int main(int argc, char *argv[])
mpir2c [ option ] [ infile ]
-m int
order of impulse response \((0 \le M_1)\)
-l int
length of impulse response \((1 \le M_1 + 1)\)
-M int
order of cesptral coefficients \((0 \le M_2)\)
infile str
double-type minimum phase impulse response
stdout
double-type cepstral coefficients
- Parameters
argc – [in] Number of arguments.
argv – [in] Argument vector.
- Returns
0 on success, 1 on failure.
-
class MinimumPhaseImpulseResponseToCepstrum
Convert minimum phase impulse response to cepstrum.
The input is the \(M_1\)-th order impulse response:
\[ \begin{array}{cccc} h(0), & h(1), & \ldots, & h(M_1), \end{array} \]and the output is the \(M_2\)-th order cepstral coefficients:\[ \begin{array}{cccc} c(0), & c(1), & \ldots, & c(M_2). \end{array} \]The conversion is based on a recursion formula.Public Functions
