wave software

Harmonix by VanDerLee

With the Harmonix PhotoShop plug-in you can create complex waveforms. The waveforms generated by Harmonix are created by mixing (or superimposing for the more technically-minded) harmonic frequencies. All features of the waveforms are automatically scaled to fit the image (or selection of course) so you will not have to reconfigure an entire wave should you decide to change the image size.

audio software

SigJenny by NaTCH Engineering

SigJenny turns your PC into a flexible and powerful signal generator for free! It generates numerous different waveshapes, can sweep them or arrange them as tone bursts, graphically display them, and do a very good impression of a police car. The output can be a single frequency or swept, or a single or repeating tone burst. The input from a microphone can be shown and the output frequency can be specified as musical pitch!

NWin by NaTCH Engineering

NWin is a loudspeaker production test system using a standard soundboard. The user creates the tests they need and then combines them to create a test sequence. NWin can make sophisticated pass or fail decisions on frequency response (there are multiple measured frequency responses), polarity and other functions, and report on production performance.

sound software

Sound by Canadian Mind Products

Sound lets you mathematically create sounds in Java. You define your sounds in terms of 16-bit linear code for the waveform, -- an array of samplings. The U_Law.class will then convert that to (or from) *.AU mu-law 8-bit encoding format which you can then play with AudioPlayer.player.start(bis) in an application or with Applet.getAudioClip in an Applet. This is just a sample program. You would insert your own mathematical functions.

.NET KineticaRT Real-Time Data Simulator by KineticaRT Limited

The KineticaRT .NET Simulator Test Waveform Generator component provides simulated real-time data. Outputs include sine waves, sawtooth and noise, may be used with very little configuration and can provide reliable waveform test data. It is a member of the KineticaRT family of components, which can be used separately or in unison to build applications for instrumentation, hmi, control, monitoring and test automation.

visual software

Visual Terrain Maker by UNGSoft Developers Group

Visual Terrain Maker is a 3D-Modeling program allows visually create landscapes (maps) for games or other purposes. Works in XP/NT/2k. The program can export to Direct X file format(*.x). The program is not critical to the video adapters and drivers. Suitable for Dark Basic developers.

curve fitting software

CurvFit by Optimal Designs Enterprise

CurvFit (tm) is a curve fitting program 4 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/valleys data. CurvFit is an example of Calculus programming... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error). See comments in EX*.?
