Run as many simultaneous RTA and Transfer Function engines as your computer hardware can handle. You can view eight microphones placed across an arena all at once.
Visualizes the frequency response of an incoming signal using fractional-octave banding (up to 1/48th octave). It shows the energy distribution across the audible spectrum.
By comparing these two signals in real time, Smaart calculates exactly how a sound system and the room acoustics are altering the audio. This allows engineers to view precise frequency response, phase relationships, time arrivals, and intelligibility metrics. Core Measurement Modes in the Full Version
Smaart Live is a professional audio analysis and metering software widely used in live sound, installation, and broadcast applications. A very useful feature in Smaart Live for ensuring high-quality audio and for troubleshooting audio issues is the . Smaart Live Full- Version
: A powerful sound level measurement and logging toolset. It provides real-time dB levels to ensure audience safety and compliance with noise regulations, with features like customizable LEQ metrics and remote viewing via a web browser. Key Features of Smaart v9 Suite
A high-quality, low-latency USB or networked (Dante/AVB) interface. It must feature at least two inputs and support transparent preamps.
Smaart operates primarily through three distinct engines tailored to specific diagnostic tasks. 1. Real-Time Mode (RTA and Spectrograph) Run as many simultaneous RTA and Transfer Function
Used to calculate proper delay times between main speakers and fills, find early reflections, and calculate speech intelligibility metrics like STI or reverberation times ( T60cap T sub 60 Essential Hardware Requirements
Pro Tip: The Full Version allows you to apply "Delay Finders" and auto-smoothing. Use the "Vector Delay" tool to find the exact propagation delay between your subs and tops.
Is that expensive? Compared to a $20 phone app, yes. Compared to a $5,000 line array box? No. It shows the energy distribution across the audible spectrum
Allows simultaneous viewing of the impulse response in real-time alongside transfer function measurements. 2. Impulse Response Mode (IR) Used for deep analysis of time-domain data, including: Time-of-flight measurements for speaker alignment. Reverberation time (RT₆₀) calculations.
Timing information used for aligning subwoofers and crossovers. Coherence:
More importantly, pirated audio software often suffers from internal clocking glitches and buffer corruptions. In a measurement tool, a subtle software bug can result in corrupted phase curves or false EQ data, leading you to misalign a sound system and potentially damage expensive venue loudspeakers. Always purchase a legitimate license or download the official, unrestricted 30-day trial directly from Rational Acoustics. Conclusion
Smaart Suite allows you to switch between Real-Time, Impulse Response, and SPL modes seamlessly. The interface uses tabbed workspaces, allowing an engineer to have a Spectrum (RTA) tab open, a Transfer Function tab for system tuning, and an SPL log running simultaneously. 3. Dual-Channel FFT Analysis
Smaart includes a built-in generator capable of producing pink noise, pink sweep, white noise, and sine waves, eliminating the need for external noise injection hardware.
