Name

w_diff -  Compare two NIST SPHERE header waveform files

Synopsis

w_diff w_diff [-hvdws] [-cCSTR] file1 file2

Description

W_diff is a waveform comparing program. It can compare the SPHERE headers of two files as well as the data portions of two SPHERE files. If the files do not differ, a zero is returned by the program, otherwise a non-zero value is returned.

-cCSTR
Convert the files by the 'CSTR' used in a call to sp_set_data_mode()
-d
Compare the data portions of the files byte by byte.
-h
Print this help message.
-s
Compare the SPHERE headers of the files.
-w
Compare the waveforms of the two files after converting them using the conversion string in 'CSTR'. This is the default
-v
Set the verbosity level up by one, repeat the v for higher levels. A verbosity setting of 1 will provide a description of each tests outcome.

Examples

w_diff -vdws lib/data/ex1_01.wav lib/data/ex1_01.wav

Compare a file to itself.
w_diff -vdws lib/data/ex1_01.wav lib/data/ex1_10.wav: Compare a files of differing byte order.
