QuietPlease v0.3 • For macOS 14+ (SwiftUI & Accelerate DSP) Meet QuietPlease.
A Real Audio Compressor Detector for Your Room.
QuietPlease runs a real-time audio compressor detector on your room microphone. Threshold, ratio, knee, attack, release, Peak vs RMS detection, a sidechain voice filter, and 32-band matched-filter sound training all work just like a studio plug-in—except when the room gets too loud, it puts a full-screen Quiet Please sign on every display.
Designed for Real Classrooms, Tracking Rooms, and Production Studios
See 15-second room history, the dB transfer curve knee, Peak vs RMS step response, and a 32-band spectrum analyzer at the same time.
Record 3 seconds of talking or applause so QuietPlease catches conversation without triggering during music playback.
Calibrates to real dB SPL, uses ~3% of one CPU core alongside any DAW, and immediately discards audio samples.
