How do I show spectrum in audacity?
To select Spectrogram view, click on the track name (or the black triangle) in the Track Control Panel which opens the Track Dropdown Menu, where the required view can be selected..
What does plot spectrum do in audacity?
Plot Spectrum takes the selected audio (which is a set of sound pressure values at points in time) and converts it to a graph of frequencies (the horizontal scale in Hz) against amplitudes (the vertical scale in dB). Plots are made using a mathematical algorithm known as a Fast Fourier Transform or FFT.
What is frequency spectrum of sine wave?
Frequency spectrum of a signal is the range of frequencies contained by a signal. For example, a square wave is shown in Fig. 3.5A. It can be represented by a series of sine waves, S(t) = 4A/π sin(2πft) + 4A/3π sin(2π(3f)t) + 4A/5π sin(2π(5f)t + …)
