I want to develop a system, using an Arduino controller board.
However, I need the controller to respond also to the FFT of ambient
sounds.
So the system will have to include also a microphone and a DSP.
My requirements and budget are hobbyist level, so what is the
recommendation for a DSP or FFT processor which meets as many as
feasible of the following requirements:
1. Low unit price
2. Availability of a cheap development board
3. Availability of Free (or at least zero cost) development toolchain
4. Can be purchased off the shelf in a shop in Har Zion St., Tel Aviv.
Thanks,
--- Omer
