There are plenty of microcontroller families with low cost of entry - AVR/Arduino, MSP430, PIC etc - but what is there in the DSP world?
I was recently fitted with behind-the-ear hearing aids to correct for loss of sensitivity in the kHz range, but I can't get the benefit of them when using headphones. I would therefore like to build a headphone amplifier giving the same correction as my hearing aids and it seems to me that DSP might be a good way to go. (This must be what my hearing aids contain.) Specifically, I need a DSP family capable of implementing a stereo digital filter with a customisable response up to 10kHz, and with a free IDE and programmable with a PicKit 2, BusPirate or AVR as ISP. Is there such a thing? Preferably with not too steep a learning curve?
