Sound
Guidelines
1. Introduction
This document outlines the sound settings guidelines for the Nintendo GameCube™.
Please also refer to the Nintendo GameCube
TM
Function Reference Manual, which documents each of the
APIs in detail.
2. Setting the Sound Output Mode
2.1 About the two sound modes
The sound output mode for the Nintendo GameCube
TM
is determined by two sound modes.
2.1.1 Main Sound Mode
Sound settings can be specified in the Initial Program Loader (IPL) Option Screen of the
Nintendo GameCube
TM
. These sound settings are preserved within the Nintendo GameCube
TM
, itself. This
is called Main Sound Mode. The only settings that can be saved as Main Sound Mode are stereo and
monaural.
2.1.2 Sub-Sound Mode
The only settings that can be saved as Main Sound Mode are stereo and monaural. If the game supports
other extended sound modes (such as headphone mode or surround mode), and the game developer
wishes to reproduce the most recent game-play environment when restarting the game, Main Sound Mode
is not sufficient for representing these additional sound modes. These additional sound modes must be
saved as data on the Nintendo GameCube
TM
Memory Card. This type of sound mode is called a Sub-
Sound Mode.
