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; exponentially weighted - scalar. Number of averaging transforms is from 2 up to 20 or infinite. Synchronization of the spectrum analyzer is independent from oscilloscope. The following parameters can be measured in real time mode: Peak Frequency, Peak Amplitude, Total Power, Signal to Noise Ratio (SNR), Signal to Noise plus Distortion Ratio (SINAD), Spurious-Free Dynamic Range (SFDR), Effective Number Of Bits (ENOB), Total Harmonic Distortion (THD), Inter-Modulation Distortion (IMD), Direct Current Offset, Peak Phase Difference. Holding or decaying maximum values of spectra. The Demo version is a fully functional copy of OscilloMeter with the exception that input time is limited to 15 seconds after each "Start" button click. The registration removes demonstration limitation.

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.
AutoRegressive linear models offer robust models that can quickly handle smaller data sets that FFT cannot accurately analyse. With AutoSignal, you can also recover signal components based on power - the component may be sinusoidal, a square wave, a sawtooth or anharmonic pattern. It lets you see a complete picture of the frequency space using the library of six Fourier Spectrum methods with total flexibility. It gives you a choice of three adjustable mother wavelets: Morlet, Paul and Gaussian Derivative - in both real and complex forms to optimise localisation results.
Scientists and engineers can perform complex signal analysis without programming by selecting menu items that determine how the computer will analyze and present data. Selecting a processing step or algorithm causes the software to provide further menus or windows so users can tailor performance to their needs. After the user makes a processing selection, the software immediately presents processing results in 2-D or 3-D views
Built-in spectral analysis procedures include :
FFT
AutoRegressive
Moving Average
ARMA
Complex exponential modeling
Minimum variance methods
Eigen analysis frequency estimation and Wavelets
AutoSignal consists of many important leading edge signal analysis, filtration, prediction, and noise removal technologies.

Voxformer is a multi-functional vocal channel strip plug-in in PC VST
format. Combining several professional quality processing modules, Voxformer
was designed to be a comprehensive solution for all your vocal processing
needs - be it a spoken or a sung vocal performance.
The coolest feature of Voxformer is its one-knob vocal compressor.
Using only a single knob you can get a tight, open and definitive
professional vocal sound in no time. You do not have to worry about
common ratio, release, attack and make-up gain controls since they are
automatically selected by the advanced compression algorithm. Moreover,
Voxformer features two compressors of this type allowing you to apply either a
two-band or a two-stage (serial) vocal compression. For two-band compression
Voxformer splits the audio signal into two spectral parts, by means of a
switchable crossover filter.
Voxformer also features a de-esser with switchable center frequency,
threshold and ratio. Noise gate is also available. This noise gate--in a
manner similar to a compressor--was designed to bring the easiness of tuning
while providing excellent sonic results. For those who like the saturated
vocal sound Voxformer implements a special saturation module which applies a
smooth vintage saturation. Another useful thing Voxformer has to offer is the
presence boosting module which you can use to add some shine and space to the
vocals.
To simplify the control over these processing modules Voxformer implements
residue listening which allows you to hear what gets removed during de-essing
and noise gate operation, and what is being added by the presence module.
As a finishing touch, Voxformer offers you a flexible 4-band equalizer
(pre/post selectable) with a real-time output stage fast Fourier transform
(FFT) spectrum analyzer display. Each equalizer band can be switched to a
parametric, low-shelf, high-shelf, low-pass or a high-pass filtering mode.
