I try to detect some audio signals(pure sine) in near real time. I know that I will get some latency. In the start I try to detect some tones of 10Khz in a duration of 75ms. That is achieved by a Goertzel filter. What is the prefered technique for that issue? I thought of making a little buffer that will always be detected by the Goertzel, but this sounds bad because I don't know when the the signal starts. Can you give me some help or idea ? Thanks

You'll have to do something like I am trying to do here (please do contact me if you fix my inaccuracy issues though) NAudio WaspiLoopback Goertzel
You can also take a look at: Decoding DTMF from a WAV file which have helped me a lot in getting something that can barely work, but it's a pretty good start.
