Ansys Sound for developers

Overview

Ansys Sound is a postprocessing toolset that allows engineers to analyze and optimize their product noise using desired sound quality criteria and listening tests. Innovative time-frequency analysis and processing functions are available for isolating and modifying sound components and assessing the influence of sounds on human perception. Ansys Sound reproduces the 3D sound in simulators and vehicles, including tools to tune active sound (In Car Entertainment) or electric vehicles (EVs). For more information, see Ansys Sound.

The Ansys Sound APIs empower you to easily perform the following tasks:

  • Active Sound Design for Electric Vehicles (ASDforEV): Send the vehicle parameters to the ASDforEV application using Open Sound Control (OSC) messages over User Datagram Protocol (UDP).
  • Car Sound Simulator (CSS): Send the driving parameters to the CSS application to the application using OSC messages over UDP.
  • Virtual Reality Sound (VRS): Send source configuration and control updates to the VRS application using OSC messages over UDP.

The PyAnsys Sound library lets you use the main features of Ansys Sound to perform the postprocessing and analysis of sounds and vibrations in Python. This library is based on PyDPF-Core and the DPF Sound plugin. It is a Python wrapper that implements classes on top of DPF Sound operators.

OS and supported languages

Ansys Sound APIs for ASDforEV, CSS, and VRS rely on the OSC protocol, which is delivered over UDP. This means that these APIs are independent of the operating system and language, even if Ansys Sound is supported only on Windows.

The PyAnsys Sound library is available for Windows and Linux in Python. Note that the DPF server and DPF Sound plugin must run under Windows, and the client (the API) can be used from both Linux and Windows.
