Stereo becomes mono after rendering audio

Hi,
I used stereo clips in a normal timeline.
They play stereo. OK.
BUT
If i add any audio effect AND render the audio, the sound becomes Mono !!!
What am i doing wrong ?
thanks !

Convert the Xvid material to DV-AVI Type II (for SD material), as PrPro will never likely be able to handle it properly, if at all.
Also, it is very heavily compressed, and is a delivery-only format/CODEC, and is not meant to be edited.
Good luck,
Hunt
PS - this ARTICLE will give you a bit more background on CODEC's. If you have to edit Xvid material, you might have much better luck with CyberLink's PowerDirector, as it handles Xvid (and DivX) footage better, though that major quality hit will still be there - no way around that.

Bass Sounds---Stereo to Mono

I've been using GB3 now for a week and I created some nice stuff but there was a problem with this one track and I didn't realize what was bugging me about it until I realized that the Bass sounds are in Stereo (at least all the sub synths i was using). Like, it's excited between both speakers. I tried using the Izotope Vinyl plug-in (Free @ Izotope.com), putting it in Mono but then like every 25 seconds the bass will slowlyl go out of phase and then get in phase.
Any suggestions based on anyone's experience to get these bass sounds in Mono? Or does anyone know which are the best mono bass sounds? (I'm a lil lazy--LOL)
Thanks GB Fam!!!

HangTime,
I went and downloaded both wiretap and monomaker and they both fixed my problems-----especially the monomaker!!! I gotta give it you man cause I had no idea how I was gonna resolve that bass to become mono and not phase out or move to one side----Monomaker is amazing--it completely did the trick.
I used it with Roger Nichol's Inspector plug-in (free also in case you don't know about it--Roger Nichols.com i think--or just google it) to check to make sure that the bass wasn't moving a fraction to either side-Everything looked and sounded perfect!
Thank you----Much luck in all your endeavors!!

Switching from stereo to mono...

is there a way i can switch from stereo to mono for recording volcals in garageband?if so...how??thanx much

In the Track Info window where you select your instrument or preset, you can also select the channel through which you record - either one channel (mono) or two (stereo). Set it to one channel.

Stereo to mono

how do I switch from stereo to mono in FCP?

also make sure you do not have "Downmix" enabled ... it is toggled On/Off by using the Downmix button in the Audio Mixer window, it looks like a bowtie, and sits just above the Master fader.

Could that have something to do with why I got no sound out of the external monitors (speaker)?
it's possible, if for instance the track was set to channel 1 (mono) and you were sending a signal on channel 2 (or any other channel your interface might offer), but you may want to start a new thread with this issue providing all background info for it

Can Compressor downmix from stereo to mono?

Seemingly simple question - when compressing DV/AIFFs to web H.264/AACs, is there a way to downmix from stereo(dual mono) to mono without boosting the level?
I don't care if it just uses the left channel, the right channel, or mixes both together - I just want it not to clip 0dB when it comes out mono. Is there a way to do this in Compressor?
(NOTE: without using the Peak Limiter filter to lower the level, which always seems to cause the job to fail)

First you have to split up the interleaved stereo file->in the Audio bin select "copy/convert" (or hit control+c) in the menue select "Interleaved->split" and tick the box "add to Audio bin"
Now switch Audio track 1 to "Left" at the very bottom of the channel strip->long click into the stereo symbol->menue opens->select "left"
Do the same on Audio track 2 in this case choosing "right" at the bottom of the channelstrip
Now select the reimported split stereo file in the bin and split it up into two seperate files in the edit menue->"split selected Split-Stereo-file"
You now have created two independendent files for left and right and can drag those onto your Audio tracks 1/2 in the Arrange - of course you need to pan track 1 to the left and track 2 to the right to retrieve your original stereo image

I've been editing NLE for over 15 years and have never once used a "mono" track, never felt a need to, and Premiere tracks default to stereo normally, which matches my sources. All delivery is typically stereo anyway, so in the case you have with wanting to use just one mic, the Fill Left or Fill Right works perfectly to "Pan Center" so to speak. Hopefully this will suit your needs. Maybe I have tunnel vision and am not understanding how a mono track is uniquely useful, but always open to learning new things.
In the situation where I might need to switch mic sources from time to time within the same stereo clip, for instance a wedding with a shotgun and wireless lav, I just use the Razor to put cuts in the audio clip where I want to switch. I just alternate applying Fill Left or Fill Right to each cut segment as needed, and throw in an audio crossfade at the cut point for a smooth transition.
If I need to MIX the left and right channels in varying degrees of volume, I will duplicate the stereo track and apply Fill Left to one and Fill Right on the other and this has the same effect as two mono tracks, each centered. There's certainly many ways to accomplish the same thing with almost any aspect of editing and that's just how I do it, not wrong or right really.

How can I switch my output audio from stereo to mono?

Hey,
I can only hear out of one ear and I would like to be able to listen to the other half of my music on my headphones, how can I switch my audio from stereo to mono?

I'm deaf in one ear and need a stereo-to-mono earbud so I can use my iPod and iPhone. It is not good being able to hear only one channel. Can Apple consider making such a thing for those of use who need such a thing?

I'm not sure which version iPod you have, but I just checked my iPod nano (current generation) and it also has a Mono Audio setting in Settings>General>Accessibility.

Stereo-to-mono glitch when match-framing

While searching for an answer I found a posting from ChiaMac dated Nov. 15, 2005 which describes the same problem I am experiencing. I have pasted the post below. Does anyone have an answer ?
Hi,
Three different editing systems, all running OS 10.3.9 and FCP 4.5 -- an iBook G4, PowerMac G5, and PowerMac G4.
Quite often, when match-framing in the timeline to bring up a clip in the viewer, the viewer will show dual mono audio, whereas the source clip has stereo audio. Then, when I try to cut that viewer clip into the timeline, in this sequence or another, it will be dual mono. Quite irritating.
It is quite replicable. Not all clips will produce the stereo-mono result, but it is replicable with the same clips over and over.
The "linked selection" has no effect on the process, no one has pressed command-L by mistake, and all audio settings on each of the systems are set to capture and output in stereo.
Is this a known FCP 4.5 HD glitch? I haven't seen it listed anywhere when I've searched for it. Any ideas, suggestions...?

>When converting a file from stereo to mono, Audition severely suppresses the amplitude of the entire file. This happens when using both the Convert Sample Rate method, as well as exporting a file from multi-track.
>It gets weirder: files that were recorded quite a while back will process this conversion just fine, but newer ones will not. All files are recorded in 16-bit 44100 stereo and saved as a Windows PCM wav file - so as far as I can tell there is no difference and I'm simply confounded.
Generally when this happens, it means that there isn't that much stereo (ie, difference between the two channels) in the file anyway, and one of these two channels is inverted - so that what happens when you combine them is that the 'mono' parts then cancel out, rather than add together, and all that's left is the difference - which looks pretty much like what you've got.
To test this, the thing to do is to select one channel only in EV, and invert its polarity (Effects>Invert). If you now get more like the waveform you were expecting when you convert to mono, then you've found the cause. But not necessarily the reason for it...

Re-Capturing Media with original settings but with Stereo not Mono Selected

Hi,
I am trying to re-capture about 17 hours of interviews that I just shot in Africa over the past month. It has all been digitized with the audio set to Mono instead of Stereo (in my jet lagged mindset I forgot to set to Stereo)! I need the stereo setting as I always had a wireless lav on the subject and a wired lav on the interpreter and I need to be able to split them out in the sequence. I have already built sequences with all the interviews and a timecode window burn for my client, which sounds fine for simple timecode logging, so I would like to reconnect so that all of those sequences will remain intact.
So when I try to go recapture, whether I delete the original clip OR just make it offline and save the new captured clip to a different location, it automatically captures in Mono, as that is what is set in the original clip under Audio Tracks in the browser. It will not let me change that setting in the Browser, and stereo is definitely selected under Audio Clip settings in Log and Capture.
I have to think there is a way to do this so that I can save my original clip information, without having to reset all new in and out points and recapture it all with the exact same name to a different drive so it works in my sequences.
I don't need to recapture the 18 or so hours of b-roll thank goodness! As it was all shot with a mono shotgun.
Also, when I go to recapture the clip a warning comes up and says I am trying to capture media shot in Non Drop Frame on a device set to Drop Frame..etc etc etc.
I did shoot in non drop frame but I have not changed anything on my deck (Sony DSR-11) and don't even think there is a switch to go between the two. If I try to simply capture a new clip I get no such warning? It seems to play fine regardless but I wonder if I will have issues down the road integrating the new clips in with the b roll.
Many Thanks,
Any help is greatly appreciated,
Peter Mallamo

If both tracks are in the sequence, then just select one side, and in FCP's Modify menu (audio submenu there), pan all to one side, then select the other track and pan all to the other... you can change the stereo to mono and mono to stereo too in that same menu... no need to recapture at all. Do this mono to stereo move simply by selecting the clips in the sequence, and checking on or off the stereo pair selection...

Stereo or Mono? Which? And why?

Once again I'm starting a new thread to explain some general audio principles that newbies have trouble with.
There's an issue here that's a bit difficult to explain--the difference between "stereo" and "mono".
You have two ears, so you hear "stereo". Your ears send a left signal and right signal to your brain. Your brain processes the difference between the two signals and gives you a sense of direction. You can figure out where the sound you are hearing is coming from.
Originally, recording technology only permitted mono recording. One microphone, and one speaker to play it back. When you listen to recordings made before about 1962, you are listening to a mono recording. If you have a modern stereo and you are playing back a recording from before 1962, you are getting signals out of your left and right speaker, but the signals are identical. You are just getting mono out of two speakers.
Originally "stereo" meant placing two microphones on something--one to represent what the left ear would hear, and one to represent what the right ear would hear.
However, when you take one microphone and plug it into a recording device, you can only record a mono track. Your recording device might permit you to record what you think is stereo, but in reality you are only recording two identical mono tracks.
A guitar also has a plug that comes out of it that sends a mono signal.
Nowadays we create fake stereo inside the recording device by means of what we call a digital reverb or digital delay. This device takes a mono input (such as from a single microphone or from a single guitar cord) and simulates the sound as if it were playing in a much larger room, with positional information included--placing something in a simulated position in the stereo field and creating a simulated left stereo channel and a simulated right stereo channel.
So if you record one input, and put no effects on it, you get mono. If you run it through a stereo reverb or a stereo delay, you get simulated stereo.
If you put an acoustic guitar in a large, reverberant room, and set up two microphones, one on the left side of the room and one on the right side of the room, and record the two mono mike signals to a stereo track on your digital recorder, then you get real live stereo.
When you play a software instrument in GarageBand, it records it as a stereo signal. What you are usually getting is in fact a monophonic sample that is processed through a stereo reverb, simulating stereo. In some cases, it may actually be a digitally sampled musical instrument that was sampled in stereo, with two microphones, like the example of the guitar in the reverberant room that I mentioned above. Software instruments of drum kits and acoustic pianos are examples of instruments that are usually sampled as real or artificial stereo to begin with.
Beginners think "stereo" is the right way to record, and "mono" is not. But this has nothing to do with the right way to record, and has nothing to do with wheter it's a high quality recording. If you are recording through only one microphone, or only one guitar cord, this is mono, and that's right.

Good points, Wheat. And when you record from several sources, and combine them and mix them, panning things to "set the stage" you get a stereo mix, of mono recordings. SI, the final result is stereo, not necessarily each individual piece of the recording. Of course, a drum kit can be recorded in stereo, as well as some keyboards that are actually stereo. But most things you hear on CDs are a compilation of mono tracks, panned to create the stereo image you hear.

Is iMac line in, stereo or mono

I'm hooking up my microKORG keybard to my iMac via the line in. I'm curious as to if the line in is stereo or mono.
TIA!
Wayne

It is stereo with a separate left and right. So, if you want both channels, then use a stereo cable.
They do make Mini-Stereo cables that have both left and right channels, so make sure that you get one of those. And, make sure that the device you are recording from outputs both left and right.
If you use a mono cable, you'll only hear audio through 1 speaker / channel.
Unless you specifically use a mono cable that hits both the left and right connectors on the jack.
