Granular Audio objects 

AudioworX contains 39 basic audio objects where each object can operate in multiple modes of operations, thereby keeping lesser objects and more functionality.  AudioworX contains many advanced audio features which can be licensed by the customer. Contact support email for advanced audio features and audio objects.

For more details on available audio objects, refer to the Audio Object Description Overview

Parameter Sets /Master Preset Controller

This feature enables the acoustic engineers to create presets that can be changed depending on the run time mode of the system.

Key Features

    • Enables users to create presets and sub-presets by choosing audio object parameters from Multiple instances or core.
    • Enables users to create a slot from multiple presets. (Slot is a collection of presets).
    • Enables users to switch between slots by choosing multiple ramping methodologies to achieve desired audio performance.

For more details about Parameter Sets, refer to the below topics.

Panel Designer 

Panel Designer provides an ability to quickly design the Customized Panel for desired Audio Objects or group of Audio Objects. Refer to Example Project: Panel Designer tab “ExampleProject” for an example of a Custom Panel.

Key Features

    • Panels View provides an ability to view, create, and import /export designed panels.
    • Ability to customize the appearance by providing background color/image, layout, font, etc.
    • Provides a tool for designing and editing the custom panel.
    • Choice of advanced controls such as panels, graphs, controls, and images to design customized panels.
    • Inbuilt user control which can be configured with specific audio object state variables and helps in tuning.

Measurement Module 

Measurement Module in Global Tuning Tool (GTT) is a powerful feature designed for performing both synchronous and asynchronous impulse response measurements and recordings. It simplifies the process of acoustic analysis and system tuning by integrating seamlessly into GTT’s signal flow.

Key Features

    • Impulse Response Measurements allow users to measure impulse responses, which are crucial for analyzing room acoustics, speaker performance, and system behavior.
    • Automatic Speaker Control – Integrated with GTT’s gain channels, the Measurement Module can automatically mute and unmute speakers during measurements, ensuring precise and interference-free acquisition.
    • Sweep Signal Generation with customizable inputs like length, stimulus placement (before/after), and other parameters. This provides flexibility in measurement setups.
    • Predefined Signal Injection -Ability to inject predefined signals such as Uncorrelated Pink Noise, Correlated Pink Noise, and Left Pink Noise These signals allow for detailed testing and analysis in asynchronous measurement scenarios.
    • Data Management – acquired measurements are stored within the project and can be exported or imported. This makes it easy to save, share, or reuse measurement data across different sessions or projects.

Central Viewer

This feature can be used for inspecting and post-processing measurements obtained using the Measurement Module. It provides advanced visualization and analysis capabilities to help users interpret the captured data effectively.

Key Features 

    • Intuitive measurement data browsing by selecting elements directly on the scene which simplifies navigation, enabling quick access to relevant measurements.
    • Support for multiple Data Visualization formats.
      •  Time Domain: Displays the raw waveform to analyze temporal characteristics.
      • Magnitude: Shows the signal’s amplitude spectrum.
      • Phase: Provides phase information for detailed signal analysis.
    • Offers flexibility in Magnitude Data Processing and displayed.
      • Raw Data: Direct representation of measured values.
      • Smoothed Data: Reduces noise for clearer trends.
      • Octave Bands: Displays frequency data in standardized bands for acoustic analysis.
    • Waterfall Graph in 3D View, Central Viewer includes a 3D visualization option for frequency analysis.
      • The Waterfall Graph is a 3D representation that maps frequency content over time.
      • It allows users to identify patterns, anomalies, and trends that are not apparent in traditional 2D plots.
      • This is especially useful for analyzing complex signals, transient behavior, and time-varying frequency content.
    • Support for mathematical operations on the measurement data, such as addition, subtraction, and averaging, enabling comparative and combinational analyses.
