first of all, apologies for bringing back zombie thread.
I too was excited to see the CMSIS DSP library and such. I've download Atollic TrueStudio and thought STM32 was the way to go. All i want is a cheap ARM (maybe Cortex M4) to do audio DSP stuff with.
Was I barking up the wrong tree too?
STM32 seems open, but arduino even more open. Can someone point me in the right direction? I want to do FFT and reverse FFT in real time for audio.
I'm just so overwhelmed and if someone familiar can point me in the right direction it'd make me a happy pepe.
