Please consider using https://github.com/dilawar/wav . It has a header only c++11 implementation.
This work started off as a fork of Dr. Taylor’s work http://people.msoe.edu/~taylor/examples/wav.htm (dead link). On master branch the project has diverged a lot.
We provide a C++ class to read WAV file. It's content are stored in an array which we finally write to a csv file. You can plot this csv file using any application of your choise. We only support non-compressed WAV file.
On other branches, this project has diverged a lot.
Run make to build the project. This will create a binary parseSpeech.
cmake .
make
./parseSpeech -f /path/to/input.wav
In the end, you will have a /path/to/input.wav.csv file. It has two columns: time and signal value at that time.
