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.
