Questions
Is it free?
Yes. Editing in Audo's browser editor and checking loudness are always free; convert, cut, and join are free for the first hour of a file, noise removal and voice enhancement for the first minute, and transcription for the first 2 minutes, a few times a day, with no sign-up. For longer files, you pay as you go (pay once from $5, with no monthly subscription) — from $0.01 to $0.08 a minute ($0.60 to $4.80 an hour) — see pricing.
What happens to my files?
They stay private. Uploads are deleted after 24 hours, and free results after 1 hour.
Which files work?
Audio as WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, AIFF, and video as MP4, MOV, MKV, WebM, AVI. Files up to 10 GB work without an account, and up to 10 hours when signed in. To change formats first, use Convert audio, or pull the sound from a video with MP4 to MP3 or Replace audio in video.
Can ChatGPT, Claude, or an AI agent edit my files with Audo?
Yes. Connect Audo's MCP server to ChatGPT, Claude, Claude Code, Codex, or Cursor to clean up speech, transcribe with speaker diarization, cut filler words and pauses, or run multi-step workflows in plain words, then download the finished file or open it in Audo's browser editor to fine-tune any cut. Connect your assistant.
