Before buying

Hi,

I need to do an FFT and reverse fft on a stereo signal

  • what is the audio quality in term of noise of the Daisy IN/OUT?
  • is it powerful enough, to do complex effects on the spectrum level ?

thanks

Hi phil,
About audio quality, I can tell you that’s it is really good.
I can’t give you real SNR value, but I use plenty of daisies on stage for synth, fx and guitar pedals and it is even sometimes quieter than certain pro hardware stuff.

About fft, with a big buffer size, it should be ok.
It is always better to use acceleration framework to speed up things, there’s a subject here but I don’t know if someone achieve to make it work : CMSIS DSP library support (arm_math.h) - #6 by malloyca

thx mate

I’ll order one
