It's not done because it causes time-domain aliasing. You can think of the
DFT (or FFT) as a sampled version of the continuous frequency DTFT. If the
samples aren't dense enough, you get aliasing in the dual domain (the
time-domain in this case). This aliasing can be perfectly cancelled during

Another consideration is whether the DSP supports real hardware
floating-point vs fixed-point arithmetic.
If you are doing a lot of low level stuff like filters then fixed-point may
be fine. But if you are more comfortable with higher level full range
floating point then you may prefer a DSP that

Most (all?) DSPs will be somewhat optimised for performing FFTs. They
may not have special FFT hardware, but the vendor will most likely
provide an optimised FFT library.

Well, those could be really handy if your guitar pedal does some filter

Hi everyone,
I'm new to this community and I'm looking forward to meeting many like-minded

I have a new project in mind, which will, for the first time, include a DSP
