Feature to detect and delete areas of lower volume?

Wondering if there is a feature that auto scans/detects/deletes what I call downtime; areas of video/audio that have lower volume levels, such as in interviews, where the interviewee isn't talking... they're waiting for the interviewer or production team.

My normal workflow for interviews before I actually edit content:

• Drop the entire interview in a sequence
• Expand the audio track
• Zoom in to see waveform detail
• Make rough in/out deletes to remove the downtime

Maybe there's a quicker workflow? Please share yours if so!

My interviews typically last an hour or so. The downtime in this is costly. It increases costs to transcribe, increase time to create proxies, and increases the time my clients have to sit and wait to see the usable footage. It would be sooooo helpful to have this process automated. Greatly appreciate any help with this!

Thanks!
