如何使用Ruby或Python创建一系列高音和低音哔声？

import numpy as np
import simpleaudio as sa

def generate_sound(freq, duration, volume=0.1):
    sample_rate = 44100
    t = np.linspace(0, duration, duration * sample_rate, False)
    sound_wave = np.sin(freq * t * 2 * np.pi)
    audio_wave = (volume * sound_wave * 32767).astype(np.int16)
    return audio_wave

def play_sound(audio_wave, sample_rate=44100):
    play_obj = sa.play_buffer(audio_wave, 1, 2, sample_rate)
    play_obj.wait_done()

high_freq = 440  # 高音
low_freq = 880  # 低音
duration = 1  # 持续时间（秒）

high_sound = generate_sound(high_freq, duration)
low_sound = generate_sound(low_freq, duration)

play_sound(high_sound)
play_sound(low_sound)
