for more beautiful sound
Now you can brush-up your music player more beautiful and adjustable.
Kernel change
Equalizer
- Kernel can be changed to more strict one. In terminal, type:
sudo apt-cache search linux-image-5.
Many kernels which can be applied to the system. Before we could choose "linux-image-5.13.0.30-lowlatency" that is best one of me, however, it is not available today*. So please try various kernels to find your favorite one.
Please copy that in terminal window and type:
sudo apt install "paste" -y
reboot
2. Sound equalizer can be installed at the digital level that does not affect sound quality.
sudo apt-get install libasound2-plugin-equal
sudo nano /var/lib/mpd/.asoundrc
Then in the empty file appeared on the terminal window, type or copy and paste:
pcm.!default {
type plug
slave.pcm plugequal;
}
ctl.!default {
type hw card 0
}
ctl.equal {
type equal;
}
pcm.plugequal {
type equal;
slave.pcm "plughw:1,0"; # NOTE this line MUST be your hardware device.
}
pcm.equal {
type plug;
slave.pcm plugequal;
}
Press ctl + x and return for saving the file. After reboot, type:
sudo -H -u mpd alsamixer -D equal
Now you can control/manipulate your sound more suitable for your audio systems as DAC, amplifier and speakers. This sound equalizer is very powerful that can control right/left sound independently. See the help/F1.
Please enjoy the most beautiful sound ever!!!
