I want to edit my audio real-time.

On Windows there's Voice Meeter & (required) Virtual Audio Cable, I want to edit out my keyboard clicks (by adding a noise gate), any way to do this here in Ubuntu?

A tutorial on how to setup would be appreciated.

It is possible to mix audio in Puseaudio similar to voicemeeter, but not so easy to add noise gate that i know of.

Better to use JACK sound server for mixers and effects.

For mixer that will also host effects try: non-mixer

You can use Audacity which is an audio waveform editing platform, with many plugins and tools for editing audio files. Or you can use a DAW application like Ardour which you can use to edit audio and filter it through plug-ins to get your final product.

There's also abgate which is a noise gate plug-in, that can be used with Ardour. Some others may also get installed when you install Audacity and Ardour, and there are several other plug-in packages available to install as well, which may also include other noise gate options.

You can simply install either of them from Ubuntu Software and then just start using them.

  • Audacity is not for real-time

After trying all the hacks and tools (Audacity, audio recorder etc ) Finally found this Open Broadcaster Software (OBS), which is super easy and just does the job.

In Settings → Audio, I was able to select:

. Audio output (Either desktop or earphone or bluetooth also possible)
. Mic - (Desktop | earphone)

For Source, I selected Screen Capture (XSHM) to capture the entire desktop or can keep it blank as well.

To install:

sudo add-apt-repository ppa:obsproject/obs-studio && sudo apt install obs-studio
