产品概述

描述

osxAcousticEC software provides an implementation for a real-time echo cancellation routine based on the well-known SPEEX implementation of the MDF algorithm. The secondary features of the SPEEX suite, namely the preprocess options and Automatic Gain Control, have been included as well. Parameters can be modified at runtime for immediate adaptation to varying ambient conditions. The osxAcousticEC library is provided in binary format, integrated in a software package providing examples running on the STM32F407 Discovery board (STM32F4DISCOVERY).
The example package is designed as an add-on for the standard STM32CubeF4 package; the library can be easily ported to any STM32F4 microcontroller with an FPU unit. The software is based on STM32Cube technology. Information regarding STM32Cube is available on www.st.com at http://www.st.com/stm32cube.
