PyAudio如何将频率范围组合在一起

import pyaudio
import numpy as np

# 设置音频参数
sample_rate = 44100  # 采样率
duration = 5  # 持续时间（秒）
frequency = 440  # 频率（Hz）

# 生成时间序列
t = np.linspace(0, duration, int(sample_rate * duration), endpoint=False)

# 生成正弦波信号
signal = np.sin(2 * np.pi * frequency * t)

# 将信号转换为16位整数
signal = (signal * 32767).astype(np.int16)

# 初始化PyAudio
p = pyaudio.PyAudio()

# 打开音频流
stream = p.open(format=pyaudio.paInt16,
                channels=1,
                rate=sample_rate,
                output=True)

# 播放音频信号
stream.write(signal.tobytes())

# 停止音频流
stream.stop_stream()
stream.close()

# 终止PyAudio
p.terminate()
