Visual Analyser version
A comprehensive professional real-time software suite that transforms your PC into a full set of measurement instruments, with no additional hardware required (you can use your PC’s sound card). Alternatively, you can use specific external hardware.
winget install --id=SillanumSoftware.VisualAnalyser -eDescription
VA is a real-time program that simulates a range of electronic instruments, including: - 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; - 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 plus resolution calculus; - Filtering (low pass, hi pass, band pass, band reject, notch, "diode", DC removal, graphic equalizer; - 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) )and display them with an internal viewer; - 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 in parallel with custom frequency response; - Support for 8/16/24 bit soundcard by means of API calls; - Internal 80 bit IEEE floating point variables for minimum rounding error; - Unlimited frequency sampling (depend from the capabilities of your soundcard/acquisition device); - 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/flac/mp3 file recording and playback; - Internal input; - Custom FIR filters; - Graphic equalizer; - Acquires audio samples from other applications; - Tool for automatic computation of frequency response of device (amplifier, louspeaker etc. for now only two simple methods, but soon MLS and ESS); - Automatic Check for new version of VA (main menu, help item).
Visual Analyser version is available through winget as package ID SillanumSoftware.VisualAnalyser, with version 25.78. Use the install command above to set it up on Windows without downloading a separate installer manually.
