mppcava - Console-based Audio Spectrum Visualizer for ALSA
mppcava [-v] [-p config]
Exit with ctrl+c
or q
.
The mppcava command is a bar spectrum audio visualizer for the Linux terminal using ALSA, pulseaudio or fifo buffer for input.
This program is not intended for scientific use. It's written to look responsive and aesthetic when used to visualize music.

NOTE: only works in ncurses output mode.
Key | Description |
---|---|
up / down | increase/decrease sensitivity |
left / right | increase/decrease bar width |
f / b | change foreground/background color |
r | Reload configuration |
c | Reload colors only |
q or CTRL-C | Quit C.A.V.A. |
If mppcava quits unexpectedly or is force killed,
echo must be turned on manually with stty -echo
.
All options are done in the config file, no more command-line arguments!
By default a configuration file is created upon first launch in
$XDG_CONFIG_HOME/mppcava/config
or $HOME/.config/mppcava/config
,
but mppcava can also be made to use a different file with the -p
option.
Sending mppcava a SIGUSR1 signal, will force mppcava to reload its configuration
file. Thus, it behaves as if the user pressed r in the terminal.
One might send a SIGUSR1 signal using pkill
or killall
.
For example:
$ pkill -USR1 mppcava
Similarly, sending mppcava a SIGUSR2 signal will only reload the colors from the configuration file, which is the same as pressing c in the terminal. This is slightly faster than reloading the entire config as the audio processing does not need to reinitialize.
$ pkill -USR2 mppcava
