This is by design: when you specify an event-time distribution, it can occur anywhere in the range spanned by the distribution.
Right now there is no "flag" to tell scaper to avoid overlapping events, so you need to ensure this yourself by specifying event times that don't overlap. You can do this either by explicitly setting the time for each event, or by setting your distribution ranges such that they don't overlap.
An alternative option is to simply sample soundscapes in a loop until you get one that meets your requirements. If you set no_audio = True
when you call generate()
it's extremely fast to generate a soundscape, so you could just generate soundscapes in a loop and check them for overlapping sounds, and when you get a soundscape without overlapping sounds you can save the jams file and then call generate_from_jams
to obtain the corresponding audio.
In the future I may add an explicit option to control the overlap, but I don't foresee having time to do this in the near future.

@justinsalamon Thanks for the information. I was looking for this as well :)

Thanks,one point that I don't understand, how to explicitly set the time for each event in the tools?

Please read the scaper tutorial and documentation, it's explained there.
