Attack time refers to the amount of time the sound must occur before unmuting. You can change them if you’re not getting your desired effect, or want to get the best audio possible. The other three settings should be fine with their default settings. If you’re using a mechanical keyboard it might be difficult to cut out the entirety of your keyboard sound depending on the switches being used. If set properly you should only be able to see the mic activating when you are speaking. You can use the Audio Mixer preview to help you get these settings correct. This should be just below your normal vocal volume. The open threshold amount determines how loud audio needs to be before being unmuted. If the audio being picked up is below this point you won’t be able to hear it on stream or recordings. The close threshold determines the cutoff point as to where the audio will be muted.
The name says quite a lot about what the Noise Gate filter does, it decides what noises should be transmitted and which shouldn’t. Whereas the threshold indicates at what level (in dB) the compressor will activate. Ratio indicates how strong the compression is. The two main settings that you want to be focusing on is the threshold and ratio. It can be beneficial in situations where you do not want a signal coming from a 90° angle to bleed into the microphone.Step 8: Adjust the settings to what will best suit your audio, again this will take some experimenting to get right. This makes unidirectional microphones effective at isolating the desired sound from both unwanted sound and ambient noise.Ī bidirectional microphone (with figure-8 pattern) picks up the sound from in front of the microphone (at 0°) and from the rear (at 180°), but not the side (at 90° and 270°). Unidirectional microphones are most sensitive to sound arriving from directly in front (at 0°) and less sensitive in other directions. It will be especially useful in good sounding rooms. Therefore, the microphone need not be aimed in a certain direction. This means it picks up sound evenly from all directions. The omnidirectional microphone has equal sensitivity at all angles. It is easy to get a good signal as the cardioid pattern blends out a bad sounding room, a noisy fan in the background, etc. You can use this for most recording applications. This isolates it from unwanted ambient sound. The most commonly used pattern is most sensitive at 0° (the front) and least sensitive at 180° (the back).
The most common types are: Cardioid, Omnidirectional, Unidirectional, Bidirectional.
The pick-up pattern of a microphone is the sensitivity to sound relative to the direction or angle from which the sound arrives, or how well the microphone "picks up" the sound from different directions.
