Best Noise Suppression Software for Gaming, Discord, and More
Mike Rule
Updated on
Clear communication is more important than ever, whether for video calls, online meetings, or live streaming. However, background noise—such as barking dogs, keyboard clicks, or air conditioning hums—often disrupts these interactions, making it difficult to hear and be heard. Users across various forums have expressed frustration with poor audio quality, which can hinder productivity, concentration, and the overall experience. To address this, noise suppression software has become essential. Here are top 7 best noise suppression software free for Discord, gaming, live streaming, video calls, and more, to eliminate unwanted noise in real-time communications.
Winxvideo AI
- Price: $45.95 for a lifetime license
- Platforms: Windows 11/10/8/7/earlier
- Free trial: Permanent with a 5-minute limit
Winxvideo AI is a comprehensive video and image software that leverages AI-driven tools to improve both audio and visual quality. Among its standout features are AI noise suppression and voice filtering, which help clean up audio tracks in videos by removing background noise and enhancing the clarity of spoken words. The AI noise suppression tool intelligently analyzes the audio track and reduces unwanted environmental sounds such as hums, clicks, or static.
The voice filter, powered by AI, isolates the human voice from other sounds, improving speech intelligibility. Users can fine-tune these features with settings like the Noise-Attenuation Limit (dB), which controls the degree of noise reduction, and Post-Filter Threshold, which helps to fine-tune the output after filtering. Additional volume control features like Gain (± dB) allow users to adjust the overall volume, ensuring audio levels are consistent. These features are particularly useful for content creators, vloggers, and those working on professional video projects.
