| Zoom H2, Marantz PMD 620, Sony PCM D50: Inside Vs. Out |
 |
For rounds two and three of the Field Recorder
Shootout, Owen O'Malley tests out our three
recorders in a large indoor shopping mall and at
the train tracks! We will still be taking bets,
however. On anything. Owen also explains why we
didn't put a windscreen on any of these recorders,
and it's not because we're totally ignorant, we
promise. See more on gearwire.com.

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)
