Field Documentation

float32_t energy

saves previous frame energy.

step size that control filter coefficient updates.

uint16_t numTaps

number of coefficients in the filter.

float32_t* pCoeffs

points to the coefficient array. The array is of length numTaps.

float32_t* pState

points to the state variable array. The array is of length numTaps+blockSize-1.

saves previous input sample.
