IoLA audio

I have an AJA IoLA and need to clear understandng about setting audio levels in FCP when using the AJA device.
Their manual says to not exceed a -20 peak db digital signal.
Using the VU meters in FCP, not exceeding this parameter cause low audio levels requiring the use of Sound Track Pro to boost the gain then importing the audio back into FCP.
Capturing video and audio direct via firewire through a camera rather than the AJA device allows me to capture audio with peaks near zero on the VU meters in DFCP without distortion.
Using the AJA device, exceeding the -20 peak on the VU meters in FCP seems to create distortion.
I need a better understanding audio levels to use in FCP using the VU meters in FCP.
Can anyone help?

Tried this today.
Contacted AJA tech support yesterday and he had me revert from driver v2.1 back to 2.0. Wouldn't print at all, then, so we moved back to 2.1.
We can print now, but still having the pop issue.

FCP/AJA IoLA audio glitches when printing 4 channel audio to Digibeta

Hi...trying to troubleshoot my wife's machine at here office.
G5 DP2.7GHz
8GB RAM
FCP Studio
AJA IoLA
Sony DVW A500 Digital Betacam Deck
DVCPro 50 footage (SDX900)
DVCPro 50 sequence for editing the show
10bit NTSC sequence for graphics & printing to tape
Have updated all drivers & firmware. This is the 2nd different DigiBeta deck we've tried, as well.
Sending TV show episodes to tape, network requires 4-channel: 2 stereo, 2 discreet.
When the sound on the music channel drops completely away, we can see and hear pops hitting on the audio meter. It seems to be little glitches from other channels popping in and out of channel 4. Sometimes it's a voice. Sometimes it's nat sound.
Probably happening all the time, but it's only visible/audible when it's isolated. It doesn't seem to do it on any other channel.
These audio files are mastered in ProTools and brought into the timeline as one long file for each segment, so there are no parts of the sequence that have nothing there.
The pops do not show up on the Final Cut mixer.
The pops only show up when either viewing on external monitor or printing to tape.
Audio is 48K.
All we can do to get rid of them is keyframe the mixer to pull all sound out of that track once the music fades down. Sure, no big process, but our sound mixer is already doing that in ProTools. It's doing the same thing twice. There's nothing there, so why should we have to bring it down on every show?

Audio monitoring through AJA IoLA

I have just started using FCP and am having trouble monitoring audio during playback of clips in an existing timeline. I am using an AJA IoLA as my D/A interface and everything works perfectly except for audio playback. I have my video monitor and my speakers coming directly out of the AJA. Video works fine all of the time. Audio works while capturing but not once it is captured.
I have read the instructions many times but it does not seem to address this issue. Oddly if I choose "external video-still frames" I can hear the audio but only get a still frame of video. This is not helpful. If I choose "external video-all frames" I get moving video but no audio. Again, not helpful.
Does anyone have any suggestions?

So, what exactly are your sequence settings, your export settings and what are you sending the Audio and video to?
for example, are your speakers turned on? If going to a mixer, do you have the correct input selected ....
Basically, if the audio is following the video and the video is making it out, you either have
a. no audio in your clip
or
b. the targeted audio device is not set up to receive the signal.
or
c. the i/o is screwed up. (does it have the latest drivers?)
Good luck.

Converting 8mm tape to DVD via FCP (AJA IoLA TBC??)

I am playing old home video 8mm tapes out of a Handycam S-Video out (audio from the a/v jack), into an AJA IoLA. I am having a problem with dropped frames, they are happening all over the place. And although I have it set to not abort on dropped frames, when I view the captured video, there are hideous audio spikes and the audio and video are completely out of sync by several seconds after these spikes occur. I've tried different tapes and had the same problem.
I have combed the discussions a bit and found that I need a Time Based Corrector. Does my AJA IoLA take care of TBC in some setting somewhere? Or do I need to purchase something else?

FCP 4.5
Mac OS 10.4.10
Quicktime 7.2.0
I'm not completely sure that the AJA allows me to capture to some form of DV. It only gives me a list of specified presets, and it looks like all of them are uncompressed.
This is copied and pasted from my Audio/Video Settings Capture Presets Summary when "AJA Io LA: S-Video 10-bit NTSC US 48KHz" is selected:
+Use this preset when capturing NTSC US material for Uncompressed 10-bit using+
+S-Video input via AJA Io LA+
*Using ProIO Uncompressed 10 bit 422 Video for video input*
*ProIO 10-bit S-Video 29.97Hz US using NTSC*
*29.97 frames per second*
*Uncompressed 10-bit 4:2:2 at Best quality.*
*24 bits per pixel*
*720 by 486*

Audio Sync from SVHS capture

okay, my head is about to explode. We have captured about 8 hours of SVHS footage using an AJA IOLa, using the DV/NTSC preset, 29.97fps, audio at 48K, no one can remember if we set it for non-drop or drop frame. The problem we have is that the audio drifts out of sync very badly. Any ideas?
BTW, running 10.4.8, 5.1.2, everything is up to date on this machine(G5 DP, 1.5 gigs, G-Raids, etc.).
K

Any idea why this is happening?< </div>
You can search here for hundreds of threads on drifting audio. The causes are way too numerous to attempt to diagnose from where I sit but here are some.
The problem is usually caused by your transcoding or input system. If you are patching your VHS into a DV camcorder and coming in on FW, things should stay locked. If your deck is from Canon, you have a BIG probme right there and you must use my method to make the clips the same length. Canon's DV codec is non-standard. You can easily correct the issue with my previous post by rendering the audio.
If you are coming in through a capture card, you need to talk to the mfr of the card.
The other question is why are you trying to bring that much material into FCP? Try dubbing it to a DV tape and capture only what you need.

Unable to capture audio

Hi,
Last week I updated the drivers for my Blackmagic Multibridge extreme. Now when I try to capture the material in FinalCutPro 5.1.4 I can see the picture, hear the sound on my monitors (they are connected directly to Multibridge), but the captured material doesn't have sound, because it takes the sound from the internal audio input. I tried to capture from Blackmagic Deck Control (an external application) and it works fine, it captures with sound. So I suspect I have to change the audio input in FCP, but dont know where. In audio/video settings in FCP everything is set to DeckLink (Multibrige extreme).
Where is the problem?
Thanks,
Simon

Thanks for the reply.
Looking at system preferences I found that audio input was set microphone. Don't know how it happened. I switched it to DeckLink and now FCP displays 16 input channels in Log and Capture dialog. I didn't try to capture yet but I think it solved the problem, because before I had only two channels displyed.

Unable to capture audio from BlackMagic HD Extreme via Voice Over tool

Hi !
I'm trying to capture audio via my BlackMagic HD Extrem card using the Voice Over tool in FCP6, but I can't, no audio is incoming.
I can ingest audio with video using log and capture, then I know my card and my cables are working.
I tried to set the BM card as audio input in my Audio's System Prefereces Pane, but it isn't working either.
I've been looking on the BM website, but I found nothing.
Can you help me ?
Thx

Thanks for the reply.

Unable to capture 2 audio tracks

FCP refuses to capture 2 audio channels?! I have one mic on channel 1 and another mic on channel 2 but FCP captures only 1 mono track eventhough in Clip Setting both channel 1 and 2 are selected. Does anybody know what could be wrong?
Another thing is that when I have captured a clip - it won´t appear automatically in the Browser as it always has done? Now I need to import the Clip from my Project folder. FCP going crazy.

Audio malfunctioning on hp ultrabook?

Hello! So i just recently got a laptop in late june almost early july.
Its a HP ENVY touchsmart 4 Ultrabook
Its not even 2 months old and the speakers on here suck. They kida slurr and like lag. Its stutters really bad. I can't listen to 1 song without it doing that. And sometimes it freezes but only very quickly. And also my down arrow button came off like within 2 weeks.
This is my first Laptop so im not sure if i can return this and get a new one because its audio is malfunctioning and stuff? I have a one year warranty on this.

Hello Gurjot24,
If you want to return it rather than getting it fixed, please contact HP support over the phone to see what options are available.
If you are in the US or Canada the number is 1-800-474-6836, if you reside in a different location click on this link. Click on your country, then click “technical support after you buy”, and the number will be provided.
I hope everything works out.

How do I use my web cam to record audio and video? I can get the video to work but no sound.

I want to record both audio and video at the same time. The video works fine but not the audio. I do use Skype without any problems using both.

PwmBoat,
This made me smile, because things like this do make me smile... I never make videos on YouCam, but I did this time, so I could test this one out.
You did not say what webcam software you are using...
======================================================================
Video and audio recording works on YouCam V3.5.1.4606
Make sure you have turned on a working microphone in Settings:
YouCam > Right-Side Settings >
Right-Side, Lower-Right, Select a working Microphone from the Drop down list
AND
CHECK "Capture with audio"
OK
You can also buy (for $38 US) YouCam 5.0 from the Cyberlink.com website and it has audio/video and all sorts of other goodies, too. (They have 3.x as well, but why buy what HP already gives you?)
==========================================================================
I hope this helps!
We work hard to help!

I have an apple iphone 4 that I want to download audio books from my library onto it. I cannot figure out how to do that. The iphone does not show up on my mac laptop as a connected device. Does this kind of download have to run through itunes? Thanks

Yes it is done through iTunes. The iPhone will never show up in Finder as a device. The following is general information on iTunes sync: http://support.apple.com/kb/HT1386 and the following is a previous discussion where the post by Andreas Junge helped others that had a problem syncing audiobooks: https://discussions.apple.com/message/20052732#20052732

Why does GarageBand audio work for guest user but not my account?

Hello, I have a 15-inch MacBook Pro (2.2 GHz Intel Core i7, 4GB 1333 MHz DDR3) from late 2011 that I bought brand new in 2012. I'm running OS X Mavericks 10.9.4 and my MacBook has 500 GB of storage.
About a month or two ago I tried to download the new GarageBand (10.0.2) but I had trouble completing the loops download. The download would stop halfway through because of a network error. So last week I decided to try to download it again, and I was able to do so after reading some discussions about the issue. I successfully completed the download in safety mode and then I restarted my MacBook. At this point I was able to open GarageBand 10.0.2 and create a new project. Unfortunately, there was no audio coming through the output and sound bar for the various audio components in GarageBand. I had no audio when previewing the loops or playing it back in an audio track. I didn't really test anything else out because I figured I needed to fix this problem first. I have read many discussion boards about audio problems with GarageBand. I have already made sure everything is set properly in the GarageBand preferences and the audio preferences in system preferences. I've tried restarting GarageBand and restarting the computer.
This evening I found a discussion from the username icewhatice and they seemed to have had my exact problem. I'm not sure that I found the answer on this discussion though. For reference, this is what icewhatice posted: "I have no audio coming from Garageband 10.0.2. Downloaded it on Saturday and have spent the last two days trying to figure out why it won't work. I'm using a macbook pro with an Alesis QX49. GB registers keyboard when I plug it in but no sound whatsoever, not even from the onscreen keyboard. It seems to read the keyboard as if I play a C chord, it appears in the display. I've done all the obvious stuff like check preferences, restart, I've deleted and downloaded new GB several times and always with same result. Actually, it took me about four attempts to download it in the first place as I was getting an internet connection error message right at the end of the download, and I see others have had that problem. Managed to solve that by downloading in safe mode but now the no sound thing is driving me absolutely crazy because I can't play my keyboard!!!!! Also, worth noting that there is no audio level being read anywhere, I believe in the new version this appears in the volume control at the top. I've also looked into it potentially being a problem with my keyboard and it possibly needing an update but can't find any difinitive answer for that anywhere. I've stopped looking into that because the on screen keyboard doesn't even work - if that worked then I would know at least GB works and it's something to do with the keyboard. So, I am at a complete loss. If anyone has any ideas about why this is happening or what I could do to solve then I would be very grateful."
After reading this, I realized that I am unable to create new tracks, and I realized that I have the same problems with old projects saved from the last version of GarageBand I had. I have not tried to download GarageBand again since it did not work for icewhatice. léonie ended this post by saying: "Something is certainly wrong - either the current project, some settings in your user account, or the downloaded GarageBand version. Or incompatible software may be interfering. If a new project does not work, try to test by logging into a different user account, for example the "Guest User" account. Create a new project using this account. Does GarageBand work better from this account? Then we will need to troubleshoot your preferences."
I have tried this and started a new GarageBand project in the "Guest User" account. GarageBand was working fine in the "Guest User" account and all of the audio was working properly. Does anyone know how I should troubleshoot my preferences?

If an application is working in a different account, but not in your regular account,try t find out, what you configured differently in your own account, for example start-up items or preference panes you are using, applications and other helper tools, that are only installed for your regular account. As a first guess, remove GarageBands preference files from the user library in your Home folder.
But you will have to reset all settings you did in the GarageBand preferences dialog. And GarageBand will not remember the last project. You'll have to find the file manually.
Remove these files from your User Library to a folder on your Desktop:
~/Library/Containers/com.apple.garageband10/
~/Library/Preferences/com.apple.garageband.plist
~/Library/Caches/garageband
Quit GarageBand, then remove the files to a folder on the Desktop and restart the computer, before trying again to open GarageBand.
You user library may still be hidden, as is the default in Mavericks: To open your hidden user library:
Select the "Home" folder icon (the little house) in the Finder's sidebar and press the key combination ⌘J to open the "view options".
Enable "Show Library Folder".
Then open the Home folder and open the Library folder inside and navigate to the Preferences, Caches, or Containers folder. Remove these folders completely - don't leave anything inside: ~/Library/Containers/com.apple.garageband10/,
~/Library/Caches/garageband .

Does the mini DVI port cary audio if using a Mini-DVI to HDMI Adapter?

Hello everyone,
I've heard it is possible for a DVI port to transmit audio data to a HDMI connection if a DVI to HDMI cable is used, which will allow the sending of both audio and video to your TV. see: http://en.wikipedia.org/wiki/DigitalVisualInterface
I'm assuming this is not possible using apples mini DVI port, but just wanted to check to make sure. My main goal is to get surround sound out of my powerbook. To do this by simply adding a Mini-DVI to HDMI Adapter would be GREAT!

Hi Jonathan,
I'm assuming this is not possible using apples mini DVI port
Yup, no audio, unfortunately. The audio will have to transmitted separately via the analog audio output.

How to connect sound or audio to my tv using hdmi adapter. I tried to connect thru sound settings but my tv is not found.

how to connect sound to my tv set using hdmi adapter. Im using 2009 macbook pro 13". I went to sound settings then output and it shows internal speaker built- in, it wont locate my tv set. pls. help, thanks

You probably can't because it looks like your MacBook Pro is too old to carry audio over HDMI. You will need to run a separate audio cable from the audio out port on the MacBook Pro to the audio in port on the TV.
Check your MacBook Pro model year against the list in this Apple tech note:

How to connect my Macbook Pro to HDTV Polaroid with Audio

I connect my cable mini dvi in my macbook pro to my screen Polaroid 40 "I have video but I have not audio, and I went to the System Preferences menu to change the audio output and can not hear anything on the screen
thanks

The yellow RCA jack is called "NTSC Analog Composite Video", or "Video" for short. You need an adapter to "Video".
Exactly which MacBook Pro (or which output Display Port) do you have?
