IDT High Definition Audio CODEC VERSION: 1.0.5934.0 (Very Very Urgent)

Hi All,
I am looking for below driver @windows xp sp3 OS or any compitable sound driver for windows xp sp3. I have hp dvd41114nr laptop and i have downgrade to xp but i am missing sound driver.
IDT High Definition Audio CODEC VERSION: 1.0.5934.0
Thanks

Really try the link and follow the directions. This stuff works. Jus tdo it correctly. You have to move the stac file to the correct folder and have the installer handle the installation of the hardware. But trust me it is extremely important to follow them step by step. I am using these drivers and if you really need help maybe you should hook up sometime and I will just send you my plain bare installation of this Windows XP Installer. I have a open license, and a OEM setup. I'll share the Open license copy which will require you to produce your own key. Don't ask me for the OEM because it's illegal and second it will require my BIOS to work. Your not getitn my BIOS LOL!!!
It's not just just a computer, it is what YOU want!!!!

Audio codecs problem

i make an application that transfer audio data across networks
i did capture the sound and send it and play it again well using jmf and also using data source and target line
but the problem that i have to use lossless codec to encode and decode it
first i need advice which one is better ?
i tried to use jspeex and jflac
in jspeex found alot of exceptions
and in jflac decode seems it will work well in FLACDecoder
but can't find how to encode in FLACEncoder
http://jflac.sourceforge.net/apidocs/index.html
please help me, thank u

Either of those codecs are supported by JMF. And I have no idea what forum to go to to learn about which codecs are best, but neither of those are JMF-supported codecs so unless you have plans to implement them into JMF, this is again not the forum to ask that question on. Looks like you'd need to go to a sourceforge forum to learn about JFLAC.
As the second part of your question, the best lossless encoding, it depends on how you define "best"...
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/formats.html#RTPFormats]
There's the list of RTP formats that JMF supports. As you can see, there isn't a big selection of RTP audio formats... and none of them are "lossless" if you're coming from a higher-quality signal.

I am using iMac OS 10.7.2 with Garageband'11 6.0.4. I can't record sound from mixer Behringer X1622USB using USB out. when I connect the mixer to iMac via USB appears USB Audio CODEC on Sound and Preferences but I can't get no sound from mixer to iMac only sound from iMac to mixer. I only can record sound using microphone line in. Please help.

Eric,
Thanks for your reply. Realtek audio works only in playback. There is a stereo mix in the mixer but the recording controls are not operable with no sliders in the mixer for any recording option. Slider controls appear to be grayed out. Can't figure out how to enable them. Downloaded newest drivers to no avail.
The M Audio control panel has no apparent option for recording stereo mix. Adobe ignores the sound from the DVD or CD and shows flatline.
I'm trying to record the sound from the DVD not rip the track.
When I go to Audio Driver Setup and select Audition 3.0 windows sound, there is no input device installed.
I'm thinking of going back to a decent internal Soundblaster card like I have on my 8 year old machine I am replacing.

Dubbing Audio with ASUS P6T WS Pro motherboard ADI AD2000B Audio CODEC

I am trying to dub audio commentary into my clips using the SoundMAX program settings provided with the ASUS ADI AD2000B Audio Codec. I have confirmed a microphone signal appears in SoundMAX and that PPro Audio Hardware Settings/Enable Devices has a check mark against 'Microphone(SoundMAX Integrated'. The other unchecked device shown is 'Line In (SoundMAX Intergrated Di'. When I set up the Audio Mixer with a mono Audio 4 channel, click the Audio 4 microphone icon to turn it on, turn off all other audio channels, click the record button, then speak into the microphone, no signal appears. Unfortunately, I have not been able to confirm that I am providing ASIO audio to PPro. I need to know if I am wasting my time trying to dub audio with the present setup or I am missing something. If no ASIO is possible using the present setup, what audio card do you recommend?

When you have your Mic input enabled in ASIO hardware setup, then in the audio mixer ou need to arm tracks with mic inputs then, then press the record button the input should be seen at this point. But to record you voice over onto time line you need to play the timeline. So that the targeted Audio Track will be recorded onto timeline. And after you stop playback you will se recorded audio.
Good luck.

Does version 12 support producing video clip with AMR audio codec?

From some documents i used as reference to proceude some videos for my phone Premiere Elements 8 can produce video clips with AMR audio codec. I bought today the Premiere elements 12 but I can not find a way to set AMR audio codec for my video clip. Only AAC audio codec seems available. Is it possible to add AMR codec to 12 version?

Neurona17
Adobe typically supports only current version, and, if you purchased from it, is strict on "within 30 days of purchase": for money back on that current version purchase. I do not believe such a thing as a "change the license for other earlier release such as 8 or 9" exists at Adobe. But, you could ask. If you wish to purchase one of those earlier versions that supports AMR export, you might still find some online.
Is the before import conversion of AMR to WAV a viable alternative?
You wrote
Unfortunately so far I have not been able to generate any useful video clip for my system with this 12 version.
Is this in regard to the AMR requirement or to any video without the AMR audio?
Online I have seen that there is a download for the AMR audio codec. Does your system now show that you have such a codec installed on your computer. If not, I am not sure if download of this codec would place it in the Premiere Elements Publish+Share export settings choices, similar to import of some .avi video codecs. (Sometimes 3rd party codecs can create problem, so proceed with caution if you pursue that AMR audio codec idea.
Please update us on your progress when you get a chance.
Thanks.

USB Audio Codec DEMO driver

Good afternoon. Today I bought a mixer Allen & Heath Xone 42. I am having problems connecting the mixer to my laptop. I use Mac Os Lion 10.7.4. When you connect the system uses the USB Audio Codec DEMO driver. Sound enters the mixer, but is accompanied by a constant beep. Every 30 seconds. This is the way and makes the mixer unfit for entry. Please help me resolve this issue.
on the Internet found several similar complaints. Advised to remove the codec. But how to do it, I do not understand.
In support of Allen & Heath wrote the following:
Mac Pro, Mac OS X (10.7.4)

But this mic is for Mac too. It's says that you "plug and play". I bought this microphone to record my music work at home.
This is the website, It says that works fine with Garage Band but ...

USB Audio CODEC not being recognised.

Hello,
I have my my Wharfedale 802 mixer plugged into my MAC Mini (late 2012), Processor - 2.5 GHz Intel Core i5, Memory - 4 GB 1600 MHz DDR3, via USB however it is not being recognised as USB audio CODEC what so ever. I have also tried searching for this to set the outputs in Logic and it is not recognised there either.
I have just updated my iOS to Yosemite 10.10.2 and also my Logic X does anybody know why my mac is not recognising my USB audio CODEC for an input or output?
Please help.
Thanks

I just posted this problem I had also. The USB audio Codec is for PPC macs only. I couldnt get a PYLE USB cassette deck to work in AUDACITY because it needed that codec.Windows users use this codec for many devices including the one you are trying to connect.
My post in Snow leopard forum:
I have come to the conclusion that this codec only worked on Macs that used PPC chips,not Intel Macs.Apple must have dropped it when switching to Intel.No where on the net can I find anything about this codec on newer mac OS's and newer Macs.
Judging from this user's comment and others,they are working with OSX10.4 or newer OS that has PPC support like the first Mac Pro and other PPC's.I think the comments below answer my own original question.Hope this helps anyone with the same kind of problem with USB devices that need USB audio CODEC.
In Audacity prefs, I selected:
"USB Audio CODEC" for both Input and playback.
I even tried lower sample rates and such. Record button stays grey and readouts don't show any input whatsoever even though I am sending a signal.
Mac is a 533Ghz g4 (Digitial audio) running 10.4.11
It is plug into a USB port on back of machine.

Mp4 converted video file is missing audio codec

I have several avi. files on my computer which were converted to mp4. using videora software. A few of these converted mp4. files then had no audio when I tried to play them on my Ipod. I am confused as to how to add the audio codec back into the video files. Do I have to install this to avi. then convert to mp4., or is there some audio codec which will apply directly to mp4. so they do not have to be reconverted? What is the procedure at this point? Thanks for your help in advance.

First thing to do is find out if Videora supports whatever audio codec the AVI uses.
If it supposedly does, write it off as one of the many bugs with videora and get a different transcoder that supports the audio codec.
Outside of having good knowledge of video production and the right tools-there is no easy way to do what you want.

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp56001-56500/sp56429.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and start the notebook.
Let Windows fully load - it will automatically load an audio driver, but just let it complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, restart the notebook again.

DP-K

Standard and good audio codec with Quicktimes?

I'm surprised to see there doesn't appear to be any documentation on the audio codecs available in Quicktime. I have no idea which one's are better than the others, nor what the difference between any of them are... nor even if they are all compatible with all other platforms, etc.
Could anyone let me know what is a safe (compatible with most/all platforms) and good (good compression and quality) for online quicktimes?
Audio doesn't have to be incredible... just 'good enough' for 300x200 pixel clips. Not looking for 'exact frequency responses', etc... Just something that doesn't sound like sizzling bacon.
Could someone tell me what their favorites are... and maybe some info on some of them? Right now, they are completely foreign to me.
Thanks...
(If it matters... WinXP Pro, Adobe Production Suite CS3)

Ya, it's bizarre.... AE has some features on its Render section, and some on it's export (....ex. You can only set Fast Start if you are exporting, not in the regular render area).
What I did since then is just render an uncompressed QT of the clip, and brought it into the standalone QT Pro player. As luck would have it, it allows AAC as an audio codec when doing an H.264 format clip. So, I'll try that out.
Ya, I was using IMA 4:1 previous to that... Seemed safe. Previous to THAT (up to a day or two ago), I was always using None, as I had no clue about any of the audio codecs, since the manual doesn't appear to make any mention of them.
I'm STILL trying to get my QTs to Fast Start... Something seriously wrong.... The HTML code AND the files SEEM to be fine, yet it still won't do it.... (although it did do it once or twice, but not since, while I was testing yesterday).
I'm trying exporting completely out of the standalone QT Pro player... I suspect something is fishy with AE's Fast Start encoding. Should work 'out of the box'... No idea why it's not....

Can I change audio codec when convert flv to mov ?

I just get Total Video Converter from App store to convert my downloaded flv to mov. My question is how can I change the audio codec to ac3, aac, or mp3?
Below is its screenshot:

A simple problem, I think you are beginner to this app. In the tool bar, you can find a button "Settings", click it, you will get a window named "Options", and there are 4 tabs: "Video", "Audio", "Resize", "Crop&Pad", and "Audio" tab is the right you need like below:
There, you can set your desired audio codec with option "Audio Codec"
Hope this can help you. Good luck.

The reason for the message: sometimes JMF just gets it wrong.
See
http://forum.java.sun.com/thread.jsp?forum=28&thread=348888
But I think a good test is:
Try playing your *.mp3 in JMStudio . Also, you can just use JMStudio to the listening address and you will get the same error.
