OBS Studio (FREE) - Record Background Window with Audio on Windows – Can Hear While Recording

You can do something else while the app is recording a screen but the result contains black part when window is resized or the target area won’t fit the frame.




The test steps – OBS Studio 32.0.1

On: Windows 11 Home

Download from https://obsproject.com/download


1. Go to the link above to download a file.



Open the downloaded file.



The dialog ‘User Account Control’ shows, click ‘Yes’



Follow the on-screen window to install the app.



When it’s done, click ‘Finish’.



2. OBS Studio opens.



I chose ‘Optimize just for recording….’ by clicking in front of the line, the blue circle will be placed.



The next window shows.



You can see the options I chose in the picture above.



The final result shows, click ‘Apply Settings’.



The picture above is the target window. Video and audio playing with the app called ‘VLC’.


3. The main window shows.



At section ‘Source’, click +.



Select ‘Window Capture’.



The new window shows, click ‘OK’.



The next window shows, I selected ‘VLC…’ in the list of windows. And I checked ‘Capture Audio (BETA) then click 'OK'.



In the picture above, you can see the frame and the target window. You can resize or move the target window.



At ‘Control’ section, I clicked ‘Start Recording’.



The button will be changed to ‘Stop Recording’.



The result is, this app can not recording video playing in ‘VLC’ player.



But it can record audio coming from ‘VLC’ player.



In the picture above is properties of the output video, you can see the audio and video info.


When I resized the target window while recording, there is no issue.


I moved the target window while recording but the video in the output file was not moved.


I made the target window a background window while recording but the video in the output file, the target window did not stay in the background.


4. I changed target window to Firefox browser. There was no issue, it could record audio and video playing in the browser.


When I resized the target window while recording, the background window did not show in the video in the output file.


I don’t like the black part in the output file, I remember version of this app on macOS, there is no black part if I don’t resize the target window.

AutoHotkey (FREE) – Hold Down a Mouse Button with a Keyboard Shortcut on Windows 11

I don’t know the reason why people want to do this thing, it might be because of the computer screen is too big to drag something for too long. The script helps, just move the mouse, not holding anything.


I found the script here https://stackoverflow.com/questions/1993003/holding-down-the-left-mouse-button-in-autohotkey


The code is below.


F2::

alt := not alt

if (alt)

{

Click down

}

else

{

Click up

}

Return



Code explanation:

Pressing F2 (FN+F2) will hold down a left mouse button.


Usage: run the code (read how-to below), locate a mouse pointer where you want to drag it or do something else, press F2 then start dragging something. To cancel holding down, click a left click.


How to run the code.

1. Download AutoHotkey from https://www.autohotkey.com/



Click a button ‘Download’.



You will see there are 2 versions, I download both of them because some code can not be run with the old/new version.


Open the downloaded files and follow steps to install apps.


From my memories, you don’t have to open the apps because after installation is done, the apps will run in the background.


2. Copy the code above, open new document of Notepad, paste the code. You can change the first line to F2, F3…


Save it then add the extension .ahk.



To run the code, right click at .ahk file, then click the menu ‘Open’ near the icon ‘AutoHotkey’. (see the picture below)



You can see the script by clicking an arrow at the taskbar.



The code below is for holding down a right click button.


F3::Click % "right " (GetKeyState("RButton") ? "Up" : "Down")


Code explanation:

Pressing F3 (FN+F3) will hold down a right mouse button.


Usage: run the code (read how-to above), locate a mouse pointer where you want to drag it or do something else, press F3 then start dragging or something else. To cancel holding down, press F3 again.


You can change F3 to something else, such as F2,F4…


Important note: for 1st code, to cancel holding, just click a left click button.

For 2nd code, to cancel holding, press F3 again.


I tested 2nd code with Gesturefy (Firefox add-on) by setting a right click button as a target button to be held for performing gestures. It works fine.

Net Speed Meter – Monitor Uploading and Downloading Speed FREE on Windows 11

I uploaded a very big size of file and switched to other windows but wanted to know the process of uploading. I had to switch to uploading window to check it. So I wanted a better way, what I’ve found is network monitoring app.



It doesn’t tell my uploading is done or not but I can check the speed. If the speed is in KB, I’m pretty sure that my uploading is done.

Download from Microsoft Store


1. Open the app ‘Microsoft Store’ ( you don’t have to install, it comes from Windows 11). Then search the name of the app and install it.



I went to netspeedm.com. It says ‘Free and easy to use’. I went to ‘our product’ section, then click ‘Net Speed Meter’. It took me to Microsoft store, I downloaded the app.



I opened the downloaded file.



A new window showed and installation started.




2. After installation is done, a small floating window shows at the right corner of the screen.



You can move that window to where you want by dragging.




I tested downloading something.



1st value is downloading speed.

2nd value is uploading speed.


I tested uploading something.



You can quit the app by right clicking at the window, then select Exit.

the default setting is enough for me.
