Problems capturing audio track

I am having a problem capturing from my DV camera into Final Cut Pro (version 5.1.4) on a souped up G4. I made a few changes to the hardware configuration recently, but the problem started prior to these upgrades so I don't think it is related. I installed an ATA drive and replaced a defective USB2/FW800 Sonnet card.
I thought I had a problem with the playback head on the camera when the capture issues first started. I got black horizontal bars on the screen of the camera as well as on the screen when I attempted to capture footage. I also got timecode error messages. I was able to capture some of the tape in FCP using a different camera, but upon examination I noticed both audio tracks are missing small segments of data. There are a few blank spots scattered throughout the footage. The picture is fine. The problem is in the audio tracks only. both tracks in the same area.
One of the camera repair people I talked to said the tape could be bad. Does this make sense if only the audio track is missing segments and the picture track is complete?
Thanks, I appreciate any help you can give me in figuring this out.

Thanks for your suggestions and opinion. I am reading everyone's comments. In order to get the most from this discussion, please answer each of these questions separately so the people who are following it will have no trouble following the answers that apply to each.
I distinctly remember when I was shooting the footage of the problem tape, the picture looked fine. It was not until I tried to review the tape that the problem appeared.
1. Is it possible that the camera works for shooting but the camera playback head is causing problems?
2. Can a bad playback head damage the tape on playback?
2. Can shooting onto a bad tape damage a camera?
3. Is it possible to shoot with a camera with a bad playback and then use another drive for playback?
Thanks for your help. I do know a few people who are having playback problems, since all the tape cameras are getting old, so we appreciate this discussion.

Problem dragging audio track

I am using iMovie HD 5.0.2 to sync some audio with a video. I only need to line up the audio and then export to AIFF so I can covert the AIFF to AC3 and mux it with an m2v file. My problem is that I was able to clip the unneeded beginning of the audio and drag the audio clip forward to match up with the video but iMovie is not letting me move the audio forward again. I am a touch off (the audio starts at .08 seconds into the video and I need it to start at .07 seconds). iMovie is not letting me move the audio to the left up to that .07 second mark (or even before that mark had I wanted it there) nor is it letting me move the audio back. Additionally, it seems to take a lot of work just to highlight the track again so I can try to move it.
Here is an screenshot in case that is helpful: http://img691.imageshack.us/img691/7397/picture2kb.png
Can anyone recommend how to solve this problem?

Hi Danielmak,
I haven't used iMovie HD (nor HD 6) for a while, so working from memory here!
Drag the audio track to the Desktop. This creates an .aiff audio file which can be opened in QuickTime Player or iTunes or other audio program. Import the aiff track into iTunes. Now place the iMovie playhead at the exact point where you wish the audio track to start. Finally, highlight the track in the Audio section of the Media window and click on "Place at Playhead".
If this works successfully, you will need to delete the original audio track, which will be still in place. Dragging it to the Desktop doesn't move it, but simply copies it.
These instructions apply to iMovie HD 6 but something similar should also work for iMovie HD (version 5.0.2) - just can't recall the exact layout.
If iMovie doesn't like the .aiff file, you may need to convert it to mp3 (easily done in iTunes).
Hope this works for you!

Problems with audio track when burnt to DVD

Hi there,
I'm using CS4, and have created a 30 minute film which I've exported as an H.264 - it's 653MB. When I play this file from my PC, it's perfect. When I burn it to a data DVD, however, the audio track is interrupted every few seconds with blips of silence - like it's stalling. (I've been unable to burn it as a video DVD so far as the various software I've tried rejects the file format.)
I've burnt it twice on my laptop and once on another desktop with the same results. I urgently need to send the file to a Mac owner - what should I do? Could this be a fault with the file or with the burning software? Perhaps I didn't do something right with the audio track?
I'll greatly appreciate your help!
Thank you :-)

For authoring a DVD-Video, follow Harm's advice and Export to DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio.
For a DVD-Data, you should not have an issue with the H.264, BUT some have had problems if using Apple's H.264. Many users find that the Lead, or MainConcept H.264 has fewer issues.
Also, do you have a Matrox card? They have been known to cause Audio issues, so you will definitely want to update any Matrox drivers.
Good luck,

Problems capturing audio under linux

Hello. I have developed an application that captures audio using the Audio API of JFM. The problem is when I start capturing audio under Linux (all the audio devices are well configurated), the JVM returns the following error:
java.lang.IllegalArgumentException : Illegal request to write non integral numbre of
frames (13107 bytes)
The piece of code that causes the error is :
while(!stop) {
numBytesRead = inputLine.read(data,0, data.length); bufferoutput.write(data,0,
numBytesRead); }
where inputLine is a TargetDataLine.
Under Windows this runs OK. Anyone know why not under Linux?
Thanks

Hi!

Have you got any idea about the problem ?
Thankyou.

Problem capturing audio

Hello!!
I am trying to capture audio using jmf 2.1.1.e in Linux (SuSE 8.1) with jdk 1.4.2_04. I have "alsa" properly installed. However, when I try to capture using jmstudio, I am shown "javaSound audio", LINEAR, 44100 Hz, 16 bits, stereo, little endian and after cliking OK I get :"Could't initialize the Capture Device".
I also try to run a code to capture audio, using the following:
Vector audioDevices = CaptureDeviceManager.getDeviceList(new AudioFormat(AudioFormat.LINEAR, 44100, 16, 2));
CaptureDeviceInfo audioCDI = (CaptureDeviceInfo)audioDevices.elementAt(0); //I get javaSound
ds = Manager.createDataSource(audioCDI.getLocator());
processor = javax.media.Manager.createProcessor(ds);
But I get the following exception:

Could you be so kind as to help me, please???
Thank you very much in advance.

Hi wew64.
I m new to JMF. I just made a simple media player not any more. can you please tell me what is "alsa" and "arts".
actually I want to control my Sound card properties like "Microphone, Line In, etc...." is it possible in java if it is please tell me.
I will be very thankful to you
I m very upset about it because it is minimum 3-weeks late, my project is pending on this stage. All i want to do, just to mute the volume of "line in" (property in my sound card, which takes audio data from a TvTunner card and leaves this audio data out to the speakers.)so that only the audio from my computer's( any application like media player) can goes to the speakers, not the audio comming from the TvTunner(My TvTunner is opperated by the application provided by the vendor, I did not develop this on my own in java. I just made my media player in java). Yes this is the PROBLEM that both audios from TvTunner card and from My Application are being transmitted to speakers simultanously. But i want, when my application is running, the audio comming from TvTunner should be muted and when my application is exited, the TvTunner's audio should be unmuted. And this is only done by Line In property because Audio from TvTunner card is got by the Sound card through the Line In property.
I tried my best to find out the solution but could not get any thing right.
Please Help me
thanks

Problems with audio tracks

Happily pressing on with my first project when problems arose with audio tracks. Suddenly - when I added video clips I got sound on A2 but nothing showing on A1 (and sound only from right hand speaker). Clips are okay as sound is on both sides when played in Viewer and Canvas just can't add them both to timeline. It was okay up until the point I did my first audio fades within a clip (using the 'elastic bands'). Now I can't even insert a clip with both tracks ahead of that point. A1 just won't accept anything.
Now when I add a clip I only get audio on A3!!!!
Voiceovers all went onto A6 and are okay but is it normal for them to hide down there?
I am sure this is finger trouble on my part as I am so new to FCE but can anyone tell me how to recover?
Thanks,
Tom.

Sounds to me like the audio targeting is amiss somewhere.
In the audio tracks you will notice a1 & A1: meaning audio track 1 and the audio will go to that track when edited. To get stereo, two tracks will be used eg. a2 & A2. Having A1 and A2 is FCEs default setting with a1 & a2 selected. This setting will place stereo audio into these default tracks. If, for example, you want the tracks to be edited to A5 & A6 then you move the a1 to a5 and a2 to A6 (click and drag). This is called track targeting for obvious reasons, untill you change it, all new edited tracks go to tracks 5 & 6.
Click on a1 twice, did you notice it move and seperate from A1, this is a de-selected state (a gap between a1 & A1). When a clip is edited to A1 in this state it means no audio will be added to that track. Most likely you have an unlinked audio track. I hope this brief bit of info helps you figure out what audio ends up where in the Timeline.
Regarding recovery, you could try the AutoSave Vault. Go back to a date and time that is before things went wrong and open that project.

Problem capturing audio in WTK

When I capture a sound with WTK emulator, picks the first second and starts to repeat again and again, to become noise.
This only happens in the emulator, not on the phone.

Already found the problem, this is caused by my soundcard.

Problem inserting audio track into timeline

Sorry, I'm a newbie, and I'm sure this is a dumb question -- but I can't seem to answer it myself.
Working with the latest Windows CS6 update and 1080/60p video from my Panasonic AVCHD camcorder, I find the only way I can move a clip from the Source Monitor to the Timeline is by dragging and dropping. Any other method (clicking on the "insert" icon, keyboard shortcuts) moves only the video, leaving the audio behind.
What am I doing wrong, or what do I not understand?

Okay, that sent me in the right direction. Now I understand.
Thank you!

Problems with audio track through US-122 in Logic Express

Hi,
This may be a completely stupid question, but I'm having problems with recording through my Tascam US-122 in Logic Express. I can't get anything to register on the level meter in Logic Express (neither direct input nor microphone input). However, I can get the input from the Tascam to register in the system preferences menu outside of Logic, and can get the built in mic on my IBook to register inside of logic. Does anyone have any ideas for me to try out? I've looked in the manual and I'm supposed to be getting the Logic Express training book soon, but I was hoping to record sooner than that.
Thanks!
Shawn J

Sorry, ignore the above. I needed to enable record before the level would show up.

Problems with audio panning.

Am having problems with audio tracks. For example: when capturing a clip where a person is talking, there would be 2 tracks of audio - one a radio mic (Track 1) and another mic (Tack 2)capturing ambient sound. I often delete the ambient track (Track 2) and am left with the the main audio from a radio mic (Track 1).
The problem is when I open up the main audio track (Track 1) and pan the audio track from -1 to 0 or even to +1! It says it has done it but the sound still comes out of the left speaker.
It is a very recent problem that I wonder may be something to do with preferences or settings.
We have had no problems with the speakers at all.
Thanks very much,
Geoff

You have your audio outputs set to 'dual mono', not 'stereo'.... go to:
Sequence>Settings> 'Audio Outputs' tab > then highlight the 'Stereo' button, then click OK...
problem solved...

How can I capture Audio Only?

Hello,
I have FCEHD 3.0 and would like to capture audio tracks only with Capture Now (from a non-controllable device via Canopus). There is no "Audio Only" option in the capture window. Any ideas??
Thanks,
C.J

Hi(Bonjour)!
No way to capture audio only with capture command.
Simply delete the video track in the timeline.
Or:
Plug your camcorder audio output in your in-line socket on your mac with an audio 1/8" wire, do a voice over record.
The resulting audio file will be a "analog" one.
You can also use a sound editing programm like Sound studio or audacity to capture your audio-in content, and import the resulting file in FCE.

Problem capturing Stereo audio

I know I have 2 separate tracks of audio on my tapes. One wireless mic and one shotgun mic. I have tried all audio capture settings, but FCP just keeps on capturing the first audio channel? Any suggestions how to get both audio tracks captured.
I even tried to capture with tapes that I´ve succesfully managed to capture both audio channels before. I just added a second scratch disk, also internal, could this have to do with my problem?

When I open the Log & capture window there are items missing in the Capture Settings and Clip Settings Tab?! I can´t for intsance choose how many audio cahnnels I want to capture. Anybody seen thing like this?

Audio tracks suddenly missing from capture... need help!

Hi! I have been capturing video (with audio) successfully and routinely for months now. Suddenly, though, when I capture video... from the same device, with the same preset... the clips have only 1 Video track, and no Audio tracks. My camera is still recording audio (and I still hear it during the capture), but the audio tracks just aren't there in the resultant clip. It seems to me like FCE has just decided not to capture audio, as if to say "pffft... we don't need that." But why this happened is beyond me!
Even within this same project, I have other clips captured with audio just fine. I didn't even realize it was an option NOT to capture audio. There aren't any settings to that effect in the Capture window... i.e. there's nothing to turn OFF, so I don't know how to turn it back ON! HELP! How do I get audio back on my captured clips? Is there a way to toggle this? How can I possibly be getting video without audio when the preset has already been working for this device?
Things seemed to change once I started using the Voice Over tool. After that, none of my captured clips have audio. Something I did on or around that time changed FCE internally. I combed through the manual but didn't see any leads. They assume if you have the right preset, it'll just work. No mention of disabling audio.
Please help, because I'm just about ready to throw my Mac throw the wall. I even tried reinstalling FCE, just to get it back to the previous state, but it didn't help.
P.S. I also haven't changed anything on my camera that would affect audio. I feel this is just a setting somewhere in FCE that I can't find and don't even know where to look for it...
Thanks in advance!!

Hi. Where should I look for them? I haven't had much success finding things on my own, so please spell it out for me.
I just find this so odd... it would be one thing for the tracks to be silent or garbled, then I would think this was a cable issue or the camera. But I can't even imagine why the audio tracks would just not be there. If I saw a preference for "Video Only Capture" somewhere, it would make sense.
Anyway, thanks. Please tell me where there's a prefs file, and I'll roast it.

New audio track in arrange page problem

In the LSA I have 64 audio tracks and 32 audio instruments set up. When I open Logic, my autoload contains 16 audio tracks and my environment is configured as I set it up in the LSA. Everything is as it should be. However, when I select track 16 in the arrange page and use the key command control>shift>return to add another track, audio16 is duplicated. When I use the menu to 'create with next instrument' audio17 is created, but in my environment, my 64 audio tracks are reduced to 24. Using the menu to add audio tracks only lets me add to 24.
I've trashed my preferences but that did nothing.
One thing that may be relevant is that after setting up the LSA as described above, I copied an old autoload from my powerbook that only contained 24 audio tracks. After realizing that I need more tracks I trashed that autoload and re-ran the LSA. (on a side note - your autoload will trump your LSA set-up if they differ). I think that the old autoload is still causing a problem even though I trashed it.
Any help in the frustrating situation is most appreciated!

It is normal that Logic uses the same audio object
when you create a track with control-shift-return,
that's the way it's supposed to be. If you want to
create a new track and a new audio object assigned to
it, "create with next instrument" is the way to do
it. You could also use "create multiple..."
in the drop down menu it says that the key command for 'create with next instrument' is control>shift>return.
If you're limited to 24 tracks, I'd check in your
audio preferences. Your maximum tracks limit is
probably set to 24 tracks.
my audio preferences are set to 64 tracks of audio.
thanks for the reply!
