# Audo
> Audo: pro sound without the studio. Audio and video tools, workflows, and a browser editor for you and your AI assistant: clean up, transcribe, cut, and more.

## Free, no sign-up
Inspect HTTP status and Content-Type in response.headers before interpreting response.body: 202 is unfinished work, 200 JSON may be a manifest or transcript, and 4xx/5xx is an error. Complete polling and output validation client: https://audo.ai/docs/api?utm_source=llms_txt&utm_medium=agent#responses

Each tool has a free allowance with no sign-up, a few times a day per tool (pay-as-you-go from $5 for full files, with no monthly subscription and credits that never expire). For example, noise removal does the first minute free, and convert the first hour. Uploads up to 10 GB, 2 at once from one address.

Get MP4 clips and a JSON report with titles, reasons, scores, and source ranges. — `curl -F file=@video.mp4 https://audo.ai/api/try/workflows/clips -D response.headers -o response.body`
  - Podcast-ready episode (`podcast_ready`): Remove background noise, shorten long pauses, and set podcast loudness at −16 LUFS. Intermediate audio stays lossless, with one final MP3 encode. — `curl -F file=@episode.wav https://audo.ai/api/try/workflows/podcast_ready -D response.headers -o response.body`

- Saved voices for `clone_voice` (with an API key or MCP): save a recording or `design_voice` preview once via `POST https://audo.ai/api/v1/voices` (MCP `save_voice` / `list_voices`), then pass `voice_id` instead of uploading a sample each time.
- Every tool, with its options: https://audo.ai/api/openapi.json
- A free result cut short includes finishUrl: the person pays there (from $5, no sign-up), the whole file runs, and the status link then gives the whole result.
- Out of free uses: the request still takes the file, and its 429 has details.finishUrl: the person pays there (from $5, no sign-up), the whole file runs, and details.statusUrl then gives the whole result.

## Languages
- Transcribe (`transcribe_audio`) and Align a script (`align_script`) and Remove filler words (`remove_fillers`) and Censor audio (`censor_audio`) and Translate audio (`translate_transcript`) and Find highlights (`find_highlights`) and Shorten transcript (`shorten_transcript`) and Add captions (`add_captions`) support 60 languages, detected automatically: af, ar, as, az, bg, bn, bs, ca, cs, da, de, el, en, es, et, fa, fi, fil, fr, gl, gu, he, hi, hu, hy, id, is, it, ja, kk, kn, ko, lt, lv, mk, ml, mr, ms, nb, ne, nl, or, pa, pl, pt, ro, ru, sk, sl, sv, sw, ta, te, th, tr, uk, ur, vi, yue, zh.
- Text to speech and Subtitles to speech speak 87 languages on Eleven v4 / v4 Turbo, 130 languages on Gemini 3.8 Flash, and 100+ on Gemini 3.8 Flash-Lite; Censor audio includes built-in swear-word lists in 7 languages (en, es, fr, de, pt, it, nl) and custom words in 60 languages; Voice cloning speaks 30+ languages; Voice changer speaks 29 languages on Eleven Multilingual STS v2 and 39 languages on HeyGen Voice STS; Generate music sings in the language of the prompt and lyrics; Sound effect generator takes English descriptions; Translate subtitles translates into 60 languages.
- Every other tool works on the sound or picture, so it works in any language.

## Speakers
- Transcribe includes automatic speaker diarization and labels who speaks when (Speaker 1, Speaker 2, and so on) in its JSON, TXT, and VTT, unless `speaker_labels` is false. SRT has no names. Details: https://audo.ai/transcribe.md

## Whole files
- With an API key, omitted free pays for whole files if the balance covers them, otherwise tries the free portion if quota remains. Use free=true to prohibit spending; paid whole-file requests need free=false and an approved positive max_credits. Add -H "Authorization: Bearer $AUDO_API_KEY". Keys, and auto-refill so credits never run out (only the person turns it on): https://audo.ai/keys?utm_source=llms_txt&utm_medium=agent
- MCP server (sign in; the same free tier, then credits): https://audo.ai/mcp
- Connect an assistant (ChatGPT, Claude, Claude Duet, OpenAI Dots, Meta Muse, Grok Bot, Raycast, Claude Code, Codex, Cursor, Gemini CLI, VS Code, Copilot CLI, Antigravity, Zed, OpenCode): https://audo.ai/setup?utm_source=llms_txt&utm_medium=agent

## Pages
Every tool page on the website, for people, by family as https://audo.ai/all-tools?utm_source=llms_txt&utm_medium=agent lists them: each tool's page, then the pages for one job under it. Add .md to any of them for its Markdown version.
