Audio filter have no effect

I am an audio engineer who is a newbie to Final Cut. I am having a problem with the audio on a music video I'm doing for a client. The situation is this: I select an audio clip in the timeline that I want to apply an audio filter to. So I double click it so it shows in the viewer,then go to the Effects tab and choose an audio filter, which then appears in the viewer under the Filters tab. All well and good. But then when I make changes to the filter parameters I do not hear changes in the audio, and that's the problem. I have tried dragging the Filter from the effects tab directly to the clip in the timeline- same thing, nothing happens when I make changes. Of course I tried making radical changes which should be very apparent, but I still hear no changes. What am I missing here?
Thanks,
Monte

Yes, you're finally getting the right impression. I know very well what you mean though. I work with pro tools all the time and I love that all the effects are real time. Final Cut is a whole different story. Usually if I need to do anything more with my audio other than apply a compressor or gain I take it to SoundtrackPro or ProTools. FCP is terrible with audio. And yes, you have to render both audio and video. (In your settings you are able to change how many tracks FCP can play at the same time but doesn't seem like you got that many anyway).

I do not have to render in order to hear them, but there is an annoying beep until I do render.
If you're hearing that beep then that means that you DO need to render. Exporting from Garage band and ProTools has never been a problem for me. Maybe you have some really weird timeline setting. Mind sharing those with us? In the future, it's always best to work in a ProRes timeline.

FCP renders audio pretty quickly. Deleting the audio render files is not counter-productive because fcp will render those in no time and this time they're be playing right. Sometimes I need to do that a few times per project. It's annoying as **** but when you're not working in a native fcp format you're pretty much setting yourself for a disaster so that's the price you're gonna pay!
And yes, all of the audio will be rendered eventually before you export.

Which audio filter to remove low rumbling sound

Can someone tell me which audio filter is most effective in removing air conditioning rumbling sound from video? I searched older posts but can't find the answer, and I'm not experienced in audio filters. Thanks in advance!

I recommend using the noise reduction tools in SoundTrack Pro. Or, if you want to stay in FCP, use an EQ filter and/or a high pass filter.

Audio filter: flat

Hi:
Is there a good audio filter in FCP that can help reduce the echo effect of a
church? It's hard to understand the speaker because of the magnificent echo
created by the sanctuary. I'd just like to be able to reduce that a bit.
Any thoughts?

Hi, this is an age old problem that I'm afraid your stuck with. Many people believe that audio problems are solvable in post production but if you have recorded it then your stuck with it. Usually only buzzes and hums are removable and not always successfully.
I suggest you try experimenting with filters and see if you can improve the sound quality. EQ maybe, but even try a harsh compressor, you never know. There are some noise filters that sample the background noise and then remove it but they tend to make the person sound like they have a speech impediment.
The only real way to solve the problem would have been to get the mic very close to the speaker but in an echoey church even that may not be the answer.
Sorry there is no straight forward answer to your problem.

Best audio filter for heavy wind noise ?

Hello everyone
I'd like to know what is the most used audio filter in order to recuce a heavy wind noise without affecting the voices of a conversation in my movie ?
Thanks

I don't know what people use, but I've always been told that the best way to get good audio is to get it right the first time. Since I'm no sound guy, I struggle to get anything to sound good.
Export your offending Audio to .aiff and pull it into SoundTrack. Go to your Effects on the middle left of your screen and pick SoundTrack Pro>Channel EQ. Drag this into the area under your Effects bin. Then start playing your sound while adjusting the Advanced Dialog.
You can tweak different frequencies and try to pull out the wind. However, wind often is around the same range as voices, so it's going to cause some distortion.
Beyond this, if the wind was really bad it will have caused "popping" that will have mutilated any talking at that moment.
Can you do any looping/re-record the voices? That may be your best bet.
I'm hoping some sound guy comes here and sets me straight and helps you out. Perhaps check the SoundTrack forums....
I'm sorry I'm not more help.

Audio filter in real-time---help!

Did you ever make great progress using a program, and then were unable to duplicate that success the very next day? I sure hope so =-because then I know I'm not alone.
THE SUCCESS-Finale Cut Express--hum filter--by using the feeble instruction manual I was able to adjust the hum on a portion of my movie as it played (listening while you adjust is the only logical way to do it).
THE FAILURE-I can't duplicate this success on the section of the movie.
I believe I am following the same procedure as before, dragging the hum reduction filter to the clip, double clicking the clip, clicking the filter tab so the hum parameters are visable, moving the playhead to the clip. When I play the clip, the hum filter controls have no effect on the sound. But of course, when I'm done having no effect on the clip, the clip needs to be rendered again!!!!!
I can only guess that something was set differently in the program when I tried it the first time. I've now tried it so many ways that my toes are numb.
Can someone walk me through this action with instructions on how the prefs or other program parameters must be set before hand? Thanks.

Joe

AUDIO constantly needs rendering:
I believe the exporting of my iMovie audio files for importing into FCE spolved the rendering problem of having to render the audio continuously. However, it seems as though the more filters you use as well as the kind of filters used, will eventually cause you to have to render.....and with each successive change, rendering again.
AUDIO FILTERS WORKED the first time, and then didn't work the second time:
Unless you work with FCE for a long steady period wierd things continue to happen--because you, yourself, probably did it.
With the HUM remover filter I was working with, the box was checked (filter was active) on both occasions. On the second occasion, however, I checked none of the harmonics boxes!! It may have been that the frequency I used was different than the first time. Meaning the "Q" slider (another mystery) had little or no effect with this particular frequency--UNTIL I FINALLY CHECKED ONE OF THE REQUENCY BOXES.
OR
I just plain forgot that I checked those boxes the first time and should have checked the the second time as well
THANKS AGAIN,
Joe

Audio Filter missing: Internal Volume Stereo - corrupt project?

Hi,
I am getting this error when I open my project. In addition, no media will play in the project either in the sequence window or the source window.
It all appears and will scrub (with no audio), but will not play.
I dug around a bit and I found that there is a known bug with audio from XML's and that is what I am using (convinced my client to migrate from FCP to Premiere - please don't tell me I made a mistake).
Everything worked brilliantly for a week, including the addition of audio filters, and then all of a sudden - bang. No more.
I have painstakingly deleted every audio filter and I am still getting this error. I have also tried a re-install.
Another oddity is that when I try to quit Premiere, it will not quit all the way without a force quit!
I'm running CC 2014 on a brand new mac pro.
Desperate,
dw

Steve and Bill,
I follow your advice, but it did not solve the problem. It is true that problems began when I used ZOOM recorder at 98kHz/24 bit in my current project (I already changed ZOOM mode to 48kHz/16 bit), but could this be just a coincidence?
In the meantime I checked the rest of my 16 projects (.prel), which were fine before. To my surprise I found that although all of them were made using EXACTLY the same method, some of them are still OK, but most I can not Playback. The messages appearing are of three types:
1. "Audio Filter missing: Internal Balance".
2. "Audio Filter missing: Internal Volume Stereo".
3. "This type of file is not supported or required codec is not installed".
In one case, when I opened a project the first time, the message was "This type of file is not supported or required codec is not installed", but when I opened it second time it said " Audio Filter missing:Internal Volume Stereo". It seems to be random.
Some projects can be opened, but when I try to Playback there is no sound.
I am completly lost. Please help.

How to install plugin and exta filter in photoshop cs ? and any special filter for special effects ?

how to install plugin and exta filter in photoshop cs ? and any special filter for special effects ?
kindly recommend me any best one and tel me step by step how i will add more plugins n filters

A Plug_in normally come with an installer or install instructions. Check the documentation for the plug-in you trying to install. It sounds like you don't know what plug-ins you want to install. In that case you don't need to install any. At some point you may read about a plug-in and what it can do and feel you have a need for it. Then you will have a reason to install a plug-in that is not installed by default. There may also be a cost involved most worthwhile plug-ins are not free.
Adobe Optional Plug_ins downloads are Plugins Adobe want to remove from Photoshop and no longer install by default. Also at some point in time these will no longer install into the current Photoshop for Adobe will remove feature or interfaces the use. For example the CS5 optional plugins will install in Windows CS6 perpetual version 13.0.1.3 but not in Subscription version 13.1.2 or perpetual Mac version 13.0.6 fot its 64bit only and the Mac CS5 optional plug-in for Picture package is only a 32bit plug-in.
You will need to keep and maintain old versions of Photoshop if Adobe remove features you use in new versions of Photoshop.

LR5 's Adjustment Brush doesn't seem to work-does the New Radial Filter have priority?

So why in the world would I update Lightroom in the middle of a job.?
Before I was able to do in and touch up shadowy areas using (K) adjustment brush, but now it doesn;t seem to work. The radial brush does a good job for a defined area but for SPOT touching I have always used the the adjustment brush?
Is there a setting or am I missing something or is this a bug?

The presence of the Radial Filter in the tool set should have no effect on the Brush. It continues to work just as it always has. In fact, even if the RF is open (I sometimes hit it by mistake when I really want the Brush) and you click on the Brush icon, the RF closes and the Brush opens. If your Brush is not functioning properly, it is very unlikely that the RF is the reason. The usual first aid for any LR misbehavior is to close LR, remove the Preferences file from its folder and relaunch LR, allowing it to make a new preferences file. Not guaranteed to solve the problem, but worth trying.

What kind of audio filter would i use.

i need an audio filter that will bring out a distant clapping noise thats you cant even hear during playback. i have raised the dB as high as possible. is there a way to get it heard at all?

Just be aware, that if the audio is very slight and you raise the level .. you will also raise the levels of any surrounding room noise, etc ... so you will get a lot of hiss and maybe even echo. You can also double up the clip to increase the volume but I doubt you would be left with anything useful
Been there, done that, cursed the cameraman

Severe audio problems in After Effects CS4 and MXF and more...

Hi!
I've been experiencing a lot of problems lately with several CS4 products.
First, and the worst, is that there seems to be some severe audio bug in After Effects when handling mxf-files. I pre-cut a project in premiere CS4, shot with a Sony EX1, and then imported the project in After Effects CS4.
In premiere everything worked fine and I had all the audio. In AE however the audio matched with the MXF-files disappeared (Yes I had the import audio box checked). All other audio worked fine from the music tracks and so on, but the MXF-files (MXF for NLE) was completely blank, the waveforms were completely flat. I checked every option there is in AE regarding audio and tried enabling and disabling XMP ID's and so on. After a lot of tweaking and testing I understood that the problem was not with any settings anywhere, the MXF-files lacked audio even if I started a new project and just imported the MXF-file.
The problem seems to be connected to when importing from Premiere. My colleague was editing a similar project on his computer in After Effects without problems, and he started out fresh in AE (didn't pre-cut in premiere). However, we tried to move my project to his computer, to see if the problem was connected with incompability with my hardware or such, and he got the same problem as me when he opened the project. Waveforms on MXF-files were completely flat. Certain confirmation that the problem was not connected with my computer appeared when he later reopened his own project, that had worked fine before, and audio was now completely gone - waveforms flat. An hour later, by chance, his audio suddenly popped back.
I have experienced this problems in two different projects in different forms (but both pre-cut in premiere). In the first, audio disappeared while previewing but was there when I ctrl-scrolled and rendered (no I hadn't muted audio in the preview panel). In the second, audio was completely gone even when rendered.
In both cases I tried saving and restarting the computer, reimporting from premiere, starting a fresh after effects project and only importing the mxf-files, changing the project settings, fps fixed to the correct instead of auto, changing output audio mapping, changing XMP, and so on in every possible way and combination I could imagine.
At my company our suspicion is that After Effects flags mfx-files imported from Premiere in some wierd way, to strengthen and ensure compatibility between the two - regarding different audio tracks, settings and effects from premiere (and this is almost what you could suspect that the XMP ID is for, but as explained with or without doesn't change a thing regarding this). We have no problem with the pure MXF support for AE, as MXF-files work just fine in After Effects if you import them directly and have not imported them through premiere earlier (but after a file has been "flagged" you seem to be sc***ed)
Anyone else experiencing this? Or am I missing something huge?
As additional notes, the dynamic link function seems extremely buggy and both premiere both sometimes complains about "dynamic link already in use and only one connection blah blah" even though only one link is used, and even though you restart the projects, programs, computer, whatever.
In furher addition Adobe Media Encoder (which also seems to be using some sort of dynamic link offspring) is super-buggy and most codec formats either doesn't start to render or just renders partially and then the program hangs. The problem have a connection with a process named pproheadless.exe eating upp all the RAM (4gbs).
(My workstation has been working smoothly for one and a half years and I have had very little problems with CS3 and "just" AE CS4. I am cautious of updates, don't have spyware and use Quicktime 7.5 as 7.5.5 is superbuggy and people seems to have problems with 7.6 and it doesn't fix the gamma issues anyway.)
Sorry if this was a long post but the problem is compl

Dude, that's what these forums are all about. Everyone in here says they dont work for Adobe, but they all act like apologists for what is clearly a disaster of a software release. My complaints aren't as specialized as yours, just very basic, and I wont go into all of them, because the list is long, and includes nearly every program in CS4.
I'm going for a refund, either from the retailer or my credit card company. Releasing software like this is dishonest.

Can't access Filter-Render-Lighting Effects

I have an image in Bridge that exists both as a jpg and camera raw. I can open the jpg version and apply Filter - Render - Lighting Effects. When I try to do the same with the camera raw image, I get as far as Render, and then the Lighting Effects options is gray and not accessible (along with Clouds and Difference Clouds). Why is this? Surely it should be possible to use the Lighting Effects feature with a raw image?
I am using CS2.

Glad to get you up to speed again, on only took a few min. to get answer. Your lucky day!

*** Audio filter to boost low volume?

I have a clip that was recorded at too low of a volume. I would like to now augment this in post. Is there an audio filter that I could apply in FCP that would increase the speaking parts and at the same time reduce the hiss?
Thanks in advance!

The Dynamic Processor filter can increase volume, but sometimes it's quicker and easier to just duplicate the track [Shift Option drag]. For reducing the hiss I'd recommend the noise reduction process in SoundTrack Pro or applying an EQ filter and reduce the frequencies of the hiss.

Audio Filter NORMALIZE AUDIO

I have edited on all sorts of NE systems, and have found the Normalize audio filter in all. Does FCP have this feature, or is there any way to normalize (keep all audio levels within the same range.?)
Please let me Know!!!!
Thanks

I believe that is in Soundtrack but not infront of my system at the moment.
