Smaart v.8 vs Smaart Di2
With two versions of Smaart now available – v.8 and Di2 – you may be wondering which version is right for you.
The choice between Smaart v.8 and Smaart Di mainly rests on two factors: your intended application for Smaart and your comfort level with a complex measurement rig.
For a large percentage of Smaart users, the capabilities and feature set of Smaart Di encompass virtually everything needed from Smaart as a tool. The RTA, Spectrograph, Transfer Function (Magnitude, Phase and Coherence) and delay/live Impulse response measurement engines in Di provide all the measurement capabilities and power needed on a day-to- day basis. In many circumstances, a measurement setup need only be a straightforward, simple, two-channel configuration using only one microphone and making only one Transfer Function measurement at a time. Because Di can be quickly configured and everything can be controlled and monitored from the top level of the GUI, it is a quick & easy go-to tool for both experienced Smaart users as well as beginners.
If you are a beginner with Smaart and dual-channel FFT-based measurements in general, then it may be beneficial to begin your foray into the world of Smaart with Di. Without a doubt, Di is the less complex beast of the two versions to configure and operate – particularly when Di is used in tandem with a Smaart I-O interface. With only one measurement mode, only one two-channel engine, and all major spectrum and transfer function controls on the top level of the GUI at all times, there is a lot less to configure and manage, and a lot less information and data to keep track of. If you are a beginner to Smaart, this can have very tangible benefits for getting up and running, and staying out of the weeds. (It is important to note however, the complexity of the standard version is by no means an insurmountable obstacle for a beginner. If you are using v.8 with a simple measurement configuration, getting up and running on the standard version is still relatively easy to master.)
At the end of the day, the biggest point to consider here is you… the person using Smaart. Remember, you are the analyzer. This is a critical issue. Even if your computer and rig can handle the demands of a complex, multi-measurement configuration, your ability to get things done, read your data and make meaningful decisions based on that information all relies on your level of comfort and facility with that complexity. A huge amount of measurement data coming at you all at once may not be the right paradigm for some engineers. A simpler, more methodical, serial approach may work best for your system engineering process.
That said….. there are a few functional needs which would prohibit the use of Di:
1) If you need to make multiple simultaneous Transfer Function measurements or if you need to be able to view two live transfer functions at the same time, or live averages of those transfer functions then you need v.8. Smaart Di only has the ability to measure one Transfer Function at a time.
2) If need to make acoustic measurements, examine reverb times and structure, need to calculate specific intelligibility criterion (like STI, Clarity, T60, etc), then you need Smaart v.8. Those capabilities reside in Smaart v.8’s Impulse Response mode, and are not included in Di.
3) If you need to control or monitor SPL/Leq of more than 2 inputs at a time. Smaart Di only supports input monitoring or control of 2 inputs at a time.
By design, the data structure and much of the command and control paradigms are the same between both versions of Smaart, meaning users can very easily move back and forth between versions without having to learn an entire new program. New users may want to start with Smaart Di and then move to Smaart v.8 as the need to increase rig complexity arises. Experienced users may want to get a license of Smaart Di in addition to their v.8 for use in jobs where the demands of v.8’s multi-measurement, multi-mode complexity are not needed (or desired).
