How to Denoise a Recording on iPhone Without Destroying the Voice

The problem this product is built around

Noise reduction is tempting because background is easy to see in a waveform. But room tone, breath and consonants can share frequencies with voice, and aggressive processing sounds metallic.

How WaveCraft solves it

WaveCraft estimates the steady noise floor before processing and reduces it frequency by frequency. The strength control changes subtraction, and the project keeps the original for comparison. If noise is not steady, the honest result may be a new recording. Open the WaveCraft product page for current availability and plan details.

A practical workflow

1. Listen to speech and a section that should be silence.
2. Run default reduction and compare consonants and sibilance.
3. Raise strength only when remaining noise is worse than artifacts.
4. Improve recording position when noise changes with every word.

What to check before you trust the result

Denoise cannot recover clipped speech or erase a bad room without a trace. Listen on headphones and keep the original.

Who this workflow is for

Use it when noise is steady and the voice is already intelligible.
