Using the WT3 Memories

The WT3 software features 20 user memories for saving your detailed measurements along with much other user entered information about the driver. Each memory consists of the impedance and phase plots, the test setup information (test box volume, added mass etc.) along with the three pages of parameters, ,specifications and comments that are seen at the Driver Editor. When you save a WT3 file (type ".wt3") to disc this measurement project file contains all the measurements in the projects 20 memories as well as the data currently on the Workbench.

Note: The most recently measured impedance plot is said to reside on the WT3 “Workbench.” This measurement is overwritten each time the analyzer is run. The Workbench is also overwritten when a memory is recalled or when data is imported. Once you have measured data you want to keep (even temporarily) save it to one of the 20 memories before proceeding with another measurement. All data in the 20 memories is saved with the WT3 project file. Multiple memories can be overlaid to allow for easy comparison of various measurements. Use the memory buttons in the Toolbar to show or hide various memories. After a memory has been recalled it can then be saved to a different memory. After a memory is recalled it is available to be exported to a .txt file.

All the commands related to memory operations can be found under the "View" menu. Here are the details of the memory commands. Note that each command has a keyboard shortcut that you may find more convenient than the menu command after you become familiar with the software.

View Menu: Save to Memory

These commands cause the plot on the Workbench to be saved to the selected Memory along with all the driver parameters.

From the keyboard, use Alt+1, Alt+2 etc. through Alt+0 to save to memories 1 through 10. Use Alt+Shift+1, 2 etc. through 0 to save to memories 10 through 20. For example, to save the current response to Memory 5 you would press and hold the Alt key and then press the 5 key.

View Menu: Show/Hide Memory

These commands alternately show and hide the selected memory.

•From the keyboard, use Ctrl+1, Ctrl+2 etc. through Ctrl+0 to show or hide memories 1 through 10

•Use Ctrl+Shift+1, 2 etc. through Ctrl+Shift+0 to show or hide memories 10 through 20

For example, to toggle the display of the response in Memory 5 you would press and hold the Ctrl key and then press the 5 key. Use Ctrl+W to toggle the display of the Workbench response. In addition to the menu and keyboard commands, you can also toggle each memory on or off at the Memory Toolbar.

WT3 specifications

The Dayton WT3 is a sophisticated and highly regarded tool in the field of audio measurement and analysis, particularly known for its precision in loudspeaker testing. This comprehensive device integrates several advanced features and technologies, making it an essential choice for audio professionals, engineers, and hobbyists alike.

One of the standout characteristics of the Dayton WT3 is its dual-channel capability, allowing users to conduct simultaneous measurements of two different loudspeakers. This feature is particularly useful in stereo systems where matching drivers is essential. The WT3 utilizes a high-resolution analog-to-digital converter (ADC) that ensures accurate and detailed frequency response measurements, providing users with the data they need to refine and optimize their audio setups.

The WT3 is equipped with a user-friendly interface that simplifies the measurement process. Its software is intuitive and runs on Windows, which means that users can easily navigate through various options to configure tests and analyze results. The inclusion of a built-in microphone makes it possible to perform room acoustics measurements, further enhancing its versatility.

Another key technology integrated into the Dayton WT3 is its frequency sweep capability. By generating continuous sine wave sweeps across a wide frequency range, the WT3 can analyze the response of loudspeakers in real-time. This allows for identifying resonances, distortion, and other critical parameters that affect sound quality.

The WT3 also features a range of measurement modes, including impedance measurements, which can be invaluable for understanding how a loudspeaker behaves across different frequencies. This data is displayed in easy-to-read graphs and charts, facilitating a straightforward interpretation of results.

Moreover, the Dayton WT3 utilizes advanced signal processing algorithms that help in reducing noise and other unwanted artifacts that can skew measurements. The device's accurate phase response measurement capability further distinguishes it from competitors, providing essential data for crossover design and speaker alignment.

In summary, the Dayton WT3 combines advanced measurement technology with an intuitive user experience, making it an essential tool for those seeking precise loudspeaker performance insights. Its features and capabilities position it as a valuable asset for both professional audio engineers and enthusiasts dedicated to achieving the best possible sound quality. Whether for designing new speakers or optimizing existing setups, the WT3 delivers reliable performance and accuracy.
