DSP selection

I am designing a monitoring system in which the sound of an industrial motor should be analyzed to tell the condition of the motor. For this application I need to use FFT. So I chose DSP as the capable processor. Now I need help in selecting a cost effective DSP. Any kind of help would be appreciated.


My questions;

1. How do I decide how many points will be needed for FFT?

2. Floating point or fixed point?

3. Number of bits?

4. I need to serve 10 channels

5. ADC/DAC separately or embedded in DSP? which would be a cost effective choice?


Thanks for your time.
