如何将头信息添加到wav文件中以获得与ffmpeg相同的结果？

import wave

def add_header_to_wav(source_file, destination_file, sample_rate, bit_depth, channels):
    # 打开源文件
    with wave.open(source_file, 'rb') as source:
        # 读取源文件的参数
        params = source.getparams()

        # 设置新的头信息参数
        new_params = wave.Wave_write.getparams(
            nchannels=channels,
            sampwidth=bit_depth // 8,
            framerate=sample_rate,
            nframes=params.nframes,
            comptype=params.comptype,
            compname=params.compname
        )

        # 打开目标文件
        with wave.open(destination_file, 'wb') as destination:
            # 设置目标文件的参数
            destination.setparams(new_params)

            # 读取源文件的音频数据并写入目标文件
            audio_data = source.readframes(params.nframes)
            destination.writeframes(audio_data)

# 示例用法
add_header_to_wav('input.wav', 'output.wav', 44100, 16, 2)
