Question 1

What can the Audio Trimmer & Noise Cleaner do?

Accepted Answer

It lets you trim MP3/WAV clips visually on a waveform and reduce background hiss using spectral noise reduction.

Question 2

Are my audio files uploaded to a server?

Accepted Answer

No, trimming and noise cleaning happen entirely in your browser, so your audio files never leave your device.

Question 3

Will the noise cleaner remove background voices or music, not just hiss?

Accepted Answer

Not really, the spectral noise reduction is designed to reduce steady background hiss and hum, not isolate or remove other voices, music, or complex background noise.

Question 4

Is it free to use?

Accepted Answer

Yes, it's free and doesn't require an account.

Question 5

Why does processing a long audio file feel slow?

Accepted Answer

Because trimming and noise reduction run in your browser, longer files take more time and processing power, and performance depends on your device.
