列出与Python的pyaudio所有的音频设备（portaudio绑定） [英] List all audio devices with Python's pyaudio (portaudio binding)

问题描述

我试过

import pyaudio
p = pyaudio.PyAudio()
for i in range(p.get_device_count()):
    print p.get_device_info_by_index(i)

但我没有得到所有设备的完整列表：比如我并不在此列表中获得ASIO设备。这就奇怪了，因为 portaudio 应该给ASIO设备，以及，对吧？

but I don't get the full list of all devices : for example I don't get ASIO devices in this list. This is strange, because portaudio should give ASIO devices as well, right ?

如何列出所有的音频设备 pyaudio ？

How can I list all audio devices with pyaudio ?

推荐答案

我觉得你的期望是合理的。等效C code到枚举PortAudio设备会给你所有可用设备。有一对夫妇的事情是错的：

I think your expectations are reasonable. The equivalent C code to enumerate PortAudio devices would give you all available devices. There are a couple of things that could be wrong:

• 您PyAudio的构建尚未编译ASIO支持。 PortAudio只列举设备编译时编译已配置本地主机的API /。

• Your build of PyAudio has not been compiled with ASIO support. PortAudio will only enumerate devices for the native host APIs that have been configured/compiled in at compile time.

您的Python / PyAudio和你ASIO的64位版本的设备驱动程序是32位或VIS-反之亦然（64位ASIO驱动程序和32位的Python）。

You have a 64-bit build of Python/PyAudio and your ASIO device drivers are 32-bit, or vis-versa (64-bit ASIO drivers and 32-bit Python).

多媒体麦克建议，可以从公式由PortAudio分布从C枚举PA设备的pa_devs.c程序消除PyAudio做到这一点。

As Multimedia Mike suggests, you can eliminate PyAudio from the equation by enumerating PA devices from C. The pa_devs.c program in the PortAudio distribution does this.
