Vertical scale calibrated as fraction of digital full scale ('FS') with currently-set mixer-settings etc.Implemented correct 'A'-weighted displays (rather than Fletcher-Munson/Terhardt).Choice of linear and logarithmic (dB) vertical scales (including 'perceptual' A-weighted scales).User-selection of different FFT transform sizes to trade-off time response and spectral resolution.Spectrum obtained using FFT with Hanning (raised-cosine) window-function.Supports multiple 'wave input' devices (multiple soundcards, and/or the newer Windows Vista/7 sound model).User selection of sampling-rates, including 32kHz, 44.1kHz, 48kHz.Stereo input, dual bargraph, choice of Left, Right, sum or difference for frequency analysis.Bargraph peak-level indicator shows time-domain peak levels and onset of clipping distortion (spectrum also goes red).Samples an audio stream in 16-bit stereo, then uses a Fast Fourier Transform to yield the spectral analysis in real time.Runs under Microsoft Windows 95, Windows XP, Windows Vista, Windows 7 and newer.Acoustic noise analysis and RD into making quieter appliances.Understanding audio quality and the effects of digital compression (e.g.It uses fast Fourier transform (FFT) to give a real-time ('live') spectrum display on your screen.

Spek – Acoustic Spectrum Analyser Download News Contribute The response of any system you now insert in the test loop can now be measured very precisely plus or minus. Note that the response of the sound card has been removed from the measurement so that a self test of the sound card now shows a flat response. TrueRTA Quick Sweep WITHOUT Sound Card Calibration (self test of E-MU 0404, dark gray background)īelow is TrueRTA with Sound System Calibration switched on. Below is the measured response of an E-MU 0404 USB audio interface at 96 kHz sampling frequency. TrueRTA's Quick Sweep employs a short digitally generated sweep (chirp) to measure the frequency response of electronic and acoustical systems.
