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.
