I've tried to create a true tone with Nokia Multimedia Converter 2.0. Input WAV - Output for 3300 WB-AMR with recomended 15.85 kbps. The amr file was created successfully but the 3300 needs file extension .awb. So what is wrong....? The file has the right codec...the extension is wrong but i renamed it....3300 won't play it. What have i to do to get it working?
Anybody got an idea?
