Select for Realtek noise reduction/suppression(NR/NS) component.
Noise Suppression technology reduces stationary and transient noises in
single-channel speech signals, which increases the signal-to-noise ratio,
improves speech intelligibility and reduces listening fatigue. It estimates
ambient noise and signal levels and then passes or attenuates the signals
according to improve signal-to-noise ratios. The feature links to a
proprietary binary libSOF_RTK_MA_API.a, libSuite_rename.a, libNet.a and libPreset.a.
Please contact antz0525@realtek.com for any question about the binary.
