AutoSignal 1.7 (Demo, $799.00)

AutoSignal is the first and only program that completely automates the process of analyzing signals. It gives researchers the power to rapidly find components of complex signals that normally require extensive programming and mathematical routines. It takes full advantage of its graphical user intuitive interface to simplify every aspect of operation, from data import to output of results.

DPlot 1.971 (Shareware, $32.00)

DPlot is a general purpose plotting program designed for scientists, engineers, and students. It features multiple scaling types, including linear, logarithmic, and probability scales, as well as several special purpose graphs: tripartite grids (shock spectra), grain size distribution plots, polar plots, contour plots of 3D data, and box-and-whisker plots and dot graphs of one or more 1D samples. Manipulation functions include FFT, filtering, and smoothing. Data can be input via a variety of file formats, copied from the clipboard, sent to DPlot from another program via dynamic data exchange, or generated by formula. Source code for example Visual Basic and C demo driver programs are included.

DSSF3 Full system Version 5.0.5.5 (Shareware, $660.00)

Various sound measurement can be performed using a various functions in the realtime analyzer. The FFT analyzer with the data record and the export function, the distortion analyzer, and the phase meter enable various measurement.

Frequency Analyzer 2.0 (Freeware)

Whistle a melody and watch this program graph the pitch in real time. The Frequency Analyzer technically speaking performs a Fast Fourier Transform of the sound. What it means is that it analyzes your voice and splits it into its component frequencies. Watch patterns of speech, the harmonics of vowels and the noise of sibilants. The size of the program is only 64k!

OscilloMeter 4.14 (Shareware, $399)

Oscillometer is intended for real-time investigation of data accepted from any ADC you will want. Oscillometer consists of an oscilloscope and FFT spectrum analyzer. Maximum numbers of channels, sampling frequency, bit rate of data, frequencies range, precision are limited only by type of used ADC. The obtained data and images can be saved to files or clipboard. Oscilloscope modes (for dual-channel ADC): original signals, sum, difference, dependence of one channel on another, amplitude distribution of input signals. The synchronization is independent in each of panel. Spectrum analyzer works on algorithm of Fast Fourier transform (FFT). The size of the block a FFT is up to 2^20 (1 M) samples of an input signal. The processing of overlapped in time series of samples of an input signal for combination of high resolution of the analysis on time and on frequency simultaneously. Smoothing windows (weighing an input signal) - more than 50 types. Averaging of results of some FFT: equally weighted - scalar or vector;

OscilloMeter - Spectrum Analyzer 4.14 (Shareware, $399.00)

The OscilloScope + FFT Spectrum Analyzer for real-time investigation of data accepted from any ADC you will want. Maximum number of channels, sampling frequency, bit rate of data are limited only by type of used ADC. FFT results analysis is realized in real-time mode. Fully functional demo works with ADC of sound card.

Phone Tone Decoder 1.5 (Shareware, $89.00)

PhoneTone Decoder is the programming component for beginning to advanced developers. Component Features Decode DTMF from wave file or wave stream or wave/in devices. Monitor Custom Tones from ... Decode FSK Caller-ID from... Decode TTY/TDD Baudot code from... Detect the custom tone signal from... Convert wave-form to spectrum from... ... Demo samples for VB and Delphi are available.

RAL / Realtime Analyzer Light 2.0.0 (Shareware, $24)

This is the latest version as of January 2003. This version program includes all features the DSSF3 has as of January 30, 2003. (The DSSF3 is our best sound measurement/analysis software and has been frequently updated.)Quality sound measurement software equivalent to at least US$10,000 hardware.The software license of RAL costs just US$24, but RAL is more functional than the usual FFT analyzer. General realtime measurement function is entirely included.
