Looking for real time voice changer through Linux?

Question

I am looking for a real time voice changer for my Chromebook on Linux.

Does anyone know which one I can use?

Answer 1

Install some packages:

sudo apt install pavucontrol libsox-fmt-pulse sox

Check your voice in normal mode by loading module-loopback:

pactl load-module module-loopback latency_msec=100

Unload module-loopback to stop listening your voice:

pactl unload-module module-loopback

Use the next command to change your voice in real time and listen to it:

sox -d -d pitch -700 contrast 100 echo 0.9 0.9 5 0.6

Change pitch, contrast and echo settings the way you like. And then you could use these settings in some programs like skype selecting them on pavucontrol's Recording tab:

• pactl load-module module-null-sink
• sox -t pulseaudio default -t pulseaudio null pitch -700 contrast 100 echo 0.9 0.9 5 0.6
• pavucontrol
