Want to hear your sound in microphone? Here’s a stupid simple tool to the job in Linux.
It’s Whisper, a new free and open-source GTK4 application, allowing listen to microphone through your speaker. Which, is useful for testing your microphone or for listening to your voice.
As the screenshot shows, the app is quite easy to use. Just select the microphone and speaker from the list, and click ‘Connect’. Then, you can say something or make some noise through microphone to see the magic.
As a GTK4 application, it follow system color scheme by switching between light and dark automatically. However, it needs both PulseAudio and Pipewire to make things work, which is default in Pop! OS 22.04, Ubuntu 22.10, Ubuntu 23.04, Fedora 35/36/37, etc.

As mentioned above, this application requires Pipewire audio server. For current Ubuntu 22.04 LTS, it’s NOT the default, though you can enable it by following this tutorial (NOT recommend for beginners).
