STMicroelectronics BlueCoinヒアリングとモーション検知

STMicroelectronics BlueCoinヒアリングとモーション検知プラットフォームは、STM32オープン開発環境およびオープンソフトウェア拡張ライブラリとの互換性があります（SmartAcoustic1）。 BlueCoinは、Open.AudioライブラリであるosxBlueVoice、osxAcousticEC、osxAcousticSL、osxAcousticBFを用いた設計向けに特別に設計されています。

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.
