Abstract:
Comparison between novel smartphones and any other professional or consumer audio equipment reveals that phones actually provide highly sophisticated audio functions for their size and price. High quality noise reduction and echo cancellation for telephony and multichannel audio capture with wide frequency response and high dynamic range are expected, as well as loud and clear sound output for alarm tones and multimedia playback. The quality expectations keep rising, while devices should be kept small and affordable.
To start this workshop, the audio solutions in a smartphone are presented on an introductory level. After that, the panel, who are representatives of major audio component manufacturers, discuss the current audio performance requirements and present examples of state-of-the-art in audio component technology.
