3D Audio

AM3D 3D Audio is a world-class digital signal processing engine that encapsulates a large variety of features needed to simulate multiple sound sources in a 3D audio space. It creates natural 3D positional audio from both static and dynamic sources with smooth transitions between positions. It simulates a wide range of acoustical environments using high-quality reverberation. It is designed for excellent performance on resource-constrained devices such as mobile phones. The solution is purely software-based and is easily integrated into existing software platforms. All features have a very low memory- and computation footprint.

Mobile phones and other portable devices have become more and more advanced in terms of integrating features for audio/video playback and for gaming. Especially games utilise 3D graphics, and even 3D displays are now introduced on these devices. These rich visual capabilities are a core element in bringing today's products alive, but the audio performance is not moving as rapidly in the same direction. This is even though that using small devices has taught us to use headphones to get a high quality sound experience.

AM3D 3D Audio takes the audio experience into a new dimension. The engine is a highly sophisticated software engine capable of rendering 3D audio with multiple sound sources on resource constrained devices. It is based on binaural synthesis using head-related transfer functions (HRTF) and has unsurpassed 3D audio quality based on AM3D's patented technology. The high quality HRTF render produce natural 3D audio with smooth and artefact free transitions of dynamic sources - even at fast movements. To obtain the full natural 3D audio experience, high quality reverberation is added to simulate different room environments. And to the background music, Virtualizer is applied for achieving optimum sound quality. The engine supports playback through either headphones or narrow-spaced stereo loudspeakers.
