Smaart v.6

Smaart is the most straightforward and widely used software for real-time sound system measurement, optimization and control.
Smaart v.6 performs dual-channel, FFT-based audio measurement in an intuitive, accessible interface that seamlessly integrates measurement, analysis, and data logging. It can also remotely control an extensive, constantly expanding list of professional equalizers and DSP processors.
Smaart v.6 now runs native under both Mac OS X and Windows from the same unified source code. (not tested...)

Support for ASIO Multi-Channel Input Devices
Smaart v.6 can receive multi-channel inputs via ASIO under Windows or Core Audio on Mac OS X, enabling selection of measurement signals from a multi-channel device within Smaart. This new data acquisition module opens up a vast array of multi-channel audio devices now available on the market, such as the Mackie Onyx 800F FireWire preamp. It also greatly simplifies the hardware setup requirements for operating a multi-microphone Smaart measurement rig.

New Real-Time Measurement Mode
All Smaart real-time measurements (RTA, Spectrograph, Transfer Function (magnitude and phase), and Impulse Response now run concurrently, and any two measurements can be viewed simultaneously. The result is the ability to run hybrid measurement modes that display real-time Spectrum and Frequency Response data at the same time. This platform allows operators to significantly expand the way they measure and address their sound systems.

* Two-Channel RTA: Selectable linear or fractional octave banding (down to 1/24th octave resolution), peak-hold, THD calculation, user-defined timed averaging, and standard Noise Criterion curves (when calibrated for SPL measurement).
* Single-Channel Spectrograph: 3-D display of a signal’s spectral content over time helps identify feedback frequencies, system resonances, and mechanical noise.
* Frequency Response Magnitude & Coherence: Measurements down to 1/24th octave resolution of system magnitude response with comprehensive rms and vector averaging functionality and a corresponding Coherence measurement indicating data quality/stability.
* Phase Response: Measurements down to 1/24th octave resolution of system phase response.

Enhanced Impulse Response Mode
Impulse Response Mode now operates in its own window that runs independently of real-time Spectrum and Transfer Function measurements. The Impulse Response Mode has also been expanded to include intuitive tools for analyzing and dissecting IR measurements on the fly, such as a user-specified time window function for retrieving frequency domain data from specific portions of an impulse response.

Expanded Signal Generator Functionality
Smaart v.6 adds triggered swept sine waves for impulse response measurements to its standard list of generator signals and functions. The triggered swept sine functionality operates with the FFT length-specific, synchronized measurement sources, and enables the user to do traditional laboratory and QC measurements.

Object-Oriented, Multi-Threaded Program Architecture
Multiple sessions of Smaart can now run simultaneously, allowing for the integration of multiple simultaneous system measurements in later releases. A new API (Application Programming Interface) allows other software programs – even third party programs such as Dolby Lake - to import Smaart data and control the Smaart measurement engines remotely. And, with code base portability, Smaart’s measurement engines are now separate code “objects” that can be integrated into other EAW/LOUD Technologies products such as the SPL meter on the new EAW UMX.96 digital mixing console.
