Ceva adds HD audio and third party algorithm support to its BlueBud-HD wireless audio IP

www.eenewseurope.com, Jan. 04, 2022 – 

Ceva has launched a pre-configured software package for its BlueBud wireless audio IP that includes all the audio, voice and context-aware software required in premium TWS earbuds, gaming headsets, hearables, wearables and other smart audio products.

Announced at CES 2022, the SenslinQ software framework and the CEVA-BX1 DSP tool kit have also been upgraded for the Bluebud platform to streamline the addition of 3rd party DSP algorithms and to help migrate existing software from other processor architectures.

The Bluebud-HD software package takes advantage of the on-board CEVA-BX1 DSP to consolidate a wide range of optimized HD audio, voice and context-aware modules which are otherwise processed on separate DSPs or MCUs in non-CEVA architectures.

The Bluebud hardware platform has been upgraded to include CEVA's latest SIG qualified RivieraWaves Bluetooth 5.3 IP, with both Classic Audio and LE Audio, and the CEVA-BX1 audio processor, together with all the required peripherals for wireless audio, in a compact low power design, with a footprint of less than 0.5mm2 in a 22nm process technology.

Bluebud-HD also supports audio processing using 96KHz/24-bit precision, enabling many high-resolution audio standards.

The OpenAMP API provides host CPU developers with virtualized access to features in Bluebud-HD and other audio, voice and speech software available through the CEVAnet partner ecosystem. The SenslinQ framework enables Bluebud customers to consolidate all audio, voice and IMU-based contextual awareness workloads onto the CEVA-BX1 DSP rather than embedding separate DSPs for wireless and audio and results in smaller die size and lower power consumption.
