Coding - COD

Note that all output files are binary files in SGI format (even if written on an alpha), written by the functions in RWLowLevel.c, int stands for a 4 byte integer, float for a 4 byte floating point number.

COD reads the files with the following suffixes appended to the stem of the sound file name:

i_T<step>.pitch

Fundamental frequency (float)

i_<mode -C>_T<step>.coupe_cod

Cut frequency between voiced and unvoiced band (float), generated running PetC with the -q option

_T<step>.envAR<method -E>_<order -o>

Envelope parameters of the sinusoidal part.

The output file is:

_T<step>_E<method>_o<order>_C<mode>.cod

Coded file.
