Stereo tracks & busses

Hi,
For some reason, when I set up busses in my Logic 7.2.1, it only registers them as mono even if I click the circle at the bottom and it's showing the interleaved ST symbol. So, if I bring a sequence to my computer from another, I always get an initial prompt that says "tracks converted to another format." Similarly, if I make my tracks what appear to be stereo tracks and open them on another computer, while I don't get the opening prompt, the tracks appear to be mono.
When I go to set up a track also in the pull-down menu, I have options for aux stereo, output stereo, etc but there's no "track stereo" or "bus stereo" in the list, only in the mono list. So, I can never create a Bus 1-2 or Track 1-2, only a Bus 1 or Track 1. Any ideas? Thanks-

I noticed a similar situation today involving some apple loops I had dragged into the arrange window. The apple loops have a stereo symbol, but the circle at the bottom would not change to stereo when clicked. It seems that this happened after I had inserted a channel strip template (for effects) into the same channel as the apple loop.
It appears that the channel strip template changed everything to mono. I tried to work around this by placing the apple loop into the arrange window before applying the channel strip template. At the moment that the channel strip template was placed, the channel immediately switched to mono, and stayed mono no matter how many times I would click the mono/stereo button.
The solution to this problem was to not use the channel strip template, but instead to insert each effect individually one by one onto the channel strip, and then copying the exact settings of the effects that were on the template and then pasting them to the inserted effects. When inserting the effects, I made sure that the heirarchical menu went down the mono-stereo path (instead of mono alone). This worked, and the channel remained stereo. I also noticed a considerable improvement of the sound on the stereo track compared to the mono.
The bottom line... if you have any channel strip templates on the track (or bus) in question, then those templates may be for mono instead of stereo. The way to work around this is to insert the effects individually in stereo, then copy and paste the settings on the effects from the template to the effects.

Mixing Four Tracks To One Stereo Track

Hi,
In Logic 7.2.3,if I have recorded four backing vocal tracks, all doubled up, and I want them panned across the track, from left to right, is there a way that I can submix them to one stereo track, still keeping their pan positions, so I can apply processing to all of them together.
I tried doing this via a buss to aux track, but it only picked up one side of the stereo spectrum, which is no good.
I remember this was easy to do in Ableton Live, as you could directly output from one track to another track, but I cannot find this option in Logic.
Thanks,
Tristan.

Send them to a bus. Buses are stereo in Logic and you can apply the same effects to the bus that you can to any track. The output from the bus is normally the main ouput (though you can change it) so it gets back into the mix.
Perhaps the easiest way is to route the I/O of the selected tracks not to Output 1/2 but to Bus 1 and do that for all your backing tracks.
Another way is to click on the Send button on the vocals track and route to Bus 1. Then ramp up the send pot, but check your levels since you are now sending both the original track and the bus to your output. If you don't want the originals to go into the mix, set the tracks to no output or use the first method I mentioned.
You'll probably want Bus 1 in your arrange window. To get it, open the track mixer, click on Global (to display all the objects in your system), scroll to to the extreme right and double click on the label Bus 1.
Hope that helps!

Editing Stereo Tracks

Here's my situation; I want to be able to edit a stereo pair at the same time with all changes I apply to the left being applied equally to the right. I need to tweak some of the audio, take out background noise, adjust levels, etc. and my stereo pairs will only import into STP as two separate tracks. When I try to make changes to one track and then apply the same settings to the 2nd track it's too much and the audio sounds like crap. Not to mention it's twice as much work.
How can I get STP to make the audio I've imported from FCP show up as A1 & A2 (for example) on one track so that I can edit them at once and hear how the effect sounds when applied to both? It's just dialogue so I don't need stereo separation. The doorbell sound effect I'm using from STP shows as A5 & A6 in STP and in FCP it looks just like the other audio tracks (a linked stereo pair).
Background;
Some of the audio was recorded on one camera using a boom mic going into input one on the camera. So it was mono and I copied and pasted it to track 2 in FCP and linked it to make it a stereo pair.
The remaining audio was recorded on another camera using the on-camera stereo mic so it came into FCP as a stereo pair from the start.
Any help would be greatly appreciated.

I have Soundtrack and was wondering much the same thing. From your discussion it appeared that one could not split a stereo track into the two mono tracks and then work on each separately. However, upon reading the Help manual for Soundtrack 1.5 at page 167, it explains how one may export a stereo track as two mono tracks as follows:
To export individual tracks, busses, or outputs:
1 In the Timeline, select the tracks, busses, or outputs you want to export, then choose
File > Export > Export Selected [item].
The [item] shown in the menu changes depending on whether tracks, busses, or
outputs are selected.
If nothing is selected, each unmuted track, bus, and output in the project is exported as
an individual AIFF file.
2 In the Export dialog, choose the sample rate for the exported files from the Sample
Rate pop-up menu.
3 Choose the bit depth for the exported files from the Bit Depth pop-up menu.
4 Optionally, select the “Output dual mono files” checkbox to export the selected tracks,
busses, and outputs as dual mono files, then click Save.
5 Browse to the location where you want to save the exported files.
6 Click Export.
Each selected track, bus, or output is exported as a single stereo AIFF file or as a pair of
dual mono AIFF files. Muted and unselected tracks, busses, or outputs are not exported.
This might solve your problem because you can then import those two tracks back into soundtrack and work on them separately.
It worked for me.

Wierd Audio Behavior suddenly, stereo tracks now take up 2 mono tracks?????

So I start a new file, or open an existing file and all my tracks that have setero information all of a sudden take up 2 channels on the mixer, so if the audio is on track 1, meters for track 1 and 2 move. If I make track 1 a stereo track, track 2 disappears and says "Controlled by Stereo object "track 1-2""....now all my routing is messed up as this effects busses and everything...what gives? Is there something in my preferences that got changed? HELP!!!!!!!!

What the heck, tbird? Are you able to bend the parameters of time now, too? There was no post here when I replied with mine. Please, do share your secrets!

Compressors with Stereo tracks

I've been recording solo steel string guitar with 2 mics and panning one to the left and other to the right. I think I've sorted out most of the phase issues this brought up with some better mic placement.
Once recorded the levels of each track peak at about -14 or -15.
the song is a fingerstyle tunes with lots of dynamic changes.
I've been messing around trying to smooth a bit of the peaks and bring up the overall levels with the "Silver Compressor". Now the loudest peaks are about 5.8 to 6.9. I have a Silver Compressor on each of the 2 guitar tracks with the same settings....
attack 3.5ms
release 98.0ms
threshold -17.5
The result is the gain meter on the compressors going to about -5 pt -10db and overall more percieved loudness.
I like it
Question 1. How do those compressor settings sound to you all?
Question 2. What issues do I have with the fact that I'm using an individual compressor on each of the 2 guitar tracks? Something tells me there might be a better way.
Question 3. I've been using the Silver Compressor because I find it easier to use than the regular Logic Compressor. I'm just not sure what all the controls do on that compressor. Any thoughts on if I should try using the regular compressor rather than the Silver?
Question 4. Sometimes I play around with the Mastering Channel Strip Settings on the Output 1-2 track including the preset multiband compressor. Any thoughts on how that might be used on the solo guitar song?
Thanks for all your help and ideas in advance...
Morris

Q1: If you like it, then our opinions matter very little.
Q2: No issues, really. Maybe if you had lots more tracks going on with lots more plugins runnning you might want to consider sending stuff into the busses and effecting/compressing them that way. Or, you could set up to record your X/Y mic'd guitar onto a single stereo track and add a stereo compressor of your choosing. It would simplify things, which is usually a plus, because you'd just have to adjust one compressor plugin.
If this is what you are doing (your question is a little ambiguous), then maybe experimentation is in order, perhaps recording the L and R to two separate tracks and compressing them diferently would be a nice effect that serves your purposes better, hard to say. But it seems kinda self-indulgent and potentially distracting LOL.
Q3: Maybe read this: http://www.recordingproject.com/articles/article-printable.php?article=6 for a nice guide with audio examples. Or http://www.saecollege.de/reference_material/pages/Compression.htm
Q4: I usually slap some sort of multiband on the Output 1-2 for mixdown. I do not mix with it on. I use it to tighten things up at the end--but I do not rule out doing more level adjustments on the other tracks with it on

How to route the L and R signal of a stereo track to different auxes.

Hi there,
I'm wondering if there is an easy way to route the L and R signal of a stereo track to different busses independently?
I used a workaround with split-stereo files but there must be another way of routing the signals.
Any idea?
Thanks Eddie

How to create 5.1 from stereo tracks

So here's the instructions I was able to find to use Waves UM plugin, which creates 5.1 surround output from a standard stereo track in Logic:
1. Place your stereo file on a stereo track.
2. Assign its output to the surround output or bus as required.
3. From the Insert menu, choose UM226.
*Please note that Logic must be set to Universal Track Mode - On
The problem is, this is my very first project in Logic, and I have no idea how to do step 2. Can someone give a total n00b a step by step?
Thanks.

Here's a quick and dirty way to surroundize a mix, but you have to be careful and monitor it properly and check for stereo/mono compatibility since that's how lots of people will hear it.
Take your stereo mix and change the panner to a 5.1 panner.
Change the panning so that some center channel gets filled in like so
!http://www.rdiv.com/screenshots/STP_51pannerFront.jpg!
Then add a buss with a (let's say) Platinum reverb. Add a send to your stereo channel that feeds this buss. You should have a setup something like this.
!http://www.rdiv.com/screenshots/STP_surroundized.jpg!
Change the buss panner to 5.1 and shift it to the rear a bit.
!http://www.rdiv.com/screenshots/STP_51pannerRear.jpg!
Oh did I add that you need to monitor this properly and check for how it will downmix back to stereo and mono? Keep the reverb tasteful and short decay so that it doesn't make them sound like there in the bowels of the titanic.
There's also the better way to do it, with [TC Unwrap|http://www.sweetwater.com/store/detail/UnwrapP>, however it's only available for Protools TDM or PowerCore.

Surround Sound from stereo tracks

I was under the impression that you could mix Surround right on the FCP track in FCP 6. IF you can I dont see it.
My files are Wav files
I have one stereo track for audio (two tracks).
One stereo Music
One stereo Effects
I want to put the narration on the center speaker and
the music on R L and also the rear R and Rear L
and the effects on the Front R and Front L.
Do I have to go into SoundTracks to do this or is there a way to do it in FCP6?

I was under the impression that you could mix Surround right on the FCP track in FCP 6. IF you can I dont see it.
In your Sequence Settings, alter your audio preset to 5.1, you'll then get 6 outputs/busses - 1 stereo pair (for L & R) , 1 dual mono set (for C & LFE) and 1 stereo pair (for L & R Surround).
You can then 'mix' within FCP by sending the tracks in your timeline to the specific outputs. Though in your case, since you have pre-mixed elements, this might not work for you.
But, as Jerry says, you're best off with a dedicated 5.1 setup. Otherwise FCP automatically does a stereo downconvert for monitoring

How to capture 2 stereo tracks (4 channels) in Premiere CS6? Thanks!

Problem capturing 2 stereo tracks (4 channels) into Premiere CS6 (on a Mac) from a Canon xls1? Thanks, IndigoJim!

I'm sure I used to get all 4 tracks from my XL1s, If I rememder correctly there was one Avi with a stereo track and a separate wav with the other pair. When in 4 track mode the audio is only 12 bit. The computer I used back then had a Matrox RT100 board, It might have been a Matrox utility that I used for the capture.

How do you combine 2 mono tracks into a single stereo track?

Question here:
How do I combine 2 mono tracks into a single stereo track in Logic?
I recorded using my left and right out of my keyboard to a hard-disk recorder (Korg d888). The files are made as two separate wav files. Is there way to combine these in Logic so I can treat it as one stereo track?
I have several files to do and am hoping Logic has something like a "combine tracks to stereo track" tool or something.

Solo both tracks and bounce them with no effects and faders at 0 dB.

How can I extract the two channels from a stereo track?

Hi,
I am writing a class that is able to draw an audio signal. It seems to be working well but I have a question. If I load a mono audio file I am able to draw it on a graph by using the byte[] array and everything is ok until now. That's the code:
void Draw(byte[] x)
            Graphics g=getGraphics();
            Graphics2D g2=(Graphics2D)g;
            g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,                     RenderingHints.VALUE_ANTIALIAS_ON);
            for(int i=0; i<x.length-6; i++)
                g2.draw(new Line2D.Float(((i*(getWidth()-6))/x.length)+5, (getHeight()/2)-          ((x*(getWidth()-6))/x.length), (((i+1)*(getWidth()-6))/x.length)+5, (getHeight()/2)-     ((x[i+1]*(getWidth()-6))/x.length)));
The results is correct only if I have a mono track. Obviously when I get a stereo track the array becomes very large so here the question. How can I extract the two audio channels from a stereo track?
Thanks in advance.
Maurizio Di Vitto

A mono audio stream is stored [sample, sample, sample, sample], so just a list of samples in an array.
A stereo sample is interleaved in the same manner, so you get [left-sample, right-sample, left-sample, right-sample]
So every nth sample is the 1st channel, every nth+1 is the 2nd channel...

In Final Cut Pro X 10.1.1 I'm trying to separate left and right stereo tracks to delete left and pan right to centre. I cannot find a way to do this.

I record in stereo with a 10KHz tone down the left channel to defeat AGC on my camera and mic feed into the right channel. When I edit, I want to mute/delete the left channel and pan the right into the centre, to leave me with mono audio across both left and right. I could do this easily in FCP 6 but can find no way to do it in FCP X. I'm using the same source files. When I choose Dual Mono mode in the Audio Inspector, it mixes left and right and pushes the combined signal into both channels, giving me a mix of 10KHZ tone and audio in both left and right. Stereo mode shows me the two channels correctly with one driven hard (the tone) and the other at good voice levels. I just want to kill the left channel and pan the right to centre.
I'm converting original TOD files using MPEG Streamclip before import and definitely keeping audio as stereo.
This is driving me nuts! It should be simple and is in FCP 6. Any help greatly appreciated.
Stereo Setting
Mono Setting

Mb - If you're using FCPX 10.1.1 and Mavericks, make certain you've downloaded the most current Sony XDCAM FCPX plugin from sonycreativesortware.com unless you're using an older version of FCPX and then you'd need the previous XDCAM plugin.
You shouldn't see 8 mono tracks. There are import settings in /fCPX that you can check and I don't ask FCPX to analyze my media or seperate mono or combine stereo, etc. I like to have everything come in as it is, especially because I know what I've done with every channel, etc.
What I wrote to Ian is what I'd tell you - so please take a look at how you can make a "stereo" track that is actually two mono tracks, mono. Once you do that you can address each mono channel by itself since it needs different volume, compression, and EQ than other channels.
There are ethernet, USB, and firewire controllers that work in FCPX, but that's not the typical workflow because generally if you're getting into any amount of post audio sweetening beyond basic "staples" audio treatment, you would instead use "Roles" to export your audio to Logic or Pro Tools and do you work in those applications and then cut the final product back into your FCPX project. In Logic or Pro Tools is where you might use a controller.
In terms of automating levels, I'm not positive I know what you mean. Compressor is a nice internal Logic plugin that kind of automates levels in a way but its about compressing peaks at a threshold that you set and at a ratio of compression. So I may not understand what other automation is available unless you've exported you tracks to Logic or Pro Tools.

Export mixdown of several stereo tracks as one mono track

How can I select a few stereo tracks in STP and export them as a single mono track? either back to FCP or as a standalone file?
Thanks!

Oops, i posted this in the wrong discussion group. can this be moved to STP?

On the Channels Strip (of the Audio Track with the Audio Region), ctr+click on the left segment of the Input Button. That opens a popup menu where you can select Left (only the left channel of the Audio Region is played as mono), or Right (only the right channel of the Audio Region is played as mono).
Once the signal flow of the Channel Strip is mono (one channel), you can use the "Mono➤Stereo" version of some plugins to convert the Channel Strip to a stereo channel.
About your second question. If you are referring to the little blue "Catch Playhead Button", that automatically scrolls the Workspace when the Playhead reaches the right border to keep the Workspace visible. You also can also enable the "Scroll in Play" mode in the local View Menu. That one locks the Playhead in the center and scroll the Workspace "underneath"
However if you are referring to that little Play icon in the left upper corner of the Region Header (only visible in the Editor), that one, the "Solo Play Button", only plays that Region in solo mode. It is basically a combination of "Play " and "Solo" in on button. You can find all those little informations and much more in my graphically enhanced manual "Logic Pro X - How it Works".
Hope that helps

Soundtrack pro can't export stereo tracks

Ok. I have a problem. I'm recording some stereo cassettes into logic, then cleaning them up in Soundtrack. the editing flow is very usable. now, when I want to save, I have very limited options. Why can't I save as mp3/m4a/etc?? I see that export is what I need. Oh whoops, you can't export from a stereo track. Why?!!!?? Ok, so how do you convert a stereo track to multitrack to export? I could pretty much move completely over from Audition if I could figure this out. Help? I can't be the only one editing stereo masters in STP?

ok, how can I import stereo into two mono tracks? can files be moved from edit mode stereo into multitrack?

Changing 2 Mono Tracks back to 1 Stereo Track on timeline, or source monitor?

I was working in Premiere Pro CS 5.5 and I switched Audio on a clip to 2 Mono Tracks instead of its original 1 stereo track. I brought it in the Source Monitor and then on the timeline.
I then realized later on that I wanted to switch the audio back to 1 Stereo Track instead of the 2 Mono tracks.
I could not figure out a way to do this.
Is it possile to do this? If so. how?
Thanks in advance?

Joe has given you a good answer, but exactly why do you want to switch the two mono Tracks back to Stereo?
If one is not doing certain things, then they will be Mixed-down to stereo on Export. However, certain editin operations WILL be easier with both back in stereo, if you are doing those.
Good luck,
Hunt
