Hiss removal — common questions

How do I remove hiss from a recording for free?

Upload your recording to FixTheFile and select "Clean up audio noise". The hiss is reduced automatically, and your file downloads instantly.

What causes hiss in old recordings?

Hiss often comes from analog tape, cassette recordings, or low-quality microphones picking up constant background electrical or environmental noise.

Will this completely eliminate the hiss?

FixTheFile significantly reduces hiss and static, though very heavily degraded recordings may retain some residual noise.

Does this affect the voice or main audio quality?

FixTheFile's AI is designed to separate steady background noise from the main audio, preserving voice and music quality as much as possible.

Can I use this on a digitized cassette or vinyl recording?

Yes — this works well on recordings transferred from cassette, vinyl, or old tape, which commonly have hiss or surface noise.
