Whisper allows you to listen to your microphone through your speakers. It's useful for testing your microphone or for listening to your voice.

This app requires both PulseAudio and Pipewire to be installed on your system.

Pirewire is available as the default audio server on

This app does more or less the same thing as Helvum does, but with a simple UI: when you have more than a couple of apps playing audio, it gets quite hard to use Helvum.

Furthermore, Whisper shows only physical inputs, while the afroamentioned show all inputs, including audio streams created by apps and virtual ones.

Whisper can also control the microphone gain and the speaker volume.
