我正在尝试使用诱变剂将标签写入表 .aif 文件。到目前为止没有太大的成功...

从诱变剂文档中的代码我尝试：


from mutagen.aiff import AIFF

audio = AIFF(“example.aif”)
audio["title"] = u"An example"
audio.save()

这是我想要达到的基本水平，但是我得到以下信息：


Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/ef/anaconda2/lib/python2.7/site-packages/mutagen/_file.py", line 75, in __setitem__
    self.tags[key] = value
  File "/Users/ef/anaconda2/lib/python2.7/site-packages/mutagen/id3/_tags.py", line 343, in __setitem__
    raise TypeError("%r not a Frame instance" % tag)
TypeError: u'An example' not a Frame instance

无法理解框架实例，所以我寻找其他方法来做到这一点，例如如下 ID3 类：



from mutagen.id3 import ID3

    tags = ID3()

tags.save("song.mp3")

不返回错误，但是 .aif 文件返回损坏。

所以我接着看直接从.aif 加载 ID3 文件——这失败了，因为不存在 ID3 标签……</p> 



from mutagen.id3 import ID3, TIT2

    audio = ID3("example.aif”)

    audio.add(TIT2(encoding=3, text=u"An example"))

    audio.save()

audio = ID3("example.aif") 给出：

当你这样做时：

audio["title"] = u"An example"

您正在为标签分配一个字符串。但是 Mutagen 需要一个文本框架（如错误消息所示），其定义如下：

mutagen.id3.TextFrame(encoding=<Encoding.UTF16: 1>, text=[])

所以，做

audio["title"] = mutagen.id3.TextFrame(encoding=3, text=[u"An example"])
