STMicroelectronics BlueCoin 청각 및 모션 감지 장치

STMicroelectronics BlueCoin 청각 및 모션 감지 플랫폼은 STM32 개방형 개발 환경 및 개방형 소프트웨어 확장 라이브러리(SmartAcoustic1)와 호환됩니다. BlueCoin은 개방형 오디오 라이브러리 즉, osxBlueVoice, osxAcousticEC, osxAcousticSL 및 osxAcousticBF를 사용하여 개발하기 위해 특별히 설계되었습니다.

osxBlueVoice is a Voice-over-BLE vendor specific profile library for STM32 and BlueNRG.

osxAcousticEC is an Acoustic Echo Cancellation that removes a far end signal from the audio acquired by a microphone.

osxAcousticSL is a Sound Source Localization that estimates the angle of arrival of audio signal.

osxAcousticBF is beam-forming that implements a directional virtual microphone.
