Systems and methods for detecting silences in audio signals |
摘要 |
Silences are detected when a local signal power is below a given fixed or relative threshold value, the duration of the local signal power being below the given fixed or relative threshold value is within a first range and at least one of the parameters signal power fall/rise rate and local power deviation falls within a respective further range. The invention further relates to the use of such a silence detection in a receiver (1).
