Exporting file with labels in batch process

I have create Sound FIlter because I want to get rid of first part of audio file which contains sound. This sound I want to remove. So I created the Sound Filter and added it to batch. But I did not find out how to export the parts of the file which contain the labeled sounds. I know there is option in menu, but how to do it in batch processing? Also my problem is that i want to remove only the first sound detected (not just make is silent).
