Variable noise masking during phases of substantial silent

机译:在基本无声的阶段进行可变噪声掩蔽

摘要

Disclosed are methods and systems for masking audio noise discloses. A device contains a silent detector, which is adapted to form a phase essential silent in an audio signal can be seen; a maskierrauschquelle, which is operatively coupled to the silent detector is coupled, wherein the maskierrauschquelle for this purpose is formed, a noise signal in response to the detection of the phase essential silent by the silent detector; and at least of a combining means, which is operatively coupled to the maskierrauschquelle coupled, wherein the at least a combining means is adapted to the combining of the audio signal and of the noise signal to contribute to. A method includes the detection of a phase essential silent in an audio signal; and combining masking noise with the audio signal during the phase essential silent.
