MathMod allows to plot 3D mathematical surfaces, described by implicit or parametric. MathMod is a portable interactive plotting and graphing program for Windows, Linux, MacOSX and many other platforms. To plot a function simply type it down and the graph will be. This figure is mapped to a color intensity scale and then drawn on the graph, with pure black representing -128dB and pure white representing 0dB.Top Software Keywords Show more Show less Plot high quality graphs of mathematical equations and data with this easy-to-use software. 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. Available cross-platform for Windows, Linux and Mac, its primary function is the visualization of mathematical data and functions.

The graph features two different plots if the audio is stereo, otherwise just the one plot will be displayed. Gnuplot Gnuplot is one of the best-established graphing tools, popular among intermediate and advanced users.

Works with any audio files that can be loaded into WavePadįFT 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).

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. Firefox Download For Mac 10.

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.

The advantage of this is that Mac 3D Grapher is generally easier to use and the resulting 3D graphs are of higher quality. But a better option is to download Runiter's Mac 3D Grapher and plot your 3D formulas there.

Perform a spectral analysis of audio at any one point in time, or across an entire duration To plot 3D graphs in Mac OS X you could use the default Grapher utility that is pre-installed in Mac.
