Static in Left Channel of Master (no clipping)

I have recently begun to experience static in the Left Channel of GB's master output. I am not clipping (nor am I close). I have been using DLSMusicDevice to play various general midi instruments and I get a sort of revereberating echo out of the left channel only when I play the midi instruments back. Audio that I've recorded via a MOTU Ultralite does not produce this problem. I have tried switching between a large and small playback buffer as well as toggled echo and reverb on the master track. Any ideas on how I could get rid of this?

Have you checked the volume and balance sliders in
the output sections of "Sound" System Preference and
Audio MIDI Setup Utility (Utilities folder)?
Thanks. The balance slider was skewed way right. (Volume took care of itself on a later restart).
Before I mark this as solved, can anyone tell me why the software would have decided to set the balance all the way to the right on its own? One minute it was working, I mute it to take a phone call, and then when I turn it back on only the right speaker was running.

CC 2014: all mono clips on left channel only

After updating Premiere Pro today (CC 2014) every mono audio clip is interpreted as stereo, with the right channel switched off – so every mono signal plays only on the left channel (panning o,o). When I select the mono clips and go to "Audio Channels", there is a second "Source Channel", switched to "None". If I switch this second channel to "Channel 1" (right), the problem is solved, but I'd had to do this for every mono clip in my project!
I checked the mono clips, and they show up with "Mono" in the meta data, and the source monitor shows a mono waveform, so that's not the problem.
Stereo files are playing stereo, no issues so far.
What's going on here?

Another good method that does the same trick without a filter is... After importing your file and before dropping it down on your timeline, right click on the clip go to Modify>Audio Channels. Select mono 2 channels and it does the same thing as the filter would. I use both methods a lot because of the way I shoot with a PWM Ex3. Have a good day man!

Route audio left channel to mono master

Our videographer records all audio to the left channel only, which leaves the right channel empty. Is there any way to route only the left channel to both the left and right master, or to route only the left channel to a mono output?

Premiere Elements 13 (not Pro), recorded a video with mono mic input (left channel only), need to create 2-channel (left and right) audio track for finished product. Help?

The question says it all. I have been all over the tutorials as well as the menus inside Premiere 13 and cannot find how to edit the audio track beyond basic balance, volume, etc.
I can see the Audio 1 track, shows audio in left channel only, but it will not respond to attempts to select, cut/copy, paste, etc.
Basically I just want to turn one-channel audio into two-channel audio.

Sure you do not want to give the Fill Left and Fill Right another try?
According to the Adobe document Adobe Premiere Elements Help | Effects reference
Fill Left, Fill Right
The Fill Left effect duplicates the left channel information of the audio clip and places it in the right channel, discarding the original clip’s right channel information. The Fill Right effect duplicates the right channel information and places it in the left channel, discarding the existing left channel information. For example, you might use this effect on footage shot with a monaural microphone plugged into only one channel of a camcorder, extending the voice of a speaker from one channel to both.
From what you wrote, your Premiere Pro video seems to be saying the same.
If that Premiere Elements Fill Left or Fill Right is no go, you might want to explore what you can do in this regard using the free audio editor Audacity.
Audacity: Free Audio Editor and Recorder
And, then import the Audacity edited audio back into Premiere Elements project as source media.
Is the speaker system OK?
We will be watching for your results.

Audio Left Channel is absent in app-specific instance

Hi, All:
I was just advised that this topic belongs here in the MSDN forums, so moved the topic from the Community. I am not sure that this particular forum is the correct one. If not, please advise where to put this question.
Here is my original question:
I have created an application (in Delphi) which uses audio output, but recently discovered that the left channel is missing. There is nothing in my program that would do this.
To further test this application, I did the following:
1. Used the Windows PlaySound command to output a simple WAV file. I moved this line to the top most part of the program before anything else was created or intialized.
2. This wav plays immediately on launching the program, but as with the rest of the program (which using SAPI, text2speech), the left audio channel is absent.
3. If I move the program (profviewer.exe) to another location than where the application is installed, the left channel returns.
4. If I change the name of the program to e.g. "test.exe" the left channel returns.
5. On my Win7 systems, if I changed the name from "profviewer.exe" to "test.exe" then ran the application to the initial password dialog then cancelled, then rechanged the name from "test.exe" back to "profviewer.exe"
I discovered that this audio channel anomaly was corrected.
6. On my Win8.1 system, changing the name of the app as in #5 did not fix the audio channel problem.
My guess is that there is some application specific registry setting that controls this. Could you tell me where to look for this so I can fix those systems with Win8.1? Or failing that is there some other work around that I could apply to get the
left channel audio back?
Thank you,
Chuck Belanger

Hi, Matthew:
Here is the output of Meters.exe from a user with Win8.1 and who has no left audio channel in the program (Profviewer.exe). Hope this helps to fix this head scratching issue.

If I have audio coming from left channel. How do I make same audio Left and Right?

Hi there,
I've recorded some footage with a mono mic and it recorded the audio on the left channel of the audio. In FCP. I placed this audio clip as a part of a multi-cam clip but the sound is only coming out the left. Is there a way to set this audio to mono or to make them play the same levels through the left and right channels?
Thanks,
Caleb

Wow! 30 Seconds later, I figured it out. LOL
Under Inspector for audio, you just click on channel configuration, click on channel and use "Dual Mono" mode. Thanks Caleb!

Help I only get a mono audio in the left channel now

I am only getting a left channel mono sound when rendering
My videos with iMovie on my iPod Touch 4g 32 gb.
My first iMovie came out fine with multiple clips and all in stereo
I can find no help on the issue.

They are either linked and/or a stereo pair. If you see the name of the clip underlined they are linked...press "Command + L". The undeline should go away. If you see arrows on the clips pointing to one another then that is a stereo pair. Press "Option + L" and the triangles should go away. You can then use "Command + L" to relink you video with your audio...if you so choose.

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.

Only the Front Left channel of my USB mic is being recognized!

The microphone in question is this. When I plug it into my Macbook and look at it through Audio MIDI Setup, I can only see the Master channel and 1: Front Left. The Front Left channel was also greyed out, with the slider down at 0. When I record through the mic in Premiere, I (expectedly) get audio from only one channel. Could someone provide some insight?

I hopped over to Windows 7 in boot camp and plugged in the mic. In Sound Options > Properties, it's also telling me that my microphone is only one channel. Did I purchase a mono microphone? Is it that all microphones of this nature record to mono? Or is mine somehow faulty? It would make sense that this microphone would be mono, but the fact that the one channel is named "Front Left" in the Audio Midi Setup might have sewn the seed of doubt that something was off.

CAPTURE AUDIO MIXES LEFT CHANNEL TO MONO

Everytime I capture now, or batch, or capture a single logged clip, the stereo audio comes in as mono, using only the left channel. The right channel audio is lost.
I searched the postings, and found this was happening with a lot of people, not just FCP 5.1 HD, but with FCE, too. No resolution or fix as far as I could see.
Anyone know how to correct this major bug? I really need stereo audio!
Thanks,
Norris

After a lot of research, and NO help from calling Apple tech support, I finally determined this (which has to do with HD/1080i/60 only -- I am not sure about NTSC settings):
In the Clip Settings tab, in "Log and Capture" (in HD) there is a little box next to the simulated VU audio levels meters. Click that box. It should toggle on/off two little lines that combine audio channel 1 and audio channel 2. When the little lines are there, that is STEREO. WHen they are not, in my FCP 5, it mixes both tracks to mono from channel 2 (Left).
As for your other question -- yes, you can manually go into the logs and change the settings, and then recapture.
a pain this is, huh? And no written mention of it in any manual.
NOW - as for previewing the audio while logging and capturing? I still cannot do that and have been waiting two (2) weeks for a reply from an Apple tech support guy who was supposed to be researching this for me.

Stereo audio plays back left channel only - premiere pro CC2014

Dear All,
I recently upgraded to premiere pro CC and find that (just like sometimes in CS6) when i place an audio track (or clip with audio) to the timeline it plays back LEFT channel only. When I move the same clip to another (existing or newly created) sequence it becomes two channel stereo and plays back OK.
The question is, since i created sequences with the very same audio settings, what might cause this issue.
(fill right with left channel does not work because it IS a stereo track i suspect sg is wrong with my sequence settings- but i cannot figure out what exactly.)
I hope it's not a bug and it is just me doing sg wrong. all input is highly appreciated! THX in advance!
Misi

I know i just happened to be mid-project when trial period ended...
Still looking for the why's though, since I asked around and there ARE some people who expőerience similar issues!
Thanks in advance (Ann, too)

Sound only on left channel

Hi,
I'm shooting some video on a JVC GR-DV3 (admittedly old but still does the job!) and am using an Audio Technica ATR 3350, omnidirectional Lavalier condenser microphone as the motors are too noisy for speech using the built-in mics.
When I import the clips into iMovie all the sound is on the left channel, not equally distributed between the two?
Any thoughts or fixes?
JC

I bet the microphone is a mono microphone. When you plug that into a 3.5mm stereo microphone input, all sound is "sent" to the left channel. You need an adapter cable or adapter socket.

Panning hard right still leaves bleed in left channel

I'm using a drum kit garageband instrument to trigger a click (a shaker sound). I want to route it to the right output only, so I can send the right channel to the musicians and the left channel (with the other instruments in the arrangement) to the front-of-house in a live situation.
When I pan the shaker hard right, I still get bleed in the left channel. I've tried different sounds, bussing to an aux and making that aux mono, then panning it right, etc. Nothing seems to be working. I want the shaker to ONLY come out of the right channel. None at all in the left channel.
Any ideas what the problem is?
Thanks!

Coincidentally, that is what is in Apple's pre-made channel strips for mastering on the master fader. I wonder why they would do something like that?
I think a lot of channel strip presets may have questionable parameters. They may sound good for some things, but certainly not for everything. As with most factory presets, check 'em out for ideas and inspiration, but don't rely on them.

Keynote Audio only left channel

Has anyone else had this problem and how did you solve it? I am using an M Audio Fastback USB input to record to Keynote and the audio is only recording to the left channel/speaker. Can someone tell me what I am doing wrong or how to fix this?
Thanks,
Paul

System Properties > Sound
in the output tab, select Fast Track USBand centre the Balance slider
in the input tab, select Fast Track USB and move the volume slider to the far right
Applications > Utilities > Audio MIDI setup > M-Audio > Input; set the master to the far right
The front panel controls affect analogue phono out connectors and the headphone jacks for monitoring, they do not control recording.

Exports only left channel

When I replay the video within PrE 10, the sound is stereo. However, when I export it (tried several format, ie WMF HD ) it will only play sound in one of the channels.
Doees anybody know, what could be the problem here?
Best regards,
Peter

I've just been experimenting with this for a couple of hours. It seems to be something in the settings for the project. I've tried to import exactly the same media (footage) to a new .prel file, I made from scratch and here sound works perfect. I've also tried to delete all the clips in the timeline for the problematic .prel file, imported new media and placed them in the timeline. This again gives only sound through the left channel after exporting.
The thing is that I've made a bunch of .prel files for a project where we need to make a lot of short videos. They are all based on the same template file (I made one .prel file that contained all the footage I needed, so I didn't have to go through the import process for each video, I made). Therefore starting all over again will really be a pain. I guess that it is a setting or something which I've made wrong in the "template" file and which has thus been replicated to all the other files. The strange thing is that the balance is perfect when reviewing the video inside PrE, only after exporting it, no sounds comes in the right channel.
I simply can't understand what I do differently in the new files and what I did in the old template (and thus in all the other files I've made). They have the same project setting, as far as I can see.
Bill, I haven't been able to find out if it has keyframes. It sounds quite possible that this is what I've done without knowing it, but on the other hand, it's strange that it changes this many times during a couple of minutes. And after investigating I found that not all the videos have this behaviour, but all of them gives only the sound through the left channel after exporting. So probably the two problems are not interrelated.
I really appreciate your help. Thanks a lot.
