Hi, Oh, sorry I misunderstood, I thought you wanted all noise cut out. I don’t know if this will work better since you want to include signals that are not much stronger than the background noise level, but have you maybe tried filters that reduce noise, like maybe anlmdn, rather than one that trims time-wise? For keeping pauses between, I think passing in the number of seconds for start_silence will do that for silenceremove, and you can trim the beginning if needed. If you want silence rather than the existing background noise, you could use silencedetect and use the metadata to generate and insert silence between sounds.
