Choosing the appropriate microphone depends on:
-The specific type of recording needed
Choose the necessary cables.
-Certain cable types are needed to conect all of the equipment correctly
-The type of microphone selected
-The recording device being used
-Goal to record the original audio as effectively as possible.
Audio Editing Software
Captures audio from the original source and imports it into the editing software
Write a script that effectively conveys the intended message to the audience. Consider the following:
-The accepted vernacular of the target audience
-The readers (performers) of the script
-Record audio from original source
-Maintain audio levels throughout recording to ensure quality
-Use an audio editing software to edit the recorded audio
-Editing previously recorded audio
-Check for errors and functionality
-Revision based on test results
-Preview the final version
-Requires an outside power source (phantom power)
-Results in a high quality signal production
-Commonly used to capture a person's voice or a musical instrument in a studio
-Does not require an outside power source
-Audio signal strengthened by an audio board or other amplifier
-Commonly used to capture audio during live production
-Typically attached to the necktie or shirt of the user
-Used by performers on television or stage because their small size makes it easy to hide
-Produce a relatively good sound quality
-Usually long and skinny in appearance
-Best for recording from a distance
-Commonly found on high-end video cameras for capturing sound from the recording
-Also referred to as a "boom" microphone
An advantage to USB is that there are many interfaces designed to run on USB bus power (rather than an external power supply)
-Works well for mobile recording with your laptop
-The best audio quality, making it common in the professional industry
-Has a push-button locking system that keeps it from easily being unplugged.
-Very commonly used for microphones
-Found on virtually every consumer audio device
-Relatively poor audio quality
-Number of rings around the plug indicate of cable is mono (one ring) or stereo (two rings)
1/4" Phono Cable
-Widely used to connect speakers, amplifiers, and guitars
-Similar to mini plug with the rings indicating the number of channels
-Better audio quality when compared to the mini.
Microphone Pick up Patterns
Depending on the type of recording that is desired and the location of the performers, different microphone pickup patterns record the sound in varying methods.
Omnidirectional pickup pattern
-Captures sound from all directions
-Useful for capturing sound from all parts of a room
-Commonly found on consumer video cameras
Cardiod pickup pattern
-Audio sources in the front of the microphone and very close to the sides are captured
-Very little sound is picked up from behind the microphone
Bidirectional pick up pattern
-Captures sound from in front of the microphone and behind it
-Very little sound it picked up from the sides
-Good microphone to use when recording a two-person conversation.
Shotgun pickup pattern
-Captures sound from a pointed direction in a narrow range
-Useful for recording sound from long distances
-Very little sound is picked up from the sides or behind the microphone
-Clicking and dragging the playhead of an audio project through the timeline to get to a particular section
-The user is able to hear the audio while scrubbing, making navigation of the project more efficient
-An editing feature that lowers the volume of a particular track when another audio source is present
-Commonly used for voiceovers with background music
The process of adjusting the different levels (bass, treble, mid-tones, etc.) in an audio recording in order to produce the best sound.
Adding gain to audio will increase the level of the output signal using power from an amplifier; increases the voltage output of the signal.
The process of making sure all of the audio levels in a project are at a consistent level and sound good together.
Live Audio Techniques
When working with live audio a mixing console is typically used
Each microphone or audio input is connected to the mixer to be adjusted in a channel
No matter how many channels an audio mixing board has, each channel works the same way.
-The sound enters through the audio gain area
-The sound is edited with the EQ and the Aux section
-The volume control for the channel before it is mixed is the fader
-The gain controls how much audio is coming in, and the fader controls how much sound is coming out
-The gain should be set, then EQ and Aux adjusted for a proper sound
-To control the volume of that channel after Gain, EQ and Aux are set, only the fader should be used. Adjusting the gain will cause the EQ and Aux to be re-calibrated
-Once each channel is set they all are fed into a master area
-From the master area; mixed sound goes to performers headsets, the mixers headphones speakers and recording devices
-It is important to watch the VU meter in the master section of the mixing console.
-If the volume goes into the red area often, or remains in the red area, there is the possibility of audio distortion.
