Desktop RTA Description

DesktopRTA is a real-time sound analyser for your PC with many features only found in much more expensive sound analysis software. DesktopRTA provides accurate graphical feedback suitable for amateur hi-fi enthusiasts, A/V engineers / installers and electricians. DesktopRTA samples sounds from the input of your PC's sound card and then applies a Fourier Transformation to the samples to obtain a frequency spectrum. The result is an accurate representation of the sampled sound broken down into its frequency components. This version is a complete full screen PC version of our very successful PocketRTA program. Features 44Khz sampling allowing signals up to 22Khz to be measured Full screen dual channel FFT display Definable FFT size and sample frequency (Up to 32K samples) Single channel spectrograph Standard ANSI / IEC A and C weighting curves Automatic noise cancellation Automatic peak note / frequency and octave display Narrow band Linear and Logarithmic scalable displays Octave, 1/3 octave, 1/6 octave and 1/12 octave displays Transfer Mode for comparing amplitude and phase response SPL (Sound Pressure Level) display 250x zoom for accurate analysis of narrow band data Internal Signal Generator Touch screen plotting of nearest point with frequency and decibel readout Up to 64x averaging and smoothing to help stabilize the display Peak trace facility for better reading of fluctuating frequencies Selectable signal decay speeds Selectable signal gain control Pause facility freezes the live trace to aid analysis of data Trace capture facility ASCII Export of FFT's (Left and Right channels plus traces) Selectable Input channel
