Oleg Ya. Shmelyoff - Software Products

Two-channel multi-tone audio frequency sinusoidal signal generator is intended for adjusting and measuring parameters of audio equipment. Works with 16, 24 and 32 bit sound cards at sampling rate up to 384 kHz. Independent channels frequency and amplitude controls. Adjustable phase shift between channels. Up to eight oscillators per channel with separate frequency and level setting. A step of frequency setting is 0.00001 %; level - 0.001 dB; phase - 0.001 degree. The minimum coefficient of nonlinear and intermodulation distortion, precision, stability and range of frequency are limited only by quality of the used sound card. The Sweep Frequency Mode with adjustable rate in linear or logarithmic scale. Multi Oscillators Sweep Frequency Mode. Generation of noise: white, pink (1/f), Brownian (1/f^2). Mode of amplitude modulation of one channel by another. Real time signal synthesis. Recording of synthesized signals to hard disk. The demo is completely functional, but the time of sounding is limited to 15 seconds after each clicking of the "Start" button. The registration removes demonstration limitation.

OscilloMeter - Spectrum Analyzer

Oscillometer is intended for real-time investigation of data accepted from sound card or other 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. Spectral analyzer works on algorithm of Fast Fourier transform (FFT). Spectrum analysis frequency resolution is up to 524288 bins. 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.
