Application note
Vocoder demonstration using a Speex audio codec
on STM32F101xx and STM32F103xx microcontrollers

Introduction
This application note describes how to implement the codec Speex software on the
STM32F101xx and STM32F103xx microcontrollers to build a vocoder application.
Speex is a free audio codec dedicated to speech encoding and decoding. It provides a high
level of compression with a good quality of sound. That makes it a high-performance
solution for any application using message playb
