Question

我有一个带麦克风的Logitech摄像机。我想从python访问麦克风的麦克风

我尝试列出pyaudio中的设备，但麦克风未显示在那里。

尝试过此代码

import pyaudio
p = pyaudio.PyAudio()
info = p.get_host_api_info_by_index(0)
numdevices = info.get('deviceCount')
for i in range(0, numdevices):
        if (p.get_device_info_by_host_api_device_index(0, i).get('maxInputChannels')) > 0:
            print ("Input Device id ", i, " - ", p.get_device_info_by_host_api_device_index(0, i).get('name'))

Output1

Input Device id  0  -  HDA Intel PCH: ALC255 Analog (hw:0,0)
Input Device id  2  -  sysdefault
Input Device id  7  -  pulse
Input Device id  9  -  default

第二个代码：

import pyaudio
p = pyaudio.PyAudio()
for i in range(p.get_device_count()):
    dev = p.get_device_info_by_index(i)
    print((i,dev['name'],dev['maxInputChannels']))

Output2：

(0, 'HDA Intel PCH: ALC255 Analog (hw:0,0)', 2)
(1, 'HDA NVidia: HDMI 0 (hw:1,3)', 0)
(2, 'sysdefault', 128)
(3, 'front', 0)
(4, 'surround40', 0)
(5, 'surround51', 0)
(6, 'surround71', 0)
(7, 'pulse', 32)
(8, 'dmix', 0)
(9, 'default', 32)

未获取麦克风ID

注意-使用具有内置麦克风的Logitech摄像机

在linux（Ubuntu）上工作

使用Python访问外部麦克风
