Thank you very much ! I'll try it and keep you informed.
I'm getting this error : ``` obj/linuxarmv6l/Release/src/main.o: In function `no_window::~no_window()': main.cpp:(.text._ZN9no_windowD2Ev[_ZN9no_windowD5Ev]+0x28): undefined reference to `HC_SR04::~HC_SR04()' obj/linuxarmv6l/Release/src/main.o: In function `no_window::~no_window()': main.cpp:(.text._ZN9no_windowD0Ev[_ZN9no_windowD5Ev]+0x28): undefined reference to `HC_SR04::~HC_SR04()' obj/linuxarmv6l/Release/src/main.o: In function `main': main.cpp:(.text.startup+0x118): undefined...
I had to comment ```HC_SR04();``` and ```~HC_SR04();``` in the HC_SR04 class. But it is still not working.
What about implementing the Praat algorithm for Pitch detection (http://www.ucl.ac.uk/~ucjt465/tutorials/praatpitch.html), besides PitchYinFFT and PredominentMelody ?
