A free Audo AI alternative for full-length recordings
This Audo AI alternative cleans whole recordings for free. Audo has a huge toolbox and pay-as-you-go pricing, but its free enhancer stops after the first minute. VoiceStudio removes noise from the whole file, however long, without credits.

Why people switch from Audo
Long recordings
A one-minute free preview does not help with a 40-minute interview.
No credits to track
Nothing is charged per minute, so re-exporting with new settings costs nothing.
Files that must stay private
Your recording is processed on your device and never sits on a server, even for a day.
Fine control
Set the gate, EQ, compressor and limiter yourself, not just one strength slider.
Why you might still use Audo
Muffled or distorted audio
Audo lists muffled sound and distortion among the problems it fixes, and at Full strength it rebuilds the voice.
Video
It cleans the sound in a video and gives the video back. VoiceStudio opens audio only.
Everything in one place
Transcripts, captions, vocal removal and video tools live in the same site.
Questions
What does Audo give you for free?
When we checked in November 2026, its audio enhancer and noise remover processed the first minute of a file for free, 3 times a day, without sign-up. Whole files are paid with credits.
How much does Audo cost for a full file?
Its pricing page lists 5 credits a minute for noise removal at 1 cent a credit, so about $3 for an hour. Credit packs come with bonuses, and credits do not expire.
Is there a free Audo AI alternative for long files?
Yes, VoiceStudio. It runs on your computer, so there is no server cost to pass on. The only limit is your device’s memory; on phones, keep files under about an hour.
Does VoiceStudio rebuild the voice like Audo’s Full strength?
No. It removes noise and shapes your real recording. It does not generate a new voice, so it cannot rescue badly muffled audio, and very echoey rooms are only reduced.
Can VoiceStudio clean the audio in a video?
Not yet. It opens audio files only. Save the audio from your video first, then open it here.
Is VoiceStudio part of Audo?
No. It is independent and has no connection to Audo AI.
