Well... I try
Devices and Stuff:
- arduino uno
- shifty vu shield
- 2 servos
- a self-recorded and mixed song -> for the listener
- the raw files of that song -> for the song that controles the servos (L-channel = Voice, R-Channel = Guitar)
should also work for visualizations
- a device that can play 5.1 files (PC with 5.1 sound card or maybe a DVD-Player)
- Audioeditoring programm - > panning voice and guitar to L and R
+ creating 4 mono WAV-Files out of the two songs
+ creating a 5.1 File out of the 4 WAV-Files
I recorded with Logic (shareware)
I used Adobe Soundbooth CS5 (shareware) to create the monofiles. And I used Adobe Premiere Pro CS5 (shareware) to create the 5.1 WAV-File. There I panned the final mix to Front L and R and the controlling mix to Back L and R.
The shifty vu shield is able to receive a stereo signal, get its' volume values and send them to the arduinos analogue pins. These values can be used to control servos, light bars or whatever.
So... what I finally did is:
When I play the song on my VLC player. My Soundcard sends a stereo signal to my Headphones (or HiFi-System). Via speakerslot of the card.
And it sends also a stereo signal ouf speaker-back-slot to the arduino. And so I can control the the servos while listening to the song at the same time.
It's not testet yet. But for being independent of a PC-System I'm going to use a DVD-standalone-player with 5.1 outputs.
I think it should work while using two 2-chinch-to-stereojack cables. One is connected to the arduino, the other one to the sondsystem.
I'm just not sure if I need any amplification between DVD player and arduino/soundsystem. Does anyone know if I will need it? Right now I can't try because I don't have a DVD-player with 5.1 outputs?
