mvc

An MPD music visualizer, based on curses. It works by reading the fifo output of an MPD instance. At the moment it performs a Fast Fourier Transform of the raw PCM data provided by MPD, but a beat detection is going to be implemented to gain more precision.

Requirements

The fifo output of MPD needs to be enabled. To do so, simply place this in your mpd.conf:

audio_output {
    type                    "fifo"
    name                    "my_fifo"
    path                    "/tmp/mpd.fifo"
    format                  "44100:16:1"
}

This is allowing MPD to create a file (the location is hardcoded right now so it must be /tmp/mpd.fifo) and write it with raw PCM data in realtime. Path and format variables MUST be the same displayed above. By reading that, mvc is able to compute a frequency spectrum of the current track played.

Building

Makefile-based.

make all

To install:

sudo make install

Usage

Simply run:

mvc

Note that an instance of MPD must be running for mvc to work, otherwise the fifo file doesn't exist.
