NoiseControlSound (NCS)
NCS is based on an innovative patented technology that delivers a high performance single-mic noise suppression not only for relatively simple stationary noises, but also for more challenging non-stationary or time varying noises that typically would be found in daily life conditions. 

NCS passes 3GPP and China Mobile noise suppression quality requirements for dual-mic based phones, allowing therefore mobile phone OEMs to reduce cost by using only one microphone for low cost markets without compromising user experience. 

It is commercially deployed at large scales for both normal phone calls (2G/3G circuit-switched) or PS (packet-switched) field applications such as noise suppression for WeChat. 

It is suitable or even essential for the following applications:

* Wearables are size, cost and power constrained, it is a natural choice to use a single mic for audio input, requiring therefore a single mic NS
* Low-end phones with single mic are still shipping in 100s of Millions, e.g., feature phones or even simplified phones (some phones are barely bigger than a match box). NCS is ideal to realize savings on BOM by eliminating expensive extra microphones while still maintain high quality user experience
* High-end dual-/multi-mic enabled phones also need single-mic NS: when in Earphone, Bluetooth or Hands-free modes only one mic, or one channel of voice input is available, single mic NS is a must
* Short voice message services like WeChat or WhatsApp can benefit from NCS during recording, or during playback
* High quality noise suppressor for audio/video recording on mobile phone or camcorder
* High quality noise suppressor during playback for user provided media entertainment like YouTube or Youku
