About audio recording equipment
Having the right audio equipment makes a big difference in the quality of recorded audio.
Surprisingly, basic audio equipment can be relatively inexpensive; your equipment should include
some if not all of the following:

some if not all of the following:
Computer with a sound card
The sound card installed in your computer acts as a digital
recorder for audio.
Microphone
If possible, you should avoid using the USB microphone packaged with your
computer. Use a proper professional quality microphone cable and a stand to hold the
microphone while you are recording.

Microphone preamplifier
A preamplifier boosts the signal of the microphone. The microphone
input of your computer’s sound card probably includes a preamplifier, but it’s most likely a poor
quality one. When purchasing a preamplifier, you can choose a small mixer or a stand-alone
version. Mixers let you connect several microphones and devices to one location, and you can
adjust their volumes independently. Stand-alone preamplifiers can be better than mixers at
filtering out unwanted noises.

Speakers
The speakers that came with your computer are probably good enough for listening
to any audio you record. However, if you are working on a laptop, you must use standard desktop
computer speakers instead of the built-in laptop speakers

Headphones
Headphones are important because when the microphone is on, speakers can
cause distracting feedback. Additionally, it’s best to use closed-ear headphones that prevent sound
from leaking, which the microphone can pick up.
