CurvFit ™ is a curve fitting program for Windows. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked and/or valleys data.

CurvFit is another improved productivity example do to using Calculus (level) programming … ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error, etc.). Helps learn 1) whether math model is good for given data; 2) convergence implies a reasonable solution; 3) how to select new starting initial parameter values. See comments in EX*.? files for ideas on how to converge via solvers. Interpolation, extrapolation, & Hardcopy Plot options are now available.

Industry problems with solutions over the past twenty plus years have been put into a textbook to show the power of Calculus (level) Problem-Solving. The textbook is on our website at fortranCalculus.info/textbook/welcome . The software architect behind Calculus Compilers is Joe Thames (read about Joe on our About page).

Help improve science and engineering productivity by supporting Joe Thames’ MetaCalculus University Rollout efforts, visit metaCalculus.com/campaigns.html, in developing MC Fortran. (There has been little if any corporate funding of Joe’s work for many years!) Help future science & engineers get jobs upon graduation. With MC Fortran, one increases their productivity by a factor of twenty!

This sophisticated piece of software turns your computer into a modern, State of The Art spectrum analyzer giving you features that go far beyond the possibilities of any stand-alone hardware unit.An important advantage of your new analyzer software is the fact that your computer monitor is a far better means of displaying analyzer measurments than any LED or LCD bar. By making use of standard computer operations your analyzer software will store your personal settings or analyze audio data you may have previously recorded. What we had in mind while developing the PAS Analyzer was maximum flexibility, so we decided to equip it with its own test tone oscillator.While the analyzer is connected to your soundcards input the oscillator signal is feeding the outputs. Of course there is more than a 1 khz sine wave in the oscillator, its actually giving you various waveforms and noise. In Compare Mode the output of your soundcard is constantly being checked against whats coming in at the cards input sockets allowing you to evaluate the quality of any given signal chain. Now let me give you some real life examples for the use of the PAS Analyzer Detecting and eliminating room modes sound reinforcement
