如何将缓冲区数组转换为音频文件

import wave

def convert_buffer_to_audio(buffer, output_file):
    # 确定音频文件的参数
    channels = 1  # 单声道
    sample_width = 2  # 16位采样
    sample_rate = 44100  # 44.1kHz采样率

    # 创建音频文件对象
    audio_file = wave.open(output_file, 'wb')

    # 设置音频文件的参数
    audio_file.setnchannels(channels)
    audio_file.setsampwidth(sample_width)
    audio_file.setframerate(sample_rate)

    # 将缓冲区数组写入音频文件对象
    audio_file.writeframes(buffer)

    # 保存音频文件
    audio_file.close()

# 示例用法
buffer = b'\x00\x00\x80\x7f\x00\x00\x80\x7f'  # 示例缓冲区数组
output_file = 'output.wav'  # 输出文件路径
