers, as soon as I do and restart my PC, there is a red 'x' beside my speaker at the bottom right corner of my screen. I'm like '', so I go to control panel, uninstall the drivers restart my pc and it works fine again. It must be something to do with the motherboard, at first I thought it was my RAM like many people suggested about the so called blue screens, but now I can see thats its not.
Also I'd like to mention I was able to install BIOS update on my other Windows Install, without any problems nor any Audio problems untill the end.

Try installing the drivers from realtek straight, that solved something similiar to me. The realtek drivers are different from the manufacturer MSI drivers.

Adobe Director 11.5 - Real-Time Audio Manipulation?

Hi all,
Firstly, I'm enrolled in a Multimedia Design course in College, and our College is using Director 11.5, hence why I need advice specifically on the older version, not the current one.
Our assignment for one of the courses is to author an interactive visual dictionary - using Director 11.5 - on a topic of our choice. In my group's case, it was the workings of a soundboard.
In an attempt to really increase the level of interactivity and make a superb addition to future portfolios - as well as showing off - we want to include an interactive 'soundboard simulation' which users can play with. There will be three separate audio inputs that play continuously, and 5 dials to increase or decrease certain effects. Those dials/effects are:
EQ - Hi (High Pass Filter)
EQ - Lo (Low Pass Filter)
FX - (Reverb or Echo)
Pan - (Left to Right)
Level - (Volume)
The idea is that as the user adjusts the dials, the audio is effected in real-time with a multitude of possible effects being applied. Is this remotely possible with Director? As far as coding in Director, I'm still a relative novice, but I have a good head for code and a lot of the principles are the same as in Javascript (which I'm also learning and I must say, pretty good at), it's just the syntax itself which may prove troublesome to wrap my head around at times.
But for now I'm just asking if this is even possible. At our current level of Director proficiency, we're sort of shooting for the moon, but I don't see anything wrong with that!
The only page I've found listing various audio filters and parameters in Director is this: http://help.adobe.com/en_US/Director/11.5/UsingScripting/WSCB4744EA-6E6E-4b85-A946-E2C6E3A 4450D.html
However, I'm not certain that those can effect audio real-time (even just an 'onMouseUp' effect would be fine, but we'd much prefer it be truly real-time).
Any advice, hints, tips, tricks, or directions would be very much appreciated!

Hello Peregrine.2976,
Here is a link to a .dir file that adjusts volume in real time
by setting a variable and calculating volume in play frame as user
slides volume button. Can show more about sound control if needed.

After Effects Playback 27 fps (Real Time) Audio is Slow

Hello,
I have Adobe After Effects CS 5 running on an HP Z600 8 core workstation (12 GB RAM) on Windows 7.
When I import any video AVI, MOV, etc and I preview with RAM the audio plays slow and it reports fps: 27 (real time)
When I link comps from premier I think it is causing lip sync issues.
My co-worker has the identical computer and when importing the same video, his reports fps: 29.97 (real time) and audio play fine.
I have looked around for settings that may affect this but nothing seems to help.
Multi-threading? Open GL issue?
Any Ideas?
Thanks,
Greg

Real-time audio chat

Hello folks!
it's my first post, so, please, forgive me if I'm breaking some rule..
I've thought about an web application I want to develop, but I'm not sure if it's possible and that's why I'm posting my question on this forum.
I want to develop a chat which allows a real-time conversation by voice using JMF (or another solution).. but I don't know how to get started. (is it possible without applets?)
if you could send me some links to tutorials or any sort of aid, it would be really nice.
Thanks in advance!!
p.s. I know my english isn't so good.. so forgive me again
greetings from Brazil!!

(is it possible without applets?)If you're wanting to deploy an application like this on the web, you could certainly do it using JMF, and if you're not wanting to do an applet, you could do it as a Java web-start application.
Here are some JMF resources to get you started learning how to do stuff. Pay close attention to the ones talking about sending audio/video data via RTP, and receiving it.

Real time audio streaming

Hi, I need to develop a j2me softphone, is there someone who can tell me how to do audio streaming ? I already read jsr135 but nothing important.
I would appreciate any help.

Hi Daniel,
I'm encouraged to receive a response!
I can't see how the advent of a new codec will affect the issues that I mention above. You still need an unreliable protocol to transport the Speex data! Datagram support is optional in both MIDP2.0 and it's my understanding that it is rarely implemented. The objection about Bluetooth remains - L2CAP support is optional, and setting the flush timeout on an L2CAP connection is impossible.
Then there is the question of playing and recording at the same time. The anecdotal evidence seems to be that even though you can use threading to start two players at the same time, as soon as you try record and play at the same time, an exception is thrown (sometimes the emulators work but after deploying on the device the exception is thrown).
Finally, you mention that there are a number of Java ME VOIP applications out there. Do you have links? Personally I can't find any. What I can find is a number of products that operate on different platforms:
eg Fring that has Symbian, iPhone OS, Windows Mobile and Java ME versions.
What is telling is that the Java ME version does not support voice, while the other versions do. The same applies to Nimbuzz and Talkonaut. Extensive googling has not revealed any exceptions to this rule.
If you can prove me wrong it'll make my day :).
Cheers,
Fritz

HT5675 will this fix the sound problem? my audio always crashes on browser

if i leave chrome or skype open for a day, the audio will stop working alltogether, then i have to force quit app

I am in the same situation. I've been given the okay to purchase Acrobat 3D. It worked very well with SW2007. I've since upgraded to SW2008 SP3.1 (Vista 64). Now Acrobat won't convert or capture the SW2008 SP3.1 files. The error states that the format isn't supported. I can still convert my SW2007 files, but that doesn't solve the problem
I think Adobe has fallen behind and CAD software companies aren't allowing you to save to earlier versions anymore. I don't intend to purchase Acrobat 3D until this problem is dealt with. I'm not holding my breath.

IPad 2 sound problem, real problem!

So yesterday I was just going to watch a video and the sound was muted so I tried to use the volume buttons but they were not responding so I used the switch to unmute but that didn't work neither. Then I was going to use the volumebar that appears when you touch the video but it didn't show the volumebar, only the pause and skip buttons so today I tried other applications but nothing was working, not the volumebuttons, muteswitch and not the volume bar that should show up when you swipe the taskbar to the right. When locked, the volumebar that would show when you double-click the homebutton didn't appear...
Someone help me!

Start here.
1. Close all apps completely and reboot the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
2. If that fails, look in the dock connector port and see if there is any debris in there. Try cleaning it out with a soft toothbrush very carefully or blow on it and try to remove any dirt or lint... Anything that might be in that opening.
3. Try inserting earphones and remove them a few times in succession.

How can I get real-time audio (think Bloom from Brian Eno out of my ipad and into garageband on my mbp?

I'm a visual artist and an audio novice who would like capture some spontaneous Bloom or Scape musical noodlings. Since neither Bloom nor Scape allow users to save to a universal audio format, I'm hoping that there's a way for me to get those noodlings out of my iPad and into GrageBand on my MBP
Thanks, in advance, for any help

See Recover your iTunes library from your iPod or iOS device.
While I agree that it would be nice if it was easier to transfer media from your Apple devices they should never be used as the sole location for any of your media. They are too easily lost, stolen, damaged, or corrupted. The user tip above also includes a link to a suggested library backup strategy so that you can avoid being in the same position in future.

Possible to make a real-time audio analysis program?

Hi, I was wondering if it is possible to use flash to create a swf file that detects audio levels (or certain frequencies) so that on this event it could trigger a movie clip, or timeline event, if not, does anyone know what could be used to do this?
Thanks!

Real Time Audio Mixing.

Hi!
I would like to mix 2 rtp stream into one. Is there any possibility?
Thanks in advance!:D

Hi captfoss!
I got to create de MergedDataSource, but when I tried to create the sendStream
sendStream = RTPmanager.createSendStream(outputProcessor.getDataOutput(),0);          it throws a UnsupportedFormatException.I use the index 0, because I want to mix all the track in one stream.
The audio format used in the track is ALAW_RTP. So, in outputProcessor I convert the track into this format and I add this format to the RTPManager object.
To do convert all the track of DataSource object into ALAW_RTP format I do this:
try {
     outputProcessor = Manager.createProcessor(mergeDS);
} catch (IOException e) {
       gestor.notifyEvent(createCallErrorEvent(ErrorConstants.IO_ERROR,"IOException. Error en la creacion del Data Source o del outputProcessor al establecer la comunicación."));
} catch (NoProcessorException e) {
     gestor.notifyEvent(createCallErrorEvent(ErrorConstants.CREATE_PROCESSOR,"NoProcessorException. Error en la creacion del outputProcessor al establecer la comunicación."));
outputProcessor.addControllerListener(this);
try
     logger.debug("["+callID+"]OutputProcessor.configure()");
     outputProcessor.configure();
}catch(Exception e){
     logger.error("["+callID+"]establecerComunicacion - outputProcessor.configure"+e.getMessage());
}when the outputProcessor is configured:
if(audioFormat!=null)
     TrackControl track[]=outputProcessor.getTrackControls();
     for (int i = 0; i < track.length; i++) {
          track.setEnabled(true);
     Format [] alawRTPFormat = alawrtpPacketizer.getSupportedOutputFormats(null);
     if(audioFormat.matches(alawRTPFormat[0]))
          Codec[] codec = new Codec[2];
          codec[0] = alawEncoder;
          codec[1] = alawrtpPacketizer;
          for (int i = 0; i < track.length; i++) {
               track[i].setFormat(audioFormat);
               logger.debug("["+callID+"]outputprocessorConfigured - Habilitada pista : "+i);
          try {
               for (int i = 0; i < track.length; i++) {
                    track[0].setCodecChain(codec);
          } catch (UnsupportedPlugInException e) {
               gestor.notifyEvent(createCallErrorEvent(ErrorConstants.UNSUPPORTED_PLUGINGS,"UnsupportedPlugInException al modificar la cadena de codecs del outputProcessor."));
          } catch (NotConfiguredError e) {
               gestor.notifyEvent(createCallErrorEvent(ErrorConstants.NOT_CONFIGURED_PROCESSOR,"NotConfiguredError al modificar la cadena de codecs del inputProcessor."));
     else
          for (int i = 0; i < track.length; i++) {
          track[i].setEnabled(true);
try
     logger.debug("["+callID+"]outputProcessor.realize()");
     outputProcessor.realize();
} catch (Exception e) {
     logger.error("["+callID+"]outputProcessorConfigured - realize."+e.getMessage());
when the outputProcessor is realized:     outputDS = (DataSource) outputProcessor.getDataOutput();
     initSessionManager();
and initSessionManager method is this:private void initSessionManager()
     try {
          logger.debug("["+callID+"]initSessionManager - RTPmanager.createSendStream() ");
          sendStream = RTPmanager.createSendStream(outputProcessor.getDataOutput(),0);
     } catch (NullPointerException e) {
          e.printStackTrace();
     } catch (UnsupportedFormatException e) {
          gestor.notifyEvent(createCallErrorEvent(ErrorConstants.UNSUPPORTED_FORMAT,"UnsupportedFormatException. Error el formato no es soportado en la sesión."));
     } catch (IOException e) {
          gestor.notifyEvent(createCallErrorEvent(ErrorConstants.IO_ERROR,"IOException Error al crear el SendStream."));
     } catch (Exception e) {

     try {
          logger.debug("["+callID+"]InitSessionManager - sendStream.start() ");
          sendStream.start();
          logger.debug("["+callID+"]outputProcessor.start()");
          outputProcessor.start();
} catch (NullPointerException e) {

          logger.error("["+callID+"]InitSessionManager - sendStream.start."+e.getMessage());
Any idea about it?
Thank you very much for your help!:D

Windows Vista - Sound Blaster 24 Bit Usb - No Microphone Playback Real Time Kara

Hi,
I don't no if this problem was just discussed in another thread, if so please giveme simply the link...
I'm Italian, so sorry for my poor english or bad translation...
PC: Laptop, "Toshiba Satellite A 200 24E"
OS: "Windows Vista Home Premium Service Pack " - All update done.
Dev.: "External Sound Blaster 24 Bit Usb" - Driver downloaded from Creative Web Site
At the very beginning I tried the internal Sound Card (Realtek) to do karaoke in spare time, but couldn't hear anything coming from Microphone. So I tried to buy an external sound card. The result is the same.
On "Record Device" I can see the Microphone Device, the level is on top, when I speak in the microphone I can see the green bar light up, if I record my voice I can hear myself when I playback, but no sound in real time.
I read that a lot of people have similar problems, but everone solves in a different manner...
I tried:
- I read in other forums advices about to do something like unmute microphone on "Audio playback devices" >> "Speaker" >> "Levels", but I don't see any checkbox, I can see only Speaker Level Bar...
- As read in other websites, to add a registry key (something like EnableInputMonitor in a specific path), but nothing changes. I cannot find other Device, not in Playback Devices, and not in Record Devices.
Please help, all was great with the same microphone, on old Packard Bell Laptop, old Sound Blaster mp3+ usb, and old Windows Xp.
If no solution, I 'm going on buy an old laptop with Windows xp, or an external Mixer, but I'm disappointed on spending more money...

well ?
