Detailed Description

the simpliest form of an STFT

you can build this easier by concat an TDSPChop-TDSPfft-TDSPChop, which is good for BlockLen which are greater than the signal len For lower len TDSPBlockfft will be much faster due to large object communication overhead in the Chop/fft/Chop-case
