PulseAudio Real Time Playback

Purpose: You may want to hear yourself live while doing voice training, and if you are using an operating system like Fedora, you will want to have some way to listen to yourself through the microphone live.

The following command will install Pulse Audio Volume Control, which you can then use to listen to yourself while training.

sudo dnf install pavucontrol
pacat --record --latency-msec=1 | pacat --playback --latency-msec=1

Wear Headphones!

When you run this command, it will listen to the microphone live, and if you are not actively wearing headphones, you will immediately get a feedback loop.
