DTMFdetector and generator. Was used standard C++,so DTMFdetector and generator completely cross platform.It used robust and reliable fixed-point algorithm, so can fast work on fixed-point architecture.
DTMFdetector library and/or application that reads in the specified audio file and returns/outputs whether DTMF detected and/or list of detected digits. May have GUI and command line interfaces.
www.open-source-soft.narod.ru/DTMF_JAVA.7z Description: DTMFdetector and generator is written completely on JAVA. It use fixed-point format so it fast and can be used on any platforms, including CLDC configuration.
http://www.open-source-soft.narod.ru/dtmf_cs.7z C# DTMFdetector and generator classes. It was used completely fixed point arithmetic, so algorithms as fast as possibly.
