| 发明名称 | System and method for dynamic residual noise shaping | ||
| 摘要 | A system and method for dynamic residual noise shaping configured to reduce hiss noise in an audio signal. The system and method may detect an amount and type of hiss noise. The system and method may limit calculated noise suppression gains responsive to the detected amount and type of hiss noise. The limited noise suppression gains may be applied to the audio signal and may reduce the hiss noise. | ||

| 主权项 | 1. A dynamic residual noise shaping method, comprising: detecting an amount of high frequency hiss noise in an audio signal by a computer processor; calculating noise suppression gains by the computer processor by applying a noise reduction filter to the audio signal; modifying the calculated noise suppression gains by the computer processor responsive to the detected amount of high frequency hiss noise; and applying the modified noise suppression gains by the computer processor to the audio signal. | ||
