3 Basic Concepts

4 Top 8 Tips for Better Audio Recording: Use a quality microphone Monitor the sound Limit background noises Maintain a consistent environment Turn off the music Record background sound Watch out for wind Add it later

5 Top Tip #1 Use a Quality Microphone: Microphones that are built into camcorders are generally low quality no matter how expensive the camcorder Whenever possible, use external microphones away from the camera in order to optimize sound and record less noise coming from the camera

6 Top Tip #2 Monitor the Sound: Look on your camera and check for an audio jack If there is an audio jack, plug in a pair of headphones and use them while you are recording If you do this, you will hear the sound that the camera records exactly how it records so that you know whether or not you need to find a way to improve the technology that you are using to record your audio

7 Top Tip #3 Limit Background Noises: You want to limit the amount of background noises that you pick up on the recorder for two reasons it can make for difficult editing later and it can be too much of a distraction during the recording Turn off fans, loud technology, radios, televisions, close windows, and go to a place that is not crowded with other people to get good quality recordings

8 Top Tip #4 Maintain a Consistent Environment: The more you control the recording environment, the better quality audio you can record When you maintain a consistent environment and procedures, you re better able to match the audio quality in all of your recordings Consistency is quality

9 Top Tip #5 Turn Off the Music: If there is music playing in the background, turn it off in order to avoid background noises so your audio will have better quality Leaving it on will make it difficult to edit later and will make it difficult to hear what you are actually recording If you want music in with your audio, you can always add the music in later after you record your intended audio

10 Top Tip #6 Record Background Sound: Think about the environment that you are recording your audio If you are intending to record your audio, for example, in a city setting, record the audio separate from the background city noise so you can control how loud the city noises are in the background of your audio Just make sure that the background noise matches the other audio in your recording

11 Top Tip #7 Watch Out for Wind: Recording in an outdoor setting creates all sorts of different challenges, one of them being the natural noises of the outdoors Wind can be a large noise disturbance while you are recording. It will completely muffle out all audio because it will go right into the microphone You can buy a wind protector or just a sock!

12 Top Tip #8 Add it Later: Remember: you can always add sound later to your initial recording, whether that be environmental noises, sound effects, or music If you choose to record narration, wait until you are in a much quieter space
