Automotive Audio Processing Functions
Speaker and subwoofer tuning
Audio Weaver’s automotive audio processing interface provides all the filters, limiters and other processing needed to get optimum sound in any car. Every module is easily adjustable using familiar onscreen controls.
Extensive, fully variable and adjustable filters allow engineers to get the best possible performance from any driver configuration and any driver positions.
Microphone processing and tuning
Our automotive audio processing algorithms can tune and optimize signals for microphones used for voice communications (i.e., hands-free phone calls) to make voices clearer and easier for the person on the other end of the connection to understand.
Microphone noise and echo cancellation
Noises that interfere with microphone operation, such as road and engine noise and the sounds coming from an entertainment system, can be effectively cancelled with Audio Weaver®, allowing clearer voice communications and more reliable voice command functions.
Microphone array beamforming
Our algorithms can process signals from two or more microphones to produce “beaming” pickup patterns to better isolate and clarify the sound of the person speaking. It can automatically focus on the voice of any occupant in a car.
Wake word detection for voice command systems
Our wake word detection algorithm allows any pre-programmed trigger/wake word to activate a car’s voice command functions.
Any desired alert tones can be provided through Audio Weaver®, whether synthesized (beep/buzzer tones) or sampled (voice feedback).
Engine/operating sound synthesis
The driver/passenger experience can be enhanced through synthesis of engine and operating sounds (such as doors closing), played back through the car’s speakers.
Many countries require quiet electric vehicles to produce warning sounds so pedestrians and cyclists can hear them. Audio Weaver® modules allow synthesis of these sounds and also allow beamforming to direct the sounds forward.
