ADPCM 1.00
(Code S001-94-C25-100)
by S.E.E.D.

Software Overview

TMS320C2x implementation of CCITT G.726 reccomendation, it accepts linear 14-bit data. It is 
possible to use it to compress voice files previously recorded, or to compress voice data in 
real-time. Translate received data into 4-bit ADPCM format and vice versa.

Features and Benefits

•	14-bit linear I/O
•	Real-time half duplex

Processor and System Requirements

•	TMS320C2x-based systems, 40-MHz or faster. Needs A/D and D/A converter (8-kHz sampling frequency) 
for real-time operation. Doesn't need converter to compress recorded file.

Usage Limitations or Performance Considerations

•	Real-time for 8-kHz sampling frequency. Half-duplex only, now.
•	Product reliability: Complies with the G.726 standard.

Availability

Written by S.E.E.D. and available 2Q/95.
