zexyzexy provides several addon objects for the Pd computer music system, including (but not limited to) objects for message handling (construction, parsing, control flow), signal handling (synthesis, analysis, comparison) et al.
elseELSE is a big library of externals that extends the performance of Pd.
flucoma The Fluid Corpus Manipulation project (FluCoMa) instigates new musical ways of exploiting ever-growing banks of sounds and gestures within the digital composition process, by bringing breakthroughs in signal decomposition, DSP, and machine learning to the toolset of techno-fluent computer composers, creative coders, and digital artists..
cycloneCyclone is a library for Pure Data (Pd) that provides objects mimicking those in Max/MSP.
pmpdpmpd is a collection of objects for Pd (Pure Data), enabling real-time simulations of physical phenomena.
timbreIDLibtimbreIDLib is a library of audio analysis externals for Pure Data.
ffteaseFFTease is a collection of objects designed to facilitate spectral sound processing in Max and Pd.
piropiro is Pd-port of irmeasure~ and multiconvolve~ from the HISSTools Impulse Response Toolbox (HIRT) · Stands for Pd Impulse Response Objects, or "fire" (ancient Greek), or sounds like "Pirro" (Pyrrhus) – since this port took a very long period!.
neimogpd-neimog is a collection of objects, tools, and integrations for Pure Data (Pd) that I use in my work.
