Filter out calm parts of audio, let through really loud ones

# Filter out calm parts of audio, let through really loud ones

(Asked by: username_0 on 2018-11-20)

I have a project where I have one video and two audio tracks. The first audio is from the line-in microphone, the second one is from the room environment.

I only want the second audio to play when the db level is above -5db (meaning, only when the track gets loud). The point is for the second audio to just provide the laughter (loud part) and ignore its calm parts, which just adds unnecessarily noise.

Is there an effect or a filter for this? (it's like a cutoff limiter at X db, but the opposite, cutting off anything below a determined level of volume)

Thanks!
