externals for puredata

these are externals/plugins to be used with Pure Data

• f0_auto_scale - finds min and max values of a stream of numbers and uses them as input scaling range
• f0_beats_to_frames - calculates how many [video]frames will fit in x beats
• f0_construct - a constructive constructor
• f0_distance - calculate the distance between successive (delta) points in 1, 2 or 3 dimensions
• f0_fmod - floating-point modulo operator
• f0_fold - fold float and integer numbers to a specified range
• f0_frames_to_beats - calculates how many beats will fit in x [video]frames
• f0_gcd - find the greatest common divisor
• f0_inc_dec_split - detect direction of incoming values and split to different outlets
• f0_limit_counter - a different counter with floor and ceiling
• f0_noergaard - per nørgård's infinity series
• f0_range - finds minimum, middle and maximum values from a stream of values
• f0_range2 - similar to f0_range but with an added smooth factor
• f0_ratio - keep width/height proportion
• f0_round - round values to nearest quantised value
• f0_slub - generate cpu spikes - disrupt timing version
• f0_slub~ - generate cpu spikes - audio click version
• f0_smooth - single exponential smoothing. good for filtering data from sensors
• f0_smooth2 - double exponential smoothing
• f0_snap - smooth by snapping
• f0_tune - an external that "quantise" frequencies
• f0_wrap - wrap float or integer numbers

download&install binaries

osx: download this zipped archive and extract the folder f0extpd_osx. (the other stuff you can trash). put the f0extpd_osx folder somewhere on your harddrive, open pd and go to preferences/path and add the folder there.

(optional) build from source

open terminal, cd to source folder and type make and then make install.

on mac osx that should build and automatically copy all the externals+helpfiles to your ~/Library/Pd folder.
