So I found that the <strong>sounddevice<\/strong> <strong>module<\/strong> was the best for my purpose and that&#8217;s how easy is to get it and use it in a program that needs it. You can check the <strong>specs<\/strong> too of the devices.<\/p>\n<p>So, if you need to know the name that windows uses for its devices, like a microphone for example, in your programs you can do this:<\/p>\n<pre class=\"lang:default decode:true\">import sounddevice as sd\r\n\r\ndef get_mic_name():\r\n    \"Uses sounddevice to get the name of the mic in case it changed\"\r\n    s = sd.query_devices()\r\n    audio = f\"\"\"{s[1][\"name\"]})\"\"\"\r\n    return audio\r\n\r\nname = get_mic_name()<\/pre>\n<p>So, here I am getting the name of the mic, that (in my case) is the &#8220;name&#8221; key of the second dictionary in the list of dictionaries that are made by the query_devices function class of sounddevice.<\/p>\n<p>Watch the video to get an example of use of it.<\/p>\n<p><iframe loading=\"lazy\" title=\"Get the windows device name with Python and sounddevice\" width=\"747\" height=\"560\" src=\"https:\/\/www.youtube.com\/embed\/_hZxauH1RQI?feature=oembed&amp;enablejsapi=1\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h2>The program I use to record the screen<\/h2>\n<p>This needs to be adapted to your needs, but I post it here in case you could take some tips out of it for your needs.<\/p>\n<pre class=\"lang:default decode:true \">import os\r\nimport glob\r\nimport sounddevice as sd\r\n\r\n\r\nx = 0\r\n\r\ndef ask():\r\n    root = \"G:\\\\video\\\\\"\r\n    filename = input(\"Nome del file: \")\r\n    filepath = root + filename + \".mp4\"\r\n    return filepath, root\r\n\r\ndef automatic_name():\r\n    \"Crea il nome da solo \/ ora chiedo il nome del file prima\"\r\n    global x\r\n\r\n    fld = \"G:\\\\video\"\r\n    if not fld + str(x) + \".mp4\" in glob.glob(fld + \"*.mp4\"):\r\n        filename = fld + str(x) + \".mp4\"\r\n    else:\r\n        x += 1\r\n        record()\r\n    filename = fld + filename + \".mp4\"\r\n    return filename\r\n\r\n\r\ndef get_mic_name():\r\n    \"Uses sounddevice to get the name of the mic in case it changed\"\r\n    s = sd.query_devices()\r\n    audio = f\"\"\"{s[1][\"name\"]})\"\"\"\r\n    return audio\r\n\r\n\r\ndef record(filename):\r\n    #
