Apple Inc., formerly Apple Computer, Inc., is an American multinational corporation headquartered in Cupertino, California, that designs, develops, and sells consumer electronics, computer software and personal computers.
A description of the nominal audio signal strength resulting from a given input level and gain in an audio device or system. Level within analog audio circuitry is often measured in dBu. The instantaneous signal strength, for any nominal level, can vary from the noise floor to the dynamic ceiling. Professional “line level” typically indicates a nominal level of +4 dBu, while “consumer level” typically indicates a nominal level of –10 dBu. See also ceiling, dBu, noise floor. Compare volume.

Auxiliary data that your application can store in a QuickTime movie, track, or media structure. The user data is stored in a user data list; items in the list are referred to as user data items. Examples of user data include a copyright, date of creation, name of a movie’s director, and special hardware and software requirements. See also user data item, user data list.

Signal-to-noise ratio. The range, expressed in decibels, between a nominal signal level and the noise floor. Compare dynamic range.
Industry:Software; Computer
A Component Manager–based Simulator that adds an audio feature to a Mac OS X application. Audio units can provide effects such as filtering and reverb, MIDI-based music synthesis, audio data format conversions, mixing, panning, sound generation, and audio playback. Unlike application-specific plug-ins, audio units are available systemwide. Multiple instances of a single audio unit can run simultaneously.
Industry:Software; Computer
Computer object code that is processed by a virtual machine. The virtual machine converts generalized machine instructions into specific machine instructions (instructions that a computer’s processor can understand). Bytecode is the result of compiling source language statements written in any language that supports this approach. The best-known language today that uses the bytecode and virtual machine approach is Java. In Java, bytecode is contained in a binary file with a .class suffix. (Strictly speaking, “bytecode” means that the individual instructions are one byte long, as opposed to PowerPC code, for example, which is four bytes long.) See also VM.

(1) For databases, a mechanism that connects your application to a particular database server. For each type of server you use, you need a separate adaptor. WebObjects provides an adaptor for databases conforming to JDBC. (2) In WebObjects, a process (or a part of one) that connects WebObjects applications to an HTTP server.

Unicode is an ISO standard for universal worldwide character encoding developed by a consortium that includes Apple. Unicode has enough capacity to handle unique encodings for all characters available in all scripts, including the 2-byte script systems such as Chinese, Japanese, and Korean.
