excite

Functions

int main(int argc, char *argv[])

excite [ option ] [ infile ]

-p int
- frame_period \((1 \le P)\)
-i int
- interpolation period \((0 \le I \le P/2)\)
-n int
- noise type
  - 0 none
  - 1 Gaussian
  - 2 M-sequence
-s int
- seed for random number generation
infile str
- double-type pitch period
stdout
- double-type excitation

This command generates an excitation sequence from the pitch period in infile (or standard input), and sends the result to standard output. When the pitch period is nonzero, the excitation is to be a pulse train. When the pitch period is zero (i.e., unvoiced), the excitation is to be a Gaussian or M-sequence noise.

In the example below, the excitation is generated from the data.p and passed through an LPC synthesis filter. The speech signal is written to data.syn file.

excite < data.p | poledf data.lpc > data.syn

Parameters:

argc – [in] Number of arguments.
argv – [in] Argument vector.

Returns:

0 on success, 1 on failure.
