Problem using external mic with imovie

My internal mic does not work; Ihave bought a logitech external mic that shows up as working but imovie does not record my voice.

Save the files that you want on the external hard drive to a data DVD or CD and then reformat.

Audio problems using external mic

Hi,
I'm having problems hearing audio that was recorded using an external mic - both wireless and wired handhelds.
I can hear the audio through the camera (Canon GL2 dv)
but not during importing into IMovie HD 5.02.
After import I still can't hear audio. All volumes are up and on and boxes are checked. Is there an audio patch?
Please help!

Hi Sue,
No that didn't solve the problem either.
It seems to be a problem with IMovie.
You can hear the audio using Final Cut Pro.

Problem using external drive with hdiutil

Hello,
I use hdiutil to produce CDR masters for our educational software. Works great if I only use my built in CD-RW/DVD-ROM drive on my 15" AL PowerBook. But it won't recognize my external LaCie 1394 CDRW firewire 400 drive. The -anydevice option has no effect. But if I insert a blank CDR, the Finder recognizes it and asks what to do. I've tried the -device option with the device name and still no joy. This is on 10.3.9, so I repeated the tests on 10.4.6 with no luck. The 10.4 Finder also regnizes the device. I've tried hdiutil burn -list and the firewire drive shows up as DRDeviceSupportLevelAppleSupported.
Any ideas?
Cole

It seems you need to include "IOService:" in front of the OF path.
On my iMac (10.4):
imac$ hdiutil burn -list
PIONEER DVD-RW DVR-K06 via ATAPI (DRDeviceSupportLevelAppleShipping)
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PATA@1F,1/AppleIntelPIIX ATARoot/PRID@0/AppleIntelPIIXPATA/ATADeviceNub@0/IOATAPIProtocolTransport/IOSCSI PeripheralDeviceNub/IOSCSIPeripheralDeviceType05/IODVDServices
and the following seems to work:
imac$ hdiutil burn test.dmg -device IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PATA@1F,1/AppleIntelPIIX ATARoot/PRID@0/AppleIntelPIIXPATA/ATADeviceNub@0/IOATAPIProtocolTransport/IOSCSI PeripheralDeviceNub/IOSCSIPeripheralDeviceType05/IODVDServices -sizequery
On 10.3 you may need to add "-anydrive" option.

Using external mic with iMac 27 i7 under bootcamp with Windows 7

Hi,
I've recently got myself an iMac 27" with the i7 upgrade. I'm running Windows 7 Professional 32bit for gaming (Snow Leopard for everything else). I have a headset with two 3.5mm plugs, one for the headphones, one for the mic. I can't get the mic to work (headphones work fine though). I plug it into the line in port (as it's the only other port when the headphones are plugged in) but this doesn't work.
Does anyone know how to get this to work?
I read somewhere that the headphone port on the iMac is a "triband" port, so would work with the headphones provided with the iphone that have 3 bands on it (stereo sound and mic) or something similar...

Two things to try, first make sure your Win7 disk is spotlessly clean, my superdrive regularly spits out even slight smudges. then if that doesn't clear it up here is a maintenance tip with the reset:
As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Using an external drive with iMovie HD

I just received and formatted my external drive. At first I chose Mac OS Extended (Journaled) and Zero out data. When I got info (⌘+I) of the drive afterwards, it had 79 MB being used, journalling? So I then Erased it and chose Mac OS Extended and now it shows 59 MB as being used, whatever for IDK.
Does it matter which format I use for working with iMovie, journaled or not?
In the Get Info window there is an Ignore Ownership option. I know it doesn't need to be ticked when an OS is going to be loaded on the drive but am wondering if I should tick it since the drive is only going to be used mainly for iMovie projects and no OS is going to be loaded.
Should I tick Ownership or leave it off?
I have iMovie projects that have not been edited yet and a iDVD project on my internal drive.
Can I just drag and drop or copy and paste the iMovie projects to the external drives icon and delete the project from my internal drive to create a little more space? Is it simple as that?
Same thing with the iDVD project after archiving it first? Copy/Paste,Drag/Drop and delete.
I've got a backup drive but use SuperDuper! so I don't have any experience with using 'scratch?' drives.
I've read elsewhere on this Discussion site that the finished iMovie projects need to be on the internal drive in order to transfer to and edit in iDVD.
How and where do I move the project to from the external? Drag/Drop or Copy/Paste to my Desktop then Drag/Drop, Copy/Paste to iDVD, or some other way?
Thanks.

I am not sure zeroing out data on a SATA drives "marks" bad blocks/sectors. I think this may have only been on SCSI drives. I couldn't find a reference that it behaves this way on a SATA drive. Thus the only advantage being that it more securely erases files.
The click and hold works the same on a PB!

Distorted Tempo Using External Mic

Hello,
I've been trying to record my electric guitar using an external mic with a USB attachment, but whenever I record in Garageband, the tempo is always slightly distorted. It's not that I'm playing off tempo because I recorded the same attempts with a tape player and the results have been fine. Has anyone else had this problem or know how to solve it?

Go to GB help and type in quantize, you read about your issue there.
Good luck

Problem using SQL Loader with ODI

Hi,
I am having problems using SQL Loader with ODI. I am trying to fill an oracle table with data from a txt file. At first I had used "File to SQL" LKM, but due to the size of the source txt file (700MB), I decided to use "File to Oracle (SQLLDR)" LKM.
The error that appears in myFile.txt.log is: "SQL*Loader-101: Invalid argument for username/password"
I think that the problem could be in the definition of the data server (Physical architecutre in topology), because I have left blank Host, user and password.
Is this the problem? What host and user should I use? With "File to SQL" works fine living this blank, but takes to much time.
Thanks in advance

Problem using CORBA clients with RMI/EJB servers..!!!???

Hi,
I have a question on using EJB / or RMI servers with CORBA clients using
RMI-IIOP transport, which in theory should work, but in practice has few
glitches.
Basically, I have implemented a very simple server, StockTreader, which
looks up for a symbol and returns a 'Stock' object. In the first example, I
simplified the 'Stock' object to be a mere java.lang.String, so that lookup
would simply return the 'synbol'.
Then I have implemented the above, as an RMI-IIOP server (case 1) and a
CORBA server (case 2) with respective clients, and the pair of
client-servers work fine as long as they are CORBA-to-CORBA and RMI-to-RMI.
But the problem arises when I tried using the RMI server (via IIOP) with the
CORBA client, when the client tries to narrow the object ref obtained from
the naming service into the CORBA idl defined type (StockTrader) it ends up
with a class cast exception.
This is what I did to achieve the above results:
[1] Define an RMI interface StockTrader.java (extending java.rmi.Remote)
with the method,
public String lookup( String symbol) throws RMIException;
[2] Implement the StorckTrader interface (on a PortableRemoteObject derived
class, to make it IIOP compliant), and then the server to register the stock
trader with COS Naming service as follows:
String homeName =....
StockTraderImpl trader =new StockTraderImpl();
System.out.println("binding obj <" homeName ">...");
java.util.Hashtable ht =new java.util.Hashtable();
ht.put("java.naming.factory.initial", args[2]);
ht.put("java.naming.provider.url", args[3]);
Context ctx =new InitialContext(ht);
ctx.rebind(homeName, trader);
[3] Generate the RMI-IIOP skeletons for the Implementation class,
rmic -iiop stock.StockTraderImpl
[4] generate the IDL for the RMI interface,
rmic -idl stock.StockTraderImpl
[5] Generate IDL stubs for the CORBA client,
idlj -v -fclient -emitAll StockTraderImpl.idl
[6] Write the client to use the IDL-defined stock trader,
String serverName =args[0];
String symList =args[1];
StockClient client =new StockClient();
System.out.println("init orb...");
ORB orb =ORB.init(args, null);
System.out.println("resolve init name service...");
org.omg.CORBA.Object objRef
=orb.resolve_initial_references("NameService");
NamingContext naming =NamingContextHelper.narrow(objRef);
... define a naming component etc...
org.omg.CORBA.Object obj =naming.resolve(...);
System.out.println("narrow objRef: " obj.getClass() ": " +obj);
StockTrader trader =StockTraderHelper.narrow(obj);
[7] Compile all the classes using Java 1.2.2
[8] start tnameserv (naming service), then the server to register the RMI
server obj
[9] Run the CORBA client, passing it the COSNaming service ref name (with
which the server obj is registered)
The CORBA client successfully finds the server obj ref in the naming
service, the operation StockTraderHelper.narrow() fails in the segment
below, with a class cast exception:
org.omg.CORBA.Object obj =naming.resolve(...);
StockTrader trader =StockTraderHelper.narrow(obj);
The <obj> returned by naming service turns out to be of the type;
class com.sun.rmi.iiop.CDRInputStream$1
This is of the same type when stock trader object is registered in a CORBA
server (as opposed to an RMI server), but works correctly with no casting
excpetions..
Any ideas / hints very welcome.
thanks in advance,
-hari

On the contrary... all that is being said is that we needed to provide clearer examples/documentation in the 5.1.0 release. There will be no difference between the product as found in the service pack and the product found in the 5.1.1. That is, the only substantive will be that 5.1.1 will also
include the examples.

With reference to your and other messages, it appears that one should not

We currently publish an IDL example, even though the IDL programmingmodel in Java is completely non-functional, in anticipation of the support
needs for uses who need to use IDL to talk to the Weblogic server,
generically. This example illustrates the simplest connectivity; it does not
address how
to integrate CORBA and EJB, a broad topic, fraught with peril, imo. I'llnote in passing that, to my knowledge, none of the other vendors attempt
this topic either, a point which is telling if all the less happy to hear.
For the record then, what is missing from our distribution wrt RMI-IIOPare a RMI-IIOP example, an EJB-IIOP example, an EJB-C++. In this you are
correct; better examples are forth coming.
Still, I would not call our RMI-IIOP implementation fragile. I would saythat customers have an understandably hard time accepting that the IDL
programming model is busted; busted in the sense that there are no C++
libraries to support the EJB model, and busted in the sense that there is
simply no
support in Java for an IDL interface to an EJB. Weblogic has nothing to doit being busted, although we are trying to help our customers deal with it
in productive ways.
For the moment, what there is is a RMI (over IIOP) programming model, aninherently Java to Java programming model, and true to that, we accept and
dispatch IIOP request into RMI server objects. The way I look at it is this:
it's just a protocol, like HTTP, or JRMP; it's not IDL and it has
practically nothing to do with CORBA.

Please post request to the news group...
As I said, you must separate the idl related classes (class files and
java
files) from the rmi classes... in the rmic step, you must set a newtarget
(as you did), emit the java files into that directory (it's not clearyou
did this), then remove all the rmi class files from the class path... ifyou
need to compile more classes at that point, copy the java files to theidl
directly is you must, but you can not share the types in any way.
I fear that as soon as the call to narrow succeeds, the remainingapplication will fail to work correctly because it is too difficult otuse
an idl client in java to work.

Hi Eduardo,
Thanks for the help. That is the way I compiled my CORBA client, by

get a
CORBA.BAD_PARAM upon narrowing the client proxy to the interfacetype.
Here's what I did;
+ Define the RMI interfaces, in this case a StockTrader interface.
+ Implement RMI interface by extendingjavax.rmi.PortableRemoteObject
making
it IIOP compliant
+ Implemnnt an RMI server, and compile using JDK1.2.2
+ use the RMI implementation to generate CORBA idl, using RMI-IIOPplugin
utility rmic;
rmic -idl -noValueMethods -always -d idl stock.StockTraderImpl
+ generate Java mappings to the IDL generated above, using RMI-IIOPplugin
util,
idlj -v -fclient -emitAll -tf src stocks\StockTrader.idl
This creates source for the package stock and also
org.omg.CORBA.*
package, presumably IIOP type marshalling
+ compile all classes generated above using JDK1.2.2
+ Implement client (CORBA) using the classes generated above, NOTthe
RMI
proxies.
+ start RMI server, with stockTrader server obj
+ start tnameserv
+ start CORBA client
Then the client errors when trying to narrow the obj ref from the
naming
service, into the CORBA IDL defined interface using,
org.omg.CORBA.Object obj =naming.resolve(nn);
StockTrader trader =StockTraderHelper.narrow(obj); // THIS
ERRORS..!!!
throwing a CORBA.BAD_PARAM exception.
any ideas..?

Please see the post on june 26, re Errors compiling... somewherein

I suspect, you are referring to the rmi class file when you are
obliged
to
completely segregate these from the idl class files.

Using external libraries with Developer Studio 7.1 Composition Environment

Hi,
I downloaded DS 7.1 CE and tried to develop a simple application which uses an external library.
I created a development component for "external library" for the local development -> MyComponent, giving it the name "test2" (for the domain basis).
I imported the external library file using Import -> File System , then selecting the .jar file.
In the component properties browser I added a public part naming it "mylib2" setting the purpose to "ASSEMBLY" (my intention was that the libarry will be transferred during the deployment to the application server).
I right clicked on the public part to "managed entities". I selected the archive tree and checked the library file shown there (the one I imported before). #
Then I opended component properties of my web dynpro project and clicked on "Dependencies". The I chose "Add..." and selected the "test2" development component I created before (see above).
Then I tried to deploy the project (which uses this external library) using "Deploy Archive and Run"
After deployment the browser window opens and shows the ClassNotFoundException
So what did I oversee or do wrong?
BTW: Is it necessary for using external libraries to use a full fletched NWDI? Or can I use external libs also with netweaver development environments freely available for download on sdn.sap.com?
Any hints?
Thanks a lot
Hannes

Hannes,
If you want to use external libraries with DCs then you should follow the NWDI completely.
Check this step, otheways of using external libraries is mentioned <a href="http://help.sap.com/saphelp_nw70/helpdata/en/e3/de813e77d46245e10000000a114084/frameset.htm">here.</a>

Using garageband 09 with imovie 09

new to imove & garageband
some questions on using garageband 09 with imovie 09...
- Is there a URL that explains in detail how to use garageband with imove 09 to improve a voice only naration track?
- Is there a URL that explains in detail each of garage bands effects/audio unit effects on the sound track?
- is it correct that once you share an imovie to garage band and edit the sound track with garageband you can not "re-share" it back to imovie for video editing?
- in post production, I am use to doing the following for sound track:
noise reduction, compression/expansion/limiting, equalization, normalize to -1dB.
Some have garage band effects have corresponding names, like compression. But, is there a noise reduction?
Thanks
Bob

This might be helpful: http://comtechlab.iupui.edu/tutorialsfolder/tutorials.html
No URL that explains the effects in depth to my knowledge, maybe one of the books, like Missing Manual or the Apple Certified when it comes out.
Some high level info here: http://www.thegaragedoor.com/index.html
Correct, there is no round trip editing. However, you should be able to import the completed movie back into iMovie as a new event and then bring it into a project.
Not sure there is noise reduction.

Airport Extreme with External HD with iMovie Events. Can't see them!

Here I go again. I just bought an Airport Extreme. I moved my External HD with iMovie Events from my MBP via FW to my Airport Extreme. I can see the partitions in Finder and the Events folder but when I open iMovie, I can't see my events in the library. Since I didn't change the names of the partitions I was hoping for seamless access. That is not the case. I can see the Disks but they have YELLOW exclamation marks on them. They don't seem to be valid. What gives. Looks like I have some more work to do.
Any ideas. Thought this would be easier.

- it doesnt want to drag? Has anyone used this software with imovie?

I am trying to transfer vhs movies to my harddrive using videglide I have successfully recorded it and saved it onto my desktop but I cant seem to transfer the movie to iphoto for editing - it doesnt want to drag? Has anyone used this software with imovie?

I presume you mean Videoglide - which I had never heard of.
Having read the specs:
http://www.echofx.com/videoglide.html
I am wondering how it manages to digitise analogue video from a VCR. For that I use an analogue to digital converter that imports straight into iMovie via firewire.
You should contact the developers of Videoglide for instructions on how to use it.

Need to use pro mic with iPhone

I'm producing a podcast with reporters throughout US and abroad. The iPhone would make perfect recorders but we need to use mics that are more professional. Is there an interface or device available to allow us to use better mics with the iPhone?

Not really. It is theoretically possible but you would need an adaptor that could convert the standard XLR or TRS output of a higher quality mic to the specific TRRS input that the iPhone uses. From there, you would also need something with a better mic preamp that could go between the mic and this input adaptor.
While I am aware of preamps that would work, I don't know of any adaptor that exists to get the job done. If you are looking for higher quality audio than the iPhone can produce, I would recommend using a stand alone handheld recorder for the mean time. I use and Olympus LS10 and its a great unit.
