The Desktop RTA Real Time Sound Analyzer from 4 Pockets is a real time sound analyzer for your compatible Windows computer. It provides multiple modes of graphical feedback for audio, including displays for linear, logarithmic, phase, peak, SPL, and spectrograph data, amongst others. The software supports sample rates up to 44.1kHz and features an integrated signal generator as well as automatic noise cancellation mode. Desktop RTA is capable of up to 250x zoom, allowing you to analyze narrow band data clearly.
Linear and Logarithmic Displays
DesktopRTA allows display of both Logarithmic and Linear frequency response. It has the ability to display two simultaneous traces, one for the left channel and one for the right channel of the input signal. This is useful for monitoring stereo signals or if you want to compare input data against a known test signal
The Transfer and Phase Display
The phase display can be used in conjunction with the transfer display and shows the phase shift, or time difference in the measurement signal relative to the reference signal for each frequency
A Spectrograph is a 3D representation of frequency/amplitude over time often used for analyzing speech
Octave and Sub Octave Display Modes
These modes are similar to those found on a conventional spectrum analyzer. This display breaks the frequency spectrum into ISO standard spaced bands
DesktopRTA has the ability to capture and display up to 3 static traces for use with comparing input signals. Traces can be exported to SDF format for use in other PC applications
44 kHz sampling allowing signals up to 22 kHz 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)
