This is my first project with VLSI decoder
VS1003 - "portable" MP3/WMA/PCM,ADPCM
WAV/MID/MOD player.
Code name: Brick
In this video some MOD trackers are played.
MOD trackers are actualy not decoded by the
VS1003, their decoded by the main MCU
ATmega32 @ 16MHz and sound stream is going
into VS1003 like PCM WAV 19700Hz 16-bit
stereo with infinite length.
Some detailed information about my MOD
decoder with ATmega32 can be foung here:

Note 1: sound was recorded separately via
"line in" input on my PC, video via my
digital camera and then combined in
VirtualDub so it's not perfectly
synchronized.
Note 2: I had to add secondary sound card
because integrated one wasn't capable to
record sound without some -30dB level noise
(damned) but new one is for a change not able
to drive headphones directly so I have two
SB's now (damn^2)
Note 3: than I've found out that CoolEdit is
from some reason not able to record 5 minutes
without some buffer underflows (click sound
every 30 second or so (and I've tried that on
several PC's including fast core duo (and
I've tried many settings))), so I wrote my
own rec. SW (damn^3)
