Dual Audio Streams

Is there a way to have two audio streams playing at the same time on the iPad and/or iPhone? I'm looking for a workaround specifically with Spotify playing music while watching a workout video streaming from iTunes. Thanks!

ATV3 6.1.1 Home Sharing M4V AAC/AC3 dual audio stream

Guys I have a brand new ATV3 on 6.1.1
Home Sharing enabled
iTunes Library with x264 m4v's with 2 audio streams -> AAC/AC3
On ATV2 Home Sharing defaults to the AC3 Dolby stream and 5.1 is enabled for home sharing
ATV3 I have to toggle from AC3 to AAC and back to get it to work....
The AC3 stream is active when launching the film, but there is no sound unless i toggle to AAC then back to AC3
I have tried HDMI as well as optical audio.
Dolby in settings is set to on.
Anyone run into this?

Edit...
ATV2 Works.. Home Sharing connecting to the M4Vs in iTunes that have the dual audio streams (AAC/AC3) automatically detects the AC3 stream and it plays fine wit Dolby 5.1
ATV3 Home sharing connections to the M4Vs in iTunes with the same dual streams. It detects the AC3, but does NOT play it. SILENCE. BUT, if I toggle the stream in ATV with the remote and select the AAC, I get PCM and it works. Toggle back to AC3, I get Dolby and it works.
Does anyone know why it doesnt work from the beginning and why I have to toggle this?

Rip video with secondary/dual audio stream from dvd to ipod

I see that my 160gb ipod has an option in the video section for secondary audio. I assume this means a video file or .mp4 can be created with 2 different audio tracks. I want to be able to have a video file with the standard audio and commentary track. I have searched online and I have seen a couple of sites that claim their software can do that but the demos Ive tried havent worked. Does anyone have any experience in this? Or does anyone know of the definitive program to use?

i just downloaded this program, but when i pop in a dvd, it won't open up. do i have to be registered in order for this to work properly?

Dual Audio Outs? / HDMI and RCA Analog at the same time?

I am trying to figure out if the Apple TV supports dual audio output. My Onkyo receiver supports dual-room/dual-source audio (powered and line-level stereo audio output for 2nd room). The problem is it can only accept an analog source for the second room.
I know that HDMI takes precedence over component video connections if both are connected.
Will the ATV send audio signal out of the HDMI and RCA Analog jacks at the same time so I can enjoy streaming music is two rooms simultaneously?

I like to be a helpful soul, so I decided to pull the owner's manual from Onkyo and take a look at the receiver, without ever thinking about the model number, and come to find out, I have my Apple TV hooked into an Onkyo TX-SR606.
I appreciate that!

Problem is, I have the HDMI into the Onkyo and the analog outs going to to another stereo receiver for the outdoor speakers. Both work at the same time, which means that the Apple TV will output both digital and analog at the same time.
Good to know.
Iowabeerguy wrote:
Now, let's look at the receiver - if you have the HDMI plugged into the - say DVD input, and it's playing through the main system, and you plug the analog outputs into the DVD analog in on the receiver, the Zone 2 out will automatically look at the HDMI input, and not put out anything to the Zone 2 outs, because it won't pass digital to the Zone 2 outs.
Oh yeah, that makes sense!
Iowabeerguy wrote:
I can't try it tonight, but I think if you plug the analog outputs from the Apple TV to an input that isn't assigned to an HDMI in, (like CD) and then set the Zone 2 amp to play that source, it should work.
I've set aside some "tinkering" time this weekend to try that. I'll let you know if it works; I think it will. Thanks again!

Audio streaming in client - server - client model

Hi we are developing an application which contains audio chat. all Clients are connected to the server using a plain socket. The message is done through server. No client is in public ip(i.e. no two clients will connect each other directly they have to go through the server only).
We are incorporating audio chat in this scenario using JMF. But the problem is no client is in public ip. We are able to send the audio stream to the server by using JMF but how to send this stream to the other clients using a socket.
Please suggest some solution to this problem.
Thanks in advance.

Checkout Rogue Amoeba's 'Nicecast', looks like it would do what you want:

GX740 - Anyone get two TRUE separate audio streams out Headphones and LINE OUT?

Hoping for an update on this. I asked MSI via their support section and wow... what a FAIL that was:
Quote
Do you have new specific drivers that allow TRUE 4 channel output? 2 out the headphones and 2 separate out the LINE OUT as implied by the design? I've tried everything and it doesn't work.
I've tried ASIO4YOU drivers - doesn't work.
I've tried every RealTek driver out there - nothing.
Yes, I've set the RealTek driver to do multiple out but it sends the audio out the HDMI port, NOT THE LINE!
I know this can be done cause you can set the REALTEK for 7.1 and you get separate streams out the headphones and line-out ports!
Please - you've sold a laptop with "Headphone Out" and "Line Out" yet it fails to actually do that - NEW DRIVERS PLEASE?

Dear Customer,
Please go to msi global website to download the audio driver,then install it.
audio driver:
http://www.msi.com/service/download/nbdriver-15227.html
Needless to say, that did nothing. In fact, I can't understand how I could of received such an answer given it made no sense what-so-ever. Download the driver that came with it? One that's now almost a year old?
Regardless... I've tried that one. I've tried the latest RealTek drivers. I've tried a multitude of ASIO drivers. NOTHING WORKS. Yes, I've set the RealTek to send TWO SEPARATE STREAMS. That does NOTHING. The only thing I've been able to ascertain is that you can send one stream out the headphone/line out (same thing) AND one out the HD port which is useless.
Here's the pain in the ass: If you go to the RealTek setup and change it to 7.1 and hit TEST, you DO hear separate output out the HEADPHONE JACK and the THIRD Audio Out jack which is the side fills so I know this laptop CAN spit audio out two separate outputs sitting on the side of the computer.
Why do I want to do this:
Simple. I'm lugging around an external audio interface for DJing and it's a pain. I'd rather just tap the headphones out for, well, headphones and send the line out or that third audio output to the DJ mixer. Done! I've tried MIXMEISTER, VIRTUAL DJ, NOTHING WORKS! I can select various strangely named outputs insinuating speaker out, speaker out + 1, etc... but no... it doesn't work at all...
Sooooooooo... has ANYONE been able to get this to work? I'd love to know...

Yea Stu... been through this part... Playback devices show the typical:
1. Speakers (Realtek) -> Plays on ext. speakers but sounds like just treble. Headphone Out plays this stream.
2. RealTek HD Audio 2nd output -> Plays on ext. speakers but sounds like bass/mids. No treble. NO OUTPUT PLAYS THIS. Plug anything in and sound from the speakers just shuts off
3. Realtek HDMI Output (Not selectable)
4. Realtek Digital Output (Not selectable)
So yea, it seems right out of the box there is a problem with the sound on this unit. Choosing speakers sounds like crap (no mid/bass) and choosing HD Audio 2nd output sounds like crap (all mid/bass no treble).
There is no discrete dual audio out the jacks.
HOWEVER - Go choose 7.1 from the realtek setup and do a test. Well what do you know, DISCRETE 2ND AUDIO OUTPUT OUT THE HEADPHONE JACK AND THE 3RD OUTPUT JACK OF THE 4 IN A ROW. This PROVES you can have two discrete stereo audio streams coming out the output jacks. Just need someone to write the driver for it.
Here's the thing. This laptop HAS 4 1/8" JACKS. SEE:
Here's what the manual says about the output jacks:

Compressor stops working at audio stream

I've been having some Compressor problems, which I think I have narrowed down, at least in this one instance to a corrupt audio file. I submitted an hour long self contained QT movie 2 nights ago, and it successfully encoded the MPEG 2 file, but stopped when it came to the ac3 file. I de & re-installed Compressor from the original FCP 2 discs, so I'm now running 3.0, on OS 10.4.11, on a G5 dual 1.8 machine.
So last night I submitted the same QT movie that had stopped compressing the night before, and it did the same thing again- successfully encoded the video stream, but NOT the audio. Compressor stopped working in exactly in the same place as it did the night before. This morning I used Jon Chappell's app Compressor Repair, and am up and running again, compressing another movie that seems to be working just fine.
But, I still have the problem with the particular movie with bad audio file. From another forum, someone had a similiar problem 3 years ago with a corrupted audio file. Which I think is what my problem is now, for at least one video I'm trying to encode.
So the questions are: How do you find the corrupted file, what do you do? How can I encode the audio stream for this file?
Of course I have a deadline for Monday, so any suggestions are most welcomed!
Thanks very much
Melinda

Try exporting a self contained QT movie which only includes the audio from your sequence. Set it to be "current settings"... will then match your sequence settings. If it exports OK, just put this file in the sequence for compression.
Micheal's solution is much the same actually as mine... When you use the sequence settings, the QT is nothing more than a QT movie wrap around the aiff.
QT is a container for media files of any kind actually.

Can I deal with the audio stream while recording?How?

Hi, All,
I am doing a project about SIP phone using J2ME. I am quite new to this area. I want to mask the audio stream before it sends out. I want to know if it can be achieved in J2Me. if yes, would you give me some reference? Thanks for any reply.

Is anyone who knows how to achieve this？

I want to be able to use airplay to stream audio to another iOS device, and then use that audio stream to be used when recording video instead of the built in microphone / microphone input. Is this possible?

I want to be able to use airplay to stream audio to another iOS device, and then use that audio stream to be used when recording video instead of the built in microphone / microphone input. Is this possible?

A third-party app probably cannot obtain a stream from another app. To the best of my knowledge, such a capability is not provided in the software development kit, apps being "sandboxed" from each other and so allowed to communicate only in very specific and limited ways.
I'm not completely sure what you mean by "limitations on video capture". An iPhone, to the best of my knowledge, can natively record video only through it's built-in camera, and audio while doing video recording only through the built-in microphone or mic/headphone jack. There might be a video recording app that would allow audio input from an external device connected to the dock connector, but I'm not sure.
Regards.

Can I use the new Apple TV without a display for audio streaming only?

Here's my situation...
I have an Airport Express in my living room connected to my DSL modem to create a wifi network. I also have a current model MacBook Pro and would like to add an Apple TV to my bedroom system for music and Netflix audio streaming. I do not own a TV to do any setup.
If I bought an ATV for my bedroom and connected the optical output to my DAC, would I be able to accomplish my goal or is there a setup procedure on the ATV which mandates a display?
I realize I could just buy another Airport Express for easy audio streaming, but then I wouldn't have the Netflix audio capability which I would like since I watch movies on my MBP. I'm hoping like an Airport Express, the ATV would configure itself for audio streaming once connected to my wifi network.
Thanks for any help or ideas.

If you're planning to stream from iTunes to the AppleTV controlling the material via iTunes, I suspect it may just appear as an Airtunes speaker option for iTunes without any setup needed.
No Netflix in UK so don't know much about it, but I suspect you'd need to control the AppleTV directly for this unless you were viewing on the MBP and used something like Rogue Amoeba's Airfoil to transmit audio.
If you have no desire for controlling AppleTV either on an TV or using Remote app for iPhone etc (and you'd need to set AppleTV up with a TV for Netflix or AppleTV controlled streaming anyway), you might want to consider using another Express upstairs and hook it's optical out to your DAC if you're just after stereo audio.

How do I stream music from non-iTunes apps to Airport (mac air core-i7 OS 10.7.5 airport firmware 7.6.1 --- option-clicking speaker icon only shows internal speakers - audio streaming works from iTunes just fine.

Hello Achates:
I did not read the rather long post. If you wish to reinstall OS X 10.4, use your software install DVD. Backup is essential. To minimize your risk, I would use an archive and install:
http://docs.info.apple.com/article.html?artnum=107120
In that way, you will have a fresh copy of OS X and your current settings will be preserved.
Incidentally, I do not agree that the printer problem is best solved by reinstalling OS X. I have had HP printers for sometime and, on one occasion, had difficulty after an upgrade. HP technical support walked me through uninstalling all traces of the HP driver and then reinstalling.

Error encountered while copying audio stream

In Captivate 4, I attempt to capture screens. I hear the clicking as it captures, I click END when finished. Program attempts to save and then a dialog box displays with "error encountered while copying audio stream". I am not attempting to record any audio.
I searched the web and found references to this error back two versions and two years - but no solution.
Does anyone know of a solution? Thanks.

Hi there,
I have experienced this on Windows XP. In my case this was due to a dll (Dynamic Link Library) file not being corectly registered in the Windows XP Registry. If you are using XP then take a look at the following blog post.

Audio Stream Recorder - Error: Audio device is already being used by another prog

I realized that Audio Stream Recorder is does not "work" through server list feature. So I am simply trying to use the manual method of adding URL's to the interface. However regardless of the type of stream, shoutcast, windows media or real audio, I receive the error "audio device is already being used by another program". Does anyone know how to fix this? I have closed my audio application etc to no avail. <RANT WARNING> I was very excited about using this application when I read about it. However an application that provides none of the stated features is not an application, its false advertising, since it clearly states on the box, help files and website this products "features". Anyway, it'ss very disappointing. Also, does anyone know what the supported steaming formats are, the help file say the application requires RealONE and Windows Media Player but does not mention audio stream formats? Thanks you in advance for any help.

I have the same issue. I updated to the latest software, to no avail. My first suspicion is that some Microsoft patch caused this, but I cannot verify this.
Apparently no one at Creative is very interested in this issue.

IPhone 4S and iPhone 5 Running iOS 6.0.1 and A2DP audio streaming on a 2012 Lexus RX350 (Factory Car Stereo)

Hello Everyone,
Before the release of iOS6 and the iPhone 5, I was able to use the A2DP audio streaming on my car no problems and I was really a happy camper, when upgraded my iPhone 4S to the iPhone 5 (Which came already with iOS6) that funtionality did not work any more, I reconnected my iPhone 4s running iOS 5.1.1 and worked like a charm, then I thought my brand new iPhone has bluetooth problem , that same night (Release data iPhone 5 and iOS 6), I update my iPhone 4S and prepare it to give it to my wife, then It occured to me to go and test the phone back on the car but now Running iOS 6 and "viola", the phone did not stream audio via A2DP. So yesterday Apple Release a minor update for iOS (6.0.1) and after reading the release notes (which it did not say anything Bluetooth enhancements) and updating my iPhone, went and try to test again the phone and did not work. (No A2DP audio streaming), Definatelly there is a problem, I called iOS Tech support and open a Case. Here are the screenshots for the iphone and car stereo.
Iphone:
Car Stereo:
Phone (Voice Feature) works fine with the car.
This happens when trying to Connect the phone manually.
If anyone had this problem in the past and solved, please let us know.
Thanks
Rommel J. Jimenez

I had this problem with my iPhone 4 after upgrading to ios 6.0 (10A403). I called apple support and was given a fix for my problem. The Apple support rep had me do a reset on my Iphone. The iPhone then worked with streaming music through bluetooth to my Lexus and also now works with the usb tether. I did not have to delete the pairing, but that certainly wont hurt.
