ACTIVE NOISE EQUALIZATION |
| 摘要 |
An active noise equalization (ANE) system may be run on the existing audio/infotainment system as a software library. The ANE system may share components (e.g., microphones and sensors) with other audio applications. Some ANEs include a complex-domain formulation of a multiple-frequency multiple-channel ANE that requires less memory and processing requirements. The complex-domain system replaces the multiplication of multiple real gains with multiple real signals with a single complex multiplication operation. |

1. A method for active noise equalization comprising:
obtaining a sync signal associated with a noise source reproduced into an acoustic space; generating a noise model, representing one or more complex tones, responsive to the sync signal; receiving an audio signal representing a sound field in the acoustic space; and applying a transformation function to the noise model where the transform function is responsive to reducing the sum of the output of the transformation function and the received audio signal. |
