Changing microphone volume using Python, Windows 10
To change the microphone volume using Python on Windows 10, you can utilize the pycaw
library, which provides an interface to control audio devices on Windows. Here's an example of how you can adjust the microphone volume using pycaw
:
Install the required library: Open a command prompt and run the following command to install
pycaw
:pip install pycaw
Write the Python code: Create a Python script and add the following code:
pythonfrom ctypes import cast, POINTER
from comtypes import CLSCTX_ALL
from pycaw.pycaw import AudioUtilities, IAudioEndpointVolume
def change_microphone_volume(volume):
devices = AudioUtilities.GetSpeakers()
interface = devices.Activate(IAudioEndpointVolume._iid_, CLSCTX_ALL, None)
volume_object = cast(interface, POINTER(IAudioEndpointVolume))
volume_object.SetMasterVolumeLevelScalar(volume, None)
# Example usage: Set the microphone volume to 50% (0.5)
change_microphone_volume(0.5)
In the
change_microphone_volume
function, you can specify the desired volume level as a scalar value between 0.0 (mute) and 1.0 (maximum volume). Adjust the volume value as per your requirements.Run the Python script: Execute the Python script, and it will change the microphone volume to the specified level.
Make sure your microphone is set as the default recording device on your system. Also, note that pycaw
is a Windows-only library and may not work on other operating systems.
Remember to run the script with appropriate permissions, especially if you're modifying the microphone volume for system-wide audio settings.
Additionally, it's worth noting that the pycaw
library provides more advanced functionality for audio control on Windows, such as managing playback devices and handling mute status. You can refer to the pycaw
documentation for more details on these features.
