如何将16位PCM音频字节数组转换为double或float数组？

#include <iostream>
#include <cstdint>
#include <cmath>

int main() {
    uint8_t pcm[] = {0, 1, 2, 3, 4, 5, 6, 7, 8}; // 16位PCM音频字节数组
    uint32_t pcm_32bit[16];

    for (int i = 0; i < 16; i++) {
        pcm_32bit[i] = (uint32_t)pcm[i] << 16;
    }

    double double_array[16];
    float float_array[16];

    for (int i = 0; i < 16; i++) {
        double_array[i] = static_cast<double>(pcm_32bit[i]) / 32768.0;
        float_array[i] = (float)double_array[i];
    }

    // 输出double数组
    for (int i = 0; i < 16; i++) {
        std::cout << double_array[i] << " ";
    }
    std::cout << std::endl;

    // 输出float数组
    for (int i = 0; i < 16; i++) {
        std::cout << float_array[i] << " ";
    }
    std::cout << std::endl;

    return 0;
}
