If you need to reduce the 8K, 16K, 32K, 48K sample rate of audio data to 4K audio data, the simplest way to pick points based on the frequency reduction, but the linearity is not good. Another way to better linearity is to take the appropriate number of points, multiply the points by the coefficients of the respective points, and then add the average. The relationship between the frequency reduction multiplier and the coefficient is as follows: Twice times: {0.3, 0.4, 0.3} 4 times times: {0.15,
