About This Book

This document describes how to use and execute the demonstration application that is preprogrammed into the Symphony
SoundBite board. This application doubles as the board test software during manufacture of the board. The details of the
board test procedure and how to build the demonstration application from the source files are also included. The source code
for the demonstration application is provided separately.

Audience

This guide is intended for users of the Symphony SoundBite audio development board.

Organization

This document is organized into the following chapters:
Chapter 1 Describes the Symphony SoundBite board.

Chapter 2 How to run the preprogrammed demonstration application.

Chapter 3 How to perform the factory board test procedure.

Chapter 4 How to build the demonstration application from the source files.

Chapter 1 About Symphony SoundBite

1.1 Hardware Features

Built around a single DSPB56371 device, the Symphony SoundBite is an inexpensive, feature-packed solution for audio
digital signa l processing.

• Th e Symphony SoundBite supports the simultan eous input and output of 8 channels of analog audio (or 6 channels
of analog with digital stereo optical S/DIF) through the eight 3.5 mm stereo jacks on the board. Sample rates of up
to 192 kHz are supported with th e four 24-bit stereo codecs provided on the board.

• A seri al I
stand-alone configuration (the DSP application code can be stored in the EEPROM).

• An 8-position DIP switch and 9 LEDs are connected to GPIO pins on the DSP and are available for user
interaction and indications. An expansion header is provided to facilitate off-board expansion.

C EEPROM provides non-volatile storage for the DSP, as well as allowing the board to operate in a

• An on-board USB interface provides low-level JTAG/OnCE debugging capability. The USB interface also
provides high-level SPI and I
jack, but optimum audio performance requires the use of an external power supply.

• The anal og inp u ts and outputs are considered t o be line- level. Since two different types of codecs a re used , there i s
a slight difference in the full-scale maximum input and output voltages between them. Please refer to the data
sheets for the AKM codecs AK4556 and AK4584 for more information.

NOTE: Although headphones may be plugged into the output jacks and sound may be heard in them, th er e is n o
headphone amplifier built into the codecs nor is one provided on the Symphony board. Clipping will occur at higher output
levels due to the load headphones present to the codec outputs. An external amplifier should be employed when using
headphones.
