  1. Digital Audio Mics and connections

  2. Microphones Condenser: microphone consisting of a capacitor with one plate fixed and the other forming the diaphragm moved by sound waves 

  3. Microphones Dynamic: A microphone whose sound pickup device consists of a diaphragm that is attached to a movable coil

  4. Microphones Piezo electric:contain ceramic or quartz crystals linked with a diaphragm or directly exposed to acoustic waves. This arrangement reduces the electrical noise and output impedance

  5. Microphones Wireless: is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated.

  6. Digital AudioEquipment Speakers: electroacoustic device, often housed in a cabinet, that is connected as a component in an audio system, its function being to make speech or music audible. (surround sound, mono, etc.)

  7. Digital AudioEquipment Headsets: a device consisting of one or two earphones with a headband for holding them over the ears and sometimes with a mouthpiece attached. (which kind will help you accomplish your objective?)

  8. Digital AudioEquipment CABLES AND CONNECTORS The worst audio quality. The choice of modern audio players and consumer electronics. This type of audio connection typically offers a decent signal for no-professional applications. TRS in the name stands for Tip, Ring, Sleeve. The number of rings tell the user if the plug is stereo (two rings) or mono (one ring). The best audio quality. The choice of profession applications. This type of audio connection typically offers an analog signal. The button at the top of the connector prevents the cable from accidentally being unplugged. The cable cannot be removed without pushing this button.

  9. Digital AudioEquipment CABLES AND CONNECTORS

  10. Digital AudioEquipment CABLES AND CONNECTORS This plug is used in an audio application. It connects an audio board to a computer. It is also used to connect a computer to many many things.

  11. MicrophonePickup Patterns Omnidirectional: Sound that pick up from all directions

  12. MicrophonePickup Patterns Unidirectional: A pick-up pattern which is more sensitive to sound arriving from one direction than from any other. Cardioid Hypercardioid

  13. MicrophonePickup Patterns Cardioid Cardioid - heart shaped pick up pattern (uni-directional with some on the side) Great for interviewing people with some pick up of background noises for “atmosphere”.

  14. MicrophonePickup Patterns Hypercardioid = Small Shotgun Mic Good for recording things from extreme distance… football games

  15. MicrophonePIckup Patterns Shotgun: type of pickup pattern that is highly directional. captures sound in the direction the microphone is pointed. subject does not have to be in close proximity to the mic. Good for recording things that are very far away.

  16. MicrophonePIckup Patterns Bidirectional: will capture sound from the front and back of the diaphragm. Good for stereo recording or interviewing in stereo.
