Each tool does one job on audio, video, or text, and multi-step workflows or Audo's browser editor combine them in one pass.

• Creators, podcasters, and teams with recordings to finish. Clean up noisy interviews, cut filler words and retakes by text, bleep swear words while keeping the music, clone your voice, design a new voice from a description, swap voices with speech-to-speech, generate voiceovers, dub from subtitles, or compose royalty-free music and sound effects, add captions, reframe wide video to 9:16, or finish everything in Audo's browser editor, with nothing to install.
• People who automate the first pass with an AI assistant. Ask ChatGPT, Claude, Claude Code, Codex, or Cursor to find and run Audo's tools and multi-step workflows in plain words, then download the result or open it in the browser editor for final tweaks.
• Developers and workflow builders. Every tool, saved voice, tool search, and multi-step workflow is also a REST API and MCP server, free to try without an account, then pay-as-you-go with no monthly subscription.

• Mastering songs. Remove noise, Remove echo, and Audio enhancer are tuned for spoken voices and turn music down; for songs, Vocal remover and Stem splitter separate vocals, drums, bass, and instruments.
• Scoring a whole film or game. AI music generator composes original songs, intros, and instrumental background music from text, and Sound effect generator makes sound effects up to 30 seconds long, but neither scores a whole film or game to picture.
• Live audio. Audo works on files, not on calls or streams as they happen.
• DAW music production or cinema color grading. Audo composes royalty-free music from text and handles multitrack voice and music lanes, transcript cuts, captions, overlays, and 9:16 speaker reframing in the browser editor, not MIDI instruments, VST plugins, or cinema color grading.

• Editing in the browser editor, recording in the browser, and checking loudness or key/BPM are always free; every other tool has a free allowance (up to an hour on everyday tools, 300 characters on voice generation, 3 voice designs, a 30-second music track, or 10-second sound effects), a few times a day, with no sign-up.
• Full files and scripts are pay-as-you-go: you pay once, with no monthly subscription, and your balance never expires.
• Audio and video uploads up to 10 GB and 10 hours (WAV, MP3, M4A, FLAC, OGG, AAC, Opus, MP4, MOV, MKV, WebM, AVI, SRT, VTT), and scripts up to 8,000 characters.
• Account files are deleted after 24 hours (signed-out free runs after 1 hour); saved voices stay in your account until you delete them.
• Sound and video tools work in any language. Transcription (with speaker diarization), subtitle translation, and script alignment work in 60 languages, bleep censoring includes swear-word lists in 7 languages (and custom words in 60), voice cloning speaks 30+ languages, voice changing supports up to 39 languages, text and subtitle-to-speech speak up to 130 languages, and AI music generation sings in the language of your prompt and lyrics.

AI assistants: ChatGPT, Claude, Claude Duet, OpenAI Dots, Meta Muse, Grok Bot, Raycast, Claude Code, Codex, Cursor, Gemini CLI, VS Code, Copilot CLI, Antigravity, Zed, and OpenCode. Add Audo once, then ask for audio and video work in plain words.

Your code: the API runs the same tools and multi-step workflows.
