Ask HN: Voice Quality Measurement Tool

Since we are all working remotely more these days, we are relying on our conferencing setup to work well. One frequent issue I see is that voice of speakers is very muffled due to bad microphone setup or other wireless issues. Showing some immediate feedback to the speaker will be helpful here. I came across a voice quality assessment metric called as PEAK. Is there an app or widget that shows this as an overlay as you speak into the microphone? Having this integrated into Webex or Zoom will be very useful.
