[Rwp] Time stretching

Tue Sep 15 09:47:43 EDT 2015

Hi Chris, thanks for having a play with that. Initially when I posted this topic, I assumed that the reason I wasn't getting this to work was either because I was blind, stupid, or maybe both. However, I've posted this issue on the Reaper forum and someone has confirmed that this is also how it works for sighted people. Apparently, it is a requested feature that Ripple status influences time stretching behaviour, but seemingly this is not the case at present. I have never posted a feature request, but there's probably a place on the forum. Incidentally, the chap who responded to my time stretching query was very good at providing a non-mouse-based description of time stretching items. While the solution didn't remedy this issue, it was gratifying to observe this interaction, and that regular sighted Reaper users are able to help us blindies by suggesting action-based responses, rather than "just drag the mouse over the wave form" type responses.

I'll give your work-around a go later today, but I think that's the best we're going to get for now, and hopefully Reaper will allow the ripple mode to influence this behaviour in the future.

Thanks.

If I slow the item, then the item will not play in full, because the next item will interupt it. I cannot see the logic in this system. If I want to time stretch some audio, chances are that I might want to actually time stretch all of that audio, not just the amount of audio that'll fit before the next item interupts it. There doesn't seem to be a way of time stretching a selection, unless I'm missing something. I also tried creating a region, thinking that maybe I could time stretch a region, but I can't seem to find such an option. I can try posting this in the Reaper forum, and see what happens. I'm surprised that more people aren't finding this a problem. Perhaps it's easy to do with a mouse, and time stretching items just isn't the answer. But I can't see any other way of applying time stretches other than to items. I have trawled the Internet, I have prayed to the gods - all of them, just to be safe - but alas, nothing!

In Reaper  and Pro Tools you will have to use Ripple or  Shuffle mode respectively to have the audio move to the left and fill in th   gap of whatever got cut. You can Assign the different ripple modes to keyboard hot keys so you can quickly toggle between them on the fly. Also Reaper has a Remove items moving later content which does the same as one of the ripple mode.  Experiment with Chaining that next to a  other actions for selections  and you may find an even faster workflow.  Others using Sonar 8.5.3 is still an option lol.

I understand intellectually what is happening and why it's happening, but I assumed there would be an option when stretching to have the next item move to the left a bit in order to facilitate a smooth transition, and so that your time stretched audio seamlessly intigrates with the rest of the audio, without silence. If there was a way of doing the time stretch with the item glued, unticking the loop option so that you have the silence, and then having an option to somehow trim that residual audio, then that would be great. If this is what you are talking about, then I apologise for my slowness. However, I think you are suggesting that I do the time stretch, then manually select the audio I want to keep and then do the trim thing. This obviously would work to a degree, but it just seems like doing the same thing twice, and there is room for error, in that I'd have to make an accurate selection. Similarly, I could achieve the same result by just selecting the audio I don't want and deleting it with ripple on. If the residual audio from the time stretch split into a seperate item, then I could simly delete that item. That would make sense to me. I just think Reaper must have a better way of doing this that I'm missing. Failing that, then I'm just going to have to try and experiment using your suggestion. But Sonar didn't have this issue. You made your time stretch, and that portion of audio was altered, and the rest of the audio on that track moved left or right to accomidate it. Thanks.

Which is why if you had loop checked it repeated it self because it looped to fill the space that would of been empty. If you don’t have loop check it has empty space cuz the item still has blank room there there was once audio. By trimming the iTem you tell it to make the length of the item the new size that just have audio instead of the original length.

I would have thought that it would be logical that people would want to select a piece of audio, time stretch it, and have the rest of that audio play immediately afterwards. It seems strange that this seems like an impossibility to achieve, given that Reaper's philosophy appears to be that you can optomise and modify pretty much everything. Every tutorial on the Internet about time stretching talks about dragging the mouse over the portion of audio. There has to be a way. When I used Reaper on the Mac, I remember thinking how time stretching was the easiest I'd ever experienced. Better than Sonar or ProTools. However, I think I might have been selecting a portion of audio and changing the tempo for that selection. I certainly wasn't using items, as that didn't seem doable on the Mac. Oowever, if I did change the tempo, then this would affect the entire project, and not just !

I make a selection and then split that selection to create an item. I select the item I'd like to time stretch. I press shift F2 to open media item properties. I set the rate to 2 then press enter. The item now plays twice as fast, which is great, however the length of that item is still the same, so I now get more audio than I'd like. to try and fix this I glued that item. This time changing the item speed looped the item twice. I'd fixed the residual audio problem but now got a different problem as a reward for my efforts. Still feeling optimistic, I went back into media item properties, and found a loop option that was checked. I unchecked it, changed the rate to 2, pressed enter, and held my breath, ready to proclaim myself a genius for having remedied the issue. The item played twice as fast, which is great, but then there!

I tried experimenting with toggling ripple on and off, but nothing would work. So I had a little swear at my computer - it doesn't mind, it's used to it - and decided to email you good people in the hope that someone might be able to help with this irksome little problem.
