捕获的Mac OS X系统的音频输出与Python [英] Capturing Mac OS X System Audio output with Python

问题描述

我一直在尝试使用劫持的Mac OS X系统的音频 PyAudio 并保存到Python中的WAV。也就是说，我不想记录从输入装置如麦克风。我想从任何或所有应用程序抢声音输出。

I've been trying to "hijack" the Mac OS X system audio using PyAudio and save to a wav in python. That is, I do not want to record from an input device such as a microphone. I want to grab the sound output from any or all applications.

我按照在PyAudio网站上的教程，但这些似乎并没有掩盖我的使用情况，当我尝试从输出流中读取我意料之中得到paCanNotReadFromAnOutputOnlyStream例外。很公平！有没有办法做我的PyAudio或其他建议源码Python库？

I have followed the tutorials on the PyAudio site but these do not appear to cover my use case and when I try to read from the output stream I unsurprisingly get the paCanNotReadFromAnOutputOnlyStream exception. Fair enough! Is there a way to do what I am proposing with the PyAudio or other FOSS Python Library?

推荐答案

我发现，称为开源项目 SoundFlower 让我迅速地，我需要的地方。

I found that an open-source project called SoundFlower got me quickly to the place I needed to be.

1. 我安装谷歌从code中的SoundFlower包。


2. 打开系统preferences - >声音


3. 之所以选择Soundflower作为输出设备


4. 之所以选择Soundflower作为我的输入设备

当时我能够录制使用PyAudio默认设​​备系统的音频。无声音从扬声器/耳机在这种情况下，虽然。我不知道是否可以使用杰克OS X路由音频输出SoundFlower到系统的音频输出。

I was then able to record system audio from the default device using PyAudio. No sound comes from the speakers/headphones in this situation though. I wonder if you could use Jack OS X to route audio out of SoundFlower to the system audio out.
