Process audio capture

I'm using my PD150 to record VO, it's got good gain, and the tapes are instant backup.
What's the best way to get the audio off for editing and effects?
Will soundtrack pro capture DV audio without any loss, or do I have to capture as a video file and then split the audio off?
Is there a shareware or other app that does this?
How should I save the audio files? 44.1/16/stereo aiff?

Quickest way would be to capture from your cam as you usually would, then unlink the video & audio tracks and save the audio as an AIFF file (FC prefers AIFF, 16-bit, 48KHz, stereo). Then you could scrap your captured clip. I don't believe Soundtrack alone can capture from your camcorder via Firewire.
Alternatively you could use the PD150's analog stereo out connected to the audio-in on your Mac and use a sound editing program to capture the audio alone. Again, format should preferably be AIFF, 16-bit, 48KHz, stereo. You should be able to use Soundtrack or Garageband to do this. Sound Studio 2.2.4 or Audacity are good shareware sound editors.

Process audio from mic and play it back. (What is wrong with my code?)

Hi, I am trying to take the audio from the mic (at javasound://0), process it (add the JMF API sample plug in GainEffect.java) and then play the processed data source. The code I have so far is below.
I am getting no errors - compiles fine - but nothing seems to be happening.
The grand goal is to take the audio being captured from the mic and process it in real time using a plug in (not necessarily GainEffect) and also play it back (the processed audio) at the same time.
Where am I going wrong? Thanks!

Ok, I narrowed my code down to this. There doesn't appear to be any infinite loops in the code now, but perhaps I'm wrong? The processor is realizing, and I am creating a player with the data source output from the processor, yet there still is nothing playing... which leads me to think that there is something wrong with my plug in implementation or my processor creation. Do you have any ideas or points in the right direction?

Audio capture filter reference count causing leak

I have a purplexing problem.
I have written my own audio and video capture filters and they work fine. I have tested with FMLE, graphedit and various other tools which i wrote myself. When i click "Stop" on the stream or close FMLE, the reference count on the audio capture filter is not release to 0, thus causing a memory leak. The leak is not a big problem, but my filters have to do some important processing in their destructors, which dont get called because its not being released.
To purplex the problem further, my video capture filter is not having this problem, only my audio.
I have written several more capture filters that literally do nothing other than register themselves to explore this problem and only the audio filters seem to be leaking. Anyone else seen such a bizare problem ?
I am using FMLE 3.1.0.8703

Thank you for your quick reply!
However I cant manage to find the panic logs in the library/logs/ or any of its directorys. Ive looked for this logs before and my guess is that they dont get created if the panic occurs during boot.

Audio Capture from DV Tape

I've reviewed many posts here about audio capture but, I am unable to figure out what the "trick" is to capturing audio alone with the video using the new iMovie. I'm connected via Firewire and I'm able to view the video in capture mode but, I hear no sound. I've checked iMovie Preferences and System Preferences and everything seems to be OK there.
Is this the way this new version of this program functions? I wish I didn't have to post a msg here because, I'm trying to read the previous post and trying anything that seems to pertain to my issue without the desired results.
Can someone please shed some light on what's going on with this function of this program?

I assume you are wanting to hear the audio as you are importing and not that you have no audio once it is imported.
imovie 08 doesn't play audio while importing. While you are using tape (that imports in real time) imovie now imports from a variety of different types of camera such as AVCHD (which isn't imported at real time. Therefore it is no longer logical to playback audio on import.

System Settings-Audio Capture

In FCE, trying to capture VHS via DV converter box. The sound is not coming over. In system settings/scratch disk (internal hard drive) the audio capture is grayed out. Analog RCA composite video & stereo audio connectors in place. How do I get my sound?

You can't get audio during capture as firewire has control.
Use the audio from the play device if you need to hear what's happening. You will notice latency on the FCE capture window, that's normal as well.

Media Encoder not finding "audio capture device"

Hi,
Im using Adobe Flash Media Encoder with Dxtory for Twitch streaming, and at first it worked fine. Recorded both my mic and game audio perfectly. Then seemingly suddenly, I fired it up and it wouldn't stream the game audio. It would my Mic, but thats it. I then unplugged the mic and it started saying I had no Audio Capture Device. I checked in Dxtory and its set up the same as it was when it was working. It picks up both the mic and speakers like it should. I have uninstalled this program multiple times, both 3.1 and 3.2 versions, and each time when I re-download it, it loads up the same profile I had before. So when I am uninstalling it, its not uninstalling everything for some reason. Even though the program is no where to be found after its uninstalled. I have downloaded xsplit, and it picks up the game audio and my mic. So its just this program. Anyone have any ideas? I cant seem to find anything online about this issue.
Thanks!

From where? PP sequence? PP bin? PP Source Monitor? Watch folder?

Audio Capture problem

When Capturing from a DV device on to final cut express HD, only audio is "caught". When I checked the scratch bin the audio selection was disabled (like, the check-bow was dimmed and unable to be changed). I'd like to be able to capture audio without using the voiceover feature and having to completely match audio with video. Ya dig?
Thank you (for at least reading this)!

then why is FCE capturing video but not audio. all the settings are correct, the only thing i fan find wrong is the "audio capture" check box in sratch disk settings under system settings is nulled to where you can't do anything to it. So, unless it's normally like that, I'd say it has something to do with the way it captures audio.
so, please tell me that has nothing to do with it so I can find another reason why it won't capture audio.

Audio capture

I want to whether the cross-platform supports the audio capture?
If not ,are there any methods to finish audio capture on handheld

Hey DaddyPaycheck, the tape deck is actually one of those boombox/shelf stereo with cd carousel, and dual tape deck (5.1 speaker system). Audio was working just before I disconnected the speakers. I tried using the speaker output jacks, as well as another audio out, but neither one of them was putting out audio through my computer's speakers. The sound preference recognizes the iMic, but not the Pyro. But the apps I mentioned recognizes both. Selecting the iMic for output in the system preference doesn't work either. I see the bars moving, but I believe that's just random noise the iMic is picking up.
So, by all intent and purpose, the set up I have should technically work?

Audio Capture only happens if its more than 5 seconds

Hello,
I'm writing a midlet that does audio capture on the LG CU500 phone. When I capture for 5 seconds or more, audio capture works as intended, however if I only record for under 5 seconds, it doesn't work. There is no timer. Would could be causing the problem?
Thanks
aztec30

Here is a snippet of the code that i'm using. When playing back, if I record say 10 seconds, I only hear about 7 seconds of the recording. About 3 seconds are cut off at the end. If I record for say less than 4 seconds, nothing seems to be recorded, nothing plays back.
To record I do the following
try {
if(player != null)
player.stop();
if(ctrl != null)
ctrl.commit();
player.deallocate();
player.close();
ThreadSleep(500);
if (player==null) {
player = Manager.createPlayer("capture://audio?encoding=audio/amr");
player.realize();
player.prefetch();
player.addPlayerListener(playerListener);
is = new ByteArrayOutputStream();
ctrl = (RecordControl)player.getControl("RecordControl");
ctrl.setRecordStream(is);
ctrl.startRecord();
player.start();
} catch (Throwable e) {
Once recording is stopped I do this
try {
player.stop();
ctrl.commit();
player.deallocate();
player.close();
Thread.sleep(500);
if (is !=null) {
playback= Manager.createPlayer(new ByteArrayInputStream(is.toByteArray()),
"audio/amr");
playback.addPlayerListener(playerListener);
playback.start();
} catch (Throwable e) {

Audio capture lost after installing snow leopard

Has anyone else had problems loosing their audio capture in Premiere cs4 after installing Snow Leopard?

Just wondering, is that a plug-in for Premiere?
Similar problem with After Effects maybe?...

Audio capture support won"t install in CD spin doctoris there something I need to know?

How do I install audio capture support? I/m getting an error message: The Installation Failed. Does anyone know of a solutioon?

AFAIK, CD Spin Doctor requires Toast Titanium 9. The latest CE Spin Doctor that works with it is 5.0.4. Once you launch it, the first window that pops up is this.

Audio capture recording .mov - .m4a

I accidentally saved an audio capture recording with QT without switching it to save as audio. It's now a .mov (saved as movie) instead of .m4a. How do I convert from the .mov to .m4a? Also, is there any way to make it save as audio (.m4a) by default?

Ah, yes, that works! Thank you.
A follow-up question: When audio capture is stopped, how can the client program find out when all the audio data has been written to a file on the server. The client needs to know this to perform subsequent operations on the audio file.

Audio capture scratch for iTunes import/48kHz convert

Working in first FCE HD project. I want to import an additional music track from iTunes. Following the manual's instructions for converting iTunes files to 48 kHz for import, it says to "navigate to the project's audio media folder". In the external hard drive's doc folder it shows all the necessary folders there except Audio Capture Scratch ( which was default checked and unselectable in Settings prior to the initial video/audio capture of existing commercials, etc. from a deck).
Apparently setting up this Audio Capture Scratch as a destination that shows in the FCE docs window must be done after the initial set-up. (?) If so, I can't find how to do it. According to what I've been reading, though, the Audio Capture Scratch should already be among the 7 folders (Capture scratch, Render files, Audio render files, etc.) but it's the only one missing. Is this even related? Can audio be imported directly to the project as opposed to the ext. drive?
Question is... Should that in fact be the destination folder? Or do I need to create an "audio media folder" for this project? If so, how? I've not found anything in FCE Help or the Brenneis manual.
Thanks for any help on what must be a basic conceptual hole in my limited mental model.

You can import audio files into FCE from any location
on any HD. The audio file itself could be in your
iTunes music folder but if so, I suggest making a
duplicate copy of the song file in some other folder
(your choice, your location, your folder name) to
minimize the risk of accidently messing up something
in your iTunes music folder.
You could even drag a copy of the file from the
Finder into the FCE Browser. Once it's in the FCE
Browser, you can drag the music file onto one of your
audio tracks.
The ideal format is AIFF, 16-bit, stereo, 48Khz.
Truly thanks for that. But... In order to convert the iTunes file to the above, I have to go to the iTunes Pref. window and the folder location field, click the Change button and navigate to the "project's audio media folder"... But I don't have, can't find or don't know how to make that folder. So I can't specify the destination. I'd love to drag/drop, but the format won't be AIFF, 16 bit 48kHz.
When I read the manuals instruction for importing directly from a CD, it also says to drag the files into my "project's audio media folder", so I'm back to the same problem. I guess I could try dragging from the CD directly to my browser, and I will, but even if that works for now, I need to understand what/where/how to create the audio media folder, as I fear I'm missing a basic understanding here.
And why is there no Audio Capture Scratch folder showing in the FCE doc folder? Even if this unrelated and irrelevant, I'm still puzzled about that. I'd appreciate any clues here. Thanks again.

"Audio Capture Device not selected" message? Help please!

Howdy folks,
I just got a new PC, Windows 7 OS, I've installed ManyCam and version 3.2 of FME and am looking to broadcast again. I don't recall this issue with my old PC (XP OS, Broadcaster StudioPro virtual cam and FME 2.5). I updated to 3.2 as suggested/recommended in previous posts, but I am getting a message telling me to "please select audio capture devise connected to your system." What am I doing wrong or might there be something that I need to download that I missed?
Any help you can give is greatly appreciated. I truly loved using FME 2.5 but am doing like you suggest here.
Peace,

Hello -
My problem was fixed by setting a recording devise in my "sound" menu.
What I did was -
1. Open the sound menu from the control panel.
2. clicked on the recording tab.
3. Chose "Stereo Mix - Realtek High Definition Audio" as my default device.
That solved it. It was almost too simple. Hope this helps you!

Audio Capture not available / grayed out

I have a Samsung SC-D263 connected and when I try to capture video in FCE there is no audio. When looking in the settings, the check box for audio capture is grayed out... any ideas?
I managed to find drivers for the camera, but i don't know how to install them...

What audio checkbox are you talking about?
Do you see the video in the capture window? Do the meters move?
