Audio censoring is the process of automatically detecting and replacing specific spoken words in an audio recording with bleep sounds, silence, or alternative audio effects. Bleep That Sh*t! uses OpenAI's Whisper speech recognition model to generate word-level timestamps, then replaces selected words with customizable bleep sounds — all processed locally in the browser using WebAssembly. No software download or account required.
HOW TO CENSOR AUDIO IN 4 STEPS
UPLOAD YOUR AUDIO
Drag and drop any MP3 file or audio from MP4, MOV, AVI, or WebM video. Your file stays on your device — zero bytes are uploaded to any server.
AI TRANSCRIBES EVERY WORD
OpenAI's Whisper large-v3 model (via Hugging Face Transformers.js) transcribes your audio with word-level timestamps. Apply profanity lists or select any words manually using exact, partial, or fuzzy matching.
CHOOSE YOUR BLEEP
Pick from 6+ sounds: classic TV bleep (1kHz sine wave), brown noise, dolphin chirps, T-Rex roar, silence, or upload your own. Adjust volume and buffer timing.
DOWNLOAD CENSORED AUDIO
Preview your censored audio, then download. Compatible with all podcast platforms, social media, and media players. No watermarks, no quality loss.

100% PRIVATE AUDIO CENSORING
Unlike cloud-based censoring services, Bleep That Sh*t! processes audio entirely in the browser using WebAssembly and Web Workers. Zero bytes of audio data are transmitted to any server during free-tier processing. No server uploads, no cloud storage, no third-party access.
GOOD TO KNOW
- File size: Browser processing works best for files under 10 minutes. For longer recordings, use our cloud processing option (supports up to 2 hours).
- Speech only: Whisper AI transcribes spoken words. It cannot detect or censor words within singing, music, or non-speech audio.
- Accuracy: Works best with clear speech and minimal background noise. Heavy accents or overlapping speakers may reduce accuracy.
- Browser support: Requires a modern browser with WebAssembly support (Chrome 80+, Firefox 78+, Safari 15+, Edge 80+).
