pulsemeeter VS key-mapper

There is also this for mixing in PulseAudio only github.com/theRealCarneiro/pulsemeeter I have tried similar methods to route audio streams in PulseAudio (using null-sinks and loopback-sinks) and never been happy with results, too much latency

I think most people use Voicemeeter Banana on Windows. This is similar but for Pulseaudio. https://github.com/theRealCarneiro/pulsemeeter

If you mean on linux then Pulsemeeter is literally the linux version of voicemeeter that uses pulseaudio

Here is a project that is an alternative to VoiceMeeter https://github.com/theRealCarneiro/pulsemeeter

You can use helvum to route audio. Helvum with Easyeffects covers most of the usage of voicemeeter. If you want similar type of UI like voicemeeter then check Pulsemeeter.

Pulsemeeter alternative for voicemeter banana.

There is also pulsemeeter for mixing in PulseAudio that is intended to be similar to Voicemeeter, but i would not expect it to be a good low-latency solution

If this bother you, you can check Pulsemeeter. It looks kinda similar to voicemeter banana.

There is another tool in development called Pulsemeeter. The goal is have similar UI and workflow like voicemeter banana.

This may help you!

Another option is key-mapper which runs as a systemd service and lets you map all kinds of things to other things.

Key-mapper

Being a previous windows user I have a mindset that I shouldn't download non mainstream or non trusted applications on my system especially the ones that have admin access or physical device access . I wanted to remap my keyboard in such way which allows me to use capslock key as backspace and alt_r key as escape. setxkbmap and Xmodmap isn't giving required results or I am not too advance to use it properly . I recently stumbled upon this program key-mapper but it requires admin access so should I trust it for daily use. ( I am not a developer and thus does not understand what any of the code does )

There's Key Mapper which I haven't tried yet (still on my 100% rubberdome at the moment so no need) but it looks very promising.
