STMicroelectronics BlueCoin Hör- und Bewegungserfassung

Die STMicroelectronics BlueCoin Hör- und Bewegungserfassungsplattform ist mit der STM32 offenen Entwicklungsplattform und offenen Software-Erweiterungsbibilotheken (SmartAcoustic1) kompatibel. Die BlueCoin ist speziell für die Entwicklung unter Verwendung von Open.Audio-Bibliotheken wie osxBlueVoice, osxAcousticEC, osxAcousticSL und osxAcousticBF konzipiert.

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.
