And to support applications that need advanced audio management, MT2533D integrates a DSP that comes with 128KB IRAM, 250KB DRAM, and 96KB SRAM for various speech enhancement algorithms. This DSP delivers native Dual Microphone Noise Reduction (DMNR) technology and supports third-party software for a voice wake-up command.

MT2533D also supports A2DP, HFP, Advanced Wireless Stereo, and MP3 local playback. Besides, it can also act as the MCU for other applications, which can include biosensing. In addition to audio features, the new chip also offers display and camera interfaces, and can work with additional connectivity, such as Wi-Fi, using the SDIO feature. The chipset will be available to device makers in Q1 2017, so we can expect audio product makers utilize the technology to produce smart wireless audio devices.
