The sixth thing you need to consider is the microphone techniques. These are the methods or skills that you use to manipulate or optimize the microphone and the sound. Some common microphone techniques are proximity effect, stereo recording, phase cancellation, and EQ. Proximity effect is the phenomenon that the microphone boosts the low frequencies of the sound when it is close to the sound source. You can use this effect to create a warmer or fuller sound, or to avoid it by moving the microphone away. Stereo recording is the technique of using two or more microphones to record the sound in a way that creates a sense of width, depth, and realism. You can use different stereo recording methods, such as XY, AB, ORTF, or MS, depending on the desired effect. Phase cancellation is the phenomenon that the microphone reduces or eliminates the sound when it receives two identical signals that are out of sync. You can avoid this problem by placing the microphones in phase, or use it creatively to create special effects. EQ is the technique of adjusting the frequency balance of the sound. You can use EQ to enhance or reduce certain frequencies, or to correct or shape the tone of the sound.
