Audio FFT Graph\ The FFT analyzer graph is designed to illustrate characteristics of audio at only one point in time. It takes a small sample of audio and plots the sound frequency in Hz against the audio intensity in decibels. If the audio is in stereo two lines will be plotted on the graph, otherwise just the one plot will be displayed.
Audio TFFT GraphThe TFFT graph maps the audio intensity of the frequency spectrum across time for the duration of the audio clip, representing the intensity through color. On this graph the x-axis is time and the y-axis is the frequency with the decibel intensity being mapped to the color intensity scale, with black representing -128 dB and white representing 0 dB.
Both the discrete and temporal fast fourier transform frequency analysis graphs can be created/opened from the Tools tab and both graphs will update in real time as you move to different positions in the audio file, or even as you play the audio so you can better see what is happening in the audio. So, download WavePad audio analyzer software to take a closer look at audio and learn how to analyze voice patterns and more.
