Audio For Mobile Devices by Martin Wilde
Over the past few years, many advances have been made in audio for console and PC games, for good reason: the hardware is evolving quickly and now supports impressive audio capabilities. In contrast, the audio capabilities of cell phones and other mobile platforms are limited. Fortunately the functionality of these devices is growing by leaps and bounds, and that's beginning to offer some interesting possibilities for game developers. This article outlines the current and emerging audio technologies available for games in the mobile marketplace, via a survey of mobile audio development, authoring and player technologies from a high-level perspective.

Audio Prototyping with Pure Data by Leonard Paul
Interactive game audio requires combining content and code. Unfortunately, composers often have little control over how the code works and thus how the audio will sound in the final game. What's needed are tools that let the composer prototype the audio and show the programmer. One such tool is Pure Data, an open source program that is extensible, powerful, and, well, free.

Breaking the 64 Spatialized Sources Barrier by Nicolas Tsingos, Emmanuel Gallo and George Drettakis
Spatialized soundtracks and sound effects are common in today's games. But one area that is still holding back more realistic audio is the limited number of available 3D audio hardware channels. Some might wonder if more than a 64 sources is really needed, but when you start adding up the number point sources in say, a train, you begin to understand that there are situations that demand more than hardware can deliver.

Design With Music In Mind: A Guide To Adaptive Audio For Game Designers by Guy Whitmore
Game designers are learning that music doesn't have to be merely a detached backdrop to the action on screen - it can ebb and flow, adding emotional depth and soul to scenarios and help maintain the suspension of disbelief that is so crucial for players. In this article, Whitmore explains ways that game designers can work more closely with composers to achieve a more integrated soundtrack for games, and describes tools that can help the process.

Introducing the Interactive XMF Audio File Format by Linda Law
Interactive XMF is an emerging cross-platform audio standard that will help put creative and technical control in the hands of the right people: the composers. Developed by the MIDI Manufacturers Association, IXMF will decrease a game's time to market, improve audio quality, and will promote skills in composers and programmers that transfer from company to company. Learn about this emerging format and what it will do for game audio in the coming years.
