Sorry about the double post. Please replies to this thread.
I didn't know how to edit the previous to change IDE to API.

Pavillion 15 n097sa laptop. L and R audio coming through both speakers at same time.

   Hi, so basically, i have just upgraded to this 15 n097sa laptop (new to me) from my old aspire, and it is sooo much better.
    Only, I have just noticed that when either left or right sound is coming out of both speakers at once. i noticed it whils wearing headphones. the left definitely comes out of the left slightly more, and the right as well respectively, but they still come out of both speakers quite a lot.
     To make that clearer, the left only channel is coming through both speakers at once, instead of just the left speaker. And the same for the right channel.
   i have only done a real test on youtube stereo test videos, the same i tested on my old acer before, which came out of correct speakers.
i have a dts sound, whatever that is, and it could be down to simply changing the settings, but i don't think that's it.
    Does anyone else have or have had this issue too?
I know i am a pc simpleton, but please go steady on me, ta.

please, and thank you very much indeed, Sofa.

USB Audio Device only plays left channel out both speakers.

usually i use my Yamaha Audiogram 3 usb audio device to record things in cubase, and when the cubase settings are set it is fine, but as soon as i close cubase, the left channel of any audio (like itunes playback) plays out of both left and right speakers in the headphones i use. this only happens when the Audiogram 3 is plugged into 1 certain usb port (of 2).
its even fine when i have cubase running in the background while i play music from itunes. it just doesn't make any sense. it also appears to recognize that its stereo in one port, but not the other.
i would suspect it has something to do with the drivers for the usb device (if there even are any), that the drivers it placed into the system only applies to that one usb port, but if thats the case, you would think it would install new drivers for the other port as soon as i plug in my audiogram, but thats not the case.
no cd for the audiogram. you simply plug it in.
ive tried restarting the computer, plugging it in again, trying to change the settings. nothing seems to work. i need the other port to work.

Try resetting the PRAM. Info here:

You may also want to take a look at the Audio MIDI Setup utility and make sure everything is configured properly there.

Merged clips and modified audio channels bug/issue

My problem is that if I create a merged clip and modify it's audio channels Premiere (both CC and CC2014) does not respect the modification under specific circumstances. These circumstances are: if I use keyboard shortcuts or the source window buttons for overwrite/insert to cut the merged clip into a timeline. However, if I drag & drop the clip from the source window or from a bin into the timeline Premiere will respect the audio channels set through modify audio channels.
Here are steps needed to create my problem. You will need a video clip and an audio clip with at least two channels to reproduce this.
1. Create a merged clip from the video and audio. Does not matter if you have "Remove audio from AV clip" enabled or not.
2. Right click on the merged clip in the bin and select Modify -> Audio Channels.
3. Set the merged clip's audio channels to Number of Audio Tracks: 1, Channel Format: Mono. Set the source channel for Audio 1 to anything except Channel 1. Click OK.
4. Make sure you have the merged clip open in the source monitor. Use keyboard shortcuts (. or ,) or the insert/overwrite buttons in the source monitor to cut the clip into a sequence.
5. The merged clip in the sequence will use channel 1 for audio, even though it has been set to use another channel.
6. Now try drag & dropping the merged clip from either the source monitor or from a bin into the sequence. It will now use the audio channel that has been set through modify audio channels.
My workaround is to use drag & drop for now for affected clips, but in the long run this is a pain in the backside.
My question is if this is something that affects other users as well. And while I'm waiting for a fix, if anyone has any suggestions on how to get modified audio channels to work properly, I will gladly listen.
I have filed a bug report for this. I have reproduced this on multiple Windows 7 machines with Premiere Pro CC and on two Macs with both CC and CC 2014.
EDIT to add: I have been in discussion with Rameez from Adobe about this through the support chat and have been told that this is working as intended. He suggested I post a thread about it to see how other editors feel about the functionality. I personally feel that the way it works now makes no sense at all. If others feel the same way, maybe this issue can be fixed in a future update. So please make your voice heard.
EDIT to add: In most usage this might not be an issue at all. But if for example you have external audio on multiple channels and to make sure you have a clean timeline, you wish to remove extra tracks from your merged clips and those extra tracks happen to be any track before the last one(s), you will find that editing the merged clip in in any other way than drag & dropping it in the sequence will result in you losing those last tracks instead of any tracks in the middle that you have disable through modify audio channels. I would think that the audio channel modifications should work no matter what way you cut the merged clip in.

Going to try, but here is my workflow and have not encountered any problems until this last P/U days footage. I've been doing things this way because I found having all files in the project was causing it to crash constantly when I was working. I have a new I7' processor IMac with 24 gigs of RAM. And since Premiere does not allow you to have multiple projects open at the same time (Wish this would change. Avid and FCP both allowed multiple projects) I have to do things this way.
Pre-workflow Project File
Label all Video and Audio files to match Scene #'/Takes
Set in points on all video and audio to reflect slate
Merge Clips
Working Project File
Import only Merged Clips into Project. Either via import or copy/paste
Now I've done this workflow from just about the very beginning. Deleting all of the original source video and all audio clips from my working project so only my bins containing my merged clips remain. Have had no problems and edit has been smooth. Did a pickup day last week, followed same steps as I've done in the past, imported the merged clips into my working project and the clips have the audio set to none by default. Now once I go into the sequence I can manually set it and it's there but I cannot play audio in the source monitor which is how I edit, there's no reason I should have to go back to the crappy FCP way of editing doing the copy and paste from a sequence.

Enabling AirPlay to multiple speakers causes audio channels on local computer to playback incorrectly

iTunes has an audio bug that has been a problem for the last couple releases and it's been driving me crazy lately. The problem is streaming audio to any AirPlay devices from iTunes causes iTunes to for lack of a technical term "munge" the audio placing back out of the local audio output. It seems like stereo audio stops playing out of the local audio output and instead either the left or right audio channel plays back out of both speakers. The stereo channel audio playing out of the AirPlay device appears to be unaffected.
This can be reproduced by:
1. launch iTunes when AirPlay output device is available (AirPort Express, AppleTV)
2. open the Multiple Speakers panel
3. make sure both "Computer" and one other AirPlay output device are checked
4. playback an audio track you are familiar with that has clear stereo separated audio (something with a vocal track with one singer mostly on the left channel and another mostly on the right channel is a good option)
5. the playback will sound odd, like parts of the recording aren't present - vocals quiet or missing; guitar riff quiet or missing
6. uncheck all AirPlay output devices so that only "Computer" is selected
7. listen to the audio track again, it will sound normal
-- if you identify where the audio has missing elements you can click the AirPlay output device on and off in the Multiple Speakers panel and hear the elements magically appear / disappear
A great track to test with the The Beatles / Revolver / Taxman. From 1:12 - 1:25 there is a guitar solo. With the AirPlay device on this solo is completely missing and the track just has bass, drums, and rhythm guitar.
I'm not certain this has to do with stereo audio channel issues on the local playback, but obviously as soon as the AirPlay streaming code kicks it, something with the audio channels on iTunes is getting hosed. It's only been an issue for the last 6-9 months for me and audio streaming worked great for years before that.
Can others reproduce this problem? If so, Apple really needs to escalate this for a fix because using AirPlay pretty much ruins the quality of audio output currently which makes me never want to use it.

don't know if you are still looking at this thread, i hope so.
I have a similar problem, and I wondered if you might help. I have a macbook (2008) running the latest version of itunes (just updated) and Airplay tho with a pretty old router. (I got a relatively new one for the network just a few months ago but the one hooked up to my amplifier is an old airport-- the square ones-- I have had for years -- it's linked to the amp via the 3.5mm output jack)
I seem to run into this on the "Rubber Soul" album, and I checked it agsint the copies from iTunes and even ripping another edition of the CD. The vocal tracks seem to disappear, like the guys are singing at the bottom of a well. "Run For Your Life" for example, the verses Lennon sings are almost inaudible. On Norwegian Wood it sounds like they are in an echo chamber a mile away.
So, on all my other music it seems fine, but I wasn't sure if Steve Jobs hated "Rubber Soul" or what.
I haven't duplicated this on other music -- tho just now I noticed some weird effects on the opening track of Sgt. Pepper. Only half the vocals are on, the lyrics by Lennon are again near-absent) I might try to see what happens when I play the mono version of my Jefferson Airplane CD.
Is there a software fix? Should I be linking my airport in some other fashion to the amp? (The amp is pretty old, I got it in what, 1998?) Should I be using the USB link somehow to the audio out? Is thi an effect of weird stereo mixes of the 1960s?
BTW I am not trying to tream to multiple devices or anythign, just to the one.

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.
Splitting and Joining Stereo Tracks - Audacity Manual
I am not sure if this is close to what you seek
https://forums.creativecow.net/thread/3/883383
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).

Connecting audio channels with surround sound speakers

I have an art project coming up and I was wondering if anyone could help me. I have made a film with a separate .aif sound recording to go along with it. I want the sound to play from different speakers at different points, I have a surround sound system I was hoping to use and thought it might be possible to cut the sound files and somehow place them in different audio channels to link with different speakers. Would this work or is there another way to get the same effect?

I've not personally done it yet, but the theory is sound. I'd expect it to work just fine.
In any event, you'll know for sure once you try.

I am using duel thunderbolt displays with a MacBook Pro. I only have the option to have sound come from one or the other. Has anyone thought of making the left channel come from both speakers on the left Monitor and the same of the right? If yes, how is that done? The MacBook Pro could even be a center channel if configured in that order.

See the following thread on the same topic:

Convert a video with one audio channel (left) to both?

I have a home made DVD that for some reason only has sound in the left speaker. My audio system is fine. It's the DVD. Can iMovie (or other app) be used to route the left audio track into the right track as well so I have both audio channels working (obviously mono).
Thanks,
Steven

The problem is how to rip the DVD.
"Ripping" should not be required for a "homemade" DVD. The normal work flow here is to either copy the "main title" muxed audio and video files (VTS011.VOB thru VTS014.VOB) to your hard drive and then convert them to desired QT compatible audio and vide compression formats or use an application like HandBrake to convert the DVD directly to a more limited set of possible QT compatible compression options. (I prefer copying the files and using dedicated conversion software as it reduces the total combined disc access/conversion time requirements in most cases.
When I use QT Pro to look at these files, #3 is not viewable and, #1 only lasts about 30 secs of the intro, so I can't figure out where the content is hiding.
QT Pro is not required here. However, the QT MPEG-2 Playback component ($20) is required. Since you say you can see something, I must assume you already have this component installed. As to the ability to only see some "segments," the QT Player is very "fussy" about timecode breaks and will usually refuse to play succeeding content when they are encountered. Your best approach in such cases is to use a third-party, MPEG-based player engine that either ignores the timecode breaks (e.g., VLC) or has the ability to fix them (e.g., MPEG Streamclip).
Even the rip program HandBrake asks for individual files, so I'm held up even before being able to do what you suggest.
HandBrake does not "ask for individual files." It wants you to navigate to the VIDEO_TS folder since it needs to "see" all of the files to analyze the overall structure and generate specific menu options like title selections, chapter selections, alternate audio selections, etc. On the other hand, applications like iSquint, MPEG Streamclip, FFmpegX, Visual Hub, etc. use individual files or "sets" of files usually constituting a single title program.

Accessing both AUDIO CHANNELS

I only taped on one channel for a certain section of my footage. I cannot hear it in FCP even when I go to MODIFY and adjust the PAN settings. When I looked in the CAPTURE settings I see that only channel 2 was selected, NOT channel 1. If I captured this way does it mean that only channel 2 is captured?
What else can I do?
Thanks

Load the clip into the Viewer from the Browser. Is there only one audio channel? If so, it means that you only captured one channel (unless you've previously modified it somehow).
You can recapture the clip(s) completely, this time with both channels selected ... or you can just capture the remaining audio channel.

How Do I Add a Second Audio Channel To a QT Movie?

I just completed a project that originated in iMovie HD and was then exported as a full-quality QT movie. Problem is that I forgot that the source tape (VHS) only was recorded with audio on one channel. I would like to just clone the audio track from the right channel to the left so that after I burn it to DVD sound will be coming from both speakers. It was a mono recording to start with.
Any help appreciated!

I would like to just clone the audio track from the right channel to the left so that after I burn it to DVD sound will be coming from both speakers.
Don't bother. Open your movie in the QT Pro Player. Now open the "Movie Properties" window. Select the Sound Track in the upper half of the window and the "Audio Settings" tab in the lower half. A box will open showing the "channels" and their current "assignment." Click on the current "Right" or "Left" channel assignment and select "Mono." Now save your movie with its new channel assignment and you should be ready to go.

Premiere CC 2014 - exporting clip with separated audio channels (CRAZY)

Hi. I've been looking around the web and can't find the right answer.
It should be simple, but not!
I have my editing timeline, in which I have 3 tracks.
track 1 - voice over
track 2 - soundtrack
track 3 - sound effects
ALL OF THEM ARE 'Pan centered'...I here each one in both speakers, and they appear as stereo (2 wave forms in each track)
My client asked me to send him a XDCAM HD movie without mixing audio. Each track containing diferent sound, but (center balanced / pan)
When I export 4 channels, it works, but all channels have all tracks mixed!
is there any simple way to do that?
long time ago, in FCP was much easier
what am I missing?
I'm looking foward for an answer.
regards,
paulo.

In much the same way as FCP7 your sequence must be set to be multichannel (rather than stereo). Unfortunately, unlike FCP7, you can't make the change to an existing sequence - you must create a new 'multichannel' sequence (or change your default so they are multichannel by default) to be able to route, in the audio track mixer, to separate outputs.
I find it better to add some submix tracks to enable a master mix to be folded down to stereo outputs 1&2 as the 'downmix' in PPro is mono NOT stereo (unlike FCP7).
Both of these could do with being added as feature requests (ability to adjust number of outputs to existing sequence and mixdown to stereo, with level monitoring) at adobe.com/go/wish

Why does compressor settings of aac audio, stereo, create 2 channel mono from 2 discrete audio channel movies?

Why does compressor settings of aac audio, stereo, create 2 channel mono from 2 discrete audio channel movies?

well depending on how your audio is brought into your system you can select it as two streams of mono or a stereo pair. In reality, unless it's mixed in stereo, that's just two streams of mono locked together. Other streams brought in via other means, can have a lot more audio channels, e.g. 8, 16, 24.
In your case, with what you're doing, two separate channels works best, so you can control the levels of two very different audio sources. If, for instance, you were taking the feed from the mixing board during a concert, you might want their stereo out. Otherwise you might be dealing with the 1.2 zillion channels that they're mixing live.
I like separating the tracks coming in. I work with people who prefer to lock them together. Locking means the tracks move together during editing. Ok, fine, but I'm usually dealing with different audio sources, like you are: a camera mic (safety on location) and a close mic (shotgun, lav). Or I have a shotgun source and a lav. I want to determine the best source audio for the shot. Sometimes it's a lav, sometimes a different feed from somewhere else, sometimes the shotgun, and sometimes a mix of two sources. But if they're locked together and pre-set to come out evenly from both speakers there no way for me to make a determination. The other guys like to cut and figure out the audio later.
To each his or her own. . .

Premiere CS4 - how to duplicate left audio channel to right

I am editing old footage in which the audio signal is on the left channel only - the right channel is empty. I want to duplicate the left channel on the right so the sound comes out of both speakers. In Premiere 2.0 this was easy: right-click on a clip, choose audio options, then 'Duplicate left', and that was it. I can't figure out how to do the same thing in CS4.

One audio channel out (right) on iPad mini

I have only the right channel audio output on iPad mini headphone jack. Both speakers work. Same with music or video. Any help?

Try cleaning out the headphone jack with compressed air. If the problem continues try another set of ear buds. If the problem still persists, contact apple support for further troubleshooting. Hope it helps!
