I think 1.0 is the most natural and least arbitrary value for the
parameter. (Speed of sound = 1 mach).
Also, 1.0 is the value that conforms to the OpenAL 1.0 specification
and all the implementations that follow the OpenAL 1.0 specification.

I think it would be nicer for the default to be 1.0 and for
applications that want to use doppler with a velocity unit other than
the mach to set the parameter explicitly, instead of having an ugly
constant like 343.3 being introduced into the specification as a
