Enabling audio brands to develop high quality, low-latency products such as standalone or multi-room wireless speakers, AV receivers and sound bars, Microchip has released its 4th gen JukeBlox platform. The JukeBlox 4 SDK, in combination with its CY920 WiFi & Bluetooth Network Media Module, includes next-gen dual-band WiFi technology, MultiZone/multi-room features, AirPlay and DLNA connectivity.

The certified CY920 WiFi and Bluetooth Network Media Module is based on Microchip’s DM920 WiFi Network Media Processor, which integrates 2.4 and 5GHz 802.11a/b/g/n WiFi, high-speed USB 2.0 and Ethernet connectivity. Speakers using the 5GHz band avoid the RF congestion found in the 2.4GHz band, resulting in fewer audio drops and the ability to use a greater number of speakers in multi-room/whole-home audio systems.

The DM920 WiFi Network Media Processor also features integrated dual 300MHz DSP cores that can reduce or eliminate the need for costly standalone DSP chips. A PC-based GUI simplifies the use of a pre-developed suite of standard speaker-tuning DSP algorithms, including a 15-band equaliser, multiband dynamic range compression, equaliser presets and various filter types. Engineers with no DSP code-writing experience can easily implement DSP into their designs, while experienced DSP engineers can harness the full power of an industry-standard DSP architecture.

With JukeBlox 4, product developers can build solutions equipped to directly stream cloud-based music services such as SpotifyConnect, Qobuz, Rhapsody, Deezer and many others while using mobile devices as remote controls. This allows mobile devices to move anywhere in the Wi-Fi network without interrupting music playback, and greatly increases battery life. JukeBlox technology continues to offer seamless cross-platform support for iOS, Android, Windows 8 and Mac, along with a complete range of audio codecs and ease-of-use features to simplify network setup.

In addition, the SDK has whole-home multi-room functionality for simultaneous audio streaming to, and control of, multiple JukeBlox platform-enabled devices in the home. The combination of hardware and software technology improves synchronisation and reduces network bandwidth use to achieve a robust audio streaming experience.

The JukeBlox 4 SDK, paired with the JukeBlox CY920 module, is available for sampling and volume production.
