问题描述
我一直在使用进口在过去的声音文件，和它的工作相当不错。但是：
I've been using Audiolab to import sound files in the past, and it worked quite well. However:
- 它不支持某些格式，如MP3，因为基础libsndfile 之下，作者是绕不解决它
- It doesn't support some formats, like mp3, because the underlying libsndfile refuses to support them
- It doesn't work in Python 2.6 under Windows, and the author is not around to fix it
-
In [2]: from scikits import audiolab
--------------------------------------------------------------------
ImportError Traceback (most recent call last)
C:\Python26\Scripts\<ipython console> in <module>()
C:\Python26\lib\site-packages\scikits\audiolab\__init__.py in <module>()
23 __version__ = _version

---> 25 from pysndfile import formatinfo, sndfile
26 from pysndfile import supported_format, supported_endianness, \
27 supported_encoding, PyaudioException, \
C:\Python26\lib\site-packages\scikits\audiolab\pysndfile\__init__.py in <module>()
----> 1 from _sndfile import Sndfile, Format, available_file_formats, available_encodings
2 from compat import formatinfo, sndfile, PyaudioException, PyaudioIOError
3 from compat import supported_format, supported_endianness, supported_encoding
ImportError: DLL load failed: The specified module could not be found.``
所以我想要么：
- 弄明白为何它不是在2.6的工作（有毛病_sndfile.pyd？），也许找到一个方法来扩展它不支持的格式工作
- 找到了AUDIOLAB的完整的替代
推荐答案
AUDIOLAB的为我工作在Ubuntu 9.04与Python 2.6.2，所以它可能是一个Windows的问题。在你的链接到论坛上，笔者还认为，这是一个Windows错误。
Audiolab is working for me on Ubuntu 9.04 with Python 2.6.2, so it might be a Windows problem. In your link to the forum, the author also suggests that it is a Windows error.
在过去，这个选项很适合我，太：
In the past, this option has worked for me, too:
from scipy.io import wavfile
fs, data = wavfile.read(filename)
只是要注意，数据可能已 INT 数据类型，所以它不是在[1,1缩放）。例如，如果数据是 INT16 ，你必须把数据按 2 ** 15 来内部扩展[-1,1）。
Just beware that data may have int data type, so it is not scaled within [-1,1). For example, if data is int16, you must divide data by 2**15 to scale within [-1,1).
这篇关于导入声音文件到Python作为numpy的阵列（替代AUDIOLAB）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
