NARRATE
Studio sound
Select a take, tick a few options, and hit Enhance — CourseSmith runs a chain of audio steps so a home recording comes back cleaner, clearer and evenly loud, at the same length. It runs on our own servers, shows its progress on the button, and keeps the original muted underneath so one undo brings it back. Part of the Pro plan.

Studio voice tone
Evens the voice toward the standard speech spectrum: less boomy, clearer, gently compressed.
Rebuild muffled audio
For phone or Zoom-quality takes only: restores the missing highs above the call’s cut-off.
Even out loudness
Brings the take to broadcast level (−16 LUFS), so nothing is too loud or too quiet.
