| the branch of phsyics that studies sound | physics |
| sound presssure levels are measured in | decibels |
| created when you represent the characteristics of a sound wave using numbers | digital audio |
| digital audio is said to be ____ because the quality of audio is based on the quality of your recording and not the device on which your end user will play the audio | device independent |
| when the value of each audio sample is rounded off to the nearest integer. If the amplitude is greater than the intervals available, clipping off the top and bottom of the wave occurs | quanitzation |
| removing dead air or blank space from the front of a recording any any unecessary time off the end | trimming |
| removing extraneous noises that can enter a recording | splicing |
| the process of reducing the amount of samples in a file | resampling/downsampling |
| allow you to modify a recording's frequency content so that it sounds brighter (more high frequencies) or darker (low rumbles) | digital equalization |
| let you alter the length in time of a sound file without changing in pitch | time stretching |
| determines the accuracy with which a sound can be digitized | audio resolution |
| a communication standard developed for electronic musical instruments and computers, allows music and sound synthesizers to communicate with each other by sending messages along cables connected to devices | MIDI (musical instrument digital interface) |
| method used to store the bits and bytes that describe a sampled waveform sound for consumer-grade music CDs | linear pulse code manipulation (LPCM) |
| developed so that you can put several recording sessions of music or data onto a single CD-R disk | CD-ROM/XA (extended architecture) |
| software that compresses a stream of audio or video data for storage or transmission, then decomposses it for playback | codec |
| says there is an acceptable minimum level of adequacy that will satisfy the audience, even when that level may not be the best that technology, money, or time and effort can buy | vaughan's law of multimedia minimums |
| a place where data is stored temporarily | buffer |
| sound pressure levels are measured in | decibels (dB) |
| the actual representation of a sound, stored in the form of thousands of individual samples that represent the amplitude (loudness) of a sound at a discrete point in time | digital audio data |
| how often the samples are taken | sampling rate |
| sample sizes are either ___ bits or ____ bits | 8, 16 |
| the value of each sample is rounded off to the nearest integer | quantization |
| a shorthand representation of music stored in numeric form | MIDI |
