General MIDI

A standard set of 128 sounds for MIDI sound cards and devices (synthesizers, sound modules, etc.). By assigning instruments to specific MIDI patch locations, General MIDI provides a standard way of communicating MIDI sound.

MIDI's small storage requirement makes it very desirable as a musical sound source for multimedia applications compared to digitizing actual music. For example, a three-minute MIDI file may take only 20 to 30K, whereas a WAV file (digital audio) could consume up to several megabytes depending on sound quality. See MIDI.

gold code

Program source code that is ready for commercial distribution. When a vendor says its product "has gone gold," it means the source code has been compiled into an executable program ready for sale. The next steps are to turn it into an installable product and create a CD or DVD "golden master" (GM) for the disc manufacturer or into a file for Web downloads. See build and RTM.
