These are copyright material, and so cannot be distributed with this test software. + +The files, containing test vectors, which are supplied with the G.726 specification, should be +copied to itutests/g726 so the files are arranged in the same directory heirarchy in which they +are supplied. That is, you should have file names like + + - itutests/g726/DISK1/INPUT/NRM.M + - itutests/g726/DISK1/INPUT/OVR.M + - itutests/g726/DISK2/INPUT/NRM.A + - itutests/g726/DISK2/INPUT/OVR.A + +in your source tree. The ITU tests can then be run by executing g726_tests without +any parameters. + +To perform a general audio quality test, g726_tests should be run with a parameter specifying +the required bit rate for compression. The valid parameters are "-16", "-24", "-32", and "-40". +The test file ../test-data/local/short_nb_voice.wav will be compressed to the specified bit rate, +decompressed, and the resulting audio stored in post_g726.wav. +*/ + +/* Enable the following definition to enable direct probing into the FAX structures */ +//#define WITH_SPANDSP_INTERNALS + +#if defined(HAVE_CONFIG_H) +#include
