Applying audio to both channels

Does anyone know how you can take a signal that is already inported into imovie that only has audio on the right channel and apply it to both audio channels?
Mac OS X (10.0.x)

iMovie does not allow editing of left and right channels BUT that's why it integrates with GarageBand! If you have the latest version of iLife, you can export the project to GarageBand for scoring and sound editing! This allows you to place sounds in the left or right tracks.
If you have QuickTime Pro, you can also do the same sort of thing, but I find it easier in GarageBand.

Mono Audio in Both Channels

I have audio AIFF files recorded in mono that when imported and put into the timeline only play in one channel (sometimes left and sometimes right apparently at random). It makes no difference how the pan is set for a given clip. How can I get these clips to output in both channels?

I bet you hear it on the left channel when the audioclip is on audio track 1, 3, 5, 7 or etc. And you hear it on the right channel when it is on track 2, 4, 6, or etc.
Go to User Preferences and check the Audio Outputs tab.
That's right, odd on one side and even on the other.
The Audio Outputs setting fixed it, but that preference only applies to new sequences. You have to set it for the current sequence in the Sequence menu.
Thanks.

Audio both channels??

I recorded some audio seperately on a zoom h4n. Now that I have it in FCPX, I can't get the audio on both channels. It only comes out the right channel. Is there a way to get it working on both? I have tried the Pan mode to stereo left/right but nothing seems to work.

ahhhhh.... once i double clicked on the synced video/audio file in the timeline it allowed to make the adjustment in the inspector window.
I switched the audio from stereo to dual mono. It appears to be working now on both channels. Thats weird how FCPX treats the synced audio / video files as a "compound clip".
thanks for the help.

Can I playback in both channels with my audio interface?

From what I've found so far I'm afraid the answer is already "no" but I have to ask for myself.
When I record into QuickTime movie (not Pro) using my Alesis IO|14 Firewire interface, it only plays back on the left channel.
Is there ANY way to get it to play back on both channels? (Or is this a sneaky way of urging us to upgrade to QT Pro?)
I'm assuming the audio quality of my M-Audio Nova condenser mic is better than my iMac's built-in mic, which is why I'd really like to do this. I don't even need true stereo, just both channels playing back.
(QT 10.1, on Lion)
Thanks.

The mic and interface record just fine into GarageBand, either as stereo or mono, and plays back out of both channels with the same setup, so I think the problem is with QT.
I don't find any kind of switch like that in the Hardware Direct Monitoring software for the Alesis, but I'll investigate further.
As I mentioned, I've searched this and other forums and it seems like this is just how QT is set up. But I was hoping for some sort of solution.
As previously indicated, I am not familiar with your IO device, so let me ask a few questions here.
1) Is the Nova mic you mentioned mono or stereo?
2) If mono, are you using two of them?
3) If mono and you are not using a pair of mics, does the input interface hardware have the ability to blend left and right (mic 1 and mic 2) input channels?
4) If mono, you are not using a pair of mics, and the device has no ability to blend left and right channels, are you you using an adapter cable to input a split signal to both input channels of the device?
If you are using a mono mic to input a signal to only one channel of the input device and are not/cannot blend this signal to both channels before output via the Firewire cable, then its sounds like your system is working normally and correctly. Basically, the Firewire audio is sent to the QT app as received from the Firewire device and recorded as is in stereo. I.e., if the left channel is active with the mic signal and the right channel is empty, then the audio is recorded only to the left channel and the right channel records the "nil" signal/nothing. On the other hand, GarageBand is an audio editor designed specifically to blend, pan, duck, filter, and/or otherwise taylor audio content as desired by the user. (I.e., which includes the ability to re-channel a single mono audio channel to both channels of a stereo track during the recording process which the QT app can't do.) In short, both apps are doing what they are designed to do as they were designed to do it. As such and as previously noted you have three basic options here.
1) You force the IO device to send stereo or two-channel mono audio to your Mac by using two separate mics, use a single stereo mic with dual channel audio output, using an adapter cable to split the single mono mic audio output line into two separate lines to be plugged into both channels of your IO device, or you can apply/blend the active channel to left and right Firewire output channels within the device if it has this capability.
2) You can use GarageBand to do create and export audio recordings instead of the QT app, or
3) You can purchase QT 7 Pro in order to fix your left channel problem post recording by simply applying the left channel audio to both left and right channels within the audio track so it will play as you want in any media player on your computer.
(Actually, there is a fourth option if you are using an external amplifier for playback, which is to simply use the output amplifier to accomplish re-channelization during playback rather than actually fixing the media file with QT 7 Pro.)

Mono audio input from lapel mic - how to create audio output in both channels?

I'm recording audio with mono lapel mic, i.e. only one channel.
I need output audio in the finished movie to play in both channels.
Can that be done in FCP X, and how.
Thanks a bunch.

Thanks, David.
So, if I have talent A on the left channel of the video, and talent B on the right channel of the same stereo recording...
can I pan each of these "mono" sides centered so they both come out the left and right sides ?

Duplicating audio to play in both channels

I want to take my audio for channel one and duplicate it so that the same audio plays out of both left and right channels. I can duplicate the audio and put it on the layer below but it just plays both layers our of the left channel. how can i make it play out of both left and right channels?
Thanks

It sounds like you originally had a stereo pair (a1/a2) that you unlinked, which gave you a Mono(a1) and a Mono(a2), and then you deleted one of them.
When you unlink a stereo pair, each resulting Mono track retains its original properties, including left or right channel assignment. This can be changed with the pan control in the Viewer.
When you duplicated the clip (a1 for sake of argument) and placed it on a new track, all you got was another copy that retained all the same characteristics of the original - including the left or right channel assignment. That's why you still only had audio from one channel.
The way to change this is to pan to center as I described above.

???_Missing audio on one channel in Prem.Elem. 4 & 7_???

Hello everyone,
I have a problem concerning Premiere Elements 7 and I can't find a solution to it. Maybe one of you had this before and is able to help me out.
I have a project with several clips where I removed the original audio and added a soundtrack file to play along. The problem is that there is only audio on one channel when I play the scene in preview. Balance is set correctly, audio file is all right. If I look at the audio file in the audio preview window both channels are visible and play just fine. If I look at the audio mixer and start the scene preview both channels are visible in the peak meter but I still only hear one channel. It doesn't matter if the audio is mp3 or wave. I looked at the audio preferences (audio output mapping): when I change the speaker setup, change right/left channel for the output devices the missing channel changes to the other side. It seems it is somehow connected to these settings. But it's the same settings as with other projects which work fine. So it's gotta be a project-related problem. It's not only in the preview missing but also when I export the scene to file. It is only with this project, but it's too much work to rebuild it. I tried the project with Premiere Elements 4, but it's the same. Other projects work fine.
I'm running it on Win XP+SP3, Intel 2,8 GHz, 2 GB RAM, Nvidia 6800 GT, MSI 865 PE with onboard C-Media 9739A sound chip, lots of HD space.
Any suggestions on how to solve this problem would be very much appreciated.
Thank you,
Chris.

Thank you both for your answers. The audio file is stereo with different waveforms for each channel; I just checked that in Adobe
Audition. I also checked the settings of the audio card but there's not much I can change. After these problems occured I updated the
audio card driver to the newest version available. The audio files comes from the video clip I use in the sequence originally. I severed it from the video to edit it in Audition and re-imported it since Premiere Elements hasn't that much sound editing tools. The audio file is fine. There's no channel volume effect applied to the file. As I said I can load it into another project and everything works fine. Gotta be something in this project.
Ok, ok I found it! I was playing with the audio tracks and I moved the audio file to the soundtrack track and it works! Putting it back in Audio tracks 1 or 2, one channel is missing. Very strange behavior. Or is there a way to mute one channel on a whole track since it happend to all audio files in Audio tracks 1 or 2?
Anyway, it's gone and that's great. Thank you for your help!
Chris.

Recording audio from a Channel Send

I've done this before, but I can't seem to do it again.
I am trying to record audio from one channel (which is using an audio instrument) to another channel (an audio channel) using an audio send. I am not having a problem setting up the send. I am able to hear the audio correctly and independently on both channels. The problem occurs when I try to record the audio, because there is no "record" button on the channel header for me to arm the track. The track is set up as a "record-enabled" track, but in the space where the other tracks have the record button, there is just a empty space on this tracks header. Does anyone know why this is happening? Any help would be greatly appreciated.
Thanks.

Well,
I seem to have found the problem. It appears that "audio tracks" will not allow you to arm them for recording unless there is a possible real audio input device connected to the computer. I plugged in my Snoball mic, allowed Logic to set it up as a device, and the record button magically appeared in the track header.
Hope this helps anyone else who is having a similar issue.

Speakers - both channels out of right speaker

Hi - I have a Macbook Pro, bought second hand so should have said at the time, but....
All the sound, both channels, comes out of the right speaker. When i go into the Audio MIDI set up app, and play with the channel testing for the built in output, when i do the white noise test on channel 1, it comes out of channel 2. Channel 2 then obviously comes out correctly. When the channel 1 test comes out of the right speaker, it's just not quite as strong and clear sounding as the right channel sound. Then if i've got music playing and i go to the sound preferences, when i use the balance slider left to right, when left, it's still playing out of the right speaker, just quieter.
When my headphone or external speakers are plugged in, it works just fine. Left and right are perfect and I can use the balance slider to move the sound left to right and it behaves accordingly.
I was on Mountain Lion and am now on Yosemite and it's made no different. It had Mountain Lion when i bought it.
Any ideas?
thx

No audio from second Channel using Webcam Capture with ASIO source

I am trialing elements version 10 as I am looking for a capture / recording / editing solution for making music videos. I want to be able to record from my webcam and also record two audio streams silmutaneously.
I am using a logitech webcam pro 9000 and a line6 Ux2 Audio recording Sound device. The UX2 is an ASIO compatible device that allows two streams to be recorded; in my case guitar and Microphone for voice. I am able to do this in ASIO comaptible audio editing software.
So I have tried selecting the Audio device settings prior to starting a capture but each time I start a capture the audio device reverts to standard windows Realtek audio device. I then select the Line6 Device in the capture window and procede to record but I only get video and one audio channel. Is there a way to record live from webcam AND get both audio channels using ASIO driver?
Cheers
Greg

Only if your camcorder records in stereo. Otherwise, you will only get one channel of audio and you will need to use the Fill Left or Fill Right audio effect to spread the audio across both.

Stereo audio in left channel only.

Hi,
I have a strange problem with one of my projects.
I have created a large number of "talking head" videos/projects. I export them to FLV using one of PREs default settings. For just one of these projects I get audio in the left channel only. All other clips are OK.
When I play the clips on the timeline the audio is perfect in both channels. So somewhere in the rendering/output process I loose the right channel.
What am I missing here?
Thanks in advance.

Hi and thanks for all input.
Yes I use a mono mic, but the camera puts the sound on both channels.
When I play the timeline I hear the voice in both channels.
The timeline audio track shows waveforms on both channels.
Here is a pic of the timeline:
The project is corrupt somehow. I just tried creating a new project with the same video files and made a short flv out of it and it comes out OK.
I will try to redo this one which leads me to another question which I will post in another thread if not already answered.
Thanks for your input.

Stereo track is only showing audio in left channel in multitrack view

I have an echo Layla 3g soundcard. Whenever I place a mic into the front input and try to record into AA, I can get a stereo recording BUT with audio only on the left channel. However, if I record using the edit view, I can get both channels (L and R) recordings ok (this is from the same mic input from the echo layla. I have selected the correct drivers in the audio hardware set up. Anybody else having this same problem?
Quad core
Windows 7
4 gig RAM

With both Edit and Multitrack views, you get options to select what's going to happen in terms of recording behaviour, and they don't have to be set the same way.
With any input, you get options that typically say [01S] (stereo) or [01M] (mono). In Multitrack view,if you select a stereo input, but only plug a mic into one input, then any recording you make will only be on the channel that the input is connected to, and not the other one. If you select a mono input, then all you will do is patch that particular input to a mono recorded channel if you record in mono.
In Edit view it's slightly different. If you select a mono input, but then elect to make a stereo recording, that mono input will be patched across both mono channels.
If you only have one microphone to plug in, there's absolutely no point in making stereo, or dual mono recordings anyway. All you are doing is doubling up on the same information.

Xfi recording on both channel

Creative XFI I also have a M- audio Pre-amp.. When I first hooked it up with the preamp I was able to hear my vocals on both channels then I accidently changed a setting and everything went to one channel for Vocals..How do I get it back so I can hear my vocals on Both Channels..Also, I'm really having a hard time with that audio creation mixing board.. I have also tried to download the manual at work from your site and it doesnot preview sections of the manual when i try to view it.. I was wondering of you could assist me.. I hope to hear from the forum soon...

HUGE audio problem - Right channel only?

Editing i hear both channels or atleast 1 channel split. Regardless, after i export all of my clips except some sound loops/musc is on the right channel... What happened?
Had a video where only some clips(coincidently from a certain camera) were all right channel where as all other clips where both channels.
Confused. Give me some help over here.
Thanks

You got it!
That solved evrything.
Now my next audio thing is that my footage will come in one one side(left channel) so i have to put it from stereo to dual mono. However that is due to a setting of recording on my cam im sure.

I have video clips with 4 channels of audio, I can only hear audio recorded on channel one, how do I hear the other channels......?

I have video clips with 4 channels of audio, I can only hear audio recorded on channel one, how do I hear the other channels......?

What version of Premiere Elements and on what computer operating system?     Elements 13 on Windows 7
What is the brand/model/settings of the camera that recorded these videos?        ony PMW 320
When you import them into your Premiere Elements project, what does Premiere Elements Properties for that import give for
the audio description in the way of number of channels? If you open the Audio Meter (Window Menu/Audio Meters) and you play back
the video in the Premiere Elements Editor, how many channels does the Audio Meter display?
I just drag and drop video and when playing back only channel 1 will appear
What is your intended export for this video in terms of audio as well as video compression and formats?    MP4
I think you can only use audio if it's recorded on channel 1 or it does not recognize it.
Thanks for the help if possible,Kevin416 873 8374
