### **1\. Silence everything you don’t want your microphone to record**
When you’re recording audio, you have to be more aware of the subtle sounds that drone on in your background. These sounds may include humming from machines with fans, buzzing from lights, and jingling from your pet’s collar. Observe your recording space and find ways to silence everything that you don’t want in your audio recording.
2. Put your mobile phone in airplane mode Although it may be quite obvious to turn your phone’s ring tone off when you’re recording, it may not be as obvious to put your phone in airplane mode. When phones receive calls or perform searches as part of their background processes, they emit signals that can get picked up by your recording system. Avoid ruining good takes with unwanted sounds of phone signals by putting your phones in airplane mode.
3. Minimize echo If you are recording yourself talk or sing, make sure to set up your recording space in a way where the sound projected from your voice bounces minimally off the walls and back to your microphone. Bare walls and hardwood floors will cause a lot of bouncing. Make use of materials that will absorb your sound rather than bounce it, like a thick rug or a comforter. If you want your voice to echo, that’s something you should do in post-production.
4. Block wind from reaching your microphone Although it might not sound so loud and distracting to the naked ear, wind sounds terribly loud through a microphone recording and can cause your audio to clip (distortion of waveform due to output of sound exceeding maximum capacity or 0 dB point). This includes the “wind” that comes out of your mouth when you pronounce words starting with the letter “p.” Use pop filters, windscreens, and deadcats to block wind from reaching your microphone.
5. Upgrade your microphone As much as you try to control all the noise in your surroundings, your greatest recording limitation will come from the hardware that you use. Improve your recordings by plugging in an external microphone into your camera’s microphone jack or record audio completely separately with a professional microphone.

6. Adjust your levels Before pressing the record button, see how loudly your microphone picks up the sound you wish to record. Adjust your levels (sensitivity of your microphone) until the sound sits in between -6 dBs and -12dBs. This range gives the source of your sound some room to get louder without the recorded audio getting clipped. When you first listen to audio recorded within this range, it may sound very quiet. No need to worry though because you can increase the volume later in editing.
7. Start with a sound cue if you’re planning to do some syncing in post If you’re recording separate audio that you plan to sync to your video later in editing, start your recording with a short and loud sound cue like a clap or a high pitched “beep” tone. Later, when you’re editing, it’ll be much easier for you to find the section where your video and additional audio match.
8. Get close to the sound Unless you’re aiming to record ambient sound, bring your microphone close to the source of sound you are wanting to record. The closer your microphone is to the source of sound, the lower your sensitivity setting can be on your microphone. As a result of lowering your levels, sounds you are not meaning to record will also sound fainter.
9. ADR When you need to record a scene in a loud setting where you have very little control over the noise, record additional vocals later and replace the original vocals through a process called automated dialogue replacement.
10. Record Ambient Sound Remember to record ambient sound or “room tone.” You can use these recordings to fill in the blanks if you run out of audio and also smooth out parts of your audio where you hear pops, clicks, and other unwanted noise.
