What Is Comfortable Noise Generation?

- Jul 03, 2018-

The basic principle of comfort noise generation: artificially constructing noise based on the power spectral density of the noise. It is widely used in audio codecs. The white noise power spectral density at the time of muting is calculated at the encoding end, and the silent period and power spectral density information are encoded. At the decoding end, random white noise is reconstructed based on time information and power spectral density information.

Its application scenario: When it is completely muted, in order to create a comfortable call experience, random white noise is added during the audio post-processing stage.
