GS2011M Music
Application Development Kit
High Quality Streaming Music over WiFi
PRODUCT OVERVIEW
GainSpan Music ADK is a development platform enabling
customers to build high quality wireless music applications with
GS2000 Wi-Fi modules. By integrating the major hardware and
software components for a WiFi music streaming solution, this
platform facilitates fast time to market in a customer development
effort.
Targeted applications for this platform include wireless speakers,
bookshelf / tabletop speakers, sound bars, and variety of other
systems where customer would like to add music streaming
functionality. In addition to support for major audio codecs, the
platform also integrates DSP functionality and advanced audio
post-processing functions providing excellent sound quality.
GainSpan’s software stack establishes easy connectivity between
mobile device and the wireless speaker. In addition, the platform
also supports major streaming protocols such as WiFi
Direct/Miracast, AirPlay, DLNA etc.
MUSIC ADK FEATURES
The following Music ADK features include the following:
•
Streaming of high bit rate uncompressed or compressed
multichannel audio streams. 24-bit high resolution audio
streams and sampling rates of up to 192kHz are
supported with the development platform.
Longer range than other wireless technologies for music
streaming within the home.
Ease of provisioning: ADK can be set up simply and easily
from a Smartphone or Laptop through the innovative
Limited AP mode or with WiFi Protected Setup (WPS 2.0).
Integration of home networking protocols including WiFi
Direct/Miracast, AirPlay, and DLNA.
