: You can select a specific time range by dragging sliders on the history graph, allowing for "deep reports" on specific segments of an event. Comprehensive Manuals & Learning Resources
With Smaart v9, Rational Acoustics has completely overhauled their documentation, and the result is arguably the most significant "feature" of the new release. Here is why the Smaart 9 manual is genuinely better: smaart 9 manual better
One of the most significant improvements in Smaart 9 is the revised manual. The Smaart 9 manual is an exhaustive guide that covers everything from basic setup and configuration to advanced features and techniques. The manual is organized into several sections, including: : You can select a specific time range
By default, the spectrograph shows 20Hz-20kHz. Change this to 20Hz-10kHz immediately. The manual doesn't tell you that the top octave (10k-20k) is almost always irrelevant for system tuning and just adds visual noise. Zoom in on the speech frequencies (100Hz-8kHz) for a "better" view. The Smaart 9 manual is an exhaustive guide
Each workflow includes expected results, troubleshooting tips ("What if the phase trace slopes downward? Your delay is too long or too short."), and references back to the theoretical principles.
Smaart 9 automatically calculates delay, but for Phase measurements, you need to tell the software the inherent latency of your interface (convertor delay).
The official manual assumes you already understand acoustical theory. It will tell you how to enable the "Magnitude" trace, but it won't tell you why a 6dB/octave slope indicates a minimum-phase system. This is the gap we need to fill.
