r/OnlineESLTeaching on Reddit: Free alternative to Krisp noise suppression software for teaching online?
October 3, 2020 -
I just spent a half hour looking for this and can't find anything that does not require an Nvidia graphics card. Seems really odd that for something so simple and useful, it's so difficult to find online for free.

Good noise suppression software for microphones
Not sure what your set up is...that would help alot in understanding. For me personally I record on dynamic mics and edit on logic pro. I use a plugin called Expander that really works well. Any audio editing software has an amazing noise reduction that once you learn how to use it, is worth the investment in learning it. So let me know! More on reddit.com

October 3, 2020What's the best free noise cancellation software to install?
You can check out NVIDIA's RTX Voice app or NVIDIA Broadcast, but I believe you need an NVIDIDA GPU to utilize either. I don't know of any other free to use noise cancellation software though. I would suggest Krisp, but it's a paid for program. More on reddit.com
