# Compress audio similiar for people perception

We don't feel much low and very high frequencies

This is example of setup pulseaudio and dirty script to stick to a sink for some plugin

# Use

sudo nano /etc/pulse/default.pa && systemctl restart --user pulseaudio.service; journalctl --user -u pulseaudio.service --since "-1m" -f

```pa

### Some stuff

# sudo apt install pulseaudio-equalizer

load-module module-equalizer-sink sink_name=EQ_SvenSPS sink_master=alsa_output.pci-0000_05_00.1.hdmi-stereo-extra1 sink_properties='device.master_device="alsa_output.pci-0000_05_00.1.hdmi-stereo-extra1"device.de>
