I want to built a simple audio around one object (maybe several objects) in exhibition. I looked audio sound kit, but now it is not available anymore.
So, now I have to buy items separately to combine at my home. I was looking SparkFun wav or mp3 trigger and for more complex 8 channell Tsunami Super wav trigger board. Talking about powering I like an idea to have power from USB power banks in the case for moving objects to place without electricity and in case to have electricity still powering from USB but from USB wall adapters. I would use a simple hamburger loudspeaker or/and transducers (was looking to large and small)
My needs for 2 different purposes.
1.
A) Playing 1 wav or mp3 file from SD card to hamburger loudspeaker or transducer
B) choose different files (up to 8) from SD card to hamburger loudspeaker or transducer
2.
A) Playing 1 multichannel wav file (8 channels) or up to 8 mono files in sync from SD card to hamburger or other powered loudspeakers or transducer
B) choose different multichannel files (up to 8) from or up to 8 mono files in one project in sync from SD card to hamburger or other powered loudspeakers or transducer
Does transducer need a separate amplifier?
I want to build everything at once, so my question is which items i need to order. This is a first time to do things like this. Second time i will be more skilled and probably i need no such advice. But now, … it is so necessary.
