Hi, thanks for the report and sorry for the late reply.
Have you tried using the example program?
from dtmfdetection.
I was unable to reproduce your problem. I created a new .NET Framework console app, copied the examples and ran it while playing DTMF sounds via this video and my mobile phone touchpad. Both worked.
However, the website you linked didn't work for me either. I suspect there is something wrong with the site. Also, when analyzing microphone audio, I had to place my mic very close to the loudspeakers of my mobile.

Hi bert2
thank you for your hints.
I discover that in both case my failures seems related to the volume of the sound.
For both (generator website and the video 911) I have to keep very high volume, and in that way it works!
The environment is a room very quiet and seems a little strange to me to need so higher volume; excuse me but in my first attempt I have tried with a low volume, around a middle of the maximum possible.
Closing the issue, I'd like to express the wish to have some parameter for tune the sensibility of recognition process, if is possible to implement.
Or if that parameter is already existent, if you can indicate me please.
Thanks for your attention and for drive me to the solution.
Warm regards,
Francesco

You can use NAudio to boost the volume of your audio stream before you pass it to the analyzer. I'm not sure how this is done exactly, but the documentation should help.
