Audo

Audo is an online AI audio cleanup toolkit that makes voice recordings sound clearer by removing noise, echo and distortion, for podcasters, video creators, teachers and anyone recording speech outside a studio. It runs in the browser with nothing to install, and it skips subscriptions entirely: you get free daily use on short sections and pay per minute with credits for longer files. The same tools are available through an API and as actions for AI assistants.

What is Audo used for?

Audo is used to rescue and tidy recordings before they are published or shared.

• Enhancing interviews, lectures and video voiceovers recorded in noisy or echoey rooms
• Removing background noise from Zoom calls and phone recordings
• Separating vocals from music or splitting songs into vocals, drums and bass
• Transcribing audio with speaker labels and exporting SRT captions
• Removing filler words and long silences from spoken content
• Converting, cutting, merging and leveling audio and video files

Who Audo is best for

Audo suits podcasters, YouTubers, course creators, journalists and small teams who clean audio occasionally and do not want another monthly subscription. Developers who need voice enhancement inside their own apps can use the API. Music producers who need studio-grade restoration of instruments should use dedicated plugins instead, since the enhancer is designed for voices.

Audo pricing

As of October 2026, Audo is free to try: every tool works on the first part of a file, from the first minute for the enhancer up to the first hour for simple edits, a few times per tool per day, without signing up. For whole files up to 10 hours, you buy credits at one cent each, and each tool costs between 1 and 8 credits per minute. The enhancer and noise removal cost 5 credits per minute, the vocal remover 8, and transcription 3. Credit packs start at $5 for 500 credits on the first purchase, with larger packs from $10 to $100 adding bonus credits. Credits never expire, and new accounts do not receive extra free credits.

Audo limitations

• Free use only covers short sections of files for the heavier tools
• The voice enhancer strips out music and other sounds, so it is not for music mixes
• Uploads are deleted after 24 hours and free results after one hour, so download promptly
• Audo Studio, the older app, has moved to a separate site, which can confuse returning users

Audo vs alternatives

Adobe Podcast offers a well-known speech enhancer inside Adobe's ecosystem, a good choice if you already pay for Creative Cloud. Cleanvoice focuses on removing filler words, mouth sounds and silences from podcasts. Auphonic is built for automatic leveling, loudness normalization and podcast publishing workflows. Krisp removes noise live during calls rather than after recording. Audio Cleaner AI is another browser cleanup option. Audo wins when you want a wide set of voice and file tools, no subscription and credits that never expire.

Tips for getting started with Audo

Test the enhancer at full strength on the first free minute, then try a lower strength if voices sound processed. Run noise removal before transcription to improve accuracy. If you clean audio every week, compare a larger credit pack, which adds bonus credits, against a subscription tool, and connect Audo to your assistant only for the specific tools you plan to use.
