buffir~ External buffir~ is a buffer~ based fir(finite impulse response) filter.
buffir~ is a buffer~ based fir(finite impulse response) filter. an input signal is convolved with n samples of a buffer. Currently the maximum number of points is 128.
convolve~ External convolve~ is a buffer~ based FIR (finite impulse response) convolution filter. An input signal is convolved with the samples of the buffer. An amplitude treshold can be set for saving processing time. The FIR length is free.
The functionality is similar to the "buffir~" object: a buffer~ is used to hold the FIR that will convolve the signal coming in the first inlet. But convolve~ scans the buffer~ for data above a given amplitude treshold so that the callculation process can be reduced (instead of high dynamic precision.) This faster calculation has as a consequence that the offset and legth of the FIR aren't signal inlets like in buffir~.
