Time Shift +350msec

Select one track of a multiple track collection and Time Shift it forward by 350 mSec. (as an example). Accurately without dragging.

This should be easy to code, the details of GUI need consideration. Since it is a Track-related process, I am thinking – add an item to the Track’s twisty/drop-down menu which pops up a requester dialog asking “How much?” and gets user input with a Time Text Control (TimeTextCtrl–one of those timer selection widgets like “Selection Start” in the Selection toolbar).

As for moving the track’s audio’s start, I’m thinking just add that much silence to the start of the track.

But, now that I am playing around with this, why not just move the cursor to Start of Track and generate as much silence as you want to time shift by?

No reason at all. I’m thinking of a specific condition where a careful, timed match-up of two tracks is performed and then you have to apply that time correction to multiple tracks.

Measuring the carefully hand-generated gap and Generate Silence to that measurement would work perfectly.

Two existing possibilities:

  1. There is a Nyquist plugin called Time Shifter that inserts a specified amount of silence in front of the track. It even lets you move L and R channels of a stereo track separately.
  2. The way I usually do is to type in the Selection Start time in the Selection Toolbar at the bottom, then Align the track with the Selection Start. That lets you align it forward or backward…

In fact I thought about doing that and couldn’t get it to work. What are the strokes exactly?

Make sure you set the time scale in Selection Start to hh:mm:ss + milliseconds.
Select the track you want to move, and type in the time point you want. The beginning of the selection will automatically move to this time point.
In this example, I’ve chosen the 3rd track and set the Selection Start to 350 ms:

Then from the Tracks menu, choose Tracks>Align Tracks>Align with Selection Start. The beginning of the 3rd track will move to 350ms exactly.

That’s it!

I propose to move this to the Audio Processing section as solanus has provided a method to do this with existing Audacity.

@Koz: do you still want me to add this to the Wiki>Pending Feature Requests page - or is solanus’ solution good enough for you?

@Koz - BUMP

I don’t see much point in having this as a feature request as there are already a couple of ways to accomplish the task.
Namely, generating silence at the beginning of the track, or using the “Tracks > Align Tracks”.
The second of these methods appears to be specifically for the functionality that Koz requested.
