Duplicate audio channel

I recently recorded a wedding with my DV camcorder. I used a lapel microphone as the audio (connected to my camcorder's mic input jack). Unfortunately, this audio is only heard from the left speaker. I would like it to be heard from both left and right.
I have at my disposal various versions of iMovie, but am willing to use whatever A/V editing software (prefer inexpensive solutions) to be able to duplicate the audio into the right channel.
Any recommendations?

FCP supports both Mono and Stereo Pair tracks. If you have a single (mono) track, why do you need to duplicate the channel? Two channels of the same material is still mono (even if you pan one to the left and the other to the right.)
Why not simply pan the one track to center and be done?

Merging clips results in several duplicate audio channels/tracks

I am trying to sync my audio and video in Premiere, and something is screwing it up.
I have my video track, that has 2 audio tracks.
Then I have my polyphonic wav file, that has 5 audio tracks.
2+5 = 7, right?
So why is it, when I merge my two clips together, that Premiere decides to create 20 additional tracks for my Merged Clip, totaling 27 tracks?! The majority of them are blank/empty/silent. Why is it doing this?
ORIGINAL FILES SYNCED UP
AFTER - MERGED CLIP ON RIGHT

I don't understand this part of your explanation. It's been a while since I've used PE, since FCPX's sync and multicam features work so well.
Why not try a short test – skipping the PE steps entirely. Select two of your clips and let FCP automatically create a test multiclip matching the HVX waveforms with those on the 5D. Open in the Angle Editor – or start a test project and see whether the boom mic track is present.

Duplicate one channel of audio FCPX

Im editing a wedding were a videographer used a wireless mic on the groom, How do i duplicate that wireless audio channel so i can hear it in both speakers? FCPX vs 10.0.9. thank you

What are you seeing in the meters? What is the channel configuration, stereo or dual mono? Dual mono should let you switch off the unused channel and send the audio to both sides.

Audio Channels in Timeline

Can I break out audio channels, or eliminate a R channel once I've dropped it into the timeline? I have separate mics on L and R channels, and want to just choose the L channel mic. But I failed to set channels on all clips before moving into the timeline.

You'll get different suggestions/methods, but what I use is the FILL LEFT and FILL RIGHT audio effects. If you want just the mic on the left channel of a stereo clip, add FILL LEFT and then you will only get the left channel audio, on BOTH the L and R channels.
To expand on that, you could copy/paste to duplicate the clip, and add LEFT to one clip and RIGHT to the other, and then mix them as if they were seperate channels to start with. Or, add razor cuts to single audio clip at points where you want to switch mics L or R, then alternately apply the effect as needed to each segment and add audio crossfade at cuts. Many ways to work with it.

Stupidly only recorded onto one audio channel when filming.

I stupidly only recorded to one audio channel when filming. Is there any way to get imovie to duplicate the recorded track onto the other channel?

I think if you open your video in Quicktime Pro you will be able to save as mono audio with both channels the same.

Hearing only one audio channel in source window & in timeline

Hi all,
As most of you I get a lot of footage where the audio is split - left channel for gun-mic\\front-mic and right channel for neck mic.
A lot of times I want to preview only one audio channel in the source window.
I cant find a way to do it.
Also whan I try to hear\monitor only one channel when the clip is in the timeline - its a problem -
the only way I know is by using the fill Left\Fill right effect - it is good when I do the final mix
but sometimes I just want to hear one of the channels.
without the tidius way of adding an effect just to preview something and then deleting it.
I'm sure there a way to do this - right?
thanks!

Thank you very much for replying
Select the clip in the Project Window and duplicate.
Select duplicated clip > clip > Audio Options > Source Channel Mapping.
Disable one of the channel and hit OK
Place this clip on the timeline and ALT + double click so it will open in the Source Monitor.
This is a very messy and unconfterble way to work - because I need to toggle this every time I want to switch channels to monitor.
Instead of adding the effect fill left/right you can toggle the effect on and off for the whole track in the Audio mixer.
This is a nice solution when I work on the timeline - but it won't help when I go on the source footage.
I think the only way to switch channels for a quick preview in premiere is by buying a Sound card with a channel switcher - or using a mixer...
so dissapointing...

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.

Get 4 audio channels out through SDI whit BlackMagic UltraStudio Express

Hi,
We have some issues with the Blackmagic UltraStudio Express and Premiere Pro.
We need to get out 4 audio channels through SDI for different broadcast and news feeds. We can't do that with the UltraStudio Express on different Mac Book Pro (one on OS 10.9 and one on 10.8.5) with Premiere pro CC and Premiere pro CS6. (We have try with the driver 9.9.3 and 9.6.8). The only thing we manage to monitor out of the UltraStudio is 2 audio channels.
We know it "could" work as :
- We are able with the same setup to get 4 audio channels via FCP 7.0
- We are able with a Mac Pro OS10.8.5 + Blackmagic Decklink HD Extreme 2 (driver 9.6.8) to get 4 audio channels with Adobe Premiere CC
Do you have maybe a solution for this ?
Have a nice day !
Best regards

My ipod's music quality is inferior. It doesnt have the surround sound/ left and right audio channel unlike my brothers ipod? is there a problem with the chip?

I have an ipod touch 4g (8GB), I got this about 2.5 months ago, the same time my brother get his. My problem is that I noticed that audio quality is better on his device than mine. I have been listening to music and had different music devices before (non-Apple product and mobile phone) and the quality of music is better when I used to listen to those devices as well as my brother's ipod touch. Im referring to the left and right audio channels. Im not so good about the technical stuff but the best explanation I can give you is in a music or a movie, there's an effect wherein you can here a sound only at the left ear phone/speaker that you cant hear at the right earphone/speaker. I mean for example in a song, a guitar intro can be heared only at the left
ear while the background music plays on the other ear. Or when theres and echo effect on the song that alternates sound on the left and right ear. I hope youre getting what Im trying to say. Im bothered that my ipod is fake or has an internal problem on the chips or something because I didnt bought this at an Apple Center/Mac Center. I bought it on a retailer. I am not able to visit any store or Genius Bar or contact an apple specialist through phone because of my work schedule and work load. I have contacted the retailer before when I tried to return it for replacement or repair but he told me that it is under Apple's warranty, not theirs. I do hope that I can get a help from you because I want to really enjoy my device. Thank you and Im looking forward for the responce/assistance form you.

I suggest you don't apply pressure to the screen - it's a Touch - you touch the screen not push it.

How do I export from FCP to a QuickTime file with multiple audio channels?

I'm delivering a project where the first step is to generate an HD Cam SR master, which I will be doing at a post-production lab. They will then do a QC check for me. To generate this HD Cam SR master, they need to me to bring in my 98-minute long movie on a firewire hard drive, in five equal parts -- QuickTime files. From these five QT files, the lab will then be creating an HD Cam SR master that will have...
dialogue on tracks 1 and 2
effects on tracks 3 and 4
music on tracks 5 and 6
MY QUESTION
a) I don't see any way to separate these audio tracks accordingly in the FCP menu for QuickTime export. Does anyone have any experience doing this?
b) And does anyone know the most efficient way to combine timeline audio tracks for this purpose? I have my dialogue sitting on the first FOUR audio tracks, actually. To deliver this film, I'll need to crush these four audio tracks to two, as listed above. I could generate an AIFF file, I suppose, import it back onto the timeline, sync it up, and then re-export along with the visuals to make the final QT file, but this seems like a generation loss.
thanks,
Shanked
PS the movie is made up of footage from a Sony PMW EX1. I used the codec "XDCAM 1080 24p 35mbs VBR" for editing in FCP. I'll either export to QT using this same codec or switch to "Apple ProRes" if my machine can somehow maintain the sync.

The following will answer both your questions a) and b).
Click on your master timeline and press cmd+0 (zero) to bring up Sequence Settings, then click on the Audio Outputs tab on the right. Click on the Outputs option and change it to 6. You can leave them as Stereo pairs.
Now, back on your timeline, you need to make sure all your audio is organised so each track. A1, A2, A3, A4 etc has all the relevant media on it.
Then, on the left of the timeline you see the Destination toggle buttons, then you see the Padlocks to lock tracks, then you have the Toggle Auto Select squares. If you right-click on the Toggle Auto Select squares you bring up a little sub-menu, at the top of this list you'll see Audio Outputs, which will show the stereo channels for that particular track. As you've changed the number of Audio Outputs in the Sequence Settings, the list will show: 1&2, 3&4, 5&6. You just tick whichever channels you want.
In your case, you have dialogue on the first 4 tracks, no problem, just go down through tracks 1,2,3 and 4 as described above and assign these to Audio Outputs 1&2.
Then just go down through your music and effects audio tracks and assign them accordingly.
Now, when you export your timeline as a self-contained media file, it will have different audio channels.
I hope that makes sense. When you change the number of audio outputs as described in the first step, I believe the rest of it is fairly self explanatory, once you know where the settings are.

Help using multiple audio channels for one video

Hi,
I have a video file with 3 audio files (stereo (.wav), 5.1 surround (.AC3), and commentary (.wav).
I have placed these on the time line of the video track, but now I need to have buttons to target each of them from a menu. However, when is choose a buttons target, is doesn't give me the option of which audio channel to play (A1/A2/A3 etc).
Is this possible with just one track, or do I need 3 (each with a different audio file as A1)?
Hope you can help! cheers.
Tim

There is a tutorial on setting this up here;
http://www.kenstone.net/fcphomepage/dvd_languagenattress.html
BTW I would very strongly suggest to compress your WAV files to stereo AC3 files. It will reduce your overall bandwidth, and you will have a disc that will less problems in playing.

Feature Request: Modify Audio Channels from the Timeline in Premiere CC.1

Why have we never been able to modify audio channels once a clip is added to a sequence? I'm guessing there's a good reason Adobe has never had this feature. The lack of this feature is explicitly mentioned a few times in the audio section of the Premiere Pro CC manual, as if it's a benefit NOT to have it. But the benefit is entirely lost on me.
In my workflow, I synchronize my double-system video and audio before anything else. I do this in PluralEyes (and unfortunately I'll have to keep doing it this way, until PPr's sync on sound feature gets fixed—for me it's never worked).
Once PluralEyes has synched hours of footage and audio and placed it on a PLURALEYES GENERATED sequence, I import that sequence into Premiere. Note: Since I haven't gone through the step of creating a blank New Sequence, I don't get the opportunity to setup my audio channels the way I'd like in my sequence (i.e. Stereo recordings should occupy ONE track, not two. Typically these tracks come from a camcorder and are used for reference sound, or ambient noise at best, so I don't need them taking up precious real estate in my sequence).
Since PluralEyes doesn't merge my clips for me (or rather I don't want it to since I'm usually doing multi-cam sequences where I want to keep all 14, or so, tracks of audio), I have to go through the clips one by one and do a Merge Clip action once I've adjusted any minor sync issues, or determined which tracks I actually want to keep. But, and here's the key, at this stage I'm not yet 100% certain whether I'll use the nat sound or the wireless mic sound (separate audio recorder, etc). Furthermore, I don't really want to think about that at this point. After I've spent a few mind-numbing hours just ingesting files, sync and merges, I want to jump into the edit as soon as possible, before I lose all will to finish this edit. If I modify my audio channels right now, I'll lose the ability to make some creative decisions later on.
I'd like to start whacking out an assembly edit. And then after I have a rough program, I can start looking at which audio tracks (nat or double-system) I like better in each circumstance. This is where I become stumped that at this stage, I'm locked into whatever audio channels I've setup (or not) in the earliest stage of the edit, back before any media was actually on the timeline! It's at this stage, and usually only at this stage that I want to start Modifying Channels—FROM THE TIMELINE!
Does anyone else feel the same? If not, what is your workflow?
Feature Summary: Right-click on any clip, (master clip, sub-clip, merged, nested or otherwise) in the timeline and choose Modify > Audio Channels.
I've submitted a feature request, with a link back to this discussion, so please pipe in—especially if you want this feature.

Maybe its your specific workflow, asset mangement and use of a 3rd party application that runs you into an issue.
Take Pluraleyes out of the equation, I would imagine my workflow is the same as most everyone else. Find footage in the Media Browser. Import it. Create a Sequence and start editing. Use the Source Monitor to set Ins and Outs and then Insert the clip on the timeline.
At this point, if the audio needs to be modified, it cannot be done on the Timeline. The workaround, of course, is to Find Clip in Project; Modify Audio in the Project panel; then do a Matchframe to replace the audio clip. This works, but requires many steps per clip. Also, Matchframe in Premiere Pro CC is not reliable.
Introducing a new Modify Audio (from Timeline) feature as seen in the fantasy screenshot above would solve it.
I dont use Pluraleyse ...which I understand to be a synching aid...so I dont know the workflow it imposes on one .
Returning to Pluraleyes workflow, this issue is compounded by the need to Modify almost ALL audio. Every stereo track is separated and placed on two MONO tracks taking up precious real estate. This is not something Pluraleyes imposes. It is due to the way Premiere imports XML timelines. This would apply to sequences imported from Final Cut as well.
In this case it would be ideal to select both the LEFT and RIGHT mono tracks and choose "Modify > Audio Channels > Merge L/R Mono to a Single Stereo track." Ideal? No. I guess Ideal would be if Premiere would interpret XML files properly in the first place.
What actually is the issue with Premieres synch and merge workflow in your case?
Audio Sync in Premiere Pro doesn't work. Period.

How do I reduce the number of audio channels in the source or export settings?

I'. trying to export my finished edit through the "movie" setting but keep getting the message that the number of audio channels to create in the exported file must be equal to, or less than the number of channels in the source. Reduce the number of audio channels in the source. Reduce the number of audio channels in the export settings. I am at a loss as to what this means and how I proceed with it prior to putting it to DVD. Please advise.

What is your source, sequence settings and export setting. Which version of PP?
Prefebly a screendump of the export settings box.

Actually i have a long video clip and i have scatterred this clip into 6 diffrent portions
where i am not able to import the last video clip.It is giving me same error "file contain too many audio channels"".

Manoj

I too am getting this error in Premiere CS5. I was digitizing a Broadcast VHS and since I did not have a breakout box, I hooked it up to a Sony DV deck so I could connect via firewire and capture inside Premiere. I was able to capture and import 1 of the 3 clips and it did have 4 audio channels attached to it. However, upon closer inspection only 2 channels had a waveform. I captured the other 2 clips the same way, but this time, Premiere give the error "The file contains too many audio channels."
Any ideas?

I do not see a way to separate audio channels to edit them separately in Premiere Elements (any version).
Premiere Elements does have audio effects including Balance, Fill Right/Fill Left, and Swap channels, but that is not what you are seeking.
I would refer you to an audio editor such as the free Audacity for what you want to do.

I am not sure if this is close to what you seek

But, the opportunity seems to be in Premiere Pro, not Premiere Elements
Please review and consider and then let me your thinking on the matter relating to your Premiere Elements 12 (what operating system).
