Frequently Asked Questions

What does the Audio Studio tool do?

The Audio Studio adjusts volume, trims long silent sections and applies a voice clarity filter to make speech easier to hear. It is intended for quick fixes rather than full professional mastering.

Is the utoolsy Audio Studio secure?

Yes. Audio files are processed on your device using WebAssembly. They are not uploaded to utoolsy servers, so your recordings remain private.

Will processing change the content of my audio?

Volume adjustments keep content intact but louder or softer. Silence removal can cut long pauses between speech, and the voice clarity mode applies EQ-style filters that may slightly change the sound character while improving intelligibility.

Which audio types are supported?

Any audio format that your browser can play is usually supported, including MP3, WAV, M4A and OGG. If you encounter issues, converting the file to MP3 before upload often helps.
