Abstract: |
|||
| The disclosed adaptive signal amplitude control method for directional sound source comprises: normalizing the input with last frame peak as normalization standard, preprocessing for carrier modulation, hierarchical processing amplitude, and outputting the unipolar sound. This invention avoids defect in real-time led by artificial delay, and is convenient to implement in engineer as simple algorithm. | |||
