arguments: 0 - init range
attributes: none
messages: range - set unwrap range
inlets: 0 - messages only
outlets: 0 - undefined
gbr.wind= apply a window to an incoming frame, grain or wave
Applies a chosen (and parametrized) window to the incomming fmat (column by column).The user can chose among various window types (see help patch).
arguments: <sym: function> [<any: parameters> ...] - init window function and parameters
attributes: none
messages: set <sym: function> [<any: parameters> ...] - set window function and parameters
inlets: 0 <fmat|fvec: vector> - input vector to be windowed
1 [<any: parameters> ...] - set window parameters
outlets: 0 <fmat|fvec: vector> - output incoming vector with applied window
