Rational Acoustics Smaart V7.2.1.1: A Powerful Tool for Sound System Measurement and Optimization
Rational Acoustics Smaart V7.2.1.1 is a software platform that enables users to perform real-time sound system measurement, analysis and optimization. It is designed for professional audio engineers, sound technicians, acousticians and researchers who need to measure and optimize the performance of sound systems in various environments.
Smaart V7.2.1.1 is the latest version of the software, released in June 2011 by Rational Acoustics, a company that specializes in acoustic test and measurement software and hardware products. It is available for both Windows and Mac OS X operating systems, and supports ASIO, Wav and CoreAudio input devices.
Some of the key features of Smaart V7.2.1.1 are:
- It can run multiple, simultaneous single-channel (spectrum) and dual-channel (transfer function) measurement engines, allowing users to analyze different aspects of the sound system at the same time.
- It has a new object-oriented program architecture that makes it more flexible, scalable and compatible with future developments and applications.
- It has enhanced and improved measurement engines that offer more accuracy, stability and functionality than previous versions.
- It has a simpler and friendlier user interface that reduces unnecessary clutter and provides more intuitive controls.
- It has a new data acquisition module that provides increased and improved access to the devices and signals in the system.
- It has a real-time mode that includes four core FFT-based measurement capabilities: RTA (Real-Time Analyzer), Spectrograph, Transfer Function and Live Impulse Response.
Smaart V7.2.1.1 is a powerful tool that can help users to measure and optimize the frequency response, phase response, impulse response, coherence, distortion, delay, level and SPL of sound systems in various settings, such as live concerts, studios, theaters, churches, stadiums, auditoriums and classrooms.
To download Rational Acoustics Smaart V7.2.1.1 for Windows or Mac OS X, users can visit the official website of Rational Acoustics[^2^] or use a torrent file[^1^] [^3^]. However, users should be aware that downloading software from unauthorized sources may pose risks of malware infection or legal issues.
One of the main advantages of Smaart V7.2.1.1 is that it can run multiple measurement engines at the same time, allowing users to compare and contrast different aspects of the sound system. For example, users can run a spectrum engine to monitor the frequency content of the input signal, a transfer function engine to measure the frequency and phase response of the system, and a live impulse response engine to measure the time domain characteristics of the system. Users can also configure each engine with different settings, such as FFT size, averaging, weighting, smoothing and windowing.
Another advantage of Smaart V7.2.1.1 is that it has a new object-oriented program architecture that makes it more flexible and scalable. Users can create and manage multiple measurement objects, such as inputs, outputs, engines and traces, and assign them to different tabs or windows. Users can also customize the layout and appearance of each tab or window, and save and recall them as presets. Moreover, the new architecture enables Smaart to interact with other applications and devices, such as remote GUIs, data export/sharing tools and plug-in versions.
A third advantage of Smaart V7.2.1.1 is that it has enhanced and improved measurement engines that offer more accuracy, stability and functionality than previous versions. For example, the spectrum engine has a new fractional octave banding option that allows users to adjust the resolution of the RTA display. The transfer function engine has a new coherence blanking option that allows users to filter out low-coherence data from the magnitude and phase plots. The live impulse response engine has a new time domain filtering option that allows users to apply high-pass, low-pass or band-pass filters to the input signal before measuring the impulse response.
