Picking The Right Microphone

You can find many diverse kinds of microphone fit your need. The differences are often described in two approaches: The technology they use and their directionality. Additionally, microphones possess a quantity of other qualities which need to be taken into account.

Microphone

When choosing on a microphone, the very first point you will need to know is what traits you will need. Following that, you can be concerned about items like size, brand, expense, and so forth.

Note: If you have not done so already, you might prefer to do some groundwork and read how microphones function initial.
Things to consider

Operate via each of these traits and figure out your needs.

Directionality

Make a decision which kind of directional pattern ideal fits your needs. Remember that it is generally better to make use of a much less directional mic inside a position close to the sound supply, than to become additional away employing a hypercardioid. For more info see microphone directional qualities.

Frequency Response

Be sure the mic’s frequency response is acceptable for the intended use. As a rule of thumb flat response patterns are greatest, but in numerous circumstances a tailored response will likely be even much better. For more info see microphone frequency response.
Impedance

The rule of thumb is: Low impedance is better than high impedance. For much more information see microphone impedance.

Handling Noise

Bear in mind that the diaphragm operates by converting vibrations from sound waves into an electrical signal. Unless the microphone has some kind of protection program, the diapragm can’t tell the distinction among a desirable sound wave vibration and any other sort of vibration (for example an individual tapping the microphone casing). Any kind of vibration at all will turn into portion of the generated audio signal.

In case your mic is likely to be subjected to any kind of handling noise or vibration, you’ll need a mic that will assist stop this noise from being picked up. Good quality hand-held mics usually attempt to isolate the diaphragm from vibrations employing foam padding, suspension, or some other technique. Low good quality mics tend to transfer vibrations from the casing right into the diaphragm, resulting within a terrible noise.

Note that lavalier mics do not typically have protection from handling noise, simply due to the fact they are as well small to incorporate any padding. It truly is for that reason essential to create positive they will not be moved or bumped.

Purchasing a Microphone

If you can afford it, it makes sense to get a selection of microphones and make use of the most suitable one for each job. In case your price range is more restricted, consider about all of the various factors you’ll need to work with the mic for and make an effort to discover anything which will do a reasonable job of as several of them as you can.

For vocalists a easy cardioid dynamic mic (like the Positive SM58) is actually a excellent starting point.
For video makers, a helpful selection can be a condenser mic with selectable directionality, so you can alter in between cardioid and hypercardioid. Should you can afford three mics, take into account a hand-held dynamic, a shotgun condenser, as well as a lapel mic.

Comparisons

In the end, sound is very subjective. You really want a mic that will supply the sound you like. An excellent notion is always to setup a contolled test. Record precisely the same sounds utilizing different mics, keeping all other elements continual.

Be sure you are comparing apples with apples; for example, never compare a hand-held cardioid and a shotgun within the identical position. If you do need to examine these mics, be sure each is placed in its optimum position.
