制作冥想音乐的程序

单独的文字音频 + 背景音乐音频合成程序：

# 加载音频文件
audio = AudioSegment.from_file(for_file)
background = AudioSegment.from_file(background_file)

# 如果背景音频短于主要音频，则重复背景音乐直到达到所需长度
while len(background) < len(audio):
    background += background

# 截取背景音频的长度与主音频相同
background = background[:len(audio)]

# 插入3秒静音，使得主音频3秒后开始合并
silence = AudioSegment.silent(duration=3000)  # 表示3000毫秒，即3秒的静音
audio = audio + silence  # 在背景音前加上静音段

# 降低背景音量，确保主音频更清晰
background_lower = background - 5  # 根据需要调整减少的 dB

# 为背景音乐的最后10秒应用淡出效果
fade_duration = 10000  # 10000毫秒 = 10秒
background_with_fade = background_lower.fade_out(fade_duration)

# 混音两个音频文件（从3秒开始）
output = background_with_fade.overlay(audio, position=3000, gain_during_overlay=0)

# 导出最终合成音频
output.export(output_file, format="mp3")
