- Signal Flow
- Order in which a signal passes through different pieces of gear
- Virtual Instrument
- Software Synthesizers - These may be reproductions of existing instruments or completely new unheard of instruments.
- Dynamic Microphone
- A moving coil is suspended in a magnetic field. The movement creates a current which is amplified.
- Plate Reverb
- A speaker is aimed at a large metal sheet suspended in a tension mount. Mics capture reflection off of the plate.
- Boundary Microphone
- captures reflections off a metal plate
- Distortion
- An inaccurate reproduction of frequencies
- Dailies
- Compilation of all footage captured for a single day. Edited and refined to make 1st cut.
- Resolving
- Speed correction necessary when converting film to digital.
- Linear Sound Design
- occurs in a specific timeline or order
- Condenser Microphone
- Contains two parallel plates-one stationary/one moving. A diaphragm is attached to the moving plate and when moved creates a voltage change that is amplified
- Parametric EQ
- enable the user to adjust every parameter of the device (frequency, amplitude, bandwidth)
- M & E Mix
- Music and Effects mix. Dialogue stem removed. Foreign studios replace dialogue track with local talent.
- Compressor
- Restricts dynamic range by making loud sounds softer and softer sounds louder
- Premixes
- Group tracks designed to minimize the number of audio tracks used at final mixdown.
- Non-Linear Sound Design
- allows sounds to be heard out of sequence.
- Foley
- Sound effects that are recorded live in sync with a picture
- Gain Staging
- Optimizing the signal level between multiple devices
- Graphic EQ
- Use sliders to boost and/or cut frequencies
- Shotgun Microphone
- An interference tube blocks sound from the sides and back of the mic allowing the front sounds to be "unmasked."
- Plug-In Formats
- VST, AU, RTAS, Direct X, HD-TDM
- Polar Pattern Diagram
- A visual representation of area, frequency response and reach.
- Noice Gate
- Used to silence a recording or instrument during very quiet sections
- Proximity Effect
- Moving a mic closer to a source creates an apparent increase of bass frequencies
- Implementation Engine/Tool
- enables the Sound Designer to become the audio programmer
- Ribbon Microphone
- Similar to dynamic mics, but use a thin metal ribbon instead of a moving coil.
- Interactive Sound Design
- Sound design that changes and adapts to a player's commands.
- 3 Sections of a Console
- Jackfield, Channel/ I/O Strip, Master Section
- Signal Routing
- Directing the signal to various destinations
- Parabolic Microphone
- uses a reflector dish to focus sound waves
- Sound Map
- a chart of the sound elements in a mix.
- Chorus
- Multiple signals played back, each signal is delayed separately which creates a subtle pitch and timing difference
- Room Tone
- General ambience of a location.
- Talk Box
- The sound is directed via a tube to your mouth where it is shaped by your mouth.
- Slate
- Provides and audio and visual cue used for sync.
- Reverb
- The reflections that occur in a room
- Attenuation
- Cutting the level
- Flanger
- Two signals are played back simultaneously. Small delays cause one of the signals to play out of sync. This causes a "comb filter effect" to be created
- Phaser
- Combined signals that exhibit phase cancellation and reinforcement
- Spotting
- Determines audio assets needed for a scene.
