Rat Attack will use multi-track XA-ADPCM for music on PlayStation, allowing a very large number of themes, unique for each level theme, while maintaining CD-audio quality.
At certain points in the game (for example, when the timer countdown reaches zero and the game speeds up) the music will change to be faster, providing a change of feel and putting additional pressure on the player.
On N64, Rat Attack will make use of MIDI functionality to provide a large number of tracks, without the need for CD storage. This will also allow us to speed up/slow down the music, and to have it change dynamically according to the in-game action. This feature will be exclusive to the N64 version.
Overall, music in the game will have a light-hearted, cartoon-like feel.
Each location in the game will have its own set of music sequences and sound effects, which will further add to its own individual appeal.
Speech will also be used in the game to help bring out the character and personality of the cats. A cat will have its own piece of speech for the end of a level, as well as one for the 'special attack'.
There will also be some speech for the rats, to be used minimally to add character (each cat will also have a variety of other sound effects- meows etc).
Sound effects will play an important role in bringing a 'comic' feel to the game. A cat will speak a little phrase at the end of a level.
