What’s the difference between noise suppression and denoising?
Asked on Oct 07, 2025
Answer
Noise suppression and denoising are both techniques used in AI audio processing to improve sound quality, but they serve different purposes. Noise suppression aims to reduce or eliminate unwanted background noise in real-time audio streams, while denoising is typically applied to recorded audio to clean up noise artifacts.
Example Concept: Noise suppression is often used in live audio applications, such as during a video call, to minimize background sounds like keyboard clicks or air conditioning. Denoising, on the other hand, is applied post-recording to remove consistent noise patterns, such as tape hiss or electrical hum, from audio files.
Additional Comment:
- Noise suppression is crucial for live audio clarity, often integrated into conferencing software.
- Denoising algorithms analyze the entire audio file, making them suitable for post-production tasks.
- Both techniques can be implemented using AI models trained to distinguish between noise and desired audio signals.
- Choosing between them depends on whether the audio is live or recorded and the specific noise characteristics.
