I'm doing a physics experiment for school, for which I am measuring the reverb time for specific frequencies in a room. What I did was record a 1000 Hz sound, and some time after it, and looked at its FFT on Audacity to see the intensity of just 1000 Hz at a given time. Manually, I can do this for t=0.2s, 0.4s... so on and compare the values, but I want an algorithm that shows me the decay of the 1000 Hz sound from the FFT by plotting a graph of the intensity vs time of the 1000 Hz. Is there an existing software that does this? I am not able to find it anywhere.(adsbygoogle = window.adsbygoogle || []).push({});

(this is my first question here, sorry for any mistakes.)
