Usage instructions / Sensible Pulseaudio names.

[kingsly]

Thanks for this awesome piece of software! :-)

This script should work for most typical pulseaudio setups with only one sound card.

It also overrides the confusing default PulseAudio names "Null Output" "Monitor of Null Output" etc. with more user friendly ones.

It creates both usable mic sources so users can choose whatever shows up in the software they want to use the mic with.

Feel free to modify as you see fit or if you need me to make any changes or make it more user friendly let me know.

Usage: pa-denoise.sh /path/to/librnnoise_ladspa.so

#!/bin/bash
RNNOISEPATH=$1
MICSOURCE=`pactl list sources short|grep input |awk '{print $2}'|head -1`
echo "Using ${MICSOURCE} as raw mic input. If you have multiple sound cards override the value for MICSOURCE in the script."

Tell me how it should work? I did, I see that the microphone hears, but the virtual microphone Alt Denoised Mic Monitor does not hear

If I use the module for echo cancellation, the noise is eliminated

#Used to perform acoustic echo cancellation between a designated sink and source
load-module module-echo-cancel source_name=alsa_input.platform-sound_0.seeed-8ch source_properties=device.description=MicrofoneNoise
set-default-source MicrofoneNoise

And how to use renoise to eliminate all backgrounds, music, extraneous sounds and so that only speech is heard?
