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 as PCM WAV 19700Hz 16-bit stereo with infinite length. Some detailed information about my MOD decoder with ATmega32 can be foung here: http://www.elektronika.kvalitne.cz/AT...
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)
All played songs are available at: www.elektronika.kvalitne.cz/garbage/yt/mods.zip
