Questions
Is there a free AI audio enhancer with no signup and no limits?
Yes, VoiceStudio. All features are free, with no time limit, no watermark and no signup.
Is my audio uploaded anywhere?
No. Recording, noise removal, editing and export all run inside your browser on your own device. Your work is autosaved in your browser's storage, on this device only.
Does it work offline?
Yes. After your first visit the app is stored by your browser, and you can install it like a normal app.
Which files can I open and export?
MP3, WAV, M4A/AAC, OGG, Opus and FLAC in. MP3 or WAV out, with presets for podcasts, voiceovers, YouTube and call recordings.
Can I change the filters after recording?
Yes. Your original recording is kept untouched; filters apply while playing and exporting, so you can adjust them any time.
Can it remove echo?
It reduces it. The AI noise suppression also cuts room echo and reverb between and after words, most with the Clean Voice and Podcast presets. A very echoey room is only partly cleaned, so recording close to the mic still helps.
Is VoiceStudio an audio enhancer?
Yes. It removes noise, reduces echo, adds clarity with EQ, evens out the level with a compressor and sets the loudness on export. It is built for speech, not music.
Is this audio enhancer online unlimited?
Yes. No limit is set by us. Very long files (several hours) need a lot of memory, so on phones keep files under about an hour.
Is there a free alternative to the Adobe Podcast voice enhancer?
Yes. Like Adobe Podcast Enhance it removes background noise from speech, but it runs on your own device: no account, no upload and no daily limit. It also reduces room echo, though Adobe’s regenerated voice can go further in a very echoey room.
Does it work on my phone?
Yes, in a current browser on Android or iPhone. You can record there too.
Which browsers are supported?
Current Chrome and Edge give the best results. Safari and Firefox also work.
Make your next recording sound expensive.
Free forever. Works offline after the first visit.
