Changing Tracks from Stereo to Mono

Hey All,
I have a bunch of tracks I want to make a project out of, some are stereo and some are mono, I decided to go with mono, anyway to change the stereo tracks to mono in GarageBand or in a 3rd party app?
- Thanks Zach

Right, we don't have to start fighting about words. What I wanted to say is that audio editing is just a minor part of what GB does, and in order to keep it simple and easy to use for beginners, they kept the audio editing capabilities to a minimum (Logic, which is based on the same engine, can do a lot more). So if you only want to do audio editing, it makes sense to use a simple audio editor with all its strengths. The comparison to text editors is not bad: Word is a word processor and document production tool, and editing text is just a small part of it. So people who really want only an editor (e.g. programmers) don't use Word for their purpose but things like BBEdit that gives them more options for the pure editing part.
But you're correct, we're straying away from the topic, and I'm glad you sorted your problem out!

Changing track from left to right speaker

I recently acquired a Macbook with Garageband '09. I made a recording with two mics, one recording a guitar, and one recording a drum kit (They were both recorded at once on the same track). Since I had set the input to stereo, the guitar (mic 1) played through the left speaker, and the drums (mic 2) played through the right speaker. I would like to have mono sound, but I still want to use two mics to provide better clarity and prevent spill.
Is there a way to keep the track I have (guitar=left/drums=right) and perhaps duplicate it and switch channels from left to right creating a mono sound? Basically one track would be guitar=left/drums=right and the other would be guitar=right/drums=left. Or is there perhaps a way to switch a stereo recording to mono once recorded?

I would like to make a track mono, but do not see where in the "pane" I can do that. The only option I have found is to change the input from stereo to mono. Since I have audio that is already recorded, and is unfortunately only on the left track, is there a way to get the mix down to be mono so that I'm getting the audio in both speakers?

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.

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?
Thanks!

Windows 7 switches from Stereo to mono upon record start ?

I'm beginning to regret Selecting Windows 7 (64bit) OS for my new Laptop (HPdv6) (IDTonboard sound for now)
intended in large part for audio recording -- ignoring what I had read about audio problems in this OS optomistically hoping the would be fixed already. XP had always performed well for me. Here is my current problem which I've really been fighting for weeks in a Trial Copy of the current Audition without success.
Although I do have Ausio driver -- the built in Audition driver seems to work best , and I get everything ready to go selecting stereo 44100 16bit file to avoid confusing the many issues I've been having, press f10 to Double check in the edit window that I am actually getting differentiated separate stereo tracks --- then press record button --- and thats it -- from there on out two identical tracks that might as well be mono.
Again and again -- I have no idea why -- and with all of the problems I've had with windows 7 I don't really blame Audition --- but I would sure like to figure out how to fix the problem. I've all ready read Microsoft forums and there solution is to blame any third party software for problems that are very obviously within Windows 7 - so I'm not optomistic about looking for help in that direction (grin!)
thank you

So in the Edit View Hardware setup, what input setting do you have as a default? If it says something like [01M] then that's what you will record - mono on both channels. What you need is to select a default that says [01S], if that isn't what you already have. If it is - well, then I'm not sure what's happening at all, because for reasons that you've already alluded to, I'm using XP - simply because I'm a pessimist, and we get all the nice surprises if something actually does work...
Optimists are only ever going to get disappointed by the real world, I'm afraid.

From stereo to mono?

I can imagine this is a very simple question, but I'm yet to find the quick answer...
After importing some tracks, it has made a left and a right channel into one stereo track. How do I separate them out into two mono tracks??

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 did a "Bounce - replace all tracks" and now all my mono audio tracks are stereo... What's the safest way to get them mono?

I don't think I unchecked the "Include volume and pan automation" checkbox before the "Bounce - replace all tracks" conversion. I hadn't added any volume or pan automations I figured: you can't include something I haven't added, although I did probably have the pan controls set in the mixer. Anyway, now I want to convert my six (previously mono) tracks from stereo back to mono, preserving as much as possible the original mono sound quality before it was converted to stereo, so that I can start mixing. Every MP3 I've exported is ignoring the pan settings I have in the mixer, I suspect due to the fact that the audio for each track is now stereo (I changed the tracks back to "mono" in the mixer but the audio remains in stereo). Unfortunately I don't have any unused audio files in the audio bin and I killed the undo history as well.

Thats what I came up with:
As you can see I got a stereo file on track 1 to start with,
Now go to the corresponding channel strip and switch to mono,
Perform a BIP to a new track
and the result will be in mono.

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...

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.

Possible to Join Two Mono Tracks to Stereo, Or Change Panning of a Stereo?

In the new Garage Band 11, is it possible to Join Two Mono Tracks to Stereo, or Change the Panning of a Stereo track, or split a stereo track into two mono files?
Sometimes it would be convenient when I have a lot of tracks to combine two mono tracks into one stereo track to eliminate an additional track.
Also, I find that I often want to change the panning of a stereo track to either make it wider, or merge the two channels, even reverse L&R. If no way to change the panning of a stereo track can a stereo track be split into two mono tracks to be panned differently?

only by exporting the two tracks
or Change the Panning of a Stereo track
you can pan a stereo track in every version of GB with the pan knob
or split a stereo track into two mono files?

that's different. no, you'd have to split the track into two mono files as described above.
even reverse L&R.

When a project is sent from FCP, do all mono tracks become stereo?

It appears that when exporting a sequence from FCP, all mono tracks become stereo. Is this correct?
I have a mono voiceover on A1, and a mono set of SFX on A2, and then some other stereo background music tracks. When sent to STP, the two mono tracks show as being stereo files, when you look at the file information, and indeed, they have two waveforms displayed in the timeline.
Is this just the way it works?

Interesting link, thanks for that.
However, I have to say that was not my experience of how it ended up. I had two mono tracks, without panning, and when I sent it to STP, it ended up as 2 stereo tracks.
I would have to experiment a bunch to try and figure out why that happened, and at this point, I think I've decided to NOT use STP and just stay in FCP, for a number of reasons. Mainly the fact that once you've done a whole bunch of effect assignment and mixing, enveloping etc. to a multitrack project in STP, there's no easy way to move a few clips around (in FCP) or tighten up some video edits without having to manually calculate frame offsets in STP, and laboriously move things around and hope they still match up. Could be I'm missing something, I only used STP for a full day...
Maybe the update will make it better somehow.

Changing mono tracks to stereo

how does one change mono tracks into stereo tracks? I am using CS3. Can I do it in Premiere or Soundbooth?

Frank McGough,
In Soundbooth, Save As Wave format, and under the "Channels" dropdown select Stereo.
