Measurement and Application

Averaging depth values in the real time mode of Smaart Suite, as well as RT and LE editions, use the number 1 through 10 to indicate an ascending order of less to more averaging. - Less averaging = more responsiveness, more vulnerable to noise, less stability. - More averaging = more stable, better noise rejection, less responsive. Where settings 1-3 are FIFO averages, 4-10 are weighted variable averaging (like an S curve where time constants are shorter in the HF than the LF). T...

What is SyncSource™ Transfer Function? ------------------------- A hallmark of the transfer function measurement process embodied in Smaart is the ability to measure a system’s response using whatever random signal is passing through it, commonly known as "Source Independent Measurement". This allows engineers to measure their systems under actual use conditions, with signals like speech and music, allowing for simultaneous listening evaluation. Moreover, it allows engineers to measure syste...

Third-Party Integration Support for Smaart v9 ------------------------- The following third-party applications are compatible with the Smaart 9 platform: Third-Party Integration Current Status Minimum Required Version FIR Designer & Designer M Compatible Designer - v3.5 Designer M - v2.6 Lake Controller Mostly Compatible (some known issues) v7.1.2 Waves TRACT Update In Progress TBD For any support regarding Smaart integration in the above...

Audient® EVO Control Integration in Smaart v9 ------------------------- Smaart v9.1 includes integrated gain and phantom power control for the Audient EVO® series interfaces (https://www.rationalacoustics.com/collections/audio-interfaces?filter.v.price.gte=&filter.v.price.lte=&filter.p.vendor=Audient&sort_by=best-selling). Roland® OctaCapture and Smaart IO users will already be familiar with these controls from those devices -- Smaart’s Input Meters view (View > Input Meters or [Shift] + ...

Is the Smaart IO compatible with the Smaart 9 platform? ------------------------- Yes, though it is now treated as a generic controllable audio interface, like the Roland Octacapture. You can control gain and phantom power natively within Smaart (View > Input Meters, or default hotkey Shift + E), however microphone sensitivity-based calibration and saving of microphones is no longer supported. SPL calibration must be done manually using a tone generator/calibrator, such as the iSEMcon SC...

Can I transfer my saved configuration to another device, operating system, or version/edition of Smaart? ------------------------- Short answer: No While you can save your current settings to a configuration file to be recalled later, this file cannot be reliably transferred between devices or across operating systems. Some of the settings that are saved contain environment-specific variables relating to the system that Smaart is installed on (i.e. exact directory paths). Loading a sav...

Can I transfer a captured trace from v8/Di v2 to v9? ------------------------- Short answer: Sort of* Smaart will not do this automatically, you will have to manually import the trace into the Smaart 9 platform (Suite, RT, LE, and SPL). There are two ways to do this: 1) Locate where the v8/Di v2 trace is saved. By default, Smaart will save traces to the following location (you can also right-click the trace and select "Open file location"): Windows - C:\Users\<your_username>\Docu...

Which interfaces have Control Integration and Gain Tracking within Smaart? ------------------------- Smaart can control the gain and phantom power of certain audio recording devices directly from within the "Input Meters" view. To access Input Meters, navigate to the View menu in the top menu bar of the program and select View > Input Meters, or use the Hot Key combo [Shift] + [E]. Devices with control integration will also allow for Gain Tracking, which is enabled in the Input Configu...

The RTA 420 is "pin 3 hot"; what does that mean? ------------------------- The Rational Acoustics RTA 420 microphone (listed on our store here (https://www.rationalacoustics.com/products/ra-rta-420)) is Pin 3 hot. This means that the polarity of the microphone is reversed compared to other microphone standards. If you are using a single microphone, this should not cause any differences in your measurement. However, if you will be comparing a microphone that is not pin 3 hot to the RTA 420,...
