STMicroelectronics BlueCoin听力与运动感测

STMicroelectronics BlueCoin听力与运动感测平台兼容STM32开放开发环境和开放软件扩展库(SmartAcoustic1)。 BlueCoin专门设计用于使用Open.Audio库osxBlueVoice、 osxAcousticEC、osxAcousticSL和osxAcousticBF进行开发。

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.
