This is a sound effect that you can use free for your homework's , it was recorded in home studio, it mas recorded on macbook loptop keyboard and pressing some letters.
A short recording of me typing on my phone. A couple of breath sounds interrupt so apologies for that but hopefully a helpful little recording!. Recorded over laptop mic. Sound of a samsung s8 keyboard.
It is a sound that presents several alterations because sometimes it is perceived strong but there are moments in which it becomes weak and the sound is lost. It was triggered by a person pressing the keyboard keys to type.
A setting on my toy keyboard called "pearl drop" shifted two octaves down (shifting this far down made the sound just start to break up in a glitchy sounding way).
