Very cheap digital FX development enviroment (Blue pill)

I think you can, it is just not efficient: https://faust.grame.fr/doc/libraries/#fast-fourier-transform-fft-and-its-inverse-ifft

I was hoping I could do FFT /IFFT in realtime, to implement frequency domain transformations like phase vocoding. I don't think this can be done in faust, from what I see. I have done it in PD, so I was assuming faust could handle it... probably wrong. I will have to play with it when I have my ESP32 board

Is there an approachable way to do phase vocoding in a small embedded form?  I would love to implement a delay with rate shifted repeats or something else fun like that.

Have you looked at the Teensy 4 yet? Using the FFT acceleration in the Keil library you should be able to do decent real time vocoding. You're not going to find anything more powerful than Teensy unless you go for something with full blown Cortex-A processors like a Pi 4 or difficult to program DSPs like Sharc.

I've ordered an ESP32 audio board from Elecrow however what with the virus situation I have no idea when it's going to show up.

Just got an e-mail from Elecrow saying the board shipped and I should get it in 7 to 25 days.  For a moment I was tempted by the "MOD Dwarf" Kickstarter, but there are enough gaps in the details of that where I didn't really feel comfortable going in on it.
