使用pyaudio生成振幅递增的音调

import pyaudio
import numpy as np

sample_rate = 44100  # 采样率
duration = 5  # 持续时间（秒）
frequency = 440  # 初始频率（Hz）
amplitude = 0.3  # 初始振幅

p = pyaudio.PyAudio()
stream = p.open(format=pyaudio.paFloat32,
                channels=1,
                rate=sample_rate,
                output=True)

frames = []
num_samples = int(sample_rate * duration)
for i in range(num_samples):
    t = float(i) / sample_rate
    value = amplitude * np.sin(2 * np.pi * frequency * t)
    frames.append(value)
    amplitude += 0.001  # 振幅递增步长

audio_data = np.array(frames, dtype=np.float32)

stream.write(audio_data.tobytes())
