Hi Brianna,
I understand your query is to generate a line plot for a Fourier transform on a frequency vs time graph.
According to the theory of Fourier transform, the Fourier transform provides information about the intensity of frequencies present within a given time window. As a result, plots generated from Fourier transform analysis typically represent either the amplitude versus frequency or amplitude versus time relationship. However, when attempting to create a plot in the frequency versus time domain, a single line plot is not feasible due to the presence of multiple frequency components in the data at any given time (unless the data consists solely of a single harmonic component).
To address this, a spectrogram is employed to visualize the frequency content over time. The spectrogram allows for the representation of multiple frequency components at different time intervals, providing a comprehensive view of the frequency-time relationship in the data. By utilizing a spectrogram, one can effectively analyse and interpret the frequency variations over time in each signal or audio data.
I hope this addresses your query.
Regards
Binaya
