Visual Analyser is a handy application designed to display in real time the sound analysis of a source connected to the computer. It provides a set of instruments that allow you to test a recording device. You can use an oscilloscope, a spectrum analyzer and a wave form generator without having any hardware attached to your computer.

Detailed Features about:

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, sinus, white noise and pulse generation (NO ALIASING);

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, true RMS, peak to peak and mean display;

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; possibility to save in various formats and display them with a viewer;

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

Frequency compensation: one can create/edit a custom frequency response and add it to the spectrum analyzer spectrum ; added standard weighting curves A,B,C in parallel with custom frequency response;

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

Unlimited frequency sampling (depend from the capabilities of your soundcard);

Cepstrum analysis;

Cross Correlation;

Extended THD measurements, with automatic sweep and compensation.

ZRLC-meter with Vector scope, automatic sweep in time and frequency for automatic measurement.
