While Rational Acoustics (the company founded by the creators of Smaart) currently supports newer versions, Smaart v6 paved the way for the sophisticated, high-resolution measurements found in and the Smaart Suite .

While more limited than modern versions, v6 improved the ability to manage multiple measurement signals, making it easier to compare different microphone positions.
The definitive characteristic of Smaart v6 was its ground-up architectural rewrite. Previous versions relied on legacy code tied tightly to Windows-specific audio drivers and protocols. Version 6 introduced:
While the industry has moved forward with modern editions like Smaart Suite (v9) , Smaart v6 remains a legendary tool known for its stability and the introduction of many features that are now standard in live sound optimization. Core Capabilities of Smaart v6 smaart v6 software
A: No. Smaart v6 is no longer sold. Current versions are available from Rational Acoustics (Smaart Suite, Smaart RT, Smaart LE, Smaart SPL). However, if you already own a v6 license, it will continue to run on a suitable computer (e.g., an old machine running Windows XP or Snow Leopard).
For single-channel analysis, v6 offered a robust RTA and a Spectrograph (waterfall plot). This allowed engineers to quickly identify feedback frequencies, analyze room resonance, and monitor environmental noise compliance. 3. Native Cross-Platform Compatibility
| Task | Method | Outcome | |------|--------|---------| | | Place an RTA mic 4 m in front of subs/tops; use transfer function with a “send Y” to the amplifier rack | Accurate amplitude, phase and coherence plots to confirm speaker processor settings | | Checking Microphone Responses | Position two microphones close together, capsules on‑axis, 10 feet from a speaker; use Auto‑Small to set delay | Immediate frequency response comparison; change the angle of the test mic to see off‑axis behavior – useful for predicting feedback frequencies | | Making Polar Plots | Place measurement mic 10 feet from speaker; play pink noise; capture spectrograph snapshots every 5° of rotation | A decent 2‑D polar plot across 360°, created without specialized hardware | | System Calibration | Use a piston microphone calibrator or an SPL meter as a reference | Accurate SPL calibration, essential for meeting noise regulations or aligning distributed systems | | Remote Control of DSP | Connect to supported equalizers and DSP processors over the control bus | Modify system tuning parameters directly from the Smaart interface, integrating measurement and control in one environment |
To perform dual-channel transfer function measurements in v6, you need a specific hardware chain: While Rational Acoustics (the company founded by the
One of Smaart v6’s most significant advances was its , which natively supported multi‑channel inputs via ASIO on Windows and Core Audio on Mac OS X .
Version 6 was resource-heavy upon release because of its new code rewrite. Today’s versions are highly optimized for multi-core CPUs.
Rational Acoustics’ current support policy follows a clear sunset schedule: when a new major version is released, older versions gradually move to lower tiers of support and eventually become “unsupported” products. For users who need a modern, fully supported analyzer, the current or Smaart RT are the recommended paths forward.
To understand the significance of Smaart v6, it is essential to look at its complex lineage. Smaart was originally created by SIA Software (Sound Technology Inc. and Jamie Anderson) and published by EAW (Eastern Acoustic Works). On the website, enter that ID to generate a keyfile
It is not guaranteed to work on modern operating systems like Windows 10/11 or recent macOS versions. Core Functionality
Smaart v6 software is designed for live sound engineers and audio professionals who need to analyze and optimize the performance of live sound systems. This includes:
This meant that engineers were no longer locked into expensive hardware. Suddenly, you could run on a generic Windows laptop with a multi-channel USB audio interface. This democratized system tuning. A small club engineer could afford the same transfer function accuracy that a stadium touring engineer used.
The GUI in version 6 was heavily praised for being more intuitive than its predecessors. The messy, colored memory-save buttons were replaced by a sleek, organized pop-up window, allowing for better data management and quicker workflow. 5. Multi-Session Capability
Provided a reliability index, showing how much of the measured signal was actually caused by the reference signal versus background noise or reflections. 2. Real-Time Analyzer (RTA) and Spectrograph
The Smaart v6 GUI was designed for speed and clarity. Its largely grayscale palette ensured good visibility even in dark indoor venues, with plot traces and bar graphs providing the majority of color.
