ADT NOISE SUPPRESSION C55x

DESCRIPTION

The Adaptive Digital noise suppression software reduces background noise that is present in speech signals during periods between speech periods, but not during the actual speech periods. This is a low-MIPS alternative to noise reduction, which reduces noise during speech periods also.

FUNCTION

NS_ADT_init( . . .)                  Initiates a channel of Noise Suppression

NS_ADT_reduce( . . . )           Executes Noise Suppression


APPLICATIONS

Standard noise reduction is an excellent choice for applications with high background noise environments such as mobile phones, speakerphones, hands-free phones, and defense communication systems. It is also useful when used in conjunction with voice recognition to increase accuracy.

Low Complexity noise reduction is an excellent choice for wireline telephony and conferencing.
