Default How to split a single track into multiple files

Hello,

I've seen this question posted before but I've yet to find a good clear answer to the problem. Maybe I just missed it, because I do believe I figured this out once some time ago but now I can't find the solution.

It comes up a lot. Say you have a long single stereo track of a live performance and you want to break it up into individual songs. You can do so with markers. Maybe you added some compression or EQ to that long track of multiple songs. It's all one live recording so the effects you added work for each song.

How do you most simply then render that down to multiple .wav files? So that each song at each marker becomes its own separate wav file.

Thank you to anyone who has a clean simple approach.

I don't know all the fancy shortcuts, but I know that you can double click between markers to select that section, then right-click and create a region from the selection, and then in the render dialog choose "project regions".

Hello Rubwrongways and welcome to these forums. You'll find many helpful people here and a lot of useful information.

It all depends. You might:
-- Split the single long clip at the desired points,
-- Glue each clip to "re-render" it,
-- Duplicate the track several times,
-- Remove all but one of the clips from each track.

That way you end up with each song on its own track with its own instances of the FX, for individual tweaking.

Or,
-- Split the single long clip at the desired points,
-- Glue each clip to "re-render" it,
-- drag each clip to a new track,
-- route that track back to the original track.

That way you end up with each song on its own track, routed to a common FX track, for tweaking.

Default Thank you.

Thank you, DarkStar and ashcat_It. These are both great suggestions.

Normally my approach is to just do what it takes to make it work and get it done with but I know this is going to pop up a lot for me so I'm really trying to find the best way.

DarkStar, while your option will certainly work, and it's what I'll do if I find no more automated way, I still have this nagging suspicion that there is a way to break up these individual sections into their own .wav files automatically.

ascat, I'm not quite sure how to do what you are saying. When I double click in between markers, I get the Media Item Properties Window. If I single click to just select the section, I can't see how to create a region from right-clicking. Also, if I did do that, would the "project regions" render split each section into its own file?

Thanks!

Not sure I understand what exactly you are trying to do but...

Slice/cut somewhere BEFORE the song starts

Slice/cut somewhere AFTER the song ends

Select Track (click on track between slices)

Copy (CTRL-C)

Open New Project TAB

Paste (CTRL-V)

Thanks Jeffsounds,

I've attached a picture here, if that helps.

http://forum.cockos.com/attachment.p...1&d=1396619828

I want to render this thing one time and have it create a number files. I'd like each section (song) to become a .wav file automatically.

I know I can just take each song separately and render it on its own but it seems that there is a way to hit the render button once and have the computer split all those songs up at their markers and create new individual .wav files for each.

I'm pretty sure I've done it before. But it was a long time ago.

use regions instead of markers. create one region for each song and name it accordingly.
go to the render menu and select to render all regions (you can enable/disable single regions via the region manager).
in the filename field you can make use of the wildcards ($region will name each rendered audio file after the corresponding region).

EDIT: you can let reaper create a region for each selected item automatically via the action Markers: Insert seperate regions for each selected item

Nope, splitting a clip in Reaper is non-destructive.

All of the clicking that I talked about has to happen up above to timeline/ruler whatever, in that area where the markers are. Not on the media items themselves. Once you find the right-click menus,maybe make a note of the keyboard shortcut.

Thank you, everyone. I'll try the region approach. I will make sure to report back here so that anyone else seeking a similar solution will see it.

Where' Viente? Sounds like an easy ReaScript that would be faster than the native method.

1. Split that clip at every marker.
2. Parse the number of items (splits) as "i"
3. Run a loop... For each i, select it and bounce it to a new track with fx, stereo mute original

That would result in Darkstar's stair stepped renders.

ashcat_it - your region solution worked perfectly thank you.

Lawrence, what you wrote makes sense but I'm afraid it is just a bit beyond me computer-wise.

Thanks, everyone!
