CEVA, Inc. announced that it has enhanced the software offerings and tool kits for its highly successful Bluebud wireless audio platform with the addition of Bluebud-HD, a pre-configured software package that includes all the audio, voice and context-aware software required in premium TWS earbuds, gaming headsets, hearables, wearables and other smart audio products. The company also announced that its SenslinQ software framework and the CEVA-BX1 DSP tool kit have been upgraded for the Bluebud platform to streamline the addition of 3rd party DSP algorithms and to facilitate the easy migration of existing software from other processor architectures. Host CPU application developers benefit from the OpenAMP API for virtualized access to the feature sets enabled by 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. 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 22nm.

Bluebud-HD also supports audio processing using 96KHz/24-bit precision, enabling many high-resolution audio standards. The fully integrated software package includes: CEVA's ClearVox™, enhanced to support up to 48KHz sampling rate, for super wideband voice conversations; VisiSonics RS3D™ software for an immersive 3D audio experience; CEVA's MotionEngine™ Hear software for accurate head tracking, in-ear detection, and tap control; Personalized hearing tuning for adaptation to each listener's hearing; LHDC high definition audio codec; CEVA's SenslinQ DSP software framework for plug and play power efficient native DSP algorithms; Bluebud-HD SDK.
