Step 1: Identify the Hiss Frequency
Hiss is steady white/pink noise typically concentrated above 3kHz in your recording.
Step 2: Sample the Hiss Profile
Highlight a pause in your speech where only the mic hiss is audible.
Step 3: Run AI Spectral Gating
Apply AI Noise Reduction. The algorithm attenuates the continuous high frequencies in silent areas while letting speech pass through naturally.
