A Quick Glance of the Top 7 Noise Suppression Software

What is Noise Suppression Software

Noise suppression/cancelling software is a tool designed to reduce or eliminate unwanted background sounds from audio recordings or live streams. This technology works by detecting and isolating non-essential noises, such as fan hum, traffic, or room echo, while preserving the clarity of the primary audio source, like a voice or musical instrument. It is widely used by content creators, podcasters, musicians, and professionals in industries where clear audio is critical. Advanced noise suppression software uses algorithms to filter out disturbances in real time or during post-production, enhancing the overall sound quality. This ensures that recordings are crisp, clear, and free from distracting ambient noise, making them more professional and enjoyable for listeners.

Noise suppression software is essential for anyone looking to improve the clarity and professionalism of their audio content. Whether you're recording podcasts, videos, or music, or even participating in online meetings, background noise can easily disrupt your sound quality, making it harder for your audience to focus on what really matters—your message. With noise suppression software, unwanted sounds are automatically filtered out, allowing your voice or music to come through crystal clear. This not only enhances the listening experience but also elevates the overall quality of your work, making it more polished and engaging. Additionally, in live streaming or virtual meetings, noise suppression software can eliminate distractions, ensuring smooth and uninterrupted communication. It's an essential tool for anyone who wants to deliver clear, professional-grade audio in any environment.

Here are the 7 top noise suppression software solutions you can count on to ensure smooth, high-quality recording and editing.

How to Remove Audio Noise Using VideoProc Converter AI

Step 1. Free download VideoProc Converter AI, click on the the "Audio AI" icon on the main interface, which will bring you to the Audio AI workplace.

Step 2. Upload your file. You can choose to import either an audio file or a video file that includes audio.

Step 3. Apply AI noise suppression and preview

Check Noise Suppression, choose the preferred AI model, and adjust the Noise Attenuation Limit, Post-Filter Threshold, and Volume Control accordingly.

• Noise Attenuation Limit (dB): This setting determines the maximum noise suppression level. A higher limit removes more noise but may reduce audio quality, while a lower limit preserves natural sound. For optimal results, set it to 6-12 dB for light reduction and 18-24 dB for moderate noise suppression.
• Post-Filter Threshold: This controls additional noise removal after the initial suppression. A lower threshold (0.01-0.02) offers lighter filtering for quieter environments, while a higher threshold (0.03-0.05) targets moderate noise, such as background hum or chatter, ensuring clarity in the main audio.
• Volume Control: This feature allows users to adjust audio levels. If noise reduction causes a drop in volume, users can increase the signal to enhance clarity and overall enjoyment of the content

Tips:

• For a clear before-and-after comparison, you can toggle off Noise Suppression to listen to the original audio, then turn it back on to hear the enhanced version.
• Click "Apply to All" to apply your changes to all audio files in your project.

Step 4. Export your audio.

Once you're satisfied with the result, you can choose to export the entire file or use the green knobs at both ends of the audio waveform to trim and export only the selected portion.
