Convert Dual Mono to Stereo in Timeline?

I don't think there's a solution for this, but I'll ask anyway.
I'm in Premiere Pro CC.
Due, I believe, to the way FCP xml is read, any project I import from FCP, and any sequence I send to PluralEyes and back, has all stereo audio clips split into dual mono. The clips are still linked, are designated L and R, and play back correctly, but it's an organizational pain in the *** to deal with when all of my other clips are correctly in stereo.
Is there any way I can relink/combine/merge the split audio back into a single track? This seems like it would be an easy feature to add, so I don't see why it wouldn't.
Merge Clips and Nest are both greyed out. Under Audio Channels, I can only change the source channels; Channel Format is greyed out.
Thanks.

I've found to way to do this myself.

Convert dual mono tracks to stereo in Audition CC

How do I convert dual mono tracks to stereo in Audition CC please?

Sorry, but your intentions here aren't clear.
Do you have two mono signals on one stereo track, or are you talking about two separate mono tracks that should be stereo, and you want them as a single stereo track?
With the latter, open one file and copy it to the clipboard. Open the other file, and use Edit>Convert Sample Type to convert it to 'stereo' (really dual mono). Select just the side you want to replace, highlight it and hit Delete - this should leave your original file on one channel, and nothing on the other. Place the cursor at the start of the empty section and paste the clipboard contents here. Save the result. You now have a stereo file.
If you have a dual mono file and you want some stereo ambience on it, then have a look at SHEPPi. This does a remarkably good job of that on mono files!
There are several other ways of doing file combining - you could do it quite easily in Multitrack mode, and there are also some utilities around that will do it directly for you - although you could easily be forgiven for being completely unaware of them, because generally they are used for reorganising multi-channel Broadcast Wav files, and don't show up using a simple search term.

HT4589 How do I change the audio to dual mono from stereo when using Share to DVD in Final Cut 10.1?

How do I switch the audio to Dual Mono from Stereo when using Share in Final Cut Pro 10.1? Even though the audio is all in dual mono in the timeline, it lists it as stereo in the share box.

Hi rationale1,
Welcome to the Support Communities!
The share to DVD settings in Final Cut Pro X use the Dolby Digital settings which are stereo for DVDs. So this can’t be done directly in Final Cut Pro X.
The link below will explain the Dolby Digital parameters and options in Compressor 4. You may need to research a different DVD authoring software to achieve your desired result.
Dolby Digital - Compressor 4 User Manual
http://help.apple.com/compressor/mac/4.1/#cpsrb71736a2
Dolby Digital
The built-in Dolby Digital settings (in the Create Blu-ray and Create DVD destinations, as well as the built-in AC-3 and EC-3 audio settings) use the Dolby Digital transcoding format. This format encodes Dolby Digital (AC-3) and Dolby Digital Plus (EC-3) audio files that contain multiple audio channels, including 5.1 surround sound. You can also create custom settings that use the Dolby Digital transcoding format.
Note: All files intended for video and audio DVD authoring must have a 48 kHz sample rate as required by the DVD specification.
DVD Video: Choose this option if you’re encoding for use in a DVD video authoring application.
DVD Audio: Choose this option if you’re encoding for use in a DVD audio authoring application.
Tip: For stereo encoding, rates of 192 kbps and 224 kbps are typical and will produce good results. For Dolby Digital 5.1 encoding, a rate of 384 kbps is recommended. For 5.1 Dolby Digital Plus encoding, a rate of 192 kbps is recommended.
Cheers,
Judy

FCPX Dual Mono vs Stereo question

Hi everybody - I've been busy but recently on the Zumiez show I came out of it with a question:
I like to route each of my AJA KiPro ISO records two separate channels of audio, I send a line-feed to CH. 1 (left) and I run a NAT mic feed to CH.2, (right). If I bring the captures into FCPX, for example to create short lifts, I want the producer to be able to choose between the line feed or the ambient mic, so I leave them as "Stereo", but it isn't really a stereo track. I needed to adjust the levels, raise the line level and lower the mic level, but I can't do that unless I designate "Dual Mono". When I designate Dual Mono, I can adjust the levels seperately and even apply filters indivisually, but then the channels are summed mono.
How do you keep stereo seperation on two individual tracks and still be able to make individual adjustments? Or maybe another way to the same goal; can I set hard pans on a pair of Dual Mono tracks?
Thanks for any help! -Stephen

Can't get a clip to behave as Dual Mono

FCPX 10.0.9 is refusing to treat just one of my clips as dual mono.
When I right-click, show in timeline, it opens in a timeline with a single audio track showing.
For all the other clips / projects, right-click -> show in timeline reveals two separate audio tracks.
This clip was shot in the same exact way as every other clip. In fact, it was shot in between other clips that work.
When i select the clip, the inspector shows Channel Configuration - Dual Mono, in both the timeline and the event browser. Same as all the other clips.
If only I could slip the audio separately in the project timeline - but if I try, all I can do is select part of the clip - I can "Expand audio components" and see the two mono tracks in the timeline... but if I try to move them, all I can do is select parts of the clip, whichever tool I use. Can't move them separately.
Here's what I've tried:
1. trashing and re-importing the clip.
2. trashing and recreating the project.
3. doing both of those together.
3. duplicating the clip and importing that into a project. (this solved the same problem for another clip, but doesn't work on the current clip).
4. Quitting FCP and restarting.
5. Setting the source clip to stereo, back to dual mono, then re-placing it into the project.
6. Waiting for all the background rendering, wavefom generating, etc (this solved it for another clip that was refusing to be dual mono).
7. Copying the camera card to the hard drive and importing from there instead of straight from the card.
8. Importing the clip with "separate mono and group stereo audio" checked, then again with it unchecked
9. Opening the clip in quicktime pro 7 and changing the audio channels from "left" and "right" to "mono" and "mono."
10 quitting, renaming the clip in the finder, and reopening FCPX
One thing I notice is that through all theses steps, FCPX never has to re-generate the audio waveform files for this clip. It is seemingly remembering the clip and using a saved audio metadata set of some kind, which I think prevents me from solving the problem...
Dang! I was so enjoying FCPX after a year of premiere pro. Thought 10.0.9 had ironed out a lot of bugs, but glitches are the worst thing ever.

Wow - hours and hours spent... no solution...
OK, when I "expand audio + video" in the project timeine I get...
Then collapse that, and "expand audio components"
Wow! Dual mono. And the waveforms are clearly different, indicating true dual-mono. But I can't seem to independently move those tracks; all my tools just try to select parts of the clip.
If I click the clip and "open in timeline", it looks as above, but I no longer have the option to "expand audio components."
So for a different example, one that worked without any trouble or tricks...
Then right-click, open in timeline...
Very different result. That clip was shot AFTER the non-working one. The clip I shot before works as well. The odds that I changed something on my camera for that one clip, and then changed it back...??
I went through all my camera switches and menus (HMC-150, shooting AVCHD) and can't find anything remotely relevant to the problem at hand.
Also, as I said in my list of attempts at solving, a couple of other clips had the same problem and it went away with solutions 3 + 6 above. So it's definitely, in my mind, a program glitch.

Captured stereo convert into Dual Mono

Hi all,
Some of the footage I have to work with is captured as DV with stereo audio tracks.
That's not so nice, because the audio is actual 2 mono channels (2 different mics on interviews)
I know I can switch off the stereo pair in the timeline. But that's tedious. I need to alter everyclip everytime I drop it in the timeline. Also I cannot Unpair the clip in the viewer, while I do need that because I want to lower the level of only one channel during chosing the quotes (because of wind in 1 mic for instance).
So it would be nice to be able to alter the master clips in the browser from stereopair to dual mono.
But I canot figure out how. Can this be done in FCP?
Can this be done in Quicktime.
Any ideas.
thanks
Rienk
NB (I know how to set up dual mono in Log and Capture. It's just that 10 tapes, that someone else did capture in stereo, and I need to work with)

UODATE:
Just opened one of the good clips (captured as DUAL Mono) in Quicktime. Then I see 2 seperate soundtracks. Sondtrack 1 with one ch1 set to MONO and Soundtrack 2 with one ch1 also set to MONO. It that way it differs from the two channels in the one Soundtrack 1 in the clips that were captured as Stereo.
Export the original masterclip from FCP with Export using QT conversion. and set it to export 2 discrete channels will indeed create a file with 2 Mono cannels. And they import as such. "2 Mono" it says.
Reconnecting the master clip to the newly created Dual Mono clip let FCP still think this is a stereoclip (As Andy pointed out, this is indeed not working)
Reconnecting the sequence clips to the newly created Dual Mono clip seems to work. But when I do match frame, then there comes again a stereo-version of the clip in my viewer. (also of course this is because it is looking to the original masterclip that we cannot change in FCP, as we saw in the previous sentence).
So I found a way to create new Dual Mono masterclips, but still I'm not able to alter the originals to the sequence clips.
The building will close here. So have to leave.
But I will try if I can change the settings of the masterclips from within an XML...
OR the solution would be in QT to split the two channels in two soundtracks in Quicktime... But how?

Convert two mono tracks into one stereo?

I've imported a clip from my DV camera into Final Cut. For whatever reason, the clip audio is two mono tracks rather than one stereo track. Is there a way for me to convert this to a stereo track after the import?
Thanks very much,
Greg

Select both clips in the Timeline, then go to Modify->Stereo Pair (Option L). But if both clips contain the same audio information, it won't really be stereo ... just two tracks panned left & right.
If you want the audio to come in as stereo when you capture next time, make sure that you have the Capture settings for the audio set to "stereo."

Transcoding XDCAM from stereo to dual mono

I'm actually using Compressor at the moment, but am trying to convert HDV clips shot in stereo into XDCAM HD clips that will support write-back to my PDW-U1. But the U1 only supports "dual mono" audio, not stereo. I'm looking at the audio tab in my Compressor settings, and don't see such an option. I'm currently running tests, but has anyone found a way to create supported audio for write-back to XDCAM devices?
Chris.

Panning the audio to the center does not work for me. Once you choose Dual Mono, a single track will be either left or right depending on which track it's on. I worked around this by making a new sequence with "Dual Mono" as the audio output. I then dragged the original HDV sequence into that timeline and my single channel-1 audio channel now comes from both speakers. But it's not stereo. Its Dual Mono. I wrestled with this into the wee hours and this was the only work around I could find to output a show to XDCAM without the audio being messed up.
Somebody needs to seriously get to work on fixing this problem. Many broadcasters are now accepting XDCAM as a submission format. This is great, but it has some serious drawbacks as it sits right now.

(True) "Real" Stereo tracks converted to Mono after 5.1 update

Hello:
I have true stereo (as opposed to dual/centered mono) vocal and guitar tracks included in my most recent project. When I played everything back yesterday I noticed that all the "real" instruments had been converted to mono. I checked the source AIFF files and discovered they are still stereo. I typically record multiple vocal tracks and the export the resultant combined vocals (mono) and clean things up in Amadeus Pro. I often split the track, offset one channel, merge the channels and save the now-stereo file which gets imported back into GarageBand. This saves me from having literally hundreds of iso vocal tracks to deal with and it also opens up the vocals by spreading them across the stereo image.
The unwanted stereo to mono conversion has happened once or twice the past and I've never really figured out a remedy other than reimporting the AIFF files.
I was simply curious if anyone had experienced this phenomenon before and discovered a fix before I began the task of reimporting the stereo tracks. Btw, earlier versions of the project were unaffected by the update (if indeed it was the 5.1 update that cause the problem)—so it appears that only the current working project was altered.
Thanks!
~Huck

I discovered I had only one option (mono) until I unplugged my Mbox and selected System Setting as input source in GarageBand. At that point, stereo became available as a option and I went track by track enabling stereo playback. Thank you very much for your assistance! While I'm not entirely certain why having my Mbox selected as the input source changed all my "real" tracks to mono, at least I don't need to go through the hassle of re-importing the source material. I need to use the Mbox for guitar and bass tracks, so hopefully this was a one-time oddity.
Again, thank you for your help!

Dual Mono Audio Mysteriously Changes to Stereo When Match Framed - Why????

Hello everyone,
I am having a very unusual problem with the audio on my project, which I'm working on in FCP 5.1.2. All of the audio was captured as dual mono (channel 1 + channel 2), and yet when I match frame the audio clip from the sequence it shows up in the viewer as stereo, panned to -1. When I double-check the source clip in the bin, it is dual mono panned to 0, as it should be. Also, the clips mysteriously seem to pan -1 in the timeline occasionally, even on sections that were verified as being correct in timeline previously.
Does anyone have any idea why this is happening, and any solutions?
Thank you so much,
mynaah

mmmm this is an odd one... the only thing I can think of is that you are changing these clips once they're in the timeline. It's done with a keyboard shortcut: option+L... it will change a dual mono track to a stereo pair. You can change these files back though... typing opt+l toggles the condition back and forth.

Converting clips to dual mono

I'm trying to convert HDV clips shot in stereo into XDCAM HD clips that will support write-back to my Sony PDW-U1. But the U1 only supports "dual mono" audio, not stereo. I'm looking at the audio tab in my Compressor settings, and don't see such an option. I have Mono, Stereo, Stereo Headphones, and on and on. I'm currently running tests, but has anyone found a way to create supported audio for write-back to XDCAM devices that would be dual mono? Or is there a feature in FCP that I haven't found?
Chris.

This has to be done through Final Cut Pro. Not possible to do in Compressor yet.
Have a look at this article: http://www.larryjordan.biz/articles/ljmultaudio.html
"In Final Cut Pro 6 the Sequence Settings window got a new audio export option called Discrete. This option is used with the Export QuickTime Movie command. If you choose this option, each exported QuickTime audio track is labeled with the corresponding output bus number of your sequence."
http://manuals.info.apple.com/en/FinalCut_Pro_6_NewFeatures.pdf
Here is what I would try doing.
1. Make a sequence in FCP with dual mono audio and add your HDV material.
2. Choose File > Export > Using Compressor
3. Create a new QuickTime Movie setting with the XDCAM compressor you want (under video settings)
4. Set the audio to Pass-through
5. Select at destination and a name for your clip and hit submit!
If that does not work, change the sequence settings in FCP to the XDCAM preset you want, change the audio output settings, and add your HDV material. Render and output.

Convert Mono into Stereo

I am using an older lapel mic and it records in the mono format (I think). On playback I am only receiving sound out of the left speaker. How can I convert this, using Soundtrack Pro, either into a dual mono format or into stereo with the end goal of getting sound out of the left and right speaker?

I have several audiobook mp3 files which only have left channel sound -- makes the volume too low when I play the iPod through the car stereo when driving.
Is there a way to convert to stereo by just replicating the left channel?
Thanks!
Edit > Preferences > General > Import Settings, Choose "MP3 Encoder" and "Custom." When the "Custom" selections come up, set "Channels" to "Stereo."
Now, highlight the track in your iTunes library, and use the command "Advanced > Create MP3 Version." This should create a new version in stereo. It will leave the original in place, so you now have two. Make sure to use the newer one in the car.
I have not tried this but it should work.

How do I import stereo audio as pan centered, "Dual Mono?"

Greetings,
For most of my video recording, I’m running two wireless mics and am recording in stereo.
90% of the time, I’m working with one track or the other and, because I’m cutting for broadcast news, the pan for the audio needs to be centered.
Is there a way to import the audio I recorded in stereo as Dual Mono with the pan for each channel center?
It’s a pain to have to go through each clip and make it Dual Mono and then chose Pan Mod Default to center it.
I bring in my video as indiviaual clips so I can’t select a single clip in the Event Panel and make my changes for the whole project.
Regards,
Steve

Select the clips in the event, and set the audio as [Dual] Mono!
There is, as I remember, no option for this during import - but you can select multiple clips and set it on all at once.

Mono to stereo converter for 6600

Hey guys,
Does anyone have any clue how to convert music output from mono to stereo in the nokia 6600?
Thanks,
I need a reply soon plz!!!
Thanx

It is a physical impossibility. If there is only one line out signal, you can't convert it to two with any converter (software or hardware).
If you really must have stereo output, then you need a new phone.

Converted mono to stereo

I converted a left channel recording from imovie hd to both channels using quicktime. Now the audio track is way to long even though the size is the same. Format: Linear PCM Channels: Mono Rate: 48 (the rate decreases the size but it doesn't matter). Any ideas how to keep the audio the same length.

I can't reproduce the problem with "Save as..." again, so the tracks switched from mono to stereo somewhere between the time I recorded them and by the time I was done tweaking their EQ and compression settings. I don't know how to delete or edit my discussion question above, sorry!
