Here in India , we have gadgets called "shruthi boxes" which produce a continuous drone which is used for tuning various instruments or for aid while singing.
The problem is that these things are hideously expensive for the simple things that they are (a basic one is 120$ , and a good one will be 200$).
So ,i was thinking of making one myself using a AVR uC.
Here is the link to an online sruthi box :
Royal Carpet: karnATik Online Shruti Box
The sound that comes out of is very simple and is in a continuous loop.
So , is there any way of loading a part of the sound into the uC and then looping it as to produce a continuous sound?
It would be pretty much a revolution in india if someone manages to make sumthing like this and sell it for less than 10$...
