Hear the difference

A NOISY VOICE, FIXED HERE

A voice with steady fan noise behind it, and what the noise fix makes of it. Play it, flip between before and after, and turn AMOUNT to hear how much it takes out.

FX-02 / NOISE SAMPLEBEFORE / AFTER
0:00 / 0:10

A quieter background can also cost parts of the voice. Our measured noise-removal examples compare pauses, words and consonants from the same reading, including a second speaker the denoiser cannot remove. How we test explains the sample sources, pass marks and limits. Our audio repair sample library brings the before/after downloads for all eight fixes together.
