| Word | Description |
| dB Scaling | An option to display the graph view Y axis in logarithmic scaling when representing properties that are measured in decibels. |
| dBFS | Decibels full scale. Decibel amplitude levels in digital systems which have a maximum available level, such as PCM encoding. |
| DC Offset | The Direct Current represents the center of a waveform of a sound. The offset represents the percentage away from the 0.0 point where the center of a waveform lies. |
| Default Work Unit | XML files that contain all the information in your project related to the specific element for which they were created. For example, the Default Work Unit.wwu file for Events contains all the information related to events, and the Default Work Unit.wwu file for States contains all the information related to states, and so on. Default work units are created when the project is created. |
| Definition File | Tab-delimited text files that list all the events in a game, classified by SoundBank. Special keywords can also be included to define the types of project elements that will be packaged in the SoundBanks. |
| Delay | An audio effect plug-in that adds echoes by delaying an audio signal for a specified period of time. |
| Depot | A central repository of files on the Perforce source control server. It contains all versions of all files ever submitted to the server. |
| Dialogue Event | A method to trigger audio in game using a set of rules or conditions expressed in arguments and argument values that match the possible conditions in the game. These argument values are arranged into argument paths and then assigned to an object in Wwise. When a dialogue event is called by the game, the game matches its current situation with those defined in the dialogue event and the appropriate piece of dialogue is played. |
| Dithering | The noise added to a signal prior to quantization which reduces the distortion and noise modulation resulting from the quantization process. Although there is a slight increase in the noise level, spectrally shaped dither can minimize the apparent increase. The noise is less objectionable than the distortion, and allows low-level signals to be heard more clearly. |
| Dry Signal | Output that consists entirely of the original, unprocessed signal. |
