To study s60 the 3rd edition symbian os,I used an instant message software,like icq, to connect a PC with a Nokia N95 mobile phone. And the speech encoding/decoding system is the GSM ANR-NB algo. The GSM-AMR-NB applied at Nokia mobile is embedded readily in phone.
However,that applied at PC is downloaded from the website and compiled by me.
Bad. I can catch the sound from mobile speaker ,which is sent by PC. But I do not get the sound from
pc speaker,which is sent by mobile. That is to say,the encoding preocessing at mobile is not working in contrast that decoding processing is working.
Any comments would be appreciated.
