How do I use the built-in audio input with AU Lab?

I just tried AU Lab for the first time, and I can't select an audio input.
The "Create New Document" window lets me choose "Built-in Output", but the pulldown for Input Source is greyed out. The area under the "Input" button says, "Audio Input Not Supported". How can it not support the built-in audio input? I even tried using SoundFlower to route the signal from the Line In (a small app) to the Input of AU Lab. AU Lab's display then shows two channels from Soundflower, but they are still greyed out.
All I want to do is get a signal from the built-in audio input routed to AU Lab so I can use AU effects to process the audio signal in real time. How do I do this?

They comes configured with your software. If you want to use, for example, Skype, you need to run the configuration wizard section.

How can I use the built-in Isight camera with an external camera (usb/firewire) at the same time?

How can I use the built-in Isight camera and an external video camera at the same time?
I'm wanting to stream over Oovoo/Skype/etc. using 2 cameras.
Thanks

Simple question with a not so simple answer.
(a) If you mean that you want to run multiple apps simultaneously using a different camera with each app, you may encounter computing power limitations. Digital video is processor intensive. The only way to know if your Mac can do this it to try it. If the video does not work together but each app works when it it the only app running, you are likely overloading your Mac's ability to process and/or move all the required data in your data bus. You can get a better indication of whether this is the case by watching your Activity Monitor utility while running the apps you want to use.
(b) If you mean that you want to have more than one compatible camera connected to your Mac simultaneously for ease of changing between video sources, some, but not necessarily all, apps you are using to operate your camera(s) allow you to select between your cameras.
How you select among connected cameras depends on which application you are using. Here is how camera selection works in a few examples:
(1) For iChat, you can choose which iSight you use in the "Camera:" choices bar in iChat > Preferences... > Audio/Video that appears when more than one compatible camera is connected. Although your camera choices will be different, the choices bar will look something similar to the Preferences settings shown here:
If you cannot see the "Camera" choices bar, your Mac is recognizing only one (or none) of your cameras. In that case, consider the suggestions fromhttp://support.apple.com/kb/HT2090 for iSight problems or refer to your other camera's documentation for help.
This particular choices bar solution applies ONLY to iChat. Most other applications also have settings that allow you to choose which camera to use. However, they do not all work the same way.
(2) For instance, iMovie HD's camera choice is NOT set via Preferences. When you have more than one compatible camera connected, iMovie6 HD uses a drop-down menu choice something like this (depending on which version of iMovie you use):
Note: Because I had no built-in iSight connected when I made this example, and because my external iSight was not connected, the drop-down menu showed only "Time Lapse." Because your Mac has a built-in iSight, your built-in iSight would show in the drop-down menu even when no other camera is connected. Connecting an additional Mac compatible webcam should allow you to choose either camera.
Other iMovie versions work slightly differently.
iMovie 9 (from iLife '11) uses a different camera choice button shown in this article:
http://docs.info.apple.com/article.html?path=iMovie/9.0/en/mov39f84285.html
iMovie 8 (from iLife '09) is slightly different as explained in this article:
http://docs.info.apple.com/article.html?path=iMovie/8.0/en/10172.html
In general, you can use your Mac's help for the application in use to find out how to select among more than one connected camera.
(3) Photo Booth in Snow Leopard 10.6.x and later uses the Photo Booth > Camera menu command to select which camera to use.
Note for readers with older Mac OS X: The previous version of Photo Booth that came with Tiger (10.4.x) is such a simple, basic app that it offers no menu selectable choice. Unless your built-in iSight is already occupied as the camera being used by some open application before you launch Photo Booth, Photo Booth will use ONLY your built-in iSight.
However, you can use the trick from ¶ 4 of http://docs.info.apple.com/article.html?artnum=302781 to let Photo Booth use an external camera.
(If you have an external Firewire camera connected, it may be used in preference to any USB webcam. If that is a problem for you, merely disconnect the problem Firewire device.)
(4) For FaceTime, launch the app and click the Video menu item.
If your Mac recognizes more than one connected compatible camera, a "Camera" section listing the cameras from which you can choose will appear there. Clicking on the desired camera name will let you select the one you want as shown in this image from my Mac Pro and LED Cinema Display:
If your Mac recognizes only one compatible camera, the "Camera" section will not appear in the Video menu, but FaceTime will automatically use the connected camera that is recognized by OS X.
(5) I do not use Skype oir Oovoo. For those or other apps, see Help for each app for info on how to select your desired camera.

Is there a reason why no one uses the built in audio inputs on the Mac?

I'm curious.... I've heard various things - but the sound did seem okay to me when I recorded straight into the Mac's input in the past. So... what is the problem with the Mac's inputs and outputs and why does everyone buy a sound card/device instead?

It seems rather odd that Mac fans generally take pride in owning high quality (expensive) machines but are happy ignore poor audio inputs and outputs.
It has nothing to do w/ taking pride in owning high quality machines - you don't buy the Mac because it has great Analog/Digital conversion (it doesn't). You buy a mac because of its stability, its out of the box compatibility with the two most proficient, professional DAWs out there (Pro Tools and Logic), its easy integration with most hardware, the way it handles audio processing. . . the list goes on and on and on. I don't really have the time to go into the intricacies of high quality audio processing, but NO COMPUTER has it. If a computer did come built in with Apogee master clocking, A/D/D/A conversion, and high quality analog mic preamps, you might be looking at your normal computer plus about $15,000 (at least.) Your machine is there for stabile, consistent, day to day recording and audio processing (whether it be editing, mixing, mastering or all three), and you purchase external audio interfaces for the dedicated function that they are made for.
With audio interfaces comes expandability and flexibility that NO system has right out of the box.

How do I use the built-in camera or webcam?

I know this may sound very elementary but there was no documentation with my Mac when I bought it new (except a thin flimsy pamphlet with very baic stuff in it) and the help menu comes up with nothing at all when I search for web cam, webcam or isight.
Where do I go to learn about how to use the built-in camera/web cam as a camera and also as a web cam?
Thank you

There should have been a seventy page booklet in the box with your new iMac. If yours is the latest version, clicking here will download it if you cannot find the physical copy. If yours is an older iMac model, you can search for the correct manual from the iNtel iMac Support Page > "Manuals" link.
After that, Mac 101 is a great web-based information source. If you don't need general help, take a look here for specifics about each application of interest.
VortexBoy wrote: ... and the help menu comes up with nothing at all when I search for web cam, webcam or isight....
If your posted info is correct that you are running Mac OS X (10.7.3), you should be able to get started by using your Mac's Finder > Help menu command. Searching for "camera" (without quotation marks) on my 10.7.3 Mac returns Mac's Help article entitled "Use your Mac’s built-in camera." This is the web version of the same help.
Other apps, like QuickTime Player (the Lion QT 10.x version), and iMovie (part of iLife that came with your Mac) can also use your iMac's camera.
iMovie Help or this web page version of the same help will explain how to "Record video directly into iMovie".
Use QTX Player's File > New Movie Recording menu command to record video with it. You can configure size and quality of the recorded material by using QTX's preferences as shown in this image:
VortexBoy wrote: ... Where do I go to learn about how to use the built-in camera/web cam as a camera and also as a web cam? ...
Different apps do not all work the same. For function-specific help, search Help in separate camera applications; i.e., after you launch Photo Booth, iChat, QTX, iChat, etc., use the individual app's Help menu command to search for more info on the camera or what you want to do.
This article offers great basic tips about how to position, light, and use built-in cameras. Although its subject shows it was written for iMacs, it is equally applicable to other reader's inbuilt Apple cameras, too.
For more specialized functions than those offered by the camera software already included with your Mac, you can search the Mac App Store for other apps that can use your camera.
For webcam help with iChat, use Apple's iChat Support page if you need more help that that provided in the dialog boxes and iChat > Help on your Mac.
To use your camera with FaceTime, search your Mac's FaceTime > Help or these web versions of the same Help topics that should be available on your Mac.
Skype or other third party webcam apps will offer their own Help menus of varying quality. In additon to these app Help services, some apps offer comprehensive Support services via their web page. If you decide to add Skype to your Mac, you can click here to review the excellent Skype Support pages.
If you need to start a new topic for specific questions after you get started, give as much detail about what you want to do and what you may have already tried unsuccessfully. We will offer specific suggestions based on the details you provide.
Enjoy your new Mac!

How can i use the built-in microphone at the same time as using my earphones? (they have an external mic attached)

I am recording stuff on garageband and i need to hear other tracks as I'm playing, but I have to play them through external earphones so that the they don't overlap onto the one I'm creating.
The wire for my earphones has an external microphone attached to it, however, I have no desire to use this microphone as it is ridiculously sensitive and picks up even the slightest vibrations when the wires rub against my cheek or my t-shirt.
Therefore, I need to use the built-in microphone when recording. Except that, whenever I plug in the earphones to the iMac, garageband automatically switches to the external microphone. I went in to the Garageband preferences, and saw that it was set up for recording through the built-in mic, which is strange because input is clearly coming from the external.
So, I went into the iMac System preferences > sound > input. There are three options here: Internal microphone, Line-in, and Soundbooth 3.0.
What I found is that whenever I plug my earphones into the iMac, the option for 'Internal microphone' changes into an option for 'external microphone'. Now, I am fairly sure that an 'external microphone' is EXACTLY the same thing as a 'Line-in', but I'm not so sure now, so please feel free to correct me if I am wrong.
How do I stop the iMac from changing 'Internal microphone' to 'External microphone'? It is very important that I am able use the earphones and the Built-in Mic at the same time.

Hi John,
I think the only way is to get an iMic...

How do I use the built-in microphone on my iMac while using Windows XP?

My iMac has a built-in microphone. My computer is set up with a partition to run either mac or windows. I would like to use the built-in microphone feature when I am using Windows XP. Is there any way that I can do this?

Hi and welcome to Discussions,
assuming you have installed the neccessary BootCamp Drivers from the OSX Leopard DVD the internal mic is useable with any kind of recording software.
Windows itself has a rather rudimentary Audiorecorder program built-in.
For a more sophisticated recording program have a look at Audacity http://audacity.sourceforge.net/

How do I use the front panel audio/video jacks?

I have a Pavilion HPE-480t desktop and can't find documentation anywhere on how to use the front autio/video jacks. When I hook up a device no software automatically loads. Is there a supplied program that recognizes them?
This question was solved.
View Solution.

Hi,
Based on this, your machine can have ONE of the following combinations at the front, I use the last one to answer your question:
15-in-1 card reader + 1394 + 2 USB + 1 headphone jack + 1 microphone jack
15-in-1 card reader + HP USB 3.0 SuperSpeed PCIe x1 card + 1394 + 2 USB + 1 headphone jack + 1 microphone jack
15-in-1 card reader + 1394 + 2 USB + 1 headphone jack + 1 microphone jack + Audio L/R + S-video + Composite Video
15-in-1 card reader + HP USB 3.0 SuperSpeed PCIe x1 card + 1394 + 2 USB + 1 headphone jack + 1 microphone jack + Audio L/R + S-video + Composite Video
Card reader: you can use it to read memory cards (normally from digital cameras or video cameras).
USB3: newer USB port(s) which can run 10 times faster than USB2
1394 or Firewire port: also normally for video cameras, many machines do not have it now
USB: normal USB 2 ports
Headphone jack: for headphone, earphone or external speakers
Microphone jack: For a microphone
Audio L/R: color coded for left and right audio channels, it does not say in or out.
S-video: Connect to additional monitor/TV, Many modern monitors/TV's now do NOT use this port.
Composite Video: also color coded (yellow). Connect to additional monitor/TV, Many modern monitors/TV's now do NOT use this port.

How do I use the event.target.name String with an external dispatchEvent?

...I hope the title question makes sense...
On my stage I have an externally loaded SWF with a button. When clicked the button dispatches an event to the main stage.
On the main stage a listener then loads an SWF into a loader called gallery.
The gallery loader is also being shared by buttons on the main stage which use the event.target.name String to call in SWFs with corresponding names.
I am using Tweens to fade-out and -in content to the gallery when a button is pressed.
Loading the SWFs was working until I tried to create a universal button function for the dispatchEvent buttons...
The problem I have is that I don't know how to define the String to tell the newSWFRequest where to find the SWF when triggered by the external buttons.
(I may be doing this all wrong... but figured the best way to load an SWF on to the main stage from an external SWF was by using dispatchEvent??)
My code triggers the Event and the gallery loader fades out, but then it cannot find the new SWF:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
Please can someone help me understand the way to make the String point in the right direction? (I think the only errors are in bold below)
Code:
var myTweenIn2:Tween;
var myTweenOut2:Tween;
var nextLoadS2:String;
// Listen for external event dispatched from external btns
addEventListener("contactStage", btnClickExtrnl);
function btnClickExtrnl(e:Event):void {
nextLoadS2 = ?????
myTweenOut2=new Tween(gallery,"alpha",None.easeOut,gallery.alpha,0,0.2,true);
myTweenOut2.addEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteF2);
// Btns Universal function
function tweenOutCompleteF2(e:TweenEvent){
myTweenOut2.removeEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteF2);
myTweenOut2=null;
    var newSWFRequest:URLRequest = new URLRequest("swfs/" + nextLoadS2 + ".swf");
myTweenIn2 = new Tween(gallery, "alpha", None.easeOut, gallery.alpha, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
Thank you.

That works – thank you!
I'm now using this code to fade in each of the SWFs:
function contactStage(e:MouseEvent):void {
    var newSWFRequest:URLRequest = new URLRequest("swfs/"+e.currentTarget.name+".swf");
    myTweenIn = new Tween(gallery, "alpha", None.easeOut, 0, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
But I cannot add the fade out function. I have amended the above code to create:
var myTweenOutX:Tween;
var myTweenInX:Tween;
function contactStage(e:MouseEvent):void {
myTweenOutX=new Tween(gallery,"alpha",None.easeOut,gallery.alpha,0,0.2,true);
myTweenOutX.addEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteFX);
function tweenOutCompleteFX(e:TweenEvent){
myTweenOutX.removeEventListener(TweenEvent.MOTION_FINISH,tweenOutCompleteFX);
myTweenOutX=null;
    var newSWFRequest:URLRequest = new URLRequest("swfs/"+e.currentTarget.name+".swf");
myTweenInX = new Tween(gallery, "alpha", None.easeOut, 0, 1, 0.2, true);
    gallery.load(newSWFRequest);
    gallery.x = Xpos;
    gallery.y = Ypos;
But get this error:
ReferenceError: Error #1069: Property name not found on fl.transitions.Tween and there is no default value.
at ACOUSTIC_fla::MainTimeline/tweenOutCompleteFX()[ACOUSTIC_fla.MainTimeline::frame1:110]

How do I use the High Speed Data Logger with multiple I/O devices?

I am using the High Speed Data Logger vi to read from a 16 channel A/D card (NI PCI-MIO-16E). The project may require more than 16 channels. How can I use High Speed Data Logger to read from two A/D cards? Will it be able to write the data to one file?

The High Speed Data Logger vi will not acquire and right to multiple DAQ boards at the same time without modification. LabVIEW is more than capable of doing this what you are trying to do, but you will have to modify the code.

How do I use the Index Values property node with a multidimensional array.

I am using a 2D array to store operator inputs on my front panel. I only want to display one element to the operator at a time. I am trying to use the Index Values property node to change the displayed element. However, I can only get the Rows index to work. How do I direct the Columns index as well? The help says to use one per dimension. I need clarification on what this is talking about. I've tried adding a second element to the property node, 2 seperate property nodes, and diferent wiring techniques. (series, parallel)

If you only wire up one of the inputs (col or row) what you get out is a 1D array of either the column or row. If you wire controls to both, then you will get one element out of the array. Getting a single element in a 2D array requires you to specify both a row and column.

Bought a macbook, how can I use the built-in isight?

Would anyone be able to give me advice on the above matter? As far as I found out I can take pics in photobooth, but are there other possibilities with the camera? I heard that you can videotape yourself also? (I am about to take an oral exam so I thought a little practice and see the presentation myself would help..)
Thank you in advance and have a good weekend!
