# nausea

This is a simple audio spectrum visualizer.  It works well with the mpd

music player daemon, as well as anything that can play or record audio to stdout.

It was originally inspired by the visualizer

screen of ncmpcpp.  It depends on the fftw3 and curses libraries.

To visualize system audio, you must first make a fifo using mkfifo, and then use

something like aplay or arecord to redirect audio into your fifo:

````

mkfifo /tmp/audio.fifo

aplay > /tmp/audio.fifo

````

You need to add the following to your mpd.conf.  The format is important

because it's the only one supported for now.

    audio_output {

        type "fifo"

        name "Pipe"

        path "/tmp/audio.fifo"

        format "44100:16:2"

    }

Then start the program with:

    $ nausea

Alternatively specify the path of your mpd fifo with:

    $ nausea 

To try it out with color support try:

    $ xterm -bg black -fa "Monospace:pixelsize=12" -e ./nausea -c

    

    

## Man Page

### DESCRIPTION

The nausea program performs a discrete fourier transform and plots the spectrogram in real time using curses. It can also just display the audio waveform. The current implementation expects the input stream to be 44.1kHz, 16-bit little endian and 2 channels. The default fifo path is /tmp/audio.fifo.

#### Commandline options
