Audo

What it does

Audo runs audio and video tools on audo.ai. It removes noise and echo, enhances voice, transcribes speech, cuts and merges files, removes silence, adjusts loudness, converts formats, and swaps a video's audio. People use the website; assistants such as ChatGPT and Claude connect through an MCP server; scripts and servers use a REST API. Everyday tools are free for the first part of a file with no sign-up, and longer work is pay as you go from $0.01 to $0.03 a minute with no subscription. Uploads are deleted after 24 hours.

Each tool has a price per minute of input, counted in credits where one credit is 1 cent. Remove noise and enhance voice cost $0.03 a minute, transcription and script alignment $0.02, and cut, remove silence, loudness, convert, join, audio swap, speaker leveling, and mixing $0.01. Media info is free. The free tier covers the first minute of noise removal and voice enhancement three times a day, the first 2 minutes of transcription, alignment, and filler word removal, the first hour of cut, silence removal, loudness, convert, and join, and the first 3 minutes of speaker leveling and track mixing. Every tool accepts video. Audio inputs include WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, and AIFF; video inputs include MP4, MOV, MKV, WebM, and AVI. Files can be up to 10 GB and 10 hours, or 100 MB without an account. Download links last 15 minutes, and files are deleted after 24 hours. Credits do not expire, and auto-refill can top up a balance at a chosen threshold. An OpenAPI file and llms.txt are published, and each page has a Markdown version.
