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 built-in bleep sounds or silence. Browser mode handles short local files with WebAssembly; Studio cloud is available for longer recordings.

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, max 1 GB).
- 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+).
FREQUENTLY ASKED QUESTIONS
Can I censor audio online for free?
Yes — Bleep That Sh*t! lets you censor audio files up to 10 minutes entirely free in your browser. No account needed.
What audio formats are supported?
MP3, WAV, and audio extracted from MP4, MOV, AVI, and WebM video files. The tool exports censored audio as part of the original file format.
Can I censor a podcast episode?
Yes. Upload your podcast recording (MP3 or supported media), review the AI transcript, select words to bleep, and download the censored version. Processing time depends on file length, browser capability, and whether you use Studio cloud processing.
Is my audio private?
Short browser-mode files can be processed locally on your device with WebAssembly. For longer files or phone uploads, Studio cloud processing clearly indicates when upload-based processing is used.
How accurate is the transcription?
Whisper AI works best with clear speech and minimal background noise. Accuracy varies with accents, overlapping speakers, and audio quality. You can always manually adjust the transcript.

You can bleep spoken words detected by the AI transcription. The tool works best with speech — it cannot isolate or censor words within singing or music.
