Network Audio Player
Introduction
A Network Audio
Player for playing digital audio files streamed over Ethernet from a remote
computer.
Digital Audio is simply data,
and
can
be
handled
as such up to the moment it is converted into the analog domain with a DAC.
The
DAC output will connect directly to the VMOS Line Driver's input
transformer. Volume control with be accomplished digitally thus
providing a minimal path system.
The Network Audio
Player is based on the
Cirrus EP9315A
ARM9 32 bit processor running embedded Linux.
EDB9315A Development Board with
Opie Player
Initial work makes
use of the cost effective EDB9315A development board and once I have some
specific player software written I will layout a dedicated 6 layer PCB.
Although envisioned as a network device, the EP9315A supports an
IDE interface for a local ATA hard drive and CD-ROM may be added
for development.
