Audio Center Channel gone

Hi there!
I have been trying to work this problem out for some time without success, so I hope somebody here is able to help me.
I recently finished a project in CS 5.0.3 containing a lot of clips coming from DVDs which contain 5.1 sound which Premiere neatly converted to stereo tracks. Today I opened the project again to make some final changes only to find that the audio was not working as it did before. Suddenly the downmix Premiere does is missing the center channel. If I import a new clip an manually deselect all of the other channels only then I can hear the center. I tried creating a new project but it behaves just the same: the source monitor seems to playback the sound without the center, but if I drag the clip to a stereo track it the downmix seems correct.
This is all very odd, considering that nothing was changed. Maybe some external codec that has to do with how Premiere downmixes the audio? Hope somebody can help me out with this.
Thanks, dave

Dragging the clips which contained a 5.1 mix to a stereo track
To the best of my knowledge, that is not possible. A clip will only go on a track of the same type.
These are mpeg2 files containing an ac3 6-channel mix. Previously Premiere seemed to handle them as stereo tracks (the information on these tracks that I imported a month ago still reads "Compressed - Stereo", but Modify->Audio channels reveals there are 6 channels only two of them are selected L & R). If I now reimport any of these tracks Premiere suddenly says "Compressed - 3 Stereo". I suppose that this difference in handling the ac3-audio has resulted in the missing tracks.
Could anybody tell me how their version of Premiere handles files with ac3 audio?
Does Premiere rely on any extrenal codec to decode ac3 audio? It might have been that this codec was updated on my machine and now produces a different result?
Thanks again, dave

Accessing center channel in Sony AVCHD video AC3 audio (5.1 surround)

I have tons of video shot on Sony HDR-CX7 and HDR-CX12 camcorders (AVCHD) in 5.1 stereo. iMovie '09 and Final Cut Express import the audio as two channel stereo, which is normally fine for a consumer app.
I use a Sony wireless microphone to record interviews, and I normally set the camera to record only the monophonic microphone audio. But, there is also a setting to let the camera record 5.1 stereo from it's built-in microphone, and use the wireless mic as the center channel audio.
I have footage recorded this way, and I find that when I play it back in stereo, I get a slight delay/echo caused by the wireless mic recording voices, and the camera recording voices (slightly offset). I cannot use the audio this way.
I want to extract the center channel audio from the AVCHD .mts files. I can then line that audio up with the video in Final Cut Express (or even overlay it in iMovie '09).
Does anyone know of a free utility that can strip out audio from AVCHD files?
It looked like Handbrake might work, but it errors out when it tries to convert more than two channel audio.
I believe the AVCHD audio is AC3 format, so if I can strip that out, Quicktime is able to mute the other surround channels.
Any tips?

Here is my current status, and a work-around method to accomplish this.
First, using "ffmpeg" it is possible to extract just the .AC3 audio stream from a .MTS AVCHD camcorder file. I have tried to do this with the Mac OS X GUI version, ffmpegX, but it errors out. It looks like it is sending the wrong parameter to ffmpeg internally (or perhaps it is using a different ffmpeg command I have on my machine). Anyway, the command looks like this:
ffmpeg -i 00000.MTS -acodec copy audio.ac3
That will extract just the audio stream from within the MTS file (which is an AC3 file). By default, you cannot play .AC3 files in QuickTime. It turns out, I had "Perian" installed, which is an extension for QuickTime that allows it to play a bunch of other files. One of the settings was a Stereo mode, which was causing anything I tried to play mix down to stereo. Aha! So, I could toggle that off and actually get to the audio track I wanted.
BUT, since native Mac OS X does not read .ac3, my workaround is to again use ffmpeg to convert the .ac3 file to a .aac:
ffmpeg -i audio.ac3 -acodec ac3 -ab 512k audio.aac
Since the source AC3 file was 448kb/s, I just manually chose 512k as the conversion rate, so it shouldn't lose too much quality. That value can be changed to decrease file size.
The end result, "audio.aac", is now a 6 channel 5.1 audio file. You can open it in QuickTime, and go to Window->Show Movie Properties then select the "Sound Track" track, and the "Audio Settings" tab of that track, and you will see tracks 1-6 (Left, Center, Right, etc.). You can toggle the tracks off to get to the one you want (in my case, just Center).
From there you could export this out to a file with just the track you selected, or drag the .aac file in to Final Cut Express.
If you drag in to Final Cut Express, you will see it takes up five audio tracks. I drug this under the original imported video track, and was able to mute the ones I did not need. I also found I could unlock the audio from the video, and then delete the ones I didn't want, just to clean up the edit window a bit.
The end result is now I can import the AVCHD file in to Final Cut Express, and bring in this converted AAC under the video to access just the center audio I wanted.
When I have time to streamline this process a bit more, I will update this topic.

Audio bleeding to center channel from left main on X-fi Elite

Erg! I was testing to see if I would like the x-fi as a pre/pro for about a week now. I?have been using the digital out since?I got the card an?it was working great for some time.. Now, using the analog outs, the center channel doesn't work and left ch. bleeds into the center. In the THX setup, If I play noise to the center nothing happens but play the left main it comes out of the left and center. I have the x-fi feeding into the Ext-Decoder source of my denon so its basically just being used as an amp. X-fi is configured to internal decoders with 5.. All the features are off for debugging(crystalizer,3D, ect..).
I fired up the THX optimizer in the Cars dvd to test DD and DTS and same result(theatertek, windvd8). It does the test tone for each speaker and when it gets to the left main it also comes out of the center. When it sends test tone to center speaker nothing plays. Its like my cables were crossed (somehow )
I switched the settings over to 4. in x-fi and it properly sends center ch. to left and right mains.
Am I missing a step?
I made sure control panel was synchronized to X-fi just in case. I have tried uninstalling and re-installing drivers and s/w (XP).
Maybe my card went bad ? its only been 5 monthsAny ideas what to look into?I have been searching for a long time now and couldn't find anything on creative or avs. Thanks for the help!

?Update: Well, i figured out it is wired correctly because if I go into "gaming mode" it works properly. I have the problem when in entertainment mode or audio creation mode. I tried to replicate all the settings in the gaming mode into entertainment mode but still no go.. Update 2: I uninstalled all x-fi sofware and took out anything in the registry. After reinstalling, it worked like normal. I then started fiddling and somewhere in my "fiddling" process I noticed?the sud?wasn't working anymore. What was happening before is now mirrored back to the Suroundleft/sub. So now the subwoofer is playing whatever the SL is playing and the sub channel plays nowhere. I went into Game mode and it worked untill I went into the?bass management. hmmm..

Center channel audio bleeding into left channel

When working on the audio mix for a project I discovered that dialogue would bleed into the left channel for some reason although the panner is set to center exclusive for that track. Can anyone else replicate this problem or can an expert chime in to confirm if this is a bug? It's definately bugging me
EDIT I am on 2014.2

with Premiere Pro CC 2014.2, build 8.2.0, I do not have any success with the center channel isolated with the stereo or mono audio
how about a work around with using an adaptive track, then channel output map the stereo input 1 and 2 both to output 3 (center channel)

Send stereo audio to center channel

I know I've done this before but can't remember how. I want to send the L/R audio to the center channel as a lower volume mono track. I thought all I did before was change 2/0 to 3/0 but it's now not working.

Audigy 4 (Non Pro) and center channel surround sound - from 2 channel aud

Hi all,?Is there a way to have voice coming from the center speaker during TV programs like you could using an external receiver with Pro Logic? I can't for the life of me, get my Audigy 4 to do this. I run MCE 2005 on a couple of machines in the house. On my other machine, with built in audio, I let the Purevideo decoder handle this and I get? a nice surround, complete with center channel voice on it while watching TV. On the machine with the Audigy 4, not only will it not give me the center channel while watching TV, but I can't get it to stop processing the sound so that I can simply use the decoding of the Purevideo Decoder... Stumped!?Thanks,?Stu

Various types of sound out of center channel on

So lets see, quicktime movie trailers, music in winamp, games,?MSN nudge sound, ?-they all come out all 5. channels (Z-5500s)?But the audio for flash movies I've had on my computer, some WMP videos, MSN new message sounds - these are all center channel only - and werent on my last system.
another thing - if I change the audio settings under control panel to quadraphonic - they do come out all the speakers, back to 5....... center channel only. its very distracting and stupid to not be utilizing all the speakers for things like a video. whats the deal here? Thanks for the help in advance.

apparently the issue might be that the X-Fi/console just plays mono encoded material through center only?
i preferred when it utilized all the speakers for things like that anyways on my audigy gamer...
is this the case?
edit: CONFIRMED. I found the msn sounds, and haha the NUDGE IS STEREO and the TYPE is MONO. Explains everything! now to get Creative to fix it....
Further:
with CMSS3D off, mono will play over both R and L, just with no seperation of course. (but then your rears center will never be used by pretty much anything outside of games)
with it On XPAND, it will play through center only. (4 not being used)
with it on SURROUND, it will play through center and rears, but not front L and R. (the 2 most important ones arguably not being used)
seemingly on my Audigy , all speakers would be used even for mono sources. So am I correct in guessing they changed things?
All speakers should be used for mono sources.
Can creative update this in a new driver?
EDIT: ARG I just found out it only happens in "entertainment mode" at that! Game mode does 4/5 (not centre). What is the reasoning for this?Message Edited by deusfaux on 03-0-200609:2 PM

Center channel is

So the problem is, I have X-Fi ExtremeGamer Fatalty and my center channel is very quite - barely hearable. I've done pretty anything - reinstalled drivers, reinstalled console launcher (now installed those beta drivers and console), gone through various configurations (enabled disabled CMSS, tried to manualy boost the center channel volume, bass redirection) nothing hel
ps.
At first i thought it's Speedlinks Medusa home fault, but it isn't - it works fine with integrated soundcard and with the old Audigy 2 ZS.
The only workaround wich works, for some reason (unknown to me), is when i half-plug center channels jack. Is this the fault of software or hardware... or both?
And yes i've searched through forums and still haven't found any good solution for this.

mine is too...center is pretty quiet, the only way i've gotten mine to work is the upmix option on my speakers...but as of today those don't work either(creative as well).

X-Fi center channel distort

I think there is something wrong with my x-fi's center channel. It sounds like the sound is like underwater and it gets louder and quieter randomly. I tried with my speaker and headphone so it's the X-Fi I believe. Anyone else have this problem? I'm going to try and RMA

I started having similar problems. The analog audio is very distorted but digital audio is fine. This is a XFi-Music card I bought 3-4 months ago. I cannot use the headphones because of this. I have tried reinstalling drivers and switching the PCI port but nothing worked.
For now I am using the digital out and using the headphones through the speakers.

Audigy And 5.1 Sound In Quicktime 7-- center channel doesn't wo

I've posted this on Quicktime's website, but it doesn't seem to be a problem with other soundcards. When playing a Quicktime7 movie with 5. audio, the center channel is silent on my Audigy card. Games, etc. all utilize the center channel just fine.
I don't know who is to blame, but it's really really annoying. Creative should work with Apple to make sure things are 00% with regards to this.

5.1 X-gamer and center channel of 5.1 speak

Hello,
first post may as well be a good one..
Ive read the FAQ and tried the options listed. im working with a week old install so not much on the dri've other than world of warcraft and MS office. Im running windoze XP pro on a AMD Sempron 2500+(.75ghz) with gig of ram and a nvidia GEforce6800GT video card. I have had this sound card a while, like 5 or 6 years. Ive connected a brand new Logitech X-5530 sound system to my X-gamer 5. sound card. everything sounds awesome excpet the center channel. Ive connected the center channel to the main output jack and got sound, so i know the speaker is functioning. the sub and center channel share a line on the X-530 speaker wires and the sub is working. however i get no sound out of the center channel. I tested this with the Creative Audio HQ panel set on 5. speakers. all other channels i hear the "front right, front left" etc... but center channel is totally silent.
any ideas?

Hmm, first go through windows control panel - sound and Audio Devices. Ensure you card is selected in all setup menus.
If "use only default devices is ticked, untick it.
Try S/PDIF and see if that works.
D/L this program - ?rightmark-3dsound-2.2 and run it just to tes things.

SBLive! 5.1 - center channel so

SBLi've! 5. card. SB0220
Serial number: MSB022846003453Y.
Yes, I've read about how this is an OEM product, (which kinda surprised me, this was NOT a prebuilt system from a big company, I chose most of the parts myself... but not really feasible to check up with my supplier now, it's already 3 years old).
Anyway, been kinda making do without my center channel, (It works when testing the speakers with the Creative software, but not with anything else), but finally decided to look up on it. So far the only fix I've found is using CMSS, which I FINALLY managed to locate (you can only get to it from the player view of the PlayCenter, nowhere else - very poor design!).
The thing is, isn't CMSS only an upmix, not really true 5. sound?
I'm fine with using CMSS for audio, music or otherwise files. But I'm playing a DVD which has 5. audio (The Incredibles : Special Edition), and it still doesn't output anything through the center channel with CMSS turned OFF. Same thing with 5. enabled games.
Oh yeah, been playing DVD in Windows Media Player b. Tried PowerDVD, but the ver bundled with my hardware only supports 2-channel, or SPDIF, again, not what I want. I want my 5. soundcard to output true 5. sound!
PS. [rant] It's really quite decepti've, as we can gather from all the complaints about this. The soundcard is sold/badged as a Creative SB card, but Creative can't/won't provide support for it. Why not then just rebadge it as a Dell/HP/whatever soundcard? Sure, I now understand what OEM means, but the average user will not, not until it's too late. [/rant]

I'm totally with you on this one. Please see http://forums.creative.com/creativel...ssage.id=77996. It's another thread that I'm involved in dealing with the same issue.
We can't figure it out - other than this conclusion that the product is either not working properly or not working as advertised. It is possible that recent drivers editions have screwed something up too.
CMSS is an upmixer - not true 5.. You can prove this by setting to 2 channel sound in a software program and leaving the hardware setting as 5. Disabling CMSS will will result in 2 channel sound.
My product ID is SB0350.

Center Channel Dialogue Editing

Hi all, new user here, this is my 1st post, so be gentle
I have been trying to use Audition to edit dialogue in film. I have isolated the center channel where dialogue is supposed to reside and editied the dialogue. Is there any way I can now rejoin the edited center channel to the existing left and right channels?
I also have another question you audiophiles may be able to help with. Is there any way of decompressing Miles audio wave files without sheeling out $3000 for Miles tools?
Thanks for any replies

Your speaker system has a centre amp which is more than twice as powerful as the front left/right am
ps.
Maybe it's made to be a bit more robust, therefore not so good quality. That's the only thing I can think of. Also, you don't need CMSS enabled when playing EAX games, it won't sound right. CMSS is just for upmixing stereo sources.

T7700, center channel, full speaker support

Hey all,
Just picked up the Inspire T7700 system (looks great) and have got all channels but the center forward working thus far.
My audio card is the SB Live! Value, and so far I can see no software options to support more than four speakers:
http://dmzweb4.europe.creative.com/S...,Case=obj(273)
Under "Testing your audio card with a pair of headphones or analog speakers," software options are shown that I just
don't have under my Creative Surround Mixer (speaker setup for 5.1/7.1). Presumably the options I'm seeing at the above
URL are within software for a different sound card, but the page doesn't state this. The T7700 isn't supposed to come
bundled with software (I did update to the recent driver pack and PlayCenter and no soap), so what driver package
provides options to support more than four speakers? (i.e., I need the drivers for full support of the 7 speakers for
the T7700). Also, at this URL:
http://ask.americas.creative.com/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=ww_english,Company={CEAE26D-879-4C00-AC9F-03BC258F7B70},VARSET=ws:http://us.creative.com,case=4883
It mentions that CMSS is supported by the Live! series cards. I have the 5.1->7.1, 6.1-7.1, and 'direct' CMSS options
on the sub -- changing this setting doesn't give me my center channel (i.e., I read another thread where someone got
their center channel working through adjusting the CMSS setting -- this didn't work for me). What am I doing wrong?
Thanks,
-Chris

The Live! Value sound card support up to 4.1 analog speaker. Therefore there would not be 5, speaker option in the mixer applicaton. Perhaps it times to upgrade your sound card to at least a 5.1 speaker support or 7.1 speaker support since you have a 7.1 speaker.
The Audigy 2 ZS sound card would be able to support up to 7.1 speaker.

S750 muffled sound front/center channel.

Hi there,
Roughly 6 months ago I purchased a set of the Creative S750 speakers. Upon reading the various horror stories, precautions were taken to ensure longevity. The speakers have also never exceeded half volume.
It looks like this still hasn't put off the inevitable. Recently the front and center channels have become muffled, upon inspecting further I was taken to the conclusion it was most likely the sound card. However, after removing the X-FI and activating the onboard audio it seems the issue still remains. The front channels sound bassy with no tweeters.
Notably, headphones that are plugged into the control pod sound fine, which would point to the preamp and main amps being ok.
The speakers are only a few months old, and they have most certainly never been abused. What could be the issue that is causing the muffling of the front speakers?
Nevermind, I found out exactly what this is, I'll leave this post for anyone else that has encountered this issue.
On further inspection of the faulty speakers, it turns out that the crossover circuit inside the speakers is the issue. The circuit itself would seem to be damaged. This could mean two things:
-This is not actually a brand new set of speakers, and they were damaged by the previous owner.
-The build quality of the speakers by the manufacturer is exceptionally poor.
-Also I observed that the internal shielding underneath the woofer is missing in 3 of the speakers which also goes to prove that they are a recon set.
I would normally expect neither of the above to be true after spending 360 on a BRAND NEW set of computer speakers and getting a refurbished set instead.
I hope this post will help anyone else experiencing this problem.

Hi there, I've had no problems with my sound system for 4 years until today. I hope someone can help. I have Creative X-Fi Extreme Gamer soundcard and S750 7.1 Giga Works. Years of great sound. Today I have no sound from my sub and muffled and low volume for the center front speaker.
All other speakers work perfectly. I switched the green an orange cables from the sound card and the sub with exactly the same results. I think this means the cables are okay. How do I tell if I got a defective sound card or sub? I suspect that either the amp or sub is defecti've but don't know for sure. If that is the case is it worth repairing or should I get another sound system? I can't seem to find the S750 for sale on Creative's website. Any advice will be greatly appreciated. Sincerely, tangone
