thx for ur reply.
however, i cant do the blind listening test becoz it not show any
output of data.
so i need another solution to measure the sound quality. i hope u can
suggest me a software to measure the codec sound quality which without
network.

There really is no good objective measurement, other than to use a listening
panel. The problem is that the codec is designed around the human perception
and that has to be taken into account.

A codec that works well in one language may work very poorly with another.
I am surprised people can understand tonal languages through the cellphone
at all.
