Split Stereo to Two Mono Tracks - Need Help

We're having trouble with STP working with two non-stereo tracks.
We have footage that we're editing in Final Cut Pro that was captured with two separate mics providing the audio. (A wireless lav and a shotgun.) The sequence is set up with two mono tracks.
When sending the project to SoundTrack Pro, it's opened up as a pair of stereo tracks. We cannot find a way to edit just one of the tracks without it affecting both at the same time.
How can we separate the tracks so they can be tweaked individually and then sent back to Final Cut Pro?
Thanks for any help you can provide.

...and when doing that, make sure when you export, you don't fall over one of the many bugs in STP:
You will probably find that the clip with the right channel selected actually plays the left channel after being exported (sound fine on the timeline - problem only on the exported file).
The solution is to
1) duplicate the stereo file and place on new track (as suggested)
2) select left channel on first clip (control/right click the file)
3) select second clip and swap the L and R channels around (Process-> swap channels)
4) select left channel on first clip (control/right click the file)
Oh the joys of STP!

Stereo -- two mono tracks

hello!
I had a question about importing a stereo track. I'm in a stereo multitrack right now, and open a stereo track in that, but
I'm still not sure how to split the stereo track into two mono tracks.
Right now it's just playing on the Left side of the headphone. How do I get it so that there are two tracks - one on top of the other?
Help?
Thank you for bearing with my training wheels here!
Best,
Trail

I'm not sure why you want to do this. If you put a stereo track into a stereo session, then it will play in stereo. If you want to alter the relative left and right levels of the track, you use the Pan control in the mixer. If you can't hear both channels, then you need to check the mixer's master output options (where it says Default output at the top) and make sure that you have a stereo option selected - if you don't have this selected properly, you'll definitely only hear one channel.

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.

How to put two mono tracks into the usual stereo view in Edit view of Audition 3 ?

Hi guys,
Previously I have had no issues simply using Adobe Audition 3 for simple stereo recording and editing of a stereo feed taken from a mixer... well nearly no issues.... :-)
Today, I'm having a bad day or else it's because I'm getting used to being retired.. :-) ......
Query : How do I put two mono tracks into the usual stereo view in Edit view so they both display correctly there?
Put simply I have two mono wav files. Let's call them Left_wav and Right_wav.
I cannot seem to get them imported into a new clean Edit view (Normal stereo track layout) so that Left_wav is on the top half and Right_wav is on the bottom half.
Whenever I try, I just get either Left_wav or Right_wav taking up the whole of the edit view. i.e. it just shows one track.
Can anyone familiar with Audition 3 kindly help? I'd appreciate a simple step by step... I just can't see where I've been going wrong, and it's driving me bananas :-).
Thanks

There are various ways to do this in Audition 3. here's one.
Open both mono files separately in Edit view. Then convert Left_wav to Stereo by going to Edit/Convert Sample Type and under Channels select Stereo with Left Mix at 100% and Right Mix at 0%. This will give you a new stereo file with Left_wav on the top channel. Next go to the Right_wav and copy to the clipboard using Edit/Copy. Return to your new stereo file and enable Edit Right channel only in Edit/Edit Channel/Edit Right Channel. Then make sure that the cursor is at start of the stereo file and Paste Right_wav into the bottom channel of the new stereo file. Finally Save As.

Making two mono tracks from one stereo track?

I've used the M-Audio MobilePre USB device to record vocal and guitar at the same time. In GarageBand, this inputs as one track, with guitar on the left channel and vocal on the right.
I'd like to separate this one stereo track into two mono tracks for further mixing and editing.
Any ideas on how to do this?
Thanks!

Convert two mono tracks into one stereo?

I've imported a clip from my DV camera into Final Cut. For whatever reason, the clip audio is two mono tracks rather than one stereo track. Is there a way for me to convert this to a stereo track after the import?
Thanks very much,
Greg

Select both clips in the Timeline, then go to Modify->Stereo Pair (Option L). But if both clips contain the same audio information, it won't really be stereo ... just two tracks panned left & right.
If you want the audio to come in as stereo when you capture next time, make sure that you have the Capture settings for the audio set to "stereo."

Two mono tracks - one stereo

How could I join two mono tracks (wav pcm) to one stereo without quality loss using ST Pro 2.0? If there is no good way to do this, could you recommend something, that can. Thanks

Not sure what you mean by joining 2 files, but if you export as the same bitdepth and samplerate and leave the faders at 0 VU there shouldn't be any quality loss.

Joining two mono tracks

How do I join two mono tracks to create a stereo track? Somehow when I exported my project from FCP, the stereo music clip ended up as two mono clips... Instead of showing up on track A7&A8, they show up individually on track A7 and track A8, which makes changing levels and keyframing a pain!
In the same vain, how do I split a stereo clip into two mono clips?
thanks in advance!

Yeah, too far in on my STP to go back to FCP and re-export. Did find, however ctrl-clicking on the clip, and selecting channels that way to be of help.
Thanks for the reply!

Two mono tracks

I think I may have a blind spot, but here goes...
I'm attempting to export an audio clip into Soundtrack Pro, but am unable to because I either recorded/captured the audio as two mono tracks (L & R). Is there a solution to editing the audio in STP, such as creating a stereo track? I'm not especially proficient in sound editing (as my post suggests), but I'm assisting on a project that needs the noise reduction feature in STP badly, and due to the track settings.
Suggestions, comments?

hi there,
Select your clip in the sequence and hit alt+l.
Then you can use the sent to soundtrack pro function, wich you can find under File, sent to.
good luck!

Importing Stereo File to Two Mono Tracks?

I have a stereo audio file. I'd like to put it into GB2 with one side of the stereo file as one mono track and the second side of the stereo file as a second mono track.
Is there any way to do this?
Thanks,
Leon

Leon, Here is a file explaining what Monomaker does.
Monomaker is a simple mono-merging and stereo-recentering utility plugin.
You can use the mono merge parameter to progressively merge your stereo audio channels into a single mono signal. Turning mono merge all the way up to 1 will make your sound completely mono. Turning mono merge all the way down to 0 will leave your audio unaffected.
You can then recenter your signal using the pan parameter. The panning is equal power (meaning that as you move further over to one channel, sound from the other channel is copied over to the first channel in order to keep the total volume consistent).
Also, in case it's useful, you can re-route the 2 input streams in a variety of ways by using the input selection parameter. "Left-right" means that everything is normal, "right-left" means that the left and right streams are swapped, "left-left" means that you lose the right stream and get the left stream copied to both inputs, and "right-right" means that you lose the left stream and get the right stream copied to both inputs.
Monomaker's signal path is input selection first, then mono merge, then pan.
I have just downloaded it myself and have not looked at it yet. I apologize in advance for not checking it first before posting it. It may or may not help you, and I do not know if it works in Garageband.
Here is the site I got it from

Two mono tracks to create a stereo tracks

I have a series of piano music a cousin made, but it is all mono. Is there anyway to double the mono track to make a stereo track for CDs?

Yes, you can fake a stereo recording. Duplicate the track, option-drag the region into it, then offset it slightly from the original, and finally pan one track left some, and the other right some.

Stereo to two monos

I've tried to find this function but I couldn't find it. How can I split a stereo audio file on a stereo audio track into two monos so that I can route the left signal to one bus and the right to another?

Thank you very much. By the way, what does I/O buffer size in Preference>Audio do? What's the advantage/disadvantage of having it small or large?
This is another question??
you should be open a new post... in order that other user.... anyway...
Are you talking about _"Small-Large buffer"_ so the correct thern is *"Buffer Process Range Setting"*
this is related with the multiple 32 bit floating point audio engines inside Logic...
Process buffer is connected between _Audio and Software Instrument Tracks_ and AUX/BUS Channel strip section...
Process buffer set as Small reduce the latency that occours when you use a Buss for use FX such as Space Designer...
*But Small setting increase the CPU power request.*
if you set Buffer process setting as Large the latency will be higher *but less CPU processing power will be required*
This buffer can be also helpful for reduce the CPU power on slower Machin such as G4/G5 or Macbook and iMac in soma cases.
(on the new Nehalem this must be set as Small and... should be a great advantage if in the next release this setting should be smaller... because the RAM DDR3 at 5GHZ without front buss side is very faster and requires to be reduced over than actual *Small setting*!!!!)
*The Buffer Processing setting is strictly related with PDC setting*
and The CPU-RAM speed
When PDC is set to ALL the live recording latency will be = Buffer sample size + Buffer processing Range size...
So that is why I always suggest to avoid to use PDC set to ALL when recording/tracking
+Anyway your additional question is OUT Thread... a new post should be opened.+

Stereo to individual mono tracks?

GB doesn't seem to be able to split out a stereo sound file to left only mono and right only mono. I've gotten around this issue by creating a copy of the file and panning one track left and the other right. Selecting Mono channel 1 or 2 input in Info just merges the both tracks together into one mono track (for some reason), panning just sends the combined signal to the L or R. This solution is fine while editing in GB, but is bad for the final output where not only would I like to preview the combined audio tracks to set levels, but also export them so that the left channel material is on both tracks of the final stereo file. Here's what I'm dealing with so there is no confusion. I am e-mailed a stereo file with vocals on L and temp music on R. I replace the temp music with several new options. Then I want to export the new mixes back to a stereo file with vocals centered to send for previews. GB does not seem to provide e with a way to do that. In other words, there does not seem to be any way to get the L channel of a stereo file to the center of a new stereo mix without also combining it with the old unwanted R channel material. I'd love to find a way. One solution would be to flip the L/R orientation of the copied track and play the vocals back panned respectively on two tracks, but that's also something that seems beyond GB's capabilities. So there's a new one ... how to flip the stereo field of a track, which would be an easy fix to this problem ... I'll post on a separate thread.

One way to do it would be to
1) pan the stereo track full left, and export.
2) set iTunes' prefs to convert to a MONO AIFF file, do the conversion
3) drag the new file into GB.

Stereo to 2 mono tracks conversion problem

The problem I'm running into is that once i've split the stereo track into 2 mono tracks, and bring the one mono track back into logic express to use, it still recognizes plays as though it's a stereo track.
The stereo track that i'm using basically has the music on the left side and a metronome on the right side so we can use it for backtracks through an ipod in a live setting.
I've also ran into a similar problem after i edited some audio tracks I was using in a sample, after i edited it and brought it back into the proram, it didn't want to recognize the origional track that i had...
has anyone else ran into this or knows what i'm doing wrong?

Is this possible in iMovie 9?
Yes, it is.
In iMovie choose Share>Export to QuckTime. Choose Export: Sound to AIFF then click the Options button.
From the Channels dropdown menu select Mono. Click OK and then save the file to the Desktop.
Detach and delete the original Project and drag in the newly created file and place it on the video in the timeline so it imports as a connected clip and not just in the background.

KILLING AN OLD ACCOUNT--TWO ACTUALLY. NEED HELP BA...

I have 2 old skype accounts that I want to kill. This is a real PITA not having a customer service agent to call. Need help on this, because I established a new account, but when I sign in to skype it defaults to an account I'm trying to kill. Using 8.1

If you're sending from the new account, that address is the outgoing mail address, by default. Did you try deleting the server of the old account? It could be sending mail out through that server instead of the one provided by the new ISP, which would change the outgoing mail address.
Go to Preferences > Accounts and select the new account; look near the bottom of the window where it says "Outgoing Mail Server (SMTP)" and check to be sure that is set to the server provided by your new mail provider. If it's not, you need to select the correct one from the pop-down list.
