The output sample rate is determined by the MPEG stream input. The only 
option provided by the library is to generate output at exactly 1/2 
this sample rate -- mad_stream_options(stream, 
MAD_OPTION_HALFSAMPLERATE).

The library does not provide general resampling facilities; if you want 
to produce output with an arbitrary sampling frequency, you will have 
to resample the output yourself or with another library. See for 
example the resample.c code in madplay.
