Definition
Noise reduction is the process of removing unwanted background noise from video audio tracks, improving clarity and professionalism of spoken content.
Noise Reduction explained
Background noise includes HVAC systems, traffic, keyboard clicking, room echo, electrical hum, and ambient sounds. Noise reduction algorithms analyze the audio frequency spectrum to distinguish speech from noise and attenuate unwanted frequencies. AI-powered noise reduction (like RNNoise, NVIDIA Broadcast, or Adobe Podcast) significantly outperforms traditional spectral noise gates by using neural networks trained on thousands of hours of noisy and clean audio pairs. Clean audio is critical for video content: viewers tolerate poor video quality more than poor audio quality. For voiceover content, noise reduction should be applied before text-to-speech to ensure clean source audio.
