     13 The

     15 program performs a discrete fourier transform and plots the spectrogram
     16 in real time using curses.  It can also just display the audio waveform.
     17 The current implementation expects the input stream to be 44.1kHz,
     18 16-bit little endian and 2 channels.  The default

     20 path is
     21 .Pa /tmp/audio.fifo .
