What is an important sample we need to force in noisy cancellation?

In noise cancellation, an important sample that needs to be obtained is the reference or "noise" sample. This sample represents the background noise that is to be canceled out from the desired audio signal.The reference sample should ideally capture only the noise component without any desired audio signal. This reference sample is typically obtained by placing a microphone in close proximity to the noise source or in an environment where only the background noise is present.

It's worth noting that obtaining an accurate and representative reference sample is crucial for effective noise cancellation. If the reference sample contains any desired audio signal or if it doesn't accurately represent the background noise, the cancellation process may not be as successful in reducing unwanted noise.

WTM2101 chips have howling suppression and noisy cancellation functions, especially in noisy cancellation. The latency is less than 10ms,PESQ achieves 3.12 and STOI achieves 0.97. The noisy algorithm is significantly better than the traditional algorithm.
