Application note

How to implement a vocoder solution using STM32 microcontrollers

Introduction

This application note describes the vocal codecs (vocoder) available for STM32 32-bit

ARM® Cortex® microcontrollers. The supported codecs are G.711, G.726, IMA-ADPCM and

Speex.

It comes with examples of implementation on STM32F4DISCOVERY (referred as

DISCOVERY board hereafter), STM322xG-EVAL and STM324xG-EVAL (referred as EVAL

boards hereafter).

These examples are developed in such a way that they can be easily ported to any other

STM32 microcontroller and board.

The vocoder firmware package is provided upon request, for more details please contact

your local ST sales representative.
