I don't know if I'm posting this in the right place, if not, please forgive me.
Can anyone give me some advice on any *cheap* (less than $100) development board with a nice microcontroller with onboard ADC, DAC, and capable of doing a Fast Fourier Transform (16 or 32 bits architecture)?
I would like to make some experiments with digital signal processing. Specifically, with audio signals in realtime...
Am I asking too much? :)
Thank you in advance.
