Split 16 hours audio book in segments of 30 min and export them

Good day

I know the “detect silence” feature but in this case it wont help. How can I automatically split a 16 hour recording in lets say 30 minute parts and then export them as mp3s.
I know Wavelab can do this and I only find information about wavelab in this case.

thank you very much!
Cheers

I don’t know of a one-click way to do this but I would do it like this:
Create a 30 min long empty event, duplicate it 32 times, and select the corresponding event range for exporting each time.
A quick vid:


Some shortcut tips:

  • double click inside the range creates the empty event
  • ctrl+d for duplicating events
  • p for setting range to selected event

Can you place named cycle markers on each end of each segment then mixdown with cycle markers instead of locators? I’ve done this when scoring segments for movies. Works very well. From the manual: Cycle Markers

Hi,

Select the Split Tool (scissors). Find the first 30 minutes. Hold down the Alt modifier and cut/split at the time is 30 minutes. Thanks to the Sake modifier, the cut/Split will repeat until the end of the Audio Event by using the length of the first cut/Split (i.e. 30 minutes in your case).

Then you can either select the Audio Events one-by-one, set the locators to the selection [P] and create the Cycle Marker. Select the next Audio Event and repeat.

Or you can use Render In-Place with the proper settings (to make sure the rendered files are not going to be merged). Once you render all at once, you can find the rendered files in the given folder. These are your result files.

At the end, you will use 2 click: Split (with the Alt modifier) and Render In-Place.

Cool trick. Didn’t know this worked with split.

That was my initial thought but I was under the impression that the alt+split was linked to grid value which only goes up to 1000ms. Good to know, thanks!

thank you Martin, that was very helpful and worked perfectly!!
cheers
