You mentioned there was already an open feature request?  uploading the
patch to the bugtracker should be a start.  AFAIK, most of the sox
developers are busy at the moment with real-life stuff.

I just cloned your blog and looked at it (a diff/cloned sox.git repo
would've been better), and it looks mostly OK...
Did you make sure log10_high_freq != log10_low_freq anywhere?  Otherwise
you might divide by zero:

   float log_scale = (float)p->rows/(log10_high_freq - log10_low_freq);

I'm only a simple C programmer and don't know the math behind
spectrograms, though.

(*) not sure how pick sox devs are about trailing whitespace,
    but other projects I work tend to be very picky :)
