Hi
Recently, some amazing samplers with slicing ability were made available for free. Like ShortCircuit2, for example, which can read the Rex files or audio files sliced according to markers.

It could/would be great if Wavosaur could :

- automaticaly slice a file in 8/16/32/64 slices of the same size ;

- and/or automaticall detect transients and create a marker at each transient peak, so that these markers would be read as aslice by the sampler.


I hope you'll find the idea usefull !

Hi!

I think your idea interesting.
Could you explain me:
- what is slicing for you: just add marker or exporting N wav files.

If you speak french, please explain us your demand in the french part.

Hi
Slicing in that case is just adding markers that the sampler will understand as a new slice. No need (for me, at last) for exporting N slices (even if i see very well the kind of use it could be with long recording sessions with multiple songs on a single audio file )
I'll consider posting into the fr forum.
Cheers

Ok I understand.
It's yet possible to do this operation with 9000 version:

To show grid lines:

Options->Selection grid lines

To change grid line number:

Options->Editor configuration & Selection grid line number = N

Ctrl+A (select all the sound file)

Tools->Markers->Set Markers as grid lines

But it's possible to add a direct function to do this.


For transient dectection, could you send us a picture (example) with what you want?

Oh, it is cool : if it is already here in an indirect way that is fine : making it direct should be easier, i guess :)

- Yes, a direct way to do it would be the best : a dialog box where you can type the number of equal slices you wish ;

- About auto-transient detection, i am thinking about it the way LiveSlice does it (or Reaper, but Reaper doesn't drop slice markers, it actually slices one single clip into multiple clips).
Here is a preview of what i am thinking about :




..; and in LiveSlice

Ok, thanks!

For slice number, it's not difficult to add a dialog box to have direct way to do this.

I understand the automatic transient detection. I don't know if it's possible to add this feature for the next release, but we will work on it!

Super !
Merci beaucoup :)
J'imagine déjà le temps gagné si ça peut marcher en traitement par lot..

Heuh
Great, thanks !

...
Maybe that the auto-transient detection would be some kind of thing a bit like the "automatic region detection" which is already here, but with a very short release, and adding the action to drop a marker each time the audio signal is louder than -Xdb ?
(ahem, this is non-dev talk, so don't bother if it is too stupid :) )

[Wavosaur Main Developer]

Yes I see. We will test several algo to choose the best compromise.

i'm in the beta-tester team for liveslice. i'm sure that ohm (main-dev of liveslice) can help you getting started on the algo, just write him an email to the address he provided on the website.

I don't know this project.

All algo are developed by Wavsoaur Team. We don't use other algo (source code). But why not to have an idea.

Could you explain me the algo principle ,if you know it?

i don't know the algo, but i think of it like it just searches for rapid changes in the amplitude (that would be the first start of a transient) and then goes back to the nearest zero-crossing in the sample.
