Plays a tune
If the argument is a file name (@pxref{File name syntax}), play the tune
recorded in it. The file format is first the tempo as an unsigned 32bit
little-endian number, then pairs of unsigned 16bit little-endian numbers for
pitch and duration pairs.
If the arguments are a series of numbers, play the inline tune.
The tempo is the base for all note durations. 60 gives a 1-second base, 120
gives a half-second base, etc. Pitches are Hz.
