Tracks question

[Justafingerpicker]

On a stereo project, there is sound on the existing left track does not exist on the right trick. I can figure out how to duplicate the sound, but the how do I then merge that duplication with the existing right track, without erasing what it already contained?

In Audacity 1.3, you can Tracks > Add New Tracks and copy-paste the work into the new track. then use the Time Shift Tools (left and right arrow) to push the new work into alignment. All the tracks will play at once unless you prevent them.

You can use the balance adjusters to the left of the track to force the work onto Left or Right or any combination.

You can use the Envelope tool (two white arrows and bent blue line) to graphically change the volume of any of the selections to balance the performance. The tracks will mix to a single track on export, or you can Mix and Render to provide one stereo track with all your corrections in it.

The "Channel Mixer" plug-in may provide what you need: http://forum.audacityteam.org/viewtopic ... 39&t=33563

I guess I don't understand this as well as I thought I did, because I couldn't get it done last night. I selected the opening riff from the Left track, did a control-D duplicate which appeared below the Right track (with which I wanted to merge the duplicate.) I selected both the Right track, and the duplicate, and clicked on Make Stereo Track. I then exported the project as a Wav to test...and when I re-opened that test Wave, all it had was the Right Track (now showing as the Left) and the Riff-only showing as Right.

Do I need to do a Merge and Render in there somewhere? The objective was to combine the original Right track with the duplicate and for that to become the new Right track of a stereo wave, so that the file consisted of the original Left track, and the newly-merged Right.

I selected ... from the Left track,
.. Ctrl+D duplicate which appeared below the Right track (with which I wanted to merge the duplicate.)
I selected both the Right track, and the duplicate, and clicked on Make Stereo Track.

"Make Stereo Track" just "glues" the two tracks together.
The upper track (from where "Make Stereo Track" was selected) becomes the Left channel
and the track immediately below it becomes the Right channel.

To see this work - open a new project and create two mono tracks.
From the Generate menu, generate a tone in one of the tracks.
Now, from the upper track, click on the track name and in the drop down menu and select "Make Stereo Track".
Is it now obvious what is happening?

The objective was to combine the original Right track with the duplicate and for that to become the new Right track of a stereo wave, so that the file consisted of the original Left track, and the newly-merged Right.

Just to check I've got it right - you want to:

1) Duplicate the original Left Track
2) Combine this duplicate with the original Right track
3) Glue the original Left track to the NEW (mixed) Right track
Result = Original Left on Left Track / Original Left + Original Right on Right track.

How to do it:
1) "Split Stereo to Mono" (from the track drop down menu. - creates 2 mono tracks
2) Duplicate the upper track (original Left channel) - Duplicate is a mono track below the other two (track 3)
3) Select track 2 (original Right) and track 3 (Duplicate Left) and then select "Mix and Render" from the "Tracks" menu. - this "combines" (mixes) the duplicate with the original Right channel.
4) On the upper track (still the original Left channel), select "Make Stereo Track".
5) Play the track to check it.

Alternatively, using the "Channel Mixer" effect, just select:

Preset: Use Custom
New Left Channel:
Left Mix > 100%
Right Mix > 0%

New Right Channel:
Left Mix > 100%
Right Mix > 100%

This worked absolutely spot-on perfectly. Thanks for the detail.
