Density
 Standalone Application 

Density Granular Synthesis Environment Density is a new realtime software designed especially for LIVE asynchronous granular synthesis and sound file granulation, a genuine granular playground able to generate a wide range of usual and not so usual effects: time/pitch shifting, time/pitch jittering, intricate textures, grain fountain/pulverizer, recording and manipulation of buffers, complex scrub pad exploration, dynamic envelope shape drawing and many more. Besides the basic tools, even more advanced tools are available to control the grains! You have smooth transitions (interpolation) between global presets (snapshots), you can navigate with hyperVectorial pads or/and sequence your snaps using the "snap rhythm improviser" which provides an unique & powerful way to generate incredible sound phrases. Like any good liveoriented tool, all widgets are controllable via MIDI and OSC protocol, easy to map and manipulate with your MIDI controller. All is packed in an optimized visually sharp interface, easy to use and access when fast improvising live or lazy composing in a studio.

Libraries  
Optimized gates

Stephen Kay 
7 different optimized gates ("bgate" for bangs, "igate" for ints, "fgate" for floats, "sgate" for symbols, and "lgate" for lists. These do not need to do a message lookup, since they only deal with one data type. Also includes "andgate" and "orgate" by David Roach) 
SFA Max/MSP Library

Stefano Fasciani 
The SFAMaxLib is a collection of Max/MSP objects developed in the context of the VCI4DMI. It includes functions and utilities in the form of FTM externals, FTM abstractions and Max abstractions. FTM is a shared library for Max/MSP developed by IRCAM, which provides a small and simple realtime object system and a set of optimized services to be used within Max/MSP externals.
List of FTM Externals: sfa.eig  eigenvalues; sfa.inputcombinations  combination generator; sfa.levinson  levinsondurbin recursion; sfa.lpc2cep  lpc to cepstra conversion; sfa.rastafilt  rasta filter; sfa.rmd  relative mean difference; sfa.roots  polynomial roots;
List of Abstractions: sfa.bark.maxpat  energy of the Bark bands from time domain frame;sfa.bark2hz_vect.maxpat  Herts to Bark conversion;sfa.barkspect.maxpat  energy of the Bark bands from spectrum; sfa.ceil.maxpat  ceil function; sfa.featfluxgate.maxpat  gated distance on stream of feature vectors; sfa.fft2barkmx.maxpat  utility subabstraction of sfa.bark; sfa.fft2barkmxN.maxpat  utility subabstraction of sfa.barkspect; sfa.hynek_eq_coeff.maxpat  hynek equalization coefficients; sfa.hz2bark.maxpat  Hertz to Bark conversion; sfa.hz2bark_vect.maxpat  Hertz to Bark conversion for vectors; sfa.hz2mel.maxpat  Hertz to Mel conversion; sfa.idft_real_coeff.maxpat  utility subabstraction of sfa.rastaplp; sfa.maxminmem.maxpat  minimum and maximum of a stream of data; sfa.mfcc.maxpat  MFCC coefficients; sfa.modalphafilter.maxpat  1st order IIR lowpass on a stream of vectors; sfa.nonlinfeqscale.maxpat  linear spectrum to Bark or Mel scale conversion; sfa.rastaplp.maxpat  PLP and RASTAPLP coefficients; sfa.spectmoments.maxpat  4 spectral moments (centroid, deviation, skewness, kurtosis); sfa.3spectmoments+flatness.maxpat  3 spectral moments (centroid, deviation, skewness) and the spectral flatness; sfa.spectralflux.maxpat  spectral flux on stream of spectrum vectors; sfa.spectralfluxgate.maxpat  gated spectral flux on stream of spectrum vectors; sfa.std.maxpat  standard deviation; sfa.win_to_fft_size.maxpat  smaller FFT size given frame size; sfa.GCemulator.maxpat – 3D gestural controller emulator;
