Visual Analyzer Software

If you are looking for a FFT analysis software that will allow you to turn your PC into a full-featured measurement instrumentation, Visual Analyzer is the right tool for you!

The best part is that there is no need to install any additional or new hardware. 

You can simply use the sound card in your PC to start measuring sound.

With the Visual Analyzer, it is now even easier to analyze sound signals.

Besides, you don’t have to worry about licensing, since the program is already available for everyone.

Visual Analyzer is a highly recommended tool that offers a comprehensive range of sound analysis functions and is suitable for everyone, from audiophiles to engineers.

Use Visual Analyzer today to get a comprehensive picture of your analysis.

Oscilloscope (dual channel, xy, time division, trigger)

Spectrum Analyzer with amplitude and phase display (linear, log, lines, bar, octaves band analysis 1/3, 1/6, 1/9, 1/12, 1/24)

Wave-form generator with “custom functions”, triangular, square, sinusoidal (all with NO ALIASING and smooth transition), white / pink noise, pulse generation, DC generation [New!]

Frequency meter (in time and frequency domain) and counter; in time domain by means of a real time zero crossing algorithm

Volt meter with DC  [New!], True RMS, peak to peak and mean display plus resolution calculation

Filtering (low pass, hi pass, band pass, band reject, notch, “diode”, DC removal)

Memo windows (data log) for analysis and storage of time series, spectrum and phase with “triggering” events; THD and Impedance data logging with spline interpolation; possibility to save the graphics in various format (.tee, .txt, .wmf)

Screenshot of Spectrum and Scope window

A TRUE software digital analog conversion (for complete signal reconstruction using Nyquist theorem)

Frequency compensation: possibility to create / edit a custom frequency response and add it to the spectrum analyzer computed spectrum; added standard weighting curves A, B, C [New!] in parallel with custom frequency response function FRF

Support for 8/16/24 bit soundcard by means of API calls

Internal 80 bit IEEE floating point variables for minimum rounding error

Cepstrum analysis , cross correlation

Extended THD measurements, with automatic sweep, compensation, data log

ZRLC meter with vector scope, automatic sweep in time and frequency for automatic measurement

Calibration mechanism (you can calibrate the VA scales directly in VOLT or dB or percent full scale)

Set of values computed in real time (peak to peak, peak, crest factor, form factor, true rms, mean, frequency with zero-crossing algorithm)

Wave file recording and playback

Custom FIR filters
