Debian Multimedia Pure data packages

deken is a simple and easy to use package manager for Pure Data (Pd).

This package provides a command line tool that facilitates the creation and upload of your own packages to the official package repository puredata.info.

Gem is a loadable library for Pure Data (Pd), which adds OpenGL graphics rendering and animation to Pd. Pd is a graphical programming language and computer music system.

This package contains the core library. If you want to use external data (live video capture, film footage, still images, ...), you have to install one (or all) of the gem-plugin-* packages.

PDP is an extension library for Pd that allows you to manipulate movies and live video data in realtime. PDP stands for Pd Packet, the data container that is used for images in PDP.

This library extends PDP with texture and render context packets, to use some of the power of current video hardware.

Warning: this is still experimental and incomplete!

[abl_link~] is a Pd object that integrates Ableton Link into Pure Data (Pd). It has four outlets, which emit the index of the current step (at the beginning of each step), the current phase and beat time on each DSP tick, as well as the tempo on tempo changes. Phase and beat time are Link concepts. The purpose of the step feature is to generate events in Pd at a given rate (measured in steps per beat).

libambix is a library of C routines for reading and writing files following the "ambix" (AMBIsonics eXchange) conventions.

Ambisonics is a periphonic (3D) surround sound technique, with a scalable spatial resolution (put simply: "the more audio channels you use, the better"). The ambix convention defines an extensible format for exchanging soundfiles containing Higher Order Ambisonics data.

This package contains a set of Pure Data (Pd) objects to interact with ambix-files:

• [ambix_info]: information about ambix files
• [ambix_read~]: play an ambix file (simple mode)
• [ambix_readX~]: play an ambix file (extended mode)
• [ambix_write~]: record an ambix file

This provides a simple object for Pure Data that reports the size of an array by name. For historical reasons, it is packaged as a standalone object. It is a very simple object, but has always been distributed by itself. It is packaged alone in keeping with the one-library-per-package style of all other pd libraries.

This is a tiny package that might otherwise be lumped into a 'goodies' package, but it is the only tiny one like this, so a 'goodies' package would end up being just this single object anyway.

Since Pd>=0.47, this object can be replaced with the built-in [array size].

aubio gathers a set of functions for audio signal segmentation and labelling. The library contains a phase vocoder, onset and pitch detection functions, a beat tracking algorithm and other sound processing utilities.

This package provides PureData objects to use the aubio features.

AutoPreset is a simple state saving system (like rradical/ssad, among other ones). It aims to be simple and yet powerful.

One particularity of this system is to be able to interpolate float parameters between different settings (parameter morphing).

bassemu~ is an object that simulates a transistor-based electronic synthesizer. This serves as a emulation of an analogue bass synth. It includes the obligatory filter, saw/rect/tri/sine waveform select, an extra hi-pass filter. You can also feed another signal to its left inlet, and filter that, either alone or mixed to the vco.

Also included is a small, messy gop abstraction to resemble a 16-step sequencer.

This object is a realtime scheduler, event-delay, and quantizer object for Pure Data. It is used for making beats and other rhythmic sequences. Any list starting with a number T sent to the left inlet, will be sent to the output after T beats, quantized with tpq (tick per quarter) and stripped of the leading beat number. The tempo can be changed dynamically on the right inlet The quantification can be set at any time with a set-tpq message.

Boids is a bird flight and animal flock simulator. It is based on the same algorithm which was used in Jurassic Park for the herding dinosaurs. Boids takes an integer argument which is the number of boids. Each time Boids receives a bang, it calculates and outputs the new positions of the boids. The output consists of thew coordiantes for each boid, the number and type depending on the mode.

The flight parameters can be changed with messages. Use the 'dump' message to output a list of the current parameter settings.

For more information about the Boids algorithm, see Craig Reynolds' Web site at http://www.red3d.com/cwr/

bsaylor is a library of Pure Data objects by Benjamin Saylor:

pvoc~: a phase vocoder based on Pd's 09.pvoc.pd example patch. Advantages over the abstraction include (reportedly) faster execution, instantaneous response to input, and adjustable phase locking. It requires FFTW3.

susloop~: sample player with various loop methods (ping-pong, ... ) like a classic tracker interface.

svf~: a signal-controlled port of Steve Harris' state variable filter LADSPA plugin (http://plugin.org.uk).

zhzhx~: Turns the input signal into a staticky, distorted mess. Comes with tone control

chaos is a library of Pd objects for calculating various chaotic attractors, including: lorenz, rossler, henon, ikeda, attract1, base, base3, dejong, gingerbreadman, hopalong, latoocarfian, latoomutalpha, latoomutbeta, latoomutgamma, logistic, lotka_volterra, martin, mlogistic, pickover, popcorn, quadruptwo, standardmap, strange1, tent, three_d, threeply, tinkerbell and unity.

The package includes 1, 2 and 3 dimensional attractors. There are outlets for each dimension, starting from the left, followed by three outlets for attractor data (see the help patches for details). The scale of the values vary between the different attractors.

Some of the algorithms were derived from other projects, including Julian C. Sprott's attract.java and algorithms by Cliff Pickover.

This is a collection of small objects that emulate logic CMOS components, namely the CD4000 series. It currently contains 25 objects of the cd4000 series.

The emulation assumes idealized components, and works in the message domain.

• cx.mean, cx.avgdev, cx.stddev: calculate mean, standard and average deviation of a signal in an array

Cyclone is a library of PureData classes, bringing some level of compatibility between Max/MSP and Pd environments.

In its current form, cyclone is mainly for people using both Max and Pd, and thus wanting to develop cross-platform patches. In this respect, cyclone has much in common with Thomas Grill's flext, and flext-based externals. While flext enables developing new cross-platform classes, cyclone makes existing classes cross-platform.

Cyclone also comes handy, somewhat, in the task of importing Max/MSP patches into Pd. Do not expect miracles, though, it is usually not an easy task.

deken is a simple and easy to use package manager for Pure Data (Pd).

The deken-plugin integrates with the Pd user interface, where you can search for externals and install them with a single click. Since Pd-0.47, the deken-plugin is integrated into Pure Data (but the Debian package provides an updated plugin)

Available backends that provide packages are:

• puredata.info (downloads packages via the Pure Data community website and installs them into the per-user installation directory (~/pd-externals))
• apt (installs Pd packages the Debian way; packaged as "pd-deken-apt")

deken is a simple and easy to use package manager for Pure Data (Pd).

The deken-plugin integrates with the Pd user interface, where you can search for externals and install them with a single click.

This addon allows one to additionally use 'apt' for installing Debian provided packages from within the deken-plugin (rather than downloading binaries from the Pure Data community website).

earplug~ is a realtime binaural filter based on KEMAR impulse measurement. It allows you to spatialize a sound in realtime. It basically takes the KEMAR data set, and interpolates 366 locations where HRTF measurement exists in a spherical surface. you get azimuth control 0-360 and elevation -40 - 90.

This library is a collection of objects for analyzing audio to get musical information, like spectrum and peak information, to generate sound based on analysis, like Linear-Predictive Coding, and for working with polyphony.

Extended View Toolkit is a set of Pure Data (Pd) abstractions for combining multiple video or image sources into a panoramic image and for projection setups with multiple projectors or projection environments with challenging geometric forms, better known as video mapping.

Multiple input media (e.g. camera input, video files, image files, 3D renderings) can be processed. It is possible to create imagery or video by either stitching multiple inputs to one continuous, or by unwrapping a 360-degree image taken with a special optical lens system. Such processed media input can then be projected onto even irregular shaped surfaces. It is possible to blend smoothly between multiple projectors, to create seamless immersive media environments.

FFTease 2.5 objects will reconfigure themselves in response to changes in FFT size or signal vector size. Therefore, they may now be used in MaxMSP poly~ objects with downsampling or upsampling. Changes in vector size remain subject to limitations imposed by the current poly~ (and Pluggo) architecture.

Caveat: these objects are CPU intensive. A few of these objects in a patch could push your computer to its limits. Be very careful with playback volume as some of the objects produce dramatically different (lower or higher) overall levels.

Flext is a C++ layer for programming externals for Pure Data (Pd) as well as for the proprietary Max/MSP. It provides an object oriented abstraction layer to writing Pd objects.

This package provides the files necessary to compile a Pd external using Flext.

The flite external contains a single Pd class which provides a high-level text-to-speech interface for English based on the 'libflite' library by Alan W Black and Kevin A. Lenzo.

Freeverb is a simple implementation of the standard Schroeder/Moorer reverb model. It uses 8 comb filters on both the left and right channels. Note that this version of Freeverb doesn't contain predelay, or any EQ. It is implemented as a Pd object, so it can easily be inserted into a Pd patch.

ggee is a library for Pure Data by Guenter Geiger with five sections: control, experimental, filters, gui, and signal.

The 'hcs' library is a random grabbag of objects that are experiments that sometimes lead to full-fledged libraries. There are objects for getting UNIX file and permissions information (group, gid2group_name, group_name2gid, uid2username, username2uid, hostname, stat, uname, setenv), Pd GUI manipulation (canvas_name, window_name, sys_gui, tcl_version, ce_path, tkconsole, pointer_position, cursor), handling filenames (file_type, folder_list, helppath, split_path), and more.

The default external objects loader of Pure Data (Pd) maps object names to filenames and C-function names. Unfortunately both filenames and C-function names have restrictions (like the impossibility to include a '/').

This library adds an escaping mechanism based on hexadecimal encoding that allows one to write and use objects that would otherwise be impossible.

[hid] is a Pure Data object for reading data from USB HID devices like keyboards, mice, joysticks, gamepads, keypads, and all sorts of other esoteric controllers like USB knobs, touchscreens, Apple IR Remotes, etc. It represents the data with a cross-platform message scheme which is then translated to the underlying native API for input devices (Linux input.h or Mac OS X HID Utilities).

Pure Data (also known as Pd) is a real-time graphical programming environment for audio and graphics processing.

This package installs all packages necessary for the "iem" flavour, a Pd-vanilla based distribution.

This library contains 3 objects, for calculating Ambisonics encoder matrices, rotation matrices and decoder matrices from 1st to 4th order in 3D, or from 1st to 12th order in 2D.

This library contains a collection of very low-level objects for Pd, that are usually used to build higher-level abstractions for dynamic patching and live coding by adding reflection capabilities to the patcher language.

• [tcpserver], [tcpclient]: bidirectional communication over TCP/IP
• [udpreceive], [udpsend]: unidirectional communication over UDP

The included state engine allows complex scene management as well as fully programmable scene transitions.

The 'libdir' loader is a Pure Data loader which supports the libdir library format. The libdir library format aims to be a common library format for Pd which works with objects written in any language, including Pd. This library format was designed to be easy to create, install, and use. It should work when installed into the global path (i.e. pd/extra) or when copied locally into a project folder. It should work with objects written in any supported language (i.e. binaries, .pd, and the various loaders like pdlua and tclpd).

list-abs is a Pd library of all sorts of operations for lists of data, ranging from mathematics, sorting, ranging, etc. All of the objects are implemented using Pd, and for the most part only using objects included in Pd-vanilla.

This library adds objects to Pure Data (Pd) that allow one to create printout at various verbosity levels.

The objects can be used as drop-in replacement for the standard [print] object, but the printed messages can be filtered and have a colourful appearance.

pd-lua adds a new loader to Pure Data (Pd), that allows one to load objectclasses written in the popular Lua programming language.

Some programming problems are complicated to express in graphical dataflow languages like Pd, requiring the user to ressort to objectclasses written in more general purpose languages. For those who do not want to use compiled languages like C/C++, this package offers the possibility to write first-class objectclasses in the lightweight programming language "Lua".

Markex is an external library of miscellaneous objects that was begun in 1994 and originally included in GEM. It is largely here for the sake of old projects that might still rely on it. The included functionality has been improved in other libraries.

maxlib is a library of non-tilde externals for Pd. The objects can be very useful to analyse any musical performance. Some of the objects are 'borrowed' from Max (they are not ported but rewritten for Pd cheap immitations). maxlib has been extended by objects of more general use and some which can be use for composition purposes. It also includes some networking objects for writing Pd patches that act as network clients and servers.

This library adds a programmatic interface to Pd (Pure Data) to query the currently available audio and MIDI backends (like alsa, jack, ...) and interfaces (like built-in soundcard, virtual devices, ...), and allows one to enable and configure them from within a Pd patch.

• about - delivers a number that is "about" the same as the input number

Moonlib includes three sub-sections: nilib, which is a kind of wrapper between Pd and Gtk, sublib, which is a collection of gui control objects, and other, which are miscellaneous objects:

• tabenv: like env~, an enveloppe follower, but computing on a table, so possibly much speeder than real-time env~'s computation
• tabsort, tabsort2: returns the indices of the sorted table, tabsort2 is bidimensional
• gamme: one octave of a piano keyboard used to filter/choose notes in a selected scale

This library adds Pure Data (Pd) objects that allow one to build a networking infrastructure within Pd on OSI-Layer 4 (transport layer). The objects use threads to allow for non-blocking network communication within an audio realtime environment.

• [tcpreceive], [tcpsend]: unidirectional communication over TCP/IP
• [tcpserver], [tcpclient]: bidirectional communication over TCP/IP
• [udpreceive], [udpsend]: unidirectional communication over UDP
• [udpsndrcv]: bidirectional communication over UDP
• [udpsend~], [udpreceive~]: transmit uncompressed signals via UDP Since these objects only send/receive lists of bytes, you will most likely need to add some glue to implement higher-level protocols (and transmit meaningful data).

The nusmuk library contains object targeted at high-quality audio synthesis like band-limited synthesizers, audio filters and effects and interpolating table lookups. It also includes a number of general purpose utilities, ranging from simple shorthand abstractions to higher mathematics (random generators).

This library allows one to construct and parse OSC messages within Pd. It includes support for ordinary OSC-messages, typetags, timetags and bundles.

These objects are transport-agnostic, so you can use them to transmit OSC over UDP, TCP/IP, serial port, or in fact whatever you want. However, you will have to install additional libraries that will handle the transport layer (like pd-net or pd-comport).

Note however, that OSC is a packet-based protocol, so if you intend to use it with a stream-based transport (like TCP/IP or the serial line), you must use a packetizer (the OSC-specifications suggest to use SLIP, as provided by pd-slip).

A library of stereo panning algorithms from various sources, including equal power panning and linear panning.

This software library offers the possibility to experiment with a number of compositional techniques, such as serial procedures, permutations and controlled randomness.

Most of these objects are geared towards straightforward processing of data. By using these specialized objects together in a patch, programming becomes much more clear and easy.

Many functions that are often useful in algorithmic composition are provided with this library - therefore the composer could concentrate rather on the composition than the programming aspects.

This a library for Pure Data that provides objects for realtime Vector Base Amplitude Panning. Vector Base Amplitude Panning (VBAP) is a method for positioning virtual sources to arbitrary directions using a setup of multiple loudspeakers. In VBAP the number of loudspeakers can be arbitrary, and they can be positioned in an arbitrary 2-D or 3-D setups. VBAP produces virtual sources that are as sharp as is possible with current loudspeaker configuration and amplitude panning methods, since it uses at one time the minimum number of loudspeakers needed, one, two, or three.

With 2-D setups VBAP is a reformulation of the existing pair-wise panning method. Different from other panning algorithms, VBAP can be generalized for 3-D loudspeaker setups as a triplet-wise panning method. A sound signal is then applied to one, two, or three loudspeakers simultaneously. VBAP has certain advantages compared to earlier virtual source positioning methods in arbitrary layouts. Previous methods either used all loudspeakers to produce virtual sources, which results in some artefacts, or they used loudspeaker triplets with a non-generalizable 2-D user interface.

The directional qualities of virtual sources generated with VBAP can be stated as follows. Directional coordinates used for this purpose are the angle between a position vector and the median plane (θcc), and the angle between a projection of a position vector to the median plane and frontal direction (Φcc). The perceived θcc direction of a virtual source coincides well with the VBAP panning direction when a loudspeaker set is near the median plane. When the loudspeaker set is moved towards a side of a listener, the perceived θcc direction is biased towards the median plane. The perceived Φcc direction of an amplitude-panned virtual source is individual and cannot be predicted with any panning law.
