Inertia Abstraction iterative smoother smooth entering flow of numbers only when values happen
int External Store an integer
Int takes an optional argument which can be changed via an int in the right inlet without producing output. The left inlet takes an int which changes the value, or 'bang'. Both messages produce output. The outlet sends the value as an integer.
integ Abstraction Accumulates input values until a bang (or any input) is sent to the right inlet.
jb.delta Abstraction calculate difference between successive values
jb.float Abstraction store and interally operate upon a floating-point value
jb.median Abstraction return the median value of a numerical list
jcom.limiter~ External Look-ahead limiter with built-in DC blocking and Overdrive
This object was initially an off-shoot from jhno's limi~ object for MaxMSP. This variant supports attributes, gain-related values specified in decibels, and a built in DC Blocker.
jcom.round External Round-off to int value. Work with positive and negative numbers.
jg.spectdelay~ External spectral delay
jg.spectdelay~ performs an FFT of the input and supplies each frequency band with a volume control (EQ) and a recirculating delay line. EQ gain, delay time, and delay feedback can be controlled in real time. There is a way to apply a value change to a contiguous group of frequency bands. So, for example, you can hook up 16 sliders and control the bands in a way that provides more resolution to lower frequencies than if you merely divided the spectrum into 16 equal parts.

GPL-licensed source code is available.
jit.3m External Report min/mean/max values
The jit.3m object reports the minimum, mean, and maximum values for each plane of a given input matrix as lists of sizeplanecount, one value for each plane. The list of minimum values are sent out the left outlet of the object, the list of mean values are sent out the middle outlet, and the list of maximum values is sent out the right outlet.
jit.alphablend External Use the alpha channel of one image to blend two images together
The jit.alphablend object uses alpha channel (plane 0) of the input matrix in the left inlet as a per-cell crossfade value, and crossfades between the input matrices in the left and right inlets. In mode 0, a low value means more of the right input matrix, while a high value means more of the left input matrix. In mode 1, a low value means more of the left input matrix, while a high value means more of the right input matrix.
jit.altern External Color screen with threshold
The jit.altern object overlays a color screen onto incoming matrices. The original matrix values are revealed through "gaps" in the screen.
jit.avg4 External Average four points
The jit.avg4 object replaces the values in each cell of an incoming matrix with average values derived from four cells at a specified distance from the original.
jit.charmap External 256 point input to output map
he jit.charmap object uses its right input matrix as a 256-point input to output map. Input values are replaced by the corresponding output value.
jit.chromakey External Keying based on chromatic distance
The jit.chromakey object measures the chromatic distance of each of the left input's cells(pixels) with a reference color (a.k.a "green screening"). The total chromatic distance is calculated by summing the absolute value of each color channel's distance from the reference color's corresponding color channel.

When manipulating human knowledge such as perception, feelings, appreciation, veracity of facts, etc., the classical logic that recognize only two truth degrees (true or false) is not always the most suitable.

To solve this problem, more than two degrees are considered in the non-classical logics. The fuzzy logic is one of these logics.

In this logic, facts are represented through membership functions: when the membership value is equal to 1 the fact is exactly true; when it is equal to 0 the fact is exactly false; in between there is an uncertainty about the veracity of the fact.

These membership functions are called "fuzzy subsets". They can be of different shapes: gaussian, trapezoidal, triangular, etc.

Thus the aim of the fuzzy logic is to propose a theoretical framework for the manipulation - representation and reasoning - of such facts.

The Fuzzy Lib library implements all the tools that are necessary to handle this manipulation: representation of a fuzzy subset (among them are the fuzzification, defuzzification and partitioning), reasoning process (generalized modus ponens, fuzzy implications, t-norms, t-conorms, etc.).

This version 1 of the Fuzzy Lib enables to implement fuzzification, uncertain reasoning and defuzzification for any number of data in the framework of Max/MSP environment.
Litter Power Pro Package
debug: SELECT prenom, nom FROM auteurs RIGHT JOIN auteur_libraries USING (id_auteur) WHERE auteur_libraries.id_library='54'Peter Castine The Litter Power package consists of over 60 external objects, including a number of new MSP noise sources, externals that produce values from a wide variety of random number distributions, and externals for mutation and cross-synthesis.
p.jit.gl.tools
debug: SELECT prenom, nom FROM auteurs RIGHT JOIN auteur_libraries USING (id_auteur) WHERE auteur_libraries.id_library='123' Pelado the p.jit.gl tools are designed to provide for easier learning of and experimenting with the many attributes that are available to jitter's gl objects by making them a whole lot more transparent and accessible. patches expose jitter gl object's attributes to interfaces that allow you to immediately edit and change an attribute's value. many of the parameters are attached to blines, which provide smooth changes while rendering, and all settings can be saved and recalled as presets using the pattrs that are embedded in the patches.
Panaiotis Objects
debug: SELECT prenom, nom FROM auteurs RIGHT JOIN auteur_libraries USING (id_auteur) WHERE auteur_libraries.id_library='122' Panaiotis The Mac version is UB.

These Max objects have been enhanced since the documentation to the left was written. Help files for the objects provide information on enhancements.

The matrix object has been substantially upgraded. It now combines features of unpack, spray, funnel, append, and prepend into one object. This makes a great object to place between controllers and jit objects because it acts like a multi-prepend. There are new configuration commands and enhancements to the old: even, odd, mod,and range, among others). Most commands can be applied to inlets of outlets. There is also a mute function that adds another layer of control. Matrixctrl support has been enhanced. See the help file for full details and examples.

Most other objects now fully support floats. RCer and autocount will count in float values, not just integers.

Notegen16 is a 16 channel version of its predecessor: notegen. It is more generalized and much more efficient.

suivi
debug: SELECT prenom, nom FROM auteurs RIGHT JOIN auteur_libraries USING (id_auteur) WHERE auteur_libraries.id_library='88' Ircam Two externals performing score following on soloist performances using Hidden Markov Models (HMM)
Suivi is based on FTM and requires the shared library FTMlib for Max/MSP. Both externals use an FTM track object - a sequence of time-tagged FTM values - to store the score of the soloist performance to be followed. Notes, trills and other elements of the score are represented by FTM score objects (FTM scoob class). For the moment, scores can be imported from standard MIDI files only.
An editor for the FTM track class, which will also provide a graphical control interface for the score follower is under development as well as the import of MusicXML files.
The suivi object set is distributed within the IRCAM Forum.
