In this article, we will give you an overview of Smaart v.7.4 23, its features, benefits, and how to use it effectively. We will also show you how to upgrade your Smaart v7 license to the current 7.4 release for free.

What is Smaart v.7.4 23?

Smaart v.7.4 23 is the latest update of Smaart v7, the most powerful and versatile version of Smaart ever released. Smaart v7 is a dual-platform (Mac & PC), multi-channel, multi-mode audio analysis software that enables you to measure and analyze sound in real time.

Smaart v.7.4 23 introduces several new features and improvements, such as:

A new licensing and activation procedure that allows you to manage your license online and activate it on up to three computers.

A new SPL meter that displays the sound pressure level in various formats and integrates with external SPL loggers.

A new Live IR mode that allows you to capture and display impulse responses in real time.

A new Delay Finder that automatically calculates the delay time between two signals.

A new Data Library that stores and organizes your measurement data.

A new API that allows you to control Smaart remotely from other applications or devices.

And many more bug fixes and enhancements.

Why should you use Smaart v.7.4 23?

Smaart v.7.4 23 is a must-have tool for any audio engineer who wants to optimize their sound system performance and troubleshoot any acoustic issues. With Smaart v.7.4 23, you can:

Measure the frequency response, phase response, coherence, impulse response, and transfer function of your system.

Identify and correct any frequency or phase anomalies, such as comb filtering, feedback, resonance, or cancellation.

Align your speakers and subs using delay, polarity, and level adjustments.

Monitor the SPL and dynamic range of your system and comply with noise regulations.

Compare different systems or configurations using overlays and snapshots.

And much more.

Smaart v.7.4 23 is compatible with any audio interface that supports ASIO or Core Audio drivers, and can work with up to 32 input channels simultaneously. You can also use external microphones or measurement devices with Smaart v.7.4 23, such as RTA mics, SPL meters, or accelerometers.

How to upgrade to Smaart v.7.4 23?

If you already have a Smaart v7 license, you can upgrade to Smaart v.7.4 23 for free. Here are the steps to do so:

Download the Smaart v.7.4 23 installer from the Rational Acoustics website.

Run the installer and follow the instructions to install Smaart v.7.4 23 on your computer.

Launch Smaart v.7.4 23 and agree to the end-user license agreement.

Enter your Smaart v7 license code and click on \"Activate\".

Deactivate your old Smaart v7 installation from your computer and from the Rational Acoustics web server.

Enjoy using Smaart v.7.4 23!

If you don't have a Smaart v7 license, you can purchase one from the Rational Acoustics website or from an authorized dealer. You can also download a free 30-day trial version of Smaart v.7.4 23 from the website.

How to use the SPL meter?

The SPL meter is a new feature in Smaart v.7.4 23 that allows you to display and monitor the sound pressure level of your system in various formats and integrate with external SPL loggers. To use the SPL meter, you need to:

Make sure your input is calibrated as described in the previous section.

Select SPL Mode from the radio buttons in the upper right corner of the interface (if you are using Smaart Suite).

Select Show Meter Grid Config from the SPL control bar and use the menu in the upper right of the new SPL meter window to add, remove, or edit meters.

For each meter, you can choose the input source, the weighting (A, C, or Z), the time constant (Fast, Slow, or Impulse), and the Leq interval (from 1 second to 24 hours).

You can also select a reference curve (such as NC or NR) and a threshold level for each meter.

You can drag and resize the meters as you wish, and lock them in place by selecting Lock Meter Grid Config from the SPL control bar.

You can view the SPL history of each meter by selecting Show History Graphs from the SPL control bar. You can zoom and scroll the graphs using your mouse or trackpad.

You can log your SPL data to a CSV file by selecting Start Logging from the SPL control bar. You can choose the logging interval and the file name and location.

You can also integrate Smaart with external SPL loggers, such as 10EaZy or NTi XL2, by selecting Connect to External Logger from the SPL control bar. You can choose the logger type and IP address, and view its data in Smaart.

For more information on how to use the SPL meter, please refer to the documentation or watch these videos .

How to use the Live IR mode?

The Live IR mode is a new feature in Smaart v.7.4 23 that allows you to capture and display impulse responses in real time. Impulse responses are useful for measuring the acoustic characteristics of a room or a system, such as reverberation time, frequency response, and phase response. To use the Live IR mode, you need to:

Make sure your input is calibrated as described in the previous section.

Select Live IR Mode from the radio buttons in the upper right corner of the interface (if you are using Smaart Suite).

Select Show Live IR Config from the Live IR control bar and use the menu in the upper right of the new Live IR window to add, remove, or edit Live IRs.

For each Live IR, you can choose the input source, the reference source (if using a dual-channel measurement), the trigger type (manual or automatic), and the capture length (from 0.1 to 10 seconds).

You can also select a weighting (A, C, or Z) and a window type (rectangular, Hann, or Blackman-Harris) for each Live IR.

You can drag and resize the Live IRs as you wish, and lock them in place by selecting Lock Live IR Config from the Live IR control bar.

You can view the impulse response, frequency response, phase response, and energy time curve of each Live IR by selecting Show Live IR Graphs from the Live IR control bar. You can zoom and scroll the graphs using your mouse or trackpad.

You can also view the reverberation time (RT60) of each Live IR by selecting Show RT60 Graphs from the Live IR control bar. You can choose between T10, T20, T30, or EDT methods for calculating RT60.

To capture an impulse response, you need to generate an impulse signal using a loudspeaker. You can use a balloon pop, a starter pistol, a clap, or a sweep signal as an impulse source. Make sure your microphone is placed at the desired measurement position.

If you are using a manual trigger, press the Capture button on the Live IR window when you generate the impulse signal. If you are using an automatic trigger, Smaart will detect the impulse signal and capture it automatically.
