A convolution is simply a multiplication in frequency domain:
so you have to fft~ or rfft~ your signal, then make a (complex!)
multiplication and transform it back to time domain (rfft~) ...
You should also use a window (see the fft examples), normalization
(1/blocksize) and maybe a bigger blocksize (with block~) with an overlap
...
