Audio and Compact Media Extensions
Enabling Mobile Devices to Deliver Advanced, Three-Dimensional Audio Capabilities
Qualcomm’s enhanced audio solutions enable mobile wireless devices to deliver advanced, three-dimensional audio capabilities for a richer, fuller, and more compelling multimedia experience. Two audio-enhancing technologies, QConcert® and QAudioFX®, work together to deliver new richness to games, streaming audio, ringtones, music playback, and other applications enabled by 3G technology.
QConcert simulates a surround-sound experience by expanding audio beyond the listener’s space. This creates the effect of speakers that are larger and farther apart than they actually are on the mobile handset.
QAudioFX is Qualcomm’s enhanced gaming audio solution and enables sound sources to be placed in precise three-dimensional positions around the listener. Special audio effects that are located anywhere around, above, below or even behind the user can be aligned with 3D graphics to immerse the user into a more realistic gaming experience.
Benefits
- Delivers advanced audio to wireless devices for cinema-like sound experiences and new realism in gaming as audio effects occur in precise pinpointed locations around the wireless user
- Enables more compelling multimedia content to be delivered to users as a product- or service-differentiating opportunity, creating additional value for mobile handsets and increasing average revenue per user
- Attracts more sophisticated game players with a seamless experience comparable to those on dedicated gaming devices
Key Functionality
- Requires only stereo-format content to take advantage of QConcert’s audio expansion capabilities
- Features easy tuning for specific handset configurations with a PC-based authoring tool provided by Qualcomm with the enhanced audio solutions
- Integrates enhanced audio capabilities such as listener settings, environment settings, sound source settings, and others as made possible by Qualcomm-enabled APIs
Cost-Effective Approach to Creating Customized Ringtones and Screensavers
Sophisticated wireless handset users need more than just good sound quality and long battery life. They want a handset that reflects their personal style. Qualcomm's CMX® multimedia software is a cost-effective approach that enables developers to create customized ringtones and screensavers. Through an authoring tool provided by Qualcomm, content developers can create rich content that enables time-synchronization of MIDI-based voice, text, music, graphics and animation – delivering exciting and compelling content to the marketplace.
The CMX software is a key component of Qualcomm's multimedia suite, and is the technology behind the high-quality polyphonic ringtones and multimedia animation that global consumers have come to expect from their wireless handsets. CMX is designed for use with most Qualcomm MSM® chipsets, providing tools that deliver enhanced multimedia solutions. With CMX-based applications, operators have new revenue-generating opportunities that differentiate their product offerings and deliver superior service to their customers.
