Audio Weaver The Unified Audio Development Platform

Design

Audio Weaver is the only tool you need to quickly develop and prototype system level concepts, new user modes and custom IP. With over 500 audio processing modules, DSP Concepts audio IP and a broad selection of automotive audio 3rd party IP, you can create complex audio signal flows with an easy drag and drop visual environment. You and your team can explore your options in a low-code environment that accelerates innovative designs without waiting for the software team to translate your ideas.

Develop

Audio Weaver partners with the leading ICs, empowering you to put your design on any target hardware you choose painlessly. Suddenly your creation is live on the intended target —to test audio performance, visualize critical signals and parameters and validate system hardware and interfaces — without leaving Audio Weaver. This unprecedented workflow simplifies and accelerates system level debugging. Audio Weaver can also be used to create specific validation features and even end-of-line test features to speed vehicles off the line with known quality.

Deploy

Real-time audio is difficult, especially on a multi-threaded, multi-core system. Audio Weaver makes performance easy, ensuring that your designs run in real time on any target environment without any hiccups. Audio Weaver provides top level profiling data as well as function by function and module by module details, in real time, to assist designers. With Audio Weaver, you can make critical tradeoffs to match real time budgets for any use case. If needed, you can modify algorithmic approaches while viewing CPU performance on the target device in a user friendly graphical design environment. Audio Weaver ensures the best audio functionality and performance achievable on any processor.

And since Audio Weaver is hardware agnostic, never start from scratch again on every new vehicle development, just because a new SOC or DSP is used in the design. Use Audio Weaver across vehicle lines and product segments to deploy proven designs with consistent behavior, audio performance and user experience. Regardless of hardware changes, you maintain control of the audio features, concepts and IP.

  • Acoustic Echo cancellation technology supporting multiple playback channels

Provide seamless integration for embedded and cloud based speech recognition engines — so they work better in noisy, multi-passenger environments.

Sound Generation

Many automotive applications require unique sounds, including external engine sounds, internal engine sounds, AVAS sounds for warning nearby pedestrians or other signature sounds. By providing an Audio Weaver layout with all the essential elements, you can scale a synthesizer to your specific needs and CPU capabilities. Audio Weaver provides:

  • Vehicle data interpreters, multiple controllable WAV file generators and standard signal generators.
  • Sound generation can be designed, developed and deployed along with entertainment audio system designs -- no need for additional tools.

Have complete control over any sounds using a configurable system, for added flexibility and accelerated creation.

Tuning Tool

Finally, when the new audio system is presented to the acoustics team for system tuning, DSP Concepts offers a full suite of vehicle acoustic tuning tools, separate from Audio Weaver, that transforms real-time audio tuning.

  • Our tools and approach are systematic, analytical, highly automated and create repeatable successful results.
  • Tuning sessions that typically require a week or more in a scarce prototype vehicle are reduced to hours, freeing up the vehicle for use by other engineering groups.

Create an acoustic fingerprint, tune against the fingerprint instead of the car, speed this crucial final step in the sound system development process.

Automotive Measuring System - AMS

Conventional tuning requires far too much time in the prototype. The Automotive Measuring Suite measures the acoustical fingerprint of the vehicle, creates a model, and lets audio engineers tune vehicle acoustics without access to the vehicle.

  • Hundreds of speaker to listener transfer functions are captured, measure up to 32 speaker channels and use up to 8 microphones in parallel.
  • Take thousands of measurements in less than 2 hours, browse, compare, and export measurements.

Send a technician to collect all the measurements you need and create a model for offline tuning. No expert needed for measurements.

Automotive Tuning System - ATS

ATS is an offline tuning system that supports analysis of the vehicle measurements and creating automated filters and time alignment parameters. With it, acoustic engineers can explore measurements, optimize EQ, and modify designs by hand.

  • Import data from AMS or previous tuning sessions
  • Display time and spectral responses for all seat positions
  • Create filter parameters and an automated tuning report for documentation
  • Tune for different multiple seat locations at the same time

Tune without the vehicle, even offsite. Add flexibility, improve collaboration, free the vehicle for other uses, tune the vehicle when you’re ready.

Automotive Prototyping System - APS

Often the most challenging stage of deployment is the final tuning stage. Automotive Prototyping Suite, or APS, runs in the target environment on Audio Weaver, and supports live final tuning in the vehicle.

  • Import parameters from the ATS system into the target hardware
  • Listen to the results in the vehicle with sample content
  • Create candidate tunings and switch seamlessly among three options (A/B/C switch)
  • Includes typical audio functionality - bass, treble, balance, fade to assist evaluation. Includes all the use modes the system supports.
  • If target hardware is not available, APS can be used on the ASIO sound card tuning kit.

With APS, making minor changes to the vehicle acoustic response becomes easy, fast, and repeatable.
