Hi there, Cathy! This is Marc. Thanks for reaching out to the community.
Yes, there are noise reduction options you can use on Windows 11 Home, even without built-in enterprise tools. Microsoft now includes a basic “Voice Focus” and “Automatic Noise Suppression” feature in some apps like Teams, but for system-wide audio output cleanup, you’ll need third-party software.
Popular free options include Krisp and NoiseTorch (Windows port), which filter out background noise in real time for both input and output audio. Paid tools like NVIDIA Broadcast (requires RTX GPU) or RTX Voice also offer excellent denoising, while apps like NoiseGator or Voicemeeter Banana can route audio through noise gates and filters.
Let me know if this helps, or if you need further assistance.
Best regards,
