Question about audio in FCP

When I import an audiofile that is mastered to -12dbFS the meter in FCP shows about -18db..
Why?

how was this file mastered?
when i record a clip with -20db tone, and then import that into fcp it registers at -20db, exactly as it should

Question about audio channels in FCP

Because of the way audio was captured with a few clips in my sequence, the clips audio is only coming through one channel (speaker). The other channel contains nothing. How can I duplicate the channel with audio and assign it to the other speaker?

I did notice that. There are a small few of us on here.
So now that I've helped you out, bring me some Great Plains Sauce & Dough.

A few questions about audio player in iBooks Author

1. How can I set the player to a small icon in Landscape layout? It seems that I have to display the player in the Landscape layout and show a big icon (which can't be resized) in the sidebar of the Portrait layout. Is there a way to customize this?
2. I notice that the audio player in iBooks Author looks different from that in the actual iBook on iPad?
In iBooks Author it's silver, which looks pretty nice:
But in actual iBook on iPad it becomes black:
Is it possible to customize the look of the player?
3. Another problem about the player in the actual iBook on iPad: When I have multiple players on the same page, only one of them shows the progress bar and time; others just show a play button:
If I click the one which only has a play button, the whole player will disappear (and won't play the audio clip). I must click the area (which the player is supposed to be in) again, and the player will show up with the progress bar and time (and other players will only have a play button).
This is very annoying. Does anyone have the same problem?

assuming you have a MovieClip mc on stage with the registrationpoint in the center:
stage.addEventListener(MouseEvent.CLICK, zoomHandler);
var currentZoom:Number = 1;
var zoomFactor:Number = 1.1;
var maxZoom:Number = 2;
function zoomHandler(e:MouseEvent):void{
    var zoomCenter:Point = new Point(e.stageX, e.stageY);
    var mcCenter:Point = new Point(mc.x, mc.y);
    var _xCorrection:Number = mcCenter.x-zoomCenter.x;
    var _yCorrection:Number = mcCenter.y-zoomCenter.y;
currentZoom +=zoomFactor-1;
if(currentZoom<maxZoom){
    mc.scaleX +=zoomFactor-1;
    mc.scaleY +=zoomFactor-1;
    mc.x -=_xCorrection*zoomFactor*.5;

Question about Audio line-in/optical in/Audio out/optical out

I have a late 2009 27" iMac (v3.06 GHz Intel Core 2 Duo). I note that on Apple's description of the rear ports, what I thought were simply headphone (Audio Out) and microphone (Audio In) jacks are described as:
1. Headphone/optical digital [S/PDIF] audio out:
"Line/Headphone output
"The headphone output is automatically selected for audio output if no external S/PDIF optical digital output device is detected. The headphone output supports a stereo data stream at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. The headphone output volume can be adjusted from 0.0 dB to -64 dB..."
"The headphone output is automatically selected for audio output if no external S/PDIF optical digital output device is detected. The headphone output supports a stereo data stream at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. The headphone output volume can be adjusted from 0.0 dB to -64 dB."
and
2. Audio line-in/optical in:
"Line input
"The analog line input operates independently from all other audio input ports and is always available. The line input supports recording at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. Audio recorded from the line input is presented as a stereo data stream. You can adjust the line input gain from -16 dB to +30 dB..."
"The digital audio input has the following electrical characteristics (nominal specifications), based on input of a 1 kHz sine wave at 0 dBFS input level, 24-bit sample depth, and 44.1 kHz sample rate (unless otherwise specified below):
FSI – input sample rates: 44.1 kHz, 48 kHz, or 96 kHz
Bits per sample: 16, 20, or 24
Signal-to-noise ratio (SNR): >130 dB
Total harmonic distortion + noise (THD+N): <-130 dB (0.0003%)
Sound output/digital audio output port"
While, as an Olde School audiophile guy (62, and I still have vinyl!), I generally understand the gist of all this, I'm not at all hip to what S/PDIF optical digital output and/or digital audio input can do for me. So my questions are:
1. Can somebody please wise me up to the usage(s) of these optical inputs and outputs on the iMac?
2. The Apple description says,under "Line/Headphone output":
"PCM: 16, 20, or 24 bits per sample at sample rates of 44.1 kHz, 48 kHz, or 96 kHz
AC-3: 16 bits per sample at sample rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, or 192 kHz"
and under "Line input
"The analog line input operates independently from all other audio input ports and is always available. The line input supports recording at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. Audio recorded from the line input is presented as a stereo data stream. You can adjust the line input gain from -16 dB to +30 dB."
How -- where -- do I adjust these bit depth and sample rates?
Thanks for your help!

Thanks for the info. Turns out there's an even easier way to do it than using the "Audio Midi Setup": through the prefs in the latest (and probably some previous) version of VLC, which is currently Version 1.0.2 Goldeneye (Intel 64bit).
Now if we could only get full native resolution (or at least 1080p) HDMI input into the Mini-DPs of our 2560 x 1440-capable 27" iMacs and actually have it display something WAY better than 720p (half the resolution of which the 27" iMac is capable) to which Apple limited it, without having to buy a third-party $270.00 HDMI-to Mini-DPP converter and scaler. Call me crazy, but it seems kinda silly to have to pay another $300 to buy a device that will scale the 27" iMac's resolution back up to a measly 1080p, let alone its native 2560 x 1440. But, as the
As a side note, can anyone tell me -- perhaps the elusive and chimerical, but omniscient and omnipotent "communityhosts" of Apple.com -- why, in my original post in this thread, the phrase "1. Headphone/optical digital S/PDIF audio out" had the acronym "S/PDIF" stricken through, like it was a particularly egregious Anglo-Saxonism? Wikipedia defines the acronym thus: "S/PDIF is a data link layer protocol and a set of physical layer specifications for carrying digital audio signals between devices and components over either optical or electrical cable. The name stands for Sony/Philips Digital Interconnect Format."
If I have inadvertently broken another arcane, abstruse, and/or inscrutable canon of the rules (http://discussions.apple.com/help.jspa) governing what may or not be asked or said on these avowedly "user-driven" discussions, allow me to beg for forgiveness beforehand, pleading ignorance, and ask that Apple's "community hosts" or administrators would expand upon and make very clear, in their "Apple Discussions Terms of Use," a comprehensive list of terms, subjects, lines of discussion, references to certain items, products, people, policies, etc. that are simply disallowed in the forum.
It is extremely depressing and frustrating to spend however long it takes -- and it takes ME a long time, as I have a 60-year-ingrained tendency towards verbosity -- to ask and post a question or message, only to have the message never even posted to the forum, but, without any sort of consultation with me so that I may learn from, and correct, my errors, uncaringly consigned to the illimitable void by hands to whom there is no appeal or orison.

Two questions about Audio Tracks

I need to make several adjustments to an audio track of an interview to remove the voice of the interviewer who would give the occasional "uh-huh" etc., sometimes overlapping (though usually not) with the interviewee.
The way I've been doing this is to pull down the db level at those points in the timeline.
My questions:
1. Is this the best way to do it?
2. Regardless of the answer to question 1, why is it that sometimes when I use the pen tool in one stereo track, it will automatically affect the other at the same time, and other times I need to do each stereo track separately?
Thanks a lot.

If you recorded with two mikes, which it sounds like you did, you really recorded two distinct tracks, and you ought to bring them in as dual mono tracks, rather than stereo. (A capture setting.) Go to the Modify pulldown and uncheck "stereo pair." Then you should be able to adjust to your heart's content.
Did you record any room tone? It's very useful to fill in the gaps you create by eliminating words. Nothing detracts from an otherwise compelling show like bad audio! If you don't have any room tone, look for a section where no one is saying anything and there is no clothing rustle, etc, FROM THE TRACK where you are making deletions. Use that to fill the holes.

I have questions about audio timing and volume levels

I have a question regarding editing the audio timing. There are a few section in my clip that the rythym is a split second off. What technique can I use to sync up the time by just a fraction of a second?
so far I've tried use the re-time editor which I thought was gonna work but after I re-timed the section, I couldn't drop it back into place without having the lower clip change and make things more confusing, but I had a feeling I was doing thing right for a second. Was I on the right track or is there another way of doing this?
on another note...
I have some sections in my clip that are peaking in the red, but sound fine on my computer even at full volume. I hear no distortion at all. Does this pose as a problem, and should I re-adjust?
how to connect cuts in final cut pro

This is actually a somewhat complicated subject. There are actually several different kinds of sync issues. Two major "classes": 1) some audio seems to speed up or slow down over time compared to other audio, and 2) audio that just needs to be aligned in time.
One of the biggest culprits for sync issues is mixed bitrates. A typical FCPX project should default to an audio bitrate of 48kHz. If you have 44.1kHz (or other bitrate) clips, mixed in, the first thing you should do is make sure all your audio clips are conformed to your project.
Select your clips and then select:
[Note: when retiming clips, even if only slightly, make sure Preserve Pitch is selected.]
If that doesn't work, or your audio is "live" recordings and you'd like to tighten up performers timing a little, you can manually sync audio tracks to each other. (You should have at least one audio "track" with the best timing to be your "beat track".)
The idea is to find the events you need sync'd in the audio waveforms; which means listening and seeing the pattern in the waveforms (turning on "scrubbing" helps); and you should find these indicators as close to the end of the clip as possible (you will need to zoom into the clips to see them clearly enough and you will need room to access the retiming slider on one of the clips... so... near the end is best.)
Zoom into the audio clip on the storyline so you can see the waveform clearly, but not so far as to lose detail in the "subsample" range -- to start (it's very difficult to distinguish specific peaks if you zoom in too far.)
With the audio clip selected and the playhead placed on the start of the "event" (bass beat, tom/snare hit, cymbal, etc.) type the M key to set a marker (markers on audio clips can be set on subsamples, so it will be "inside" a single video frame range.)
On corresponing clips that you want to sync with the "master" clip, do the same thing: select the clip, find the corresponding "event" start for that clip, move the playhead to the beginning of the event (you might have to zoom in [command- +] on the storyline one or two times more to improve the resolution), type M to set a marker.
You now have two markers you can align by retiming one (or more) of the clps to match the "master". Use the playhead and have it 'snap' to the master's marker. When you retime the others, visually align their markers to the master's by using the playhead as a visual indicator for alignment.
This technique can be used with video and audio that has gone out of sync, by finding the visual indicators of a specific sound in the video, setting a marker to mark the start of that event, then finding the audio event and setting a marker. You will need to detach the audio from the video first if you're going to work on it in this way.
It's even easier to sync audio if there are no retiming issues (that is, you just need to align clips, not retime them.) Find the position markers as in the description above (anywhere in a clip since retiming is not necessary), turn on snapping, drag one of the clips until the markers snap... and you're done. You don't even need to use the playhead to have the markers snap to alignment with each other. Very convenient for adding foley/sound effects to video.

Question about audio in and xbox360 audio on the x-fi audio c

I am having an extremely difficult time getting my audio to go from my 360 through the card. I have updated everything and still can't get any audio. I actually had audio for a day or two and then it stopped and I have no clue why it started or stopped.
I have my 360 hooked up to my monitor through the vga adapter and the audio is plugged into an adapter that goes to a single cord that plugs into the back of the card.
I had this previous settup under windows xp on another motherboard and the audio worked fine. I installed vista on a new mb and the audio wouldn't work with onboard so I bought the card. I get the same issue with the card although it did work for a few days as I said. Then it just stopped working and I hadn't touched any audio setting directly.
I've gone through all the audio setting I can find and have tried switch things on and off under sound which lists speakers and digital audio interface under playback. The audio from winamp goes through the digital audio interface (I can see the sound bar going up and down on it.
There's another tab that says recording and includes s/pdif-in, line-in auxiliary and microphone. All of those are unavailable except for the microphone. I've tried switching to the other devices and none of them have made the 360 audio come out.
I've also checked the hardware configuration under hardware manager and the device is working fine. I'm sure it has something to do with vista because everything worked under xp before.
Anyone else have this issue before? It kind of sucks that I can't play audio from my 360 to my speakers. I'm looking at installing linux on my other partition and see if it works through there....

Yep. I have the latest audio drivers for the card for vista and it was working. I was pissed because I couldn't get the audio working, then all of a sudden it worked and I have no clue what I might have done to fix that. I was playing bioshock for a few days and then I went one day to play it again, turn on my 360, and no audio at all.
It has to be either some audio setting, a driver issue, or some sort of incompatability in the software. Vista says the device is working and I do get audio out to my speaks from the computer so it has to be an issue specifically with the settings for the I/O jack, I think.
Like I said I had the same issue with my onboard sound so I bought the card. So i'm guessing it's some sort of vista setting. I'm just wondering what to check in the vista sound menu's. I have only just started using vista so I am not completely up to date on vista. The sound menu seems far more robust in terms of devices displayed and such.

Newbie Question about Markers from FCP

I'm trying to make markers, compression markers and having problems. I was able to make the first which was at a fade out and then in to the next sequence, but when I tried to create the second marker in the same way, it didn't work. Also, do I need to make chapter markers if I'm making one movie that will not have any menus. The dvd should just open and play the video right away and then continuously loop. So, I thought I should just make compression markers where there are edits and fades. I've been reading the manual, etc., and I'm confused. Sorry, but anyone who can help would be greatly appreciated.

The compression markers are really only there to signal to Compressor that a new GOP is needed at that point, because there is a sequence which requires special treatment during the encoding process. They don't carry over as markers into DVDSP's timeline.
You don't need to add markers to anything in FCP if you are not setting up chapters on the DVD. Even if you are, you can still add markers from within DVDSP if you then find that you need some (although they rarely get frame accurate placement once in DVDSP).
When you import the footage to DVDSP and add it to a track there will be a single marker at the start of the track - this is normal, and necessary! Don't try to delete it.

Question about FCP settings

I must have changed something in my settings accidentally because for some reason whenever I drag a clip into the timeline, the the audio is not linked together and I always have to highlight the tracks and link the selection. What can I do to make the audio tracks be linked together by default?
By the way, im talking specifically about audio here--not about linking audio to video, but linking two audio tracks together.

Question about Z87-GD65 Gaming 7.1 HD Audio

Hi, I am interested in the new Z87 GD65 gaming motherboard, it looks cool but I have a question about the 7.1 HD Audio.
Does it only support through S/PDIF output? or, by using the Sound Blaster Cinema suite, it able to simulate virtual 7.1 surround
to my Stereo headset, just like other standalone 7.1 virtual sound cards do?

Follow up question. importing audio

Hello,
thanks to all that responded to my question about importing audio from itunes to FCP5. I finally got it onto my timeline, but before I did that I burned it to a cd, and used that to import it to FCP. Probably more steps than necessary, but I finally was able to get into the timeline that way. THE PROBLEM HOWEVER, is that the audio sounds scratchy, or slightly staticy (wierd word) I burned it in 48kHz and 16 bit AIFF,as you all recommended, but it still sounds crappy. Anymore suggestions?? Could disc space be the problem?
I have a huge project going and only about 10 gigs of space
THANKS,
Jen

When you buy a song, or a CD, you bought the right to listen to that song to your hearts content. Make as many copies as you want, but only for YOU. Your song. Play it at a party..fine.
But put marry that song with video, and you have entered new territory. To do that you need to buy additional rights. Just like you'd need to buy rights if you play music at a wedding, or play music for people to listen to when they are on HOLD at your business.
Adding it to family video is "technically" illegal. Will the FBI hunt you down...well, after the government went after a lady for owing $1.16 in taxes by siezing her house, I wouldn't be surprised.

Questions about using the Voice Memos app

I'm currently an Android user, but will be getting an iPhone 6 soon. My most used app is the voice memos app on my Android phone. I have a couple questions about the iPhone's built-in voice memos app.
-Am I able to transfer my voice memos from my Android phone to my iPhone, so my recordings from my Android app will show up in the iPhone's voice memos app?
-When exporting voice memos from the iPhone to computer, are recordings in MP3 format? If not, what format are they in?
-In your opinion, how is the recording quality of the voice memos app?

You cannot import your Android voice memos to your iPhone's voice memo app. You might be able to play the Android memos and have the iPhone pick up the audio and record it.
Here is the writeup about sending voice memos from the iPhone to your computer (from the iPhone User Guide):
App quality is excellent.

Questions on Text in FCP

First let me thank all of you for the help over the last few days while im doing a student project on FCP which im taking a class for and learning.
OK, I need to do, as a assignment, like a text/graphic based car commercial. How can I change the color of the background that the text goes on? When I just select text it has a black background with white text. Also, when I highlight just a portion of the text it doesnt seem like I can adjust the font size just on part of the writing in the canvas (hope that makes sense). And how the heck do I pick a font, anyone got any cool ideas for font that kinda jump off the page?
thanks

In FCP's basic Text generator, you can't selectively alter font size, everything has to be the same.
(the link provided should also answer your question about the 'black background' and introduce you to the Matte generator
To get around the single font size issue - and give yourself more choices for the cool font that you're looking for - press Control-Option-X to launch the Boris Title 3D text generator in the Viewer. Then see what your mind comes up with.
Good luck.

Questions about editing with io HD or Kona 3 cards

My production company is switching from Avid to Final Cut Pro. I have a few editing system questions (not ingesting and outputting, just questions about systems for the actual editors - we will have mac pros with either kona 3 or io HD for ingest and outputs)
1) Our editors work from home so they most likely will be using MacBook Pros - Intel Core 2 Duo 2.6GHz 4GB computers with eSata drives to work on uncompressed HD, will they be able to work more quickly in FCP if they are using the new Mac Pro 8-Core (2 Quad-Core 2.8GHz Intel Xeon) or will the mac book pro's be able to hold their own with editing hour long documentaries, uncompressed HD
2) Will having an AJA Kona 3 (if we get the editors mac pros) or io HD (for the mac book pros) connected be a significant help to the editor's and their process, will it speed up their work, will it allow them to edit sequences without having to render clips of different formats? Or will they be just as well off without editing with the io HD?
I'm just trying to get a better understanding of the necessity of the AJA hardware in terms of working with the editors to help them do what they have to do with projects that have been shot on many formats- DVCPro tapes, Aiptek cameras that create QTs and P2 footage.
Thanks

1. with the IoHD, laptops become OK working with ProRes and simply eSata setups. Without the Io, they can't view externally on a video monitor (a must in my book). It will not speed up rendering a ton, nor will it save renders of mixed formats. The idea is to get all source footage to ProRes with the Io, and then the Io also lifts the CPU from having to convert ProRes to something you can monitor externally on a video monitor, and record back to any tape format you want... all in real time.
2. Kona 3's on Towers would run circles around render times on a Laptop... no matter what the codec, but the Kona does not really speed renders up. That's a function of the CPU and just how fast is it. (lots of CPU's at faster speeds will speed up render times).
I'd recommend you capture to ProRes with Io's or the Kona 3 and don't work in uncompressed HD. You gain nothing doing it quality wise at all. And you only use up a ton of disk space (6 times the size in fact) capturing and working in uncompressed HD, which from your post, you're not shooting anyway. The lovely thing about ProRes is that it's visually lossless, efficient, and speeds up the editing process. Mixing formats can be done, but it's better to go to ProRes for all source footage, and edit that way.
With either the Kona or the Io, you then can output to uncompressed HD tape... that's what they do for you no matter what codec you've edited in. ProRes is designed to be the codec of choice for all HD projects when you're shooting different formats especially... Get them all singing the same tune in your editing stations, and you'll be a much happier camper. Only reason to buy laptops is portability... otherwise you're much better off with towers and the Kona 3 speed wise.

Few questions about Lenovo G550

Hello, I plan to buy an inexpensive laptop, propably it will be a Lenovo G550L but I got few questions about this model. Here are my questions:
1. What 320GB hard disks are mounted inside G550L, Western Digital, Seagate or Hitachi (exact model if possible)?
2. How are the hinges of LCD screen in this model, cause they look pretty weak. Do they break easy, does anyone got any experience with this type of hinges which are "forward type" instead of normal?
2. I have noticed that there are two types of laptop chassis in this model one is matte black and another is grey glare. How to determine which model has which finish? Which finish got laptops with T4300, 3GB RAM, 320GB HDD, Intel IGP x4500, no card reader, no hdmi.
Thanks in advance.

my friend samsung any net, toshiba regza link, panasonic viera link is their special TM to support CEC
but just for their product not other products,for instance a samsung dvd player and a samsung lcd can sync easily with with hdmi cable
and in this case you dont need an extra remote control to control dvd besides tv.just with having a remote you can control both of them or the other audio visual products from that campany
please think???? how could you control your lenovo when it does not have a remote?
every device need to send signals to the remote not by just some wires like HDMI
lcd has a remote and a dvd player also has a remote and if those are from a unit company,they share a common signal with HDMI cable ,then you could control both of them with just one remote.
this can ease your work,as you dont need a lot of remote around your devices
but they should be from just a unit producer cause they uses different protocols
and of course they want to sell their various products and oblige you to buy other products from that producer to have the compability for having just one remote.
