It seems like possible to make a track go slower without lengthening it .. someting with grains I would think ..

Are there tools that can do such a things .. or am I dreaming?

I'm pretty sure that's not possible, as if it is slower it must take longer, unless you somehow remove parts to make it shorter!

What did you want to achieve, in case that helps me think of something?

I was .. well when it was just one thing and played .. or automated .. it could be done anew and slower .. but I had a mix of recorded sounds that I wanted to be slower .. and that would be a lot of work.

The drawback of "tape editing" .. ultimately flexible in what you can do .. but not so much in what you can undo .. unless you back up every detail .. which I did not .. basically because that results in lots of audio files. And it would still be a lot of work to redo everything.

I wanted a lazy way out .. and in the end just accepted how it was .. which was a lazy way out .. of course :)

My idea maybe was to take tiny snapshots of a track .. then leave out .. say half of them .. and then slow those left over down so they get twice as long .. and then glue them back together.

And then maybe when that is not in sync with the "beat" oe whatever sequence of events.

Hmm i think i could actually try that ... in a different way/order .. but .. I do have a VST that can make holes in a track .. then I can stretch the track .. and finally remove the silence .. which my wave editor can do automaticly.

I'll have to keep this unread .. to keep it out of my head .. in my head ..

[ As .. now busy with some other things .. hero wouters and bianca holst seem to have a lot of nice stuff : https://www.youtube.com/@herowouters/videos .. I was looking for "overbodige muziek" (superfluous music) :) ]

Hmm .. ok . .we go from start trough mid to finish ...

it works not very well Cool

i had to cheat a bit . .silence removal did not work well .. it cut it down to 20% or so instead of 50%

edit: still it sort of .. may begin .. to illustrate .. an onset .. to what -- maybe .. could be achieved Laughing

I tried some other settings and things .. very very fiddly Shocked

edit2 : the chop frequency matters a lot .. this was dome at 17Hz ``(and with a duty cycle of 50%) . when it is too fast it will just detoriate quality.

This is a really interesting idea/ concept

The final sound reminds me of what you get from Paulstretch, it's probably a similar approach to do extreme time stretching, but that adds extra bits rather than takes them away

Hah, that then is why I downloaded Paulstretch today Laughing

As it turns out it can not only lengthen but shorten things as well .. so I've tried to shorten the start file by a factor two .. into mid 02

And then stretched mid 02 with the regular wave editor tools by a factor of 2 into finish 2

Not what I had intended either .. but it sounds nice Cool

PS kills most of the timed events already in mid 02; but Paulstretch has tons of options to experiment with .. did not do that as of now.

BTW .. I used PaulXstretch from sonosaurus :: https://sonosaurus.com/paulxstretch/ [I used the mac version, but it seems to run on a lot of stuff].

It's funny actually as I have a vague memory of wanting to use Paulstretch to shrink a long piece into a short one just for fun, but I don't think I ever got round to it, maybe I should give it a go Laughing

It's quite a destructive process isn't it!!
