Python加载声音

对于音频的操作可以使用pygame包中的sound 和 music对象进行音乐播放。

Sound对象适合处理较短的音乐，如OGG和WAV格式的音频文件。

Music对象出来可以播放OGG、WAV音频外，还可以播放mp3格式。

from pygame import mixer #mixer对象可以播放音乐

一、Sound 对象

mixer.init() 先初始化

创建Sound对象

sound = mixer.Sound(音频文件名)

sound.play(loops = 0) 播放音乐，loops代表播放次数，默认为0，表示播放一次；loops=5可播放6次；loops=-1 可重复播放

sound.stop() 结束播放

sound.set_volume(value) 设置音量，音量有最低到高0.0--1.0

sound.get_volume() 获取当前的音量

二、music对象

mixer.init() 先初始化

mixer.music.load(filename) 停止正在播放的音乐，filename为歌曲的文件名

mixer.music.play(loops=0,start=0.0) 播放歌曲，loops表示播放次数，默认为0，播放1次；loops=5可以播放6次；loop=-1可以重复播放

mixer.music.stop() 停止播放

mixer.music.pause() 暂停播放

mixer.music.unpause() 用pause()暂停后，必须使用这个函数来继续播放

mixer.music.set_volume(value) 设置音量，最大1.0，最小0.0

mixer.music.get_volume() 获取当前音量

mixer.music.get_busy() 检查歌曲播放状态，True为正在播，False为不在播
