Abstract
The disclosure relates to a method and system for adjusting audio signals by a digital signal processor (DSP). The method comprises receiving an audio signal, adjusting the audio signal and transferring the adjusted audio signal to be output by one or more speakers. The method further comprises receiving sensor data indicative of an air environment around the one or more speakers and adjusting the audio signal based on the sensor data. The method and system may be employed in a vehicle.
Claims18
A method for adjusting audio signals by a digital signal processor (DSP), the method comprising:
- receiving an audio signal;
- adjusting the audio signal;
- and
- transferring the adjusted audio signal to be output by one or more speakers;
- receiving sensor data indicative of an air environment around the one or more speakers;
- generating an optimized dynamic compensation transfer function by training a neural network using a pre-determined set of sensor data including pre-determined temperature data, altitude data, and humidity data;
- and
- adjusting the audio signal based on the sensor data and the dynamic compensation transfer function.
A system for adjusting audio signals, the system comprising:
- one or more sensors;
- one or more speakers;
- an amplifier comprising a digital signal processor (DSP) and being configured to:
- receive an audio signal;
- adjust the audio signal;
- transfer the adjusted audio signal to be output by the one or more speakers;
- receive sensor data indicative of an air environment around the one or more speakers;
- generate an optimized dynamic compensation transfer function by training a neural network using a pre-determined set of sensor data including pre-determined temperature data, altitude data, and humidity data;
- and
- adjust the audio signal based on the sensor data and the dynamic compensation transfer function.
