Summary
The dsPIC Digital Signal Controller (DSC) G.76A Speech
Encoding/Decoding Library performs toll-quality voice
compression and voice decompression. The library is an
implementation of the ITU-T G.76 (Annex A) standard,
on the dsPIC DSC. The encoding algorithm used is
Adaptive Differential Pulse Code Modulation (ADPCM).
The compression can be configured by the user to be
either 3.:1, 4:1, 5.33:1 and 8:1, corresponding to
output data rates of 40, 3, 4 and 16 kbps respectively.
A well-defined API makes the library easy to integrate
with the application.
The G.711 library is suitable for both half-duplex and full-
duplex systems. Some key applications include:
•

A flexible analog interface gives your design several
options to consider. The speech encoder samples
speech at 8 kHz using either an external codec or the on-
chip 1-bit Analog-to-Digital Converter (ADC). The speech
decoder plays decoded speech through an external
codec or the on-chip Pulse Width Modulator (PWM).
Storing compressed speech for playback requires 8 KB of
memory for each second of speech.
A PC-based Speech Encoder Utility program creates
encoded speech files for playback. Encoded speech files
are made from either a PC microphone or existing WAV
file. Once the encoded speech files are created, they
are added to an MPLAB® IDE project, just like a regular
source file, and built into the application.
