Features Summary
SmaartLive, SIA Software Company’s dual-channel FFT-based audio measurement software, is the professional audio industry standard for real-time sound system measurement, optimization, and control. SIA’s SmaartLive software combines several powerful audio frequency measurement and analysis tools.
The Spectrum mode RTA display functions as an FFT-based real-time spectrum analyzer. This display plots the spectrum (magnitude values by frequency) of the measurement channel sound card input.
The RTA plot puts magnitude on the (vertical) y-axis and frequency on the (horizontal) x-axis. When the RTA display is active, time-domain audio data from the A/D converter of your sound hardware is continuously transformed into the frequency domain using a mathematical technique called the Fast Fourier Transform (FFT). The FFT data can be plotted on the RTA display in real time, processed into octave or fractional-octave bands. The magnitude for each frequency band (or data point) on each of the two input channels is updated several times per second.
The SmaartLive Spectrograph is a second type of RTA display that provides a way of looking at the frequency content of an input signal over a period of time. Instead of showing you the results of only one FFT measurement at a time (whether averaged or instantaneous), as is the case on the RTA display, the Spectrograph displays a record of the most recent 100 frames or more.
The Spectrograph display effectively shows you three-dimensional data (time, frequency and energy) on a two-dimensional plot with time on the y axis, frequency on the x axis and magnitude represented by color. The relationship between color and magnitude value is determined by the magnitude range currently specified, the number of colors used, and the selected start and end colors.
SmaartLive’s real-time Transfer Function measurement capability is an extremely useful tool for setting up sound system equalizers and crossovers. A transfer function is a mathematical comparison of complex FFT data from two signals — typically the input and output of a device or system under test. SmaartLive uses this calculation to determine how one signal differs from the other.
By comparing the signal going into a device or system to what comes out, SmaartLive can calculate its frequency (magnitude and phase) response very precisely. A major advantage of this dual-channel approach is that it works with a wide variety of test signals, including music or other recognizable program material.
In Transfer Function mode, SmaartLive performs FFT calculations using audio data from the two inputs of your sound hardware and compares the two sets of FFT data to display a single trace showing the relative magnitude difference between the two signals.
