What is Audo Studio?
Audo is a set of online tools centered around "cleaning up audio", with its official slogan being professional sound quality without a recording studio. It integrates noise reduction, echo cancellation, vocal enhancement, transcription, recording, and screen recording into a single interface, allowing files to be processed by simply dragging them in. The official claims that it has handled more than 10 million files since 2021. Another feature is that it also provides an Assistants API, enabling this set of processing to be integrated into tools such as ChatGPT, Claude, and Cursor. It places cleaning and transcription in the same workflow: cleaning first and then transcribing, which usually leads to better text accuracy.
Who is it for?
- Podcast and video creators: Apply noise reduction first before editing after recording.
- Editors and education and training teams that process interview and course recordings.
- Project assistants who hold frequent remote meetings and need to clean up audio files.
- Instructors who record online courses and lectures, who need to organize the audio into a publishable version after class.
- Developers who want to integrate audio processing into their own products.
Key features
6Voice Enhancement
Elevates ordinary recordings to a sound quality close to that of a recording studio. The official offers intensity levels ranging from subtle to full, allowing you to test with a gentle setting first and then increase the intensity step by step.
Noise Reduction & Echo Cancellation
Eliminates background noise while preserving human voices; echo cancellation makes voices in remote meetings sound closer to the microphone, eliminating the hollow room effect, with the most noticeable difference in rooms with heavy reverb.
Transcription
Converts speech to text. The official version can identify who said what, making it much faster to revise meeting minutes after a call than to listen to the recording from scratch.
Recording & Screen Recording
Record audio, screen and camera directly within the platform, with on-the-fly trimming and cleaning after recording, eliminating the need to switch between multiple apps.
Format and Size
Supports common audio and video formats, with a single file size cap of 100 MB. It can be exported as WAV, MP3, M4A, or FLAC, which is sufficient for delivery to editing or podcast platforms.
API and Assistant Integration
Offers the Assistants API, which the official states can be called in environments such as ChatGPT, Claude, Claude Code, Codex, Cursor, etc. It adopts a pay-as-you-go model with no subscription required.
