I am looking for an affordable DSP in price to manufacture a small device capable of real-time audio effects processing through a microphone. Is there anybody who can recommend me which DSP could be the most interesting to program and use for this application? I have seen the series 563XX might be the ones, but I am a bit lost in the different models, and maybe I am missing some other. It would also be very interesting if it contains a good built-in ADC/DAC to facilitate the design.
The effects I plan to program in the DSP are the basic array: delays, filters, distortion, modulation, flanger/phaser, pitch shifter, and even a vocoder.
Any suggestions/ideas? Thanks in advance!!!
