Editing Stereo Tracks

Here's my situation; I want to be able to edit a stereo pair at the same time with all changes I apply to the left being applied equally to the right. I need to tweak some of the audio, take out background noise, adjust levels, etc. and my stereo pairs will only import into STP as two separate tracks. When I try to make changes to one track and then apply the same settings to the 2nd track it's too much and the audio sounds like crap. Not to mention it's twice as much work.
How can I get STP to make the audio I've imported from FCP show up as A1 & A2 (for example) on one track so that I can edit them at once and hear how the effect sounds when applied to both? It's just dialogue so I don't need stereo separation. The doorbell sound effect I'm using from STP shows as A5 & A6 in STP and in FCP it looks just like the other audio tracks (a linked stereo pair).
Background;
Some of the audio was recorded on one camera using a boom mic going into input one on the camera. So it was mono and I copied and pasted it to track 2 in FCP and linked it to make it a stereo pair.
The remaining audio was recorded on another camera using the on-camera stereo mic so it came into FCP as a stereo pair from the start.
Any help would be greatly appreciated.

I have Soundtrack and was wondering much the same thing. From your discussion it appeared that one could not split a stereo track into the two mono tracks and then work on each separately. However, upon reading the Help manual for Soundtrack 1.5 at page 167, it explains how one may export a stereo track as two mono tracks as follows:
To export individual tracks, busses, or outputs:
1 In the Timeline, select the tracks, busses, or outputs you want to export, then choose
File > Export > Export Selected [item].
The [item] shown in the menu changes depending on whether tracks, busses, or
outputs are selected.
If nothing is selected, each unmuted track, bus, and output in the project is exported as
an individual AIFF file.
2 In the Export dialog, choose the sample rate for the exported files from the Sample
Rate pop-up menu.
3 Choose the bit depth for the exported files from the Bit Depth pop-up menu.
4 Optionally, select the “Output dual mono files” checkbox to export the selected tracks,
busses, and outputs as dual mono files, then click Save.
5 Browse to the location where you want to save the exported files.
6 Click Export.
Each selected track, bus, or output is exported as a single stereo AIFF file or as a pair of
dual mono AIFF files. Muted and unselected tracks, busses, or outputs are not exported.
This might solve your problem because you can then import those two tracks back into soundtrack and work on them separately.
It worked for me.

Editing Separate Stereo Tracks?

Hey all-
I'm having a problem with FCEHD. I've captured some footage on my GL2 and I had a Beachtek DXA-6 hooked up to it with two separate external mics. When I import the video into FCEHD, there is only one track of audio. Can I split these two sources and edit each one individually somehow? (And yes, I made sure that I had the Beachtek switched to "Stereo" when I was recording). Anyway, any help would be great.
Thanks!

Thanks Tom, is there anything special I need to do to make the stereo tracks mono? (I can't play with it right now... not at home). I tried unlinking them, but that didn't work if I remember correctly.
Thanks again.

Stereo Track Showing as Mono Track in Edit View

I know this is probably something ridiculously simple :-)...but, I CANNOT figure out why a stereo track I'm working with is looking like a mono track in edit view.
What am I missing?

Yup...
Go to View>Waveform Channels and take the check out of 'Layered'...
Incidentally, the clue was that you have both channels displayed at the top of the screen - Layering is the only thing that will superimpose them.

Splitting stereo tracks to mono for separate editing?

Does anyone know of a way to split a stereo track into two mono tracks inside of Logic Pro 8?
I'll explain my problem, I have a track made from samples of a song. In the track that I recorded, there is one particular sound that I can't get rid of no matter how hard I try. I recorded the passage with the ESX24 in stereo and I noticed that the noise is only on the left track. My first solution was to pan the track all the way right, create a duplicate of that and pan it hard left. Unfortunately, it loses a lot of clarity and texture when I use this method..
Looking on the forums, all I could find was instructions to bounce the tracks to split stereo, but I need them to form separate tracks within Logic so I can apply a LowPass filter to the problematic left track, then mix them back together as one stereo track later....
Any suggestions?

You guys are talking about different things. The OP says he's using an exs24 instrument with a sample that has a noise on one side of the stereo field of a SAMPLE not an audio region recorded into logic. Samples used by the EXS24 are not added to the audio bin, only into the EXS24's RAM. You could pan the instrument track to the side without the noise, and then output the result to a bus track that is set to MONO. That will pan your one sided sampler back to center. You can also bring the sample into logic (using the browser) and then split it as eriksimon suggested, and then create a new EXS24 instrument using only the good side of the sample.

In Final Cut Pro X 10.1.1 I'm trying to separate left and right stereo tracks to delete left and pan right to centre. I cannot find a way to do this.

I record in stereo with a 10KHz tone down the left channel to defeat AGC on my camera and mic feed into the right channel. When I edit, I want to mute/delete the left channel and pan the right into the centre, to leave me with mono audio across both left and right. I could do this easily in FCP 6 but can find no way to do it in FCP X. I'm using the same source files. When I choose Dual Mono mode in the Audio Inspector, it mixes left and right and pushes the combined signal into both channels, giving me a mix of 10KHZ tone and audio in both left and right. Stereo mode shows me the two channels correctly with one driven hard (the tone) and the other at good voice levels. I just want to kill the left channel and pan the right to centre.
I'm converting original TOD files using MPEG Streamclip before import and definitely keeping audio as stereo.
This is driving me nuts! It should be simple and is in FCP 6. Any help greatly appreciated.
Stereo Setting
Mono Setting

Mb - If you're using FCPX 10.1.1 and Mavericks, make certain you've downloaded the most current Sony XDCAM FCPX plugin from sonycreativesortware.com unless you're using an older version of FCPX and then you'd need the previous XDCAM plugin.
You shouldn't see 8 mono tracks. There are import settings in /fCPX that you can check and I don't ask FCPX to analyze my media or seperate mono or combine stereo, etc. I like to have everything come in as it is, especially because I know what I've done with every channel, etc.
What I wrote to Ian is what I'd tell you - so please take a look at how you can make a "stereo" track that is actually two mono tracks, mono. Once you do that you can address each mono channel by itself since it needs different volume, compression, and EQ than other channels.
There are ethernet, USB, and firewire controllers that work in FCPX, but that's not the typical workflow because generally if you're getting into any amount of post audio sweetening beyond basic "staples" audio treatment, you would instead use "Roles" to export your audio to Logic or Pro Tools and do you work in those applications and then cut the final product back into your FCPX project. In Logic or Pro Tools is where you might use a controller.
In terms of automating levels, I'm not positive I know what you mean. Compressor is a nice internal Logic plugin that kind of automates levels in a way but its about compressing peaks at a threshold that you set and at a ratio of compression. So I may not understand what other automation is available unless you've exported you tracks to Logic or Pro Tools.

Soundtrack pro can't export stereo tracks

Ok. I have a problem. I'm recording some stereo cassettes into logic, then cleaning them up in Soundtrack. the editing flow is very usable. now, when I want to save, I have very limited options. Why can't I save as mp3/m4a/etc?? I see that export is what I need. Oh whoops, you can't export from a stereo track. Why?!!!?? Ok, so how do you convert a stereo track to multitrack to export? I could pretty much move completely over from Audition if I could figure this out. Help? I can't be the only one editing stereo masters in STP?

ok, how can I import stereo into two mono tracks? can files be moved from edit mode stereo into multitrack?

How do i export 16 mono tracks in a sequence as 8 stereo tracks.

Hi I'll be working with 16 tracks of mono audio in Premiere to enable flexibility with my audio edits but when i export i want to make those 16 tracks as 8 stereo tracks, as this is what our specs for TX are. So 1&2 will be stereo track 1, 3&4 will be stereo track 2, 5&6 will be stereo track 3 and so forth... In FCP this is easy as you can link and unlink the audio in the sequence, and in the sequence settings audio outputs dictate whether it will be mono or stereo.
From what i gather i can edit in mono sequence then copy and paste into stereo sequence, however as the audio tracks are 1 track whether it is stereo or mono how do 16 fit into 8 when pasting.
Sorry in advance if i am missing something very easy here, but im pulling my hair out with this.
Thanks in advance
Jason

PP wil naturally send a track to two channels, even with a multichannel Master. So you can ruote the tracks in the Mixer window.

Making two mono tracks from one stereo track?

I've used the M-Audio MobilePre USB device to record vocal and guitar at the same time. In GarageBand, this inputs as one track, with guitar on the left channel and vocal on the right.
I'd like to separate this one stereo track into two mono tracks for further mixing and editing.
Any ideas on how to do this?
Thanks!

Create 2 stereo tracks from 2 mono tracks

If I send a FCP sequence to a STP mulitrack project it opens with a left channel (A) as the on camera mic and the right channel (B) as the wireless mic. Since I want both to come through both channels I assume I should make the edits/corrections on both, then insert 2 new blank tracks. I'll then copy/paste each of the previously mono tracks so I have 2 stereo track, right and left A and right and left B. Does this sound correct or am I missing something here?

No. One work around would be to create a stereo sub mix channel, this would at least give you a single fader but it won't help you when editing. You could try grouping the video and two audio, then they should be easier to select.

Separating stereo tracks already on a timeline

I'm running CC 2014. I recorded all of my audio using a stereo track - there's a lav in the left and a shotgun mic in the right. I need to be able to adjust the volume of the channels independently.
My problem is that I imported all of my footage using the "use file" settings in the audio preferences panel in Premiere, and then I began editing.
I know that I should have imported the footage using the "mono" settings in the audio preferences panel, and when I import footage into my project after changing my settings to mono, my audio comes in as two separate tracks, which is what I want.
However, I can't find a way to separate the channels of stereo tracks that I've already imported and begun editing with. This is a huge problem, as I've already edited a 30 minute timeline and don't want to start over.
My question: is there a simple way to separate the audio channels of a stereo track already on a timeline into two mono tracks?
If not, is there a sensible workaround that doesn't involve shifting things around on the timeline and replacing clips one by one?
Thanks for your help.

I always recommend (and use) Richard's method, but you don't necessarily need to duplicate tracks to use it. If your intention is to use EITHER the left or right source audio at any given time and not combine them, then simply apply FILL LEFT or FILL RIGHT to the different cut up audio clips. For instance with a wedding video, Left audio is Podium Mic and Right is Groom's Mic. You would not want to mix/hear both at once - it is one or the other, depending on what it happening in a given scene. So just "activate" the source you want to hear for each clip.
I use a short audio crossfade between audio clips when switching between L and R source and this pretty much eliminates any noticeable jump in the audio. For footage that has not yet been edited (one long clip), use the Razor tool and just make cuts where you want to switch sources. Apply Fill effect to each segment as appropriate, with crossfade applied at cuts. Simple and clean results.

IPhoto or Final Cut bug: export creates 19 stereo tracks attached to file!

I am exporting three slideshows from iPhoto '08 to Quicktime to be placed in a Final Cut Pro project. The first two exported fine. The longest one (just over ten minutes) exports and plays in QuickTime, but when you import to Final Cut, it mysterious has 19 stereo tracks attached, and won't play unless you remove all of those tracks (hence, no music) Again, the shorter two come in just fine with one stereo pair, as you would expect.
I installed the iPhoto update, tried again, still the same thing...

Ryan:
Is it just that one particular slideshow or will any slideshow exported and imported to FCP display that problem? Also, if you have Quicktime Pro, open the problem file with it and check to see if if contains those 19 tracks. If not, then maybe FCP is causing the issue.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Is it poss to edit 2 tracks - mic&pickup, simultaneously in sample editor?

(I'm a total novice in Logic so it's easy to blind me with jargon) I've recorded a guitar with mic and pickup and want to be able to see and edit both tracks at the same time in Sample Editor. Any idea how? The manual says:
"If you’re dealing with an interleaved, or half of a “split stereo” file or Audio Region, both
channels/audio files will be displayed in the Sample Edit window, with the left side on
top, and the right side below."
Is there a way of interleaving my 2 tracks so I can do it this way? Or some other way? Many thanks in advance x

set your 2 tracks up the way you want in the stereo field - hard left and right if you want to be able to de-interleave them later....
Make sure everything else is muted.
Bounce the tracks using the bounce feature under the main out fader on logics mixer.
Your bounced track will be an interleaved stereo file which you can edit in the sample editor (as long as you choose interleaved stereo in the bounce dialogue box).

Imported clips has 19 stereo tracks mysteriously added. Exported frm iphoto

Hi, I posted this on the iPhoto section, but after thinking it over, maybe it's actually an FCP 6 issue...
I am exporting three slideshows from iPhoto '08 to Quicktime to be placed in a Final Cut Pro project. The first two exported fine. The longest one (just over ten minutes) exports and plays in QuickTime, but when you import to Final Cut, it mysterious has 19 stereo tracks attached, and won't play unless you remove all of those tracks (hence, no music) Again, the shorter two come in just fine with one stereo pair, as you would expect.

Lots to be excited about. BUT...Just updated to 8.1 on one of my computers to test it out...
Sadly, the following issue is NOT fixed for me. Is it with new projects only? I haven't started a new project on 8.1 I've only opened an old project but the issue that I'm referring to which involves also a delay/freeze of anywhere from a few seconds to a MINUTE while the render bar goes from yellow to red and then back to yellow is still there. Boo.
On the list above...
Switching between sequences can turn the render bar red.
This issue is incredibly easy to replicate. I really do hope it gets fixed. Here are the steps:
1) Create two sequences with multiple short clips (the more clips the better)
2) Make sure GPU acceleration is enabled.
3) Add warp stabilizer to the clips in both sequences. Again, the more clips the longer the delay/freeze will be as the render bar goes from YELLOW to RED and then eventually back to YELLOW again.
4) Hit SAVE.
5) Now, toggle between sequences. You'll hit a short delay with a few clips stabilized and a LONG delay with lots stabilized. In my case this delay is around a full minute. The render bar will go from YELLOW to RED and then back to yellow...eventually.
6) Toggle back to the original sequence and the delay occurs again.
7) Once you've toggled between sequences and have gone through this delay, that's it, there is no longer a delay...UNTIL...(and here's the big kicker)...until the project is SAVED again. After that the issue returns when you toggle between sequences. Both saving manually and AUTOSAVING cause this issue. No way around it except not editing with GPU acceleration.
Not sure what the issue is...caching issue when saving maybe? Either way, it stinks and it's still there in 8.1. Big bummer.
Again, lots to be excited about with this release but I really was hopefully this specific issue was resolved.
Sigh.

Imovie and audio - dealing with separate stereo tracks in imovie

The footage I am working with has stereo recording - a boom mike (L) and a lapel mike (R) were used simultaneously. However, I want to use only the left track that has the boom mike because the guy with the lapel mike is talking too much and drowning out the conversations on the boom mike.
I see that there are separate tracks playing in imovie but I see no way to use only the left or right track in the audio. What do I need to do? if iMovie cannot handle it, can I export the audio as a stereo track and edit it in Garageband, then re-import it?

Hi
if iMovie cannot handle it, can I export the audio as a stereo track and edit it in Garageband, then re-import it?
Yes - iMovie HD or other - Can't handle this.
Export out - as QuickTime expert mode and Audio only and as .aiff
Put it into an Audio editor - like GarageBand or Audacity (free on internet)
Edit it and save as .aiff
Re-import into iMovie and put on bottom track - silencing out top-track.
Done this many times -Works.

OMF importing Stereo Tracks are Seperate Mono?

Hey guys,
When you import OMFs into audition, each stereo track from FCP comes in on a seperate mono track. How do you make the 2 tracks that were originally stereo in FCP stereo in Audition so you dont have to make the same edit to the two seperate mono tracks every time? This is killing me.. Im reading about this mix pasting idea and making a new stereo file but I have to do this for every track that is imported into my multi track project?? I'm so confused. Anyone got any tips?
Thanks,
CRK Productions

As for mixing though in Audition, I have to make the exact same edit to both tracks? Im in CS 5.5. So if I keyframe one of the tracks from the "stereo pair" I have to go up and add another keyframe and mimic my edits to the other track? There is no way around this?
Yes, this is a bit of a snag... and one that for a completely different reason I ran into myself recently. The best solution I've come across so far (because it's free, and does exactly what it says it will) is Sound Devices' WaveAgent. Essentially, if you can easily decode into mono wav files, it will pack them into whatever format you want, all as one file. I use it to encode four mono files into one four-channel R64 file, which means that when you import it into Audition, it does exactly what you want - all edits occur on all four channels. It would do just the same for stereo.
