Statischer Sound Equalizer für ALSA |
|
|
Zuerst installieren wir:
sudo apt-get install swh-plugins ladspa-sdk
Dann editieren wir:
$ gedit ~/.asoundrc
Wir erweitern die Datei oder erstellen diese falls nicht vorhanden
pcm.equalized {
type plug
slave.pcm "equalizer";
}
pcm.equalizer {
type ladspa
# The output from the EQ can either go direct to a hardware device
# (if you have a hardware mixer, e.g. SBLive/Audigy) or it can go
# to the software mixer shown here.
slave.pcm "plughw"
#slave.pcm "plug:dmix"
# Sometimes you may need to specify the path to the plugins,
# especially if you've just installed them. Once you've logged
# out/restarted this shouldn't be necessary, but if you get errors
# about being unable to find plugins, try uncommenting this.
path "/usr/lib/ladspa"
plugins [
{
label mbeq
id 1197
input {
#this setting is here by example, edit to your own taste
#bands: 50hz, 100hz, 156hz, 220hz, 311hz, 440hz, 622hz, 880hz,
# 1250hz, 1750hz, 2500hz, 5000hz, 10000hz, 20000hz
#range: -70 to 30
controls [ -1 -1 -1 -1 -5 -10 -20 -17 -12 -7 -6 -5 -5 0 0 ]
}
}
]
}
Durch Anpassen der controls verändern wir den Sound. Allfällig laufende Programme (Rhythmbox) müssen nur neu gestartet werden.
Weiter gehts:
gedit /etc/pulse/default.pa
Code:
$ gksudo gedit /etc/pulse/default.pa
Den blau markierten Text austauschen...
Code:
### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)
#load-module module-alsa-sink
#load-module module-alsa-source device=hw:1,0
#load-module module-oss device="/dev/dsp" sink_name=output source_name=input
mit:
Code:
load-module module-alsa-sink device=equalized
Und sichern.
