The farther you are away from the microphone, the softer your voice will be recorded. That’s pretty obvious, but your voice will also begin to become less distinct from other noises in the environment (more on this in the next section).
If you are able to get an external microphone, this can greatly assist your ability to be close to the mic. If you have to use the built-in mic, try to be as close as you can to your laptop or phone while still maintaining the proper video composition guidelines that we covered above.
