Introduction to Sound Recording Microphones
A microphone is a transducer that changes acoustical energy (sound waves) into electrical
energy (current)
Three types of microphones:
- Dynamic
- Shure SM58 (most popular live microphone)
- Can’t respond to high frequencies
- Condenser
- Uses two electrically charged plates
- Requires power
- Affected by humidity and temperature
- Ribbon
- Has high frequency response response
- Very fragile
Other types:
- Carbon Microphone (old microphone)
- Copperphone
- PZM (piezo)
- Uses crystal that reacts to pressure
- Older microphones are meant to sound a certain way
Rule of thumb (yin-yang)
- Choose a microphone at captures the opposite sound that you want
- Balances out the sounds
Every microphone has a distinct sound
- The different types will have different sounds, and even if the microphone are the same
type, they could still make a distinct sound
- Know what the sound of the microphones are
Microphone selection and placement are an art form
- There are no “right” or “wrong”
-
Pickup characteristics as a function of working distance
- Distant placement
- Placement about three feet or more of the sound source
- Allows the sound to develop fully before being picked up by the mic
- Will always have phase cancellation
- Close placement
- Placement of about one inch to three feet of the sound source
Document Summary
All things important are highlighted , things related are highlighted in different colors. A microphone is a transducer that changes acoustical energy (sound waves) into electrical energy (current) Older microphones are meant to sound a certain way. Choose a microphone at captures the opposite sound that you want. The different types will have different sounds , and even if the microphone are the same type, they could still make a distinct sound. Know what the sound of the microphones are. Microphone selection and placement are an art form. Pickup characteristics as a function of working distance. Placement about three feet or more of the sound source. Allows the sound to develop fully before being picked up by the mic. Placement of about one inch to three feet of the sound source. Can edit the recording for post production. Also because of the ability to record on multi track.
