Peak Detection (Steps 3 and 4) Due to the sampled nature of spectra obtained using the STFT, each peak (location and height) found by finding the maximum-magnitude frequency bin is only accurate to within half a bin. A bin represents a frequency interval of Hz, where is the FFT size. Zero-padding increases the number of FFT bins per Hz and thus increases the accuracy of the …

Use a peak detection algorithm. You already mentioned that you experimented with one, which certainly can be used and improved. However, detect multiple peaks in a longer window and neglect the signal if there are too many peaks (probably more that 3 is sufficient, judging from the data presented.) Check the autocorrelation of the signal.
