Render items as .wav with embedded loop points?

[IXix]

I assumed this would be possible but I can't see how to do it.

I'd like to set up a bunch of items, drop markers/regions where I want the wav loop points to be and then render the items as wavs with the loop points embedded. Is that possible?

As far as I know, loop points cannot be embedded into audio files in Reaper. But you can embed regions and markers into the files while rendering. Other audio editing programs like Wavosaur will recognize these markers, so once in there, you could use these markers to help create the actual loop points which can then be saved into the file.

Back in Reaper, those loop points will show up as cues which can also be imported back to the project as markers. But depending on what needs to be done with the looped files, this workflow will get unnecessarily convoluted.

Ah okay, thanks. That's a shame because Reaper is great for finding loops.

xpander's answer is correct but it seems like it's being interpreted as a no rather than a yes. There is a dropdown box in the WAV render settings where you can choose to embed regions in the file as pairs of cue points. Other software can interpret those cue pairs as loop points.

Thanks schwa, I got that. Just disappointed that it will require extra software. Whenever I wonder if REAPER can do a thing, the answer is pretty much always yes.



Don't suppose you fancy implementing it as a feature?

What is it you want to do? Import a WAV with embedded loop points, and have the loop automatically set on importing the WAV? Here is a Lua script that will do that:

item=reaper.GetSelectedMediaItem(0,0)
initpos=reaper.GetMediaItemInfo_Value(item,"D_POSITION")
reaper.SetEditCurPos(initpos,true,false)
reaper.Main_OnCommand(40741,0) -- cursor to next embedded cue
spos=reaper.GetCursorPosition()
reaper.Main_OnCommand(40741,0)
epos=reaper.GetCursorPosition()
reaper.GetSet_LoopTimeRange(true,true,spos,epos,false)

Thanks, that's a useful little script to have but no. I've got fifty samples of an instrument that would benefit from having loops embedded for note sustain purposes in a sampler. I'm looking for the least tedious way of doing it!


Having just tried it with a single file though, it looks like REAPER's cue embedding will be enough. Both the sampler and Wavosaur treated the cues as the loop, so no extra software required! Just another forty nine to go!
