Sound analysis matlab

I need to do simple measurements on some birds call with matlab (see attached samples), The script must be able detect "notes" (independant sound, preceded and followed by a silence during at last 5 milliseconds) and track de dominant frequency throught them to define each point where the slope of the shift of frequency change of more than 10 %. all the points must be stored in a csv file like that : note_1, time_1, freq_1, int_1,time_2, freq_2, int_2,...time_n, freq_n, int_n,time_n, note_2, time_1, freq_1, int_1,time_2, freq_2, int_2,...time_n, freq_n, int_n,time_n, ... note_n, time_1, freq_1, int_1,time_2, freq_2, int_2,...time_n, freq_n, int_n,time_n, time = time (milliseconds, 0 for the beginning of the first note) freq = frequency (KHz) int = intensity (dB) The scrpit must displays the spectrogram and plot the note on it with their connected points as in attachement (can be the same color for all notes - just add a note number label) It also must be able to proceed all the files in a choosed folder.
