Jmf voip audio problems (loops, delay)

Hi,
Im here with a lots of audio problems. Im testing a simple voip app.
The system is winxp, sb live , 3 gb ram, celeron 3ghz
with JAVASOUND:
Loops in sound appear randomly and bad sound quality (i give it up javasound)
with DSOUND:
Random delays in conversations(0-7secs) but no loops at all and good sound.
Pleople complain about the 0-2 secs delay in DirectAudioRenderer...here i am having 0-7 secs! is just me?!?
Some interesting things:
I found that the delay is most of the times unidirectional and when the user that DOES NOT HAVE delay makes a mute (stream.stop()) for 5 secs at least, the delay disappears "completely" in the other side!
When the delay is bidirectional, both have to stop the streams (mute) for some time in order to the audio to "synchronize".
Another thing that seams to help minimize variable delay is starting the receiver player about 5 secs after the RealizeCompleteEvent ( the java examples start teh player imediatly)
Could anyone ever confim this behaviour?
If there is any other solution other than messing with the sources i would be preciated!
Thanks

I see you making a bunch of declarative statements based on your observations on a system you've not given much technical detail about, and then asking questions that border on being rhetorical.
And I can see a request for a possible solution... You asked for a solution to a problem you're having with an application you didn't remotely talk about how you'd implemented ANYTHING. So how you expect anyone in the world to offer you a solution to your vague babble about 5 to 7 second delays in an application they know nothing about is beyond my comprehension.
Do you think its always required a question to get someone to share some information? I actually walk down the street and crazy people offer to hand me their manifesto, religous people shout out my damnation and/or give me copies of their handouts and religeous texts, I go to a football game and people hand me pamphlets for their political candidate, and I'm often handled fliers with information / meeting times for student organizations on campus. And dude, RSS feeds, man...the RSS feeds just push out information all day long, man. It's amazing! All the information being given to me without asking a single question of anyone / anything...
But yeah, if you want help with something on a coding forum, you'd be better of asking a damned question instead of sharing your observations about what your unposted, undescribed code appears to be doing and expecting someone to share information about where 5 seconds may have came from...
Regardless, I'm going to suggest that a normal program travels significantly closer to the speed of light than your implementation does, and as such, you're experiencing a problem with time dilation. I'd recommend you google around for the special theory of relatively, and make appropriate corrections to your inertial frame of reference. With the amount of information you've presented, that's as good a theory as I can offer.
And I'm officially done with this thread.

Audio problems - sound delay on play - and cutting out.

I have an iMac 27" i5 - and having an audio problem in FCP 7.
There is a delay when I press start/play. At first there's no sound and after about two seconds I can hear the sound. Also when I play my sequence my sound comes and goes (cutting out) - not always at the same spot. Scrubbing is also giving me hassles - I first have to press previous- and next frame a bit (to move the play head up and down the time line) in order to hear the scrubbing frame by frame. This happens when I use internal or external speakers.
What can this be - maybe a driver update? But I'm up to date with my upgrades.
Any help would be appreciated.
Tx!

LOL - no worries
I don't have anything else connected to the iMac. Sometimes I have Safari or Firefox open - but I have also tested it without those programs open - no luck. I have not deleted my preferences - what's a safe way of doing that. My sequence setting matches clip settings.
Will keep a close eye on it when I start a new project - with fewer media on the timeline initially.
Thank you for your replies.

Loop browser vs the loops in audio apple loops

My number is different in the loop browser. lets say
show all> i hit reset then all drums, the number is less than that that is what in the drum folder i have in the HD.
same for Guitar and others.
i.e. all the loops i have in the HD are not in the loop browser.
I have all prefs in Loop set to not filter and reset keywords.
is there a shortcut/proper method to show every loop i have in the HD showing in the loop browser.
I thank you all
and have a nice day making music.
glenn

Ht
an honor to hear from you
and i would hope you have 5 minutes to clarify or atleast add your thoughts here. I am puzzled by this.
I went ahead and bought thousands of loops from third party.
i have 2486 elect guitar loops.
and 349 acoustic guitar loops. filter is off
they are reindexed.
In the apple loops folder where i store all the loops, i have created folders for each instrument ( as close as i could associate them ).
i have the guitar electric folder ( 2486 loops ) acoustic (349 ) harp etc etc etc. If i type in names they show ( most seem to ) but one cannot memorize names of 10,000 loops. I cant!
so if i go into the lbrowser i am expecting to see in all guitars a number almost equal to about 2800. Now you say time signature will mismatch that. But you see there is a mismatch of about 600 guitar loops!? that doesnt make sense does it? they are residing elsewhere, where i do not know except ofcourse in my meticulous folder Guitar electric on my HD.
1. Reindexing makes sure that every loop in my HD is in the loop Browser isnt that the case. I dont remember if i dragged all of them over the browser or not.
2. It seems to me ( and see no other options here ) that if i want to be able to peruse all of my loops and have them accessible i have to have the lib>audio>apple loops>folders of loops open so that i can choose those that are not being brought up in the browser and as you say have time signatures that are different?
how do i then bring up those no shows in the browser if they are not showing up ( acc to you )due to signature problems because they might be usable if edited?
3. i could check off favorites couldnt I and then have maybe 2000 loops to chose from. Aint this a kick in the ***?
Im trying to organize as best i can what loops i have on the HD
so that i can see them exactly organized and neatly in the browser, but APPLE has made this very very difficult i think.
i appreciate your time thoughts and forgive me for insisting on an answer here which i may not get.

Best way to capture data every 5 ms (milli-seconds) in the .vi diagram when using "Time between Points, and Small Loop Delay tools" ?

- Using LabView version 6.1, is there anyway to change the "Time Between Points" indicator of (HH.MM.SS) to only (mm.ss), or to perhaps only (.ss) ?
- Need to set the data sampling rate to capture every 5 milliseconds, but the defaults is always to 20 or greater; even when the "Small Loop Delay" variable is adjusted down.
Thank you in advance.

I have no idea what "Time between Points, and Small Loop Delay tools" is. If this is some code you downloaded, you should provide a linke to it. And, if you want to acquire analog data every 5 milliseconds from a DAQ board, that is possible with just about every DAQ board and is not related to the version of LabVIEW. You simply have to set the sample rate of the DAQ board to 200 samples/sec. If it's digital data, then there will be a problem getting consistent 5 msec data.

Macbook Pro XP Boot Camp Audio Problem

I've got a uni body Macbook Pro running XP with boot camp. Everything has been fine for the last 4 or 5 months I've had it. In the last few weeks though, I've been having really annoying audio problems. The only reason I have it XP even installed is for games (Battlefield 2 and Steam). I'd run skype to talk to a buddy and then play the game. Audio was fine, including the mic.
Lately, skype will just shut down out of no where and give me that error message where it asks you to send a report. Also, the audio in Battlefield 2 will just cut out. I'd still be in the game and connected but there would be no audio, except for the game VOIP. Remember things were working fine for months.
First I tried repairing with the Mac disk, then I tried different Real Tek drivers, then I tried uninstalled and reinstalling the game. None of that worked. Finally, I nuked the partition and did a clean install. The first thing I installed was BF2. Guess what. SAME EXACT PROBLEM. Audio cut out about 10 minutes in. In game VOIP was fine but all other audio was gone.
Does anyone have any suggestions or ideas at ALL? There aren't exactly a bunch of different drivers I can try, and like I said I've already tried reinstalled the drivers from the mac disk. I have no idea what else to do.
tl:dr - new mbp audio worked fine for months, lately audio in games totally cuts out. Tried reinstalled game, drivers, etc, didn't work. Nuked from orbit and did clean bootcamp install of XP. Battlefield 2 has same problem, same with skype. What next?

What anti-virus solution are you running in Windows?
Users have experienced crashes and blue screens of death from Norton products. Norton has resolved these issues in their 2009 product line. I would only recommend Norton 2009 products, Kaspersky, and AVG for anti-virus solutions.
Have you formatted your Windows partition as NTFS, or has it been formatted as Fat 32?
Fat 32 will not handle file sizes of 3.5 GB or larger, and, overall, it seems to always cause issues.
Have you tried a SMC reset?

Good luck, and let us know!

UT2004 Audio Problems with Audigy 2 ZS, X

I've been trying to play UT 2004 and am having some problems. Whenever I start a game, within 2-3 minutes the audio loops and the computer freezes. The only fix is a reboot. I had an Audigy 2 ZS installed, and was getting these problems, so I went and bought an X-Fi Music and installed it last night. Tried to run the game today, no luck, the exact same problem.
Would this be a problem with the Audio engine within UT2004, then? I've run other games (Call of Duty, Max Payne 2, original UT, etc) with no audio problems whatsoever.
One thing I would like to say is that music sounds absolutely incredible with this sound card. And, subjecti'vely, I think the games sound a ton better too, but the music processing is top-notch.
Thanks for any help! Here are my system specs:
Athlon 64 3000+ @ 2.6 gHz
DFI LAN Party Nforce 3 Ultra
Corsair XMS GB
BFG 6800 OC
Antec TruePower 430 2.0

Just tried re-installing the game, I thought maybe the patches or my extensi've editing of the UT2004.ini file might have caused it. Nope, still the same.
The card is recognized in the Device Manager, onboard audio is disabled.
Could it be something with the OpenAL implementation? I've read bits and pieces about improper processing, etc- I tried replacing the OpenAL file with the one from the Creative Developer's website as suggested and there was no change.

Audio problems with Yamaha N12

Hey,
I'm using the Yamaha N12 digital mixer plugged via firewire with FCP, and I'm having massive audio problems / sync problems: audio is always about 1 sec delayed. I've checked the a/v-configuration and it seems ok to me. The problem does not occur in other audio apps like iTunes or Adobe Premiere.
What could be the reason? Thanks for your help!

Some TVs have had issues with the HDMI handshake and the Audio. You may be required to use the separate bulkier HD Component cables with separate audio cables. Or try it as a solution on that TV.
I have CHS 435 DVR on a Samsung, and 2 CHS 335s on different model Vizio TVs, all with HDMI, and no issues. Others have reported different issues. I did a search here with the following results. Perhaps this information will help.

Audio problems with galaxy S

Hi all,
i'm developing on Android, via AdobeAir, a voip application that allows users to make audio/video calls.
I'm facing audio problems when testing it on a Samsung Galaxy S.
audio snaps, the quality is very bad and on the other side it's impossible to recognize what it's spoken.
on other devices it works perfectly and the audio quality is great.
any suggestion is appreciated
thk!

I can only offer possible assistance with your first issue. It sounds like your center channel is completely unhooked or disabled somehow. Have you tried running the speaker test, and if you have, do you hear the center channel?

Audio problems with Rezound, post software update

Hi All,
I had my Rezound for about a month before the firmware upgrade and never experienced any issues with audio playback through my headphones. However, since my phone was updated I'm getting consistent audio glitches. There are two types that I've noticed. The first is a high pitched whine that last for 2-10 seconds before fading out; this has happened consistently since the update. The second is a wave of static that's gets louder and messier until I pull out my headphones and I noticed this yesterday for the first time. I thought the firmware update was in part going to fix the Rezound's audio problem.
Has anyone else had these audio issues since the firmware update?
Is this currently a fixable problem?
Thanks!

I also had no problems whatsoever prior to the update, including no audio issues. I have also recently noticed audio problems post update. These problems seem to be very intermittent and I haven't been able to connect their appearance to anything specific. I have noticed 2 problems, the wave of static problem and also a loud "click" that is very noticeable but kind of in the background. I'm ready to pursue other avenues of resolution for all the problems with this phone which I originally loved!! Verizon's answer is "you're stuck with it" or "we're working on it" or "we will send you a used phone" (so I can enjoy experiencing the same problems on a phone from who knows where with who knows what history after paying $300 dollars just 2 months ago)!! I am so tired of having to deal with the boot-looping problem!!! Why is it acceptable to sell or create a defective pricey electronic device with complete impunity? This would not be acceptable and would result in immediate and consequential retaliation in my career! Any one want to discuss what we might be able to do?

AE audio problem - pitch

I am having an audio problem. The RAM preview plays my audio at a lower pitch. I made this screen recording including sound so you can hear it: http://cl.ly/2J471L3v0q3u
I created a new project.
Add an AIF file to the project—but preview the sound clip first so you can hear how it should sound.
Drag the AIF into a new comp.
RAM preview (you notice the delay while it locks existing frames which seems to be another problem http://forums.adobe.com/message/4626528#4626528)
The RAM preview plays the first time through accurately but at a lower pitch the subsequent times.
Mac Pro (early 2009)
2 x 2.26 GHz Xeon
24 GB RAM
10.8
AE CS6
I've tried a full restart.
Any thoughts?

After several restarts and repairing permissions I decided to shut the computer down for a moment. I fired it back up and the problem seems to seems to be solved—at least temporarily.

Audio Randomly Looping

On my timeline on some clips the audio randomly starts looping like a broke record for that clip.
I deleted the .cfa file for that clip. and it starts working again.
any suggestions to fix this for the whole 2 hr timeline no clip by clip.
thanks

Your current thread is concerning your audio problem
with 4-channel .mov files from "...a ZOOM Q2HD".
This thread, and the fix described relates to .aiff audio files.
Two different issues, I'm afraid.

SkypeMACMate for USB phone Audio problems

Hi,
Not sure where to post this.
A friend of mine has a Voip cordless phone (Senda SE-W1D) he no longer uses with Windows driver. I'm interesting in buying it off him if I can get it to work. i downloaded SkyeMACMate and managed to get the phone connected to Skype. I could see me contacts, dial numbers etc. on the phone, only that I couldn't hear anything. I turned on the USB device option in Skye, but still nothing. Then I turned on the USB device in the system preferences and managed to hear the dialing tone it makes as it dials the number, but as soon as it finished dialing everything went silent again..
has anyone any ideas what it could be?
And surely there must be a way of using the phone without turning off the inbuilt speakers of the iMac
Cheers
Manuel

I found the answer on Skype form. Apparently there is an audio problem with the latest version of Skype. I downloaded the previous version (2.5.0.85) and it now works fine.

Workaround for some W510 Audio Problems. Lenovo, please take a look at this!

Hi all
I believe most or all of the people are affected with poor sound quality of W510. I do believe there are some people who bring their laptops along and not convenient to get a external sound card and external speakers on the road. I am not too sure, but what I think that causes audio problem in W510, T410 or T510 is due to the implementations of Combo Audio/Mic Jack. So far, I have not heard any audio problems from X201 or W701/W701ds with a separate mic and audio jack (1 green and red, instead of 1 combo) Listed machines are using Conexant 20585 SmartAudio HD Sound Card.
The workaround is to force install Conexant 20561 SmartAudio HD Driver through Device Manager
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-73721
Problem Partially Resolved
1. Using Audio Director - Classic mode enables you to use both internal speakers and external speakers/headphone simultaneously. (By right, this should be in Multi-Stream mode, due to this driver not programmed for W510). However, the volume of the internal speaker will be reduced by half if an external speakers/headphone is plugged.
2. The sound quality is improved (tested with internal speakers).
3. Solved Irregular Volume Problems.
Drawback of using this driver
1. Using Multi-Stream mode in this case would not enables you to use both internal speakers and external speakers/headphone simultaneously. However it would just make your internal speaker to be louder. External speaker/headphone would not work if Multi-Stream mode is selected.
2. Custom EQ is not usable, if used, only the right channel of internal speaker, external speaker/headphone would work, and the sound quality will be like a spoilt radio.
3. Only Voice (VoIP) EQ is optimized for external speaker/headphone. Using Off, Jazz, Dance or Concert EQ would make you feel that the vocal (singer's voice) is diffused, blurred like excessive 3D effects.
4. Even if any preloaded EQ is selected, after system has been restarted, the selected EQ would still be saved, but the band (31Hz - 16KHz would be changed back to Off EQ) It is ok as it just affects the graphics, not the sound.
I know that Forum Administrators, Lenovo Staff, Community Moderators, Gurus and Volunteered Moderators/Users would be surfing around and looking for new post. Please take a look and leave a post or PM to me, thank you very much.
It is alright if Lenovo don't think that there is any problems regarding the sound in W510. However, I do believe most users/owners of W510 would appreciate if the sound system could be further improved through a better driver or new revision of hardware to something like a T400 standards or something. Some users would spent so much $ just to get all-in-a-box solution and would not want to invest further just for a external card to sacrifice portability and use more $. Finally, I still do believe that W510 audio problems can be resolved.
Best Regards
Peter

Hi ckhordiasma
Thanks for reviving ths old thread. How about trying Dolby drivers? It sounds great and could possibly resolve those issues without going through too much troubleshooting.
The link is under my signature.
Hope it helps!

Audio-midi loops

we use to have in the audio loop browser a ton of audio- midi loops the ones with the green icons . did they dissapeared??? I dindt see them
thanks

No they haven't dissappeared. Maybe you should set the Loop Browser view to "All" to see all the Loops available-if the green loops still don't show up something went wrong during Installation.

GB won't open- This is what I get... Path does not exist: /Library/Audio/Apple Loops Index st: /Library/Audio/Apple Loops Index w/out this directory you cannot use the Loop Browser

Path does not exist: /Library/Audio/Apple Loops Index st: /Library/Audio/Apple Loops Index w/out this directory you cannot use the Loop Browser. Then I get this message...
Instrument Library Invalid

Any solutions?

Is this a new installation of GarageBand or has it worked before on the same computer?
Or have you transferrred your GarageBand from a different computer?
The error message is saying, that your GarageBand installation is incomplete. There are essential foldrs missing in your system library.
Check, if indeed both folders are missing or if only the permissions are set incorrectly.
Your system library (the folder "System" directly on your system drive) should have the following folders inside the folder "Audio", and they need to be readable by the system and by administrators.
And in the folder /Library/Application Support there should be the Instrument Library.
If these folders do not exist (or no longer exist), restore them from your backup- If your GarageBand version is a new installation, the application may not hve been downloaded or installed completely, then reinstall GarageBand.
What is your GarageBAnd version, and how did you install it originally?
