Then at every point in time and frequency, an intensity calculation is done and a dB figure is calculated (between -128dB and 0dB). The y-axis is used for frequency (in Hz) and depicts the spectrum of the audio at any one point in time (like the FFT it goes up to half the sample rate of the audio). The x-axis is used for time (in hh:mm:ss format) and spans the duration of the audio selection. TFFT GraphThe TFFT graph works by plotting the intensity of the frequency spectrum of the audio across time, and represents intensity through color. The frequency of the graph ranges from 0Hz to half the sample rate of the audio, whilst the intensity range goes from -128dB to 0dB.

The graph features two different plots if the audio is stereo, otherwise just the one plot will be displayed. Export TFFT graph as an image file - PNG, JPG, GIF or BMPįFT GraphThe FFT graph works by taking a small sample of audio and plotting a graph of frequency (x-axis, in Hz) versus intensity (y-axis, in dB).Works with any audio files that can be loaded into WavePad.The FFT updates instantly, and the TFFT graph cursor updates to the same point as in the audio file Navigate through, or even play your file, and see real-time updates to both graphs.Graphs are plotted using frequencies up to half the sample rate of the audio and intensities up to 0dB.Graphs are presented in a simple and intuitive fashion, allowing for optimal viewing and analysis.TFFT has zoom ability as well as a color intensity specifier to choose the intensity at which colors are represented in the graph.FFT has ability to zoom in on either x-axis or y-axis to see graph in more detail.Perform a spectral analysis of audio at any one point in time, or across an entire duration.
