捕捉音频输出的Python [英] Capture audio out Python

问题描述

我想从音频输出，使用Python捕获原始数据。在Python文档似乎使用ossaudiodev适用于这一目的。不过，我使用Ubuntu 11.10，它没有为/ dev / DSP：

I would like to capture raw data from the audio out, using Python. In the Python docs it seems that using ossaudiodev works for this purpose. However, I am using Ubuntu 11.10, which has no /dev/dsp:

>>> import ossaudiodev
>>> ossaudiodev.open('r');
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IOError: [Errno 2] No such file or directory: '/dev/dsp'

有没有人得到一个线索如何捕捉声音使用Python我的声卡输出？

Has anybody got a clue how to capture the sound my sound card outputs using Python?

推荐答案

OSS是pcated音频系统用于Linux的老年人和德$ P $。本标准为使用ALSA，并与任意一个插孔或ALSA的PulseAudio的顶层。 Ubuntu使用了PulseAudio。

OSS is an older and deprecated audio system for Linux. The current standard is to use ALSA, and to layer on top of ALSA with either JACK or PulseAudio. Ubuntu uses PulseAudio.

你能做的最好的事情是要找到好的Python绑定连接的PulseAudio。我只是做了快速谷歌搜索和你没有发现任何东西，我没有时间跟进更多的现在。

The best thing you could do is to find good Python bindings for connecting to PulseAudio. I just did a quick Google search and didn't find anything for you, and I don't have time to follow up more right now.

编辑：我只记得那ALSA确实有一个OSS兼容模式。您可能能够安装OSS兼容的东西，那么就使用Python code你已经离开。

I just remembered that ALSA does have an OSS compatibility mode. You might be able to install the OSS compatibility stuff, then just use the Python code you already have.
