在python中通过调制解调器发送wav声音

import wave
import pyaudio

def send_wav_file(filename):
    # 打开.wav文件
    wave_file = wave.open(filename, 'rb')

    # 创建PyAudio对象
    audio = pyaudio.PyAudio()

    # 打开输出流
    stream = audio.open(format=audio.get_format_from_width(wave_file.getsampwidth()),
                        channels=wave_file.getnchannels(),
                        rate=wave_file.getframerate(),
                        output=True)

    # 读取数据并发送
    data = wave_file.readframes(1024)
    while data:
        stream.write(data)
        data = wave_file.readframes(1024)

    # 关闭流和设备
    stream.stop_stream()
    stream.close()
    audio.terminate()

    # 关闭.wav文件
    wave_file.close()

# 调用函数发送.wav文件
send_wav_file('audio.wav')
