Why Synthetic Speech Needs Fake Room Noise
Episode 6230
Published 1 week, 2 days ago
Description
Synthetic speech can stop completely between sentences, leaving gaps of true digital black that sound unnatural on playback. This episode digs into why engineers fill those holes with room-tone beds, how a real fix for this show landed around minus sixty dBFS on a phone, and why a constant quiet background beats a perfectly clean pause. Along the way: what room tone actually contains, why filmmakers record thirty to sixty seconds of nobody doing anything, and why audiobook noise-floor specs collide with loudness normalization.
