[PD] Impulse Response - Convolution Reverb

hi davide

i found two objects for doing convolution:

[partconv~] from ben saylor

[FIR~] from iemlib

partconv means partitioned convolution. i'm not an expert, but afaik
this means it makes a few small convolutions instead of one very big.
this makes [partconv~] less cpu consumptive than [FIR~].

for doing reverb i suggest to use [partconv~], because of the huge
length of the IR.
