My application is receiving an InputStream containing audio in PCM 8bits mono 8Khz which, utltimately, comes from a telephone call.
Could somedy tell me how to detect DTMF tones inside this audio stream?
I had a look at JTAPI, but it looks like it's a spec made of interfaces only and that implementations are vendor-dependant, so it does not seem to help as I am already receiving the stream from a telephone independant lib.
Thanks a lot in advance
