Converting item volume to track volume

[ludwigmueller]

Hello all,

I have countless items on a track. I have adjusted the volume of every item seperately, but now I would like to transfer those volume changes to the track volume automation lane. Is this possible somehow?

Best,
Ludwig

[Fergler]

Don't think there is a way, someone could make a script I guess. My question is, why?

What does this enable you to do?

[spk77]

This is *not possible via scripting at the moment, but will be.
(I think it's already possible with the latest pre-version of Reaper/ReaScript)


*not possible = very difficult

[Goldreap]

You could just glue all the items, then all your per item volumes are accounted for in your new glued item. But perhaps you wish to keep all your seperate items?

[ludwigmueller]

A script would be wonderful. The reason: its a voice over track in a movie on which I adjusted every item via item volume. But on the track itself I have to put a certain effect which needs to be hit by every item at its original volume. However, I don't want to loose the volume levels, so a script to transfer the item gain to track volume automation would be incredibly helpful. Next time I'll use the pre-fx-volume automation, but the volume-per-item method is just so much faster :-P

Meanwhile: Is there a script or function to reset the item volume of multiple clips at once?
Edit: Hang on, found it in the SWS extensions!

[Quest The Wordsmith]

Since you found the SWS function to reset all the item volumes, I would take this course of action:

1. Duplicate the track
2. Remove the item volumes on duplicated track
3. Put FX on duplicated track
4. Set FX to 100% wet

Now you have the original volumes hitting your FX and still maintain all the item volume work you did.

Something like this will be possible :
("Reset item volumes" would be easy to add to this script)

Found this thread, is there a working solution now? I really need it.

Hi Tim, I didn't realise this was a very old thread until I saw your post.

At anyrate, I was going to tell him all he had to do was duplicate the track, remove all the take volume envelopes, then EQ that track.

Then when he's done he can tranfer the EQ to the other track that has the take volume envelopes.

[daniellumertz]

The Volume envelope needs to be already ON on the tracks or this script will fail.

function Main()
  sel_item_count = reaper.CountSelectedMediaItems( 0 )
  
      for i = 0, sel_item_count - 1 do
      
        sel_item = reaper.GetSelectedMediaItem( 0, i )
         
        sel_item_vol = reaper.GetMediaItemInfo_Value( sel_item, "D_VOL"  )--volume
        
        sel_item_time = reaper.GetMediaItemInfo_Value( sel_item, "D_POSITION"  )--time
        
        sel_track = reaper.GetMediaItemInfo_Value( sel_item, "P_TRACK"  ) -- track
        
        env_name = reaper.GetTrackEnvelopeByName( sel_track, "Volume" )
        
        reaper.InsertEnvelopePoint( env_name, sel_item_time, sel_item_vol, 1, 0, false )
        
        reaper.SetMediaItemInfo_Value( sel_item, "D_VOL", 1 ) 
      end

end

reaper.Undo_BeginBlock()
Main()
reaper.Undo_EndBlock( "Script Item Vol to Envelope", 0 )

Also I started to make scripts like this quarantine, so I may missed somethings hahaha

This looks good, thanks..

I wonder, is it possible at all to script something whereby Track Volume Automation is "moved" to the Items on the track as Take Volume Automation?

[daniellumertz]

Hi MPL!! Thanks for the code! I will analyse the changes in it, always good for learning heheh! I'm a little busy in a project right know, else I would see it already. Thanks

[pepe44]

Thinking about this, is there a way we can "copy/ paste" fader volume to send volume?

This would be very handy to make cue mixes using the mixer faders rough mix to heaphones for example.

It should be easy to make an script for that. I'm in the middle of a rush in a project else I would try....

[Alexis Baskind]

Dear all,

daniellumertz, mpl, thanks a lot for the scripts, this is very useful. Below is a suggestion that does two slight modifications:
1/ adds an envelope point after the item
2/ if not only the item volume but also the take volume has been modified, applies a track volume which is the product of both (assuming the current take for each item).

Best

[daniellumertz]

nice Alex ! thanks for sharing always nice to see changes

don't forget to put the code in the forum with [code] and '['/code] (don't actually put the ')

 Like this

[anomar]

Thanks
daniellumertz, mpl, alexis. Script works great.

One question.
Is it possible tha instead of a VolEnv the final result be a Pre-FX envelope?
I've asked because Item Volume is Pre-FX, (or am I wrong ?) and sometimes it would be more useful.
I try to do this combining this script with other actions but I think a little
cumbersome.

Thanks again.

[Alexis Baskind]

Hi anomar,

I haven't tested it, but I guess that if you replace "Volume" by "Volume (Pre-FX)" in all lines containing "GetTrackEnvelopeByName", this should work.

Alexis

[anomar]

I know nothing about scripting, but I think I can do that.
Thanks Alexis.

Hi Alexis,
worked ! I also changed action 40406 to 40408
Thank you all.

My items are overlapping, how does it handle items that have crossfades and volume automation?
I am asking, because it results here only with points, none of which follow the item automation.
