Bleep censor: bleep or mute swear words in video and audio

Yes. Audo censors the first 2 minutes of each video or audio file free, 3 times a day, with no sign-up, no watermark, and Keep the background included. Whole files are $0.03 a minute ($1.80 an hour), re-running edits from the transcript with Censor only these is $0.01 a minute ($0.60 an hour), and Keep the background adds $0.05 a minute ($3.00 an hour), with no subscription—see pricing.

Switch on Keep the background on Audo before running the censor. Most online profanity filters mute or bleep the combined stereo track, which cuts an obvious hole in your background music, beat, or game sound. Audo separates the voice from music and sound effects first, applies the 1 kHz bleep or silent mute with 8 ms fades only to the voice, and keeps the untouched background playing smoothly underneath.

Upload your MP3, WAV, M4A, or FLAC song to Audo, switch on Keep the background, and choose Mute for a clean radio-edit vocal drop or Bleep for a tone. Because fast singing and slang are harder to transcribe than speech, Audo shows every flagged lyric starred in its line: check repeated choruses, add any missed slang under Also censor, untick false matches when signed in, and press Censor only these to re-render from the transcript for $0.01 a minute.

Your picture quality and lip sync stay identical to the original. Audo replaces spoken words in place to the exact sample without cutting frames or changing duration, and copies the video stream directly without re-encoding on MP4, MOV, MKV, WebM, and AVI files up to 10 GB. Each censored word is also marked in the transcript, so opening the result in Auto captions automatically masks swear words as f*** in your video subtitles. Audo censors sound and captions rather than blurring faces or objects on screen.

Audo's built-in swear-word lists—Strong for major profanity and slurs, or Strong and mild to catch words like damn and hell too—cover 7 languages: English, Spanish, French, German, Portuguese, Italian, and Dutch. Under Also censor, you can add up to 200 custom words, phrases, private names, or prefix wildcards like frick* (plus a Leave in allowlist) across all 60 transcribed languages. Set Swear words to Only my words to redact names or phone numbers alone.

In CapCut and Kapwing, free censoring means scrubbing the timeline, splitting audio around every swear word, and placing bleep clips by hand (with a watermark and 4-minute 720p cap on Kapwing Free). Adobe Premiere Pro ($22.99/month) offers bulk mute and bleep on desktop, though you must type or import your own word list and it mutes mixed-in music too. Bleepify caps uploads at 2 GB and locks Music Mode behind paid plans or a $9 pass. Audo runs in your browser up to 10 GB with no sign-up, built-in 7-language profanity lists, untouched video quality, and pay-as-you-go vocal separation from $5.

ChatGPT and Claude cannot natively bleep or mute words inside audio and video files on their own. Once you Add Audo to your assistant via Audo's MCP server (https://audo.ai/mcp), ChatGPT, Claude, Claude Code, Codex, and Cursor can call censor_audio—choosing bleep or mute, profanity level, custom words, allowlists, and Keep the background—and return a clean MP4, MP3, or WAV, or call the REST API directly from code.
