HushMic
HushMic runs DPDFNet deep-learning noise suppression on your microphone and exposes the cleaned audio as a virtual PipeWire microphone, so any call or recording app can simply select it. Keyboard clatter, fans and street noise are removed while your voice stays natural.
Processing is local and CPU-only: audio never leaves the machine and no network connection is ever made. A tray menu switches models, picks the microphone and sets the suppression strength, and the built-in A/B test window shows your raw and cleaned signal side by side so you can hear and see the difference before a call.
Compatibility: Uses the C library of the system (may need glibc 2.35 or later)

Usage
HushMic is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.
This AppImage uses the C library of the system and may need glibc 2.35 or later. It does not run on distributions that use a different C library (such as musl on Alpine Linux) or an older glibc.
Running HushMic on Linux without installation
Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.Beware! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!
Download the HushMic AppImage and make it executable using your file manager or by entering the following commands in a terminal:
chmod +x ./*.AppImageThen double-click the AppImage in the file manager to open it.
Sandboxing HushMic
If you want to restrict what HushMic can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.
Updating HushMic
If you would like to update to a new version, simply download the new HushMic AppImage.
The HushMic AppImage also can be updated using AppImageUpdate. Using this tool, HushMic can be updated by downloading only the portions of the AppImage that have actually changed since the last version.
Integrating AppImages into the system
If you would like to have the executable bit set automatically, and would like to see HushMic and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.
Note for application authors
Thanks for distributing HushMic in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.
Pro Tips for further enhancing the HushMic AppImage
Please consider making the HushMic AppImage self-contained, so that it does not depend on the C library of the system and runs on more distributions: ship the C library including its loader (ld-linux-*.so.*) and use it to launch the application, or link statically.
Thanks for shipping AppStream metainfo inside your AppImage. Please open a pull request on https://github.com/AppImage/appimage.github.io/blob/master/data/HushMic if you have changed it and would like to see this page updated accordingly.
