A Quick Guide to Microphones

22 Comments



Microphones. Pretty much every musician has to deal with
them at some point or another. How do you actually know which one to use,
and how to use it? To start, there two basic types of mics that
you might use: Moving coil microphones, which are most commonly called dynamic mics, and capacitor microphones, which are most commonly known as condensers. Dynamic mics are known for being rugged, affordable
and all around useful. (Not bad at all.) They don’t have the crystal clear, full bandwith
operation of condensers, but this is actually often a good thing, such as when you’re recording
certain types of drums, guitar amps, or other acoustic instruments. Condensers are good for vocals, generally
somewhat fragile, and usually more expensive. They are known for their ability to capture
fine detail. Condensers require some current to work. This is phantom power, which is commonly represented
by a button or switch labeled as +48V. Microphones are a type of transducer. The transducer is something that converts
energy from one form to another. In this case, they’re taking sound waves and
turning them into electrical energy. Though different mics work in slightly different
ways, they all have a diaphragm. The diaphragm is a thin piece of material,
often mylar or some form of metal, and often even gold-plated, in the case of condensers. When sound strike the diaphragm, it causes
it to vibrate, and this passes energy to the rest of the microphone’s components. These vibrations are converted to an electrical
current which becomes the audio signal your interface uses to capture and playback sound. Generally speaking, smaller diaphragms are
more sensitive and react faster than do large diaphragms. So large diaphragm mics are often better for
voice and vocals, since they don’t pick up as much annoying lip and mouth sounds. Microphones have a directionality, commonly
referred to as their polar pattern. Make sure your mic is pointed in the right
direction. Most small diaphragm mics are known as “front
address,” which means that you face them directly at whatever it is you’re trying to record. Large diaphragm mics are commonly front or
side address, which means you have to be sure you’re pointing them in the right direction. One way to tell is that in most cases the
company’s logo is on the front of a side-address microphone. Microphones create a very weak signal, so
you need what’s called a preamp. Your audio interface likely has at least one
of them. These will amplify the very low level electrical
signal to a useful level, and it makes it possible for your audio interface to sample
the fluctuating voltages more accurately. So there you go. Chose the right mic, face it in the right
direction, plug it into a preamp and then you’re ready to start capturing the sounds
of the world all around you.

    Thanks man 🙂
    A buzzer could also act as a microphone, the piezoelectric disc inside it. 🙂

    For what purpose microphone is used reocord sound,play sound, or for both?

  10. Scott Hoverman says:

    So with a condenser, would I need BOTH 48v phantom power AND a preamp? Or would just 48v phantom be enough?

  11. Gabriel Köbler says:

    Very fun and informative Video, nice!

  12. Rock Candy says:

    1:15 Hey, don't pull a bill wurtz on me now.

  13. Rock Candy says:

    So i'm guessing condensers are better for voice acting, even more spesifically larger ones. Right?

  14. areamusicale says:

    1:16 was that a Bill Wurtz parody ? 😀

    quack

    There every where.

  21. Quentin McKay says:

    Perfect video. Short. Informative. Humorous. 10/10. Thank you!

  22. Beyond Edge says:

    Thanks I loved it I'm also a sound engg. And want to create this kinds of videos so how did you made this video like how did you edit it..!!!🤗🤗🤗
