Summary:
The dsPIC® DSC Speech and Audio Fast Forward (SAFF) tool provides users with real-time
control of Microchip’s Speech and Audio Processing Algorithms as they are running in an
embedded system application. This PC GUI tool facilitates easy tuning of Microchip’s Noise
Suppression, Acoustic Echo Cancellation, Line Echo Cancellation and Equalizer algorithms in
speech and audio applications by simplifying parametric tuning of algorithms. ..

Speaker phones
Intercoms
Teleconferencing Systems
Hands-free cell phone kits
Headsets
Any microphone-based applications
Description:
SAFF is a PC Based GUI application that simplifies speech and audio application development
with Microchip’s Speech and Audio Libraries. The tool communicates with target hardware via
Microchip’s Real-Time Data Monitoring (RTDM) protocol over an RS-232 or USB link. Users can
enable, disable and tune algorithms ( Acoustic Echo Cancellation, Line Echo Cancellation, Noise
Suppression, and Equalizer) in send and receive paths of a full duplex communication setup.
SAFF is ready to be used with Microchip’s development boards and can support custom
dsPIC30F/dsPIC33F hardware. The GUI has unique feature of generating code for selected
hardware by way of code templates. .
Features:



Supports Microchip’s dsPIC DSC Acoustic Echo Cancellation, Line Echo Cancellation,
Noise Suppression and Equalizer Libraries.
Implements typical full duplex communication signal processing chain with optimal
arrangement of algorithms.
All algorithm parameters can be controlled in real time via RTDM







The generated code from GUI tool can be ported to custom dsPIC DSC hardware
Quick Start Demonstration included with installation
Supports multiple serial communication rates for communicating with target dsPIC DSC
Uses UART and Timer peripheral on the dsPIC DSC device to implement RTDM and
MIPS measurement.
Parameters on target device can be update individually or in groups.
Simplifies the algorithm parameter tuning process
Generates code for selected hardware
