Here are some methods to obtain the frequency https://ccrma.stanford.edu/~pdelac/154/m154paper.htm

The closest to calculating frequency I've found in EZAudio (1.1.5) is to use the FFT delegation and find the maximum bin in the resulting buffer and correlate it to frequency. There's a sample project for that, it might be enough for your tuner app.
