What does fixed numbers mean ? #161

Closed xiaoyangnihao closed 3 years ago

xiaoyangnihao commented 3 years ago

@jmvalin In the function: lpc_from_bands() in line 226 in script freq.c, there are three fixed numbers 320/12/38., can you tell me what each of them means?

   /* -40 dB noise floor. */
   ac[0] += ac[0]*1e-4 + 320/12/38.;
