Cut one recording into smaller ones

Is it possible to cut one recording into several smaller pieces?

We have a recording with several hundred small pieces (1 to 5 minutes each). They are seperated by at least 5 seconds complete silence ( i. .e. zeros).

Now, we would like to cut this into smaller pieces and save each into a new file.

001.wav
002. wav
003. wav
etc.

The “cut markers” are the silent spaces of at least 5 seconds.

Can this be done easily with Wavelab? if so, how?

There are two ways to go about this. Auto Split and Montage.

You can use Auto Split and split according to Markers (either launching Auto Split through Ctrl+T on the open audio file or making Auto Split to work on your folder).

Or you can render according to clip names or marker names in the Montage.

It would be nice if you can share a screenshot of your file.

Is this the 5 seconds you were writing about? There are no visible markers here. In any case, you can open this file in the audio editor, use Ctrl+T then either split according to markers (by creating markers) or according to silence.

Yes, those are the empty space. Those empty spaces are the “markers” in itself.

Programaticaly this means: Running thourgh the file and save it to a new file until it comes to a (at least) 5 seconds of zeros, than start saving as a new file and so on.

If you have marked your silences as regions, there is an option to invert region to generate the rest.

Do we have to manually mark those spaces? This would be tiresome, because of hundreds of those spaces.

Look at the auto split dialog. There are many options to split a file.
