How to remove background noise from any call
Background noise on calls comes from three places: your microphone picking up your room, the other person's noisy environment, and echo. Here are your options, from free to best.
1. Use your app's built-in suppression
Zoom, Teams, and Discord all have basic noise suppression in their audio settings. Turn it on first. It is free and helps with light noise, but it usually only cleans your outgoing audio and struggles with heavy noise.
2. Improve your setup
A headset with a close mic, a quieter room, and soft surfaces all reduce noise before software has to.
3. Use dedicated noise-cancellation software
For heavy noise, keyboard clatter, or noisy participants on the other end, dedicated software like Krisp works far better. It cleans both directions and runs on top of any app.

FAQ
Start with your calling app's built-in noise suppression, then add Krisp's 7-day free trial, which gives full two-way noise cancellation with no credit card.
Most built-in tools only clean your own microphone. To clean incoming audio too, you need bidirectional software like Krisp.
