Say. freqs = [100, 100, 200, 400, 1000, 100, 50] duration = 7. I want WAV with duration of 7 seconds. So from T=0 to T=1s tone should be 100Hz, from T=1 to T=2 sweeps from 100Hz to 200Hz and so on. WebChirp is an interesting new platform that allows you to share data using sound. This Python script allows you to convert a link, image or pdf into an audible chirp and vice versa. The decoding mechanism scans the recorded audio for any substantial amplitude levels, then a FFT is performed on each segment to find the maximum frequency present.

WebWe create a chirp of which the frequency increases from 20 Hz to 100 Hz and apply an amplitude modulation. >>> signal = chirp(t, 20.0, t[-1], 100.0) >>> signal *= (1.0 + 0.5 * np.sin(2.0*np.pi*3.0*t) ) The amplitude envelope is given by magnitude of the analytic signal. date on bottom of coke can
