Pro Tip: For podcast recordings and voiceovers, start with 40-60% noise reduction to remove background hiss without making the voice sound unnatural. For music recordings, use lower settings (25-40%) to preserve audio fidelity. The colorful slider helps visualize the strength - yellow for light, green for balanced, and blue for strong noise reduction. Always compare the results before/after to ensure you're getting the best balance between noise removal and audio quality!
