space~ - object for spatialization of audio sources
by Shahrokh Yadegari 30 Nov '04

30 Nov '04

Hi All, I have just put up an alpha version of space~, which is a real-time implementation of the cmusic's space unit generator with many improvements. I have recently added a considerable amount of code for room management. So use it carefully. You can download compiled versions for Linux and Mac OS X (Darwin) at: http://www.crca.ucsd.edu/~yadegari/space.html I have not compiled it for windows yet. enjoy, Shahrokh. -------------- Notes for version 0.4alpha -------------------------- Lots of code has been added to this version recently for room management and treatment of the reflections when the source is outside of the virtual space. Generally you should not allow the source to go outside of the virtual source. While I have tried to accomodate for the source to be outside of the virtual space and thus have the sense of a source being far apart, you should not depend on this effect to stay the same. As usual reports of bugs and suggestions are welcome. Send me mail at (sdy(a)ucsd.edu). space~ - A module for spatialization of audio sources ----------------------------------------------------- Based on an algorithm and a partial implementaion by F. Richard Moore in "cmusic" as part of the Computer Audio Research Laboratory (CARL) package. Real-time implementation, port to Pd, and new improvements by Shahrokh Yadegari. With the help of Ted Apel , Anthony Burr , Harry Castle, and Miller Puckette. Space~ is a real-time implementation of a general model for spatialization of audio sources. The central conceit of the algorithm is that of a room within a room. The inner room is the space delimited by the speakers which contains the listeners. The model simulates the behavior of the sound source within a user-defined virtual outer room, as heard from the inner room. The speakers act as "windows" throug which sound from the outer room passes. NOTE: In this implementation both the inner and outer rooms are assumed to be squares. Also keep in mind that the simulation of a source in the listening room is not as good as when the source is in the virtual space and currently one hears sudden changes to the level of audio on opposite speakers when a sources passes through an inner wall. The syntax to space~ is a follows: ---------------------------------- space~ [card] [stereo|quad] [inner-room-size outer-room-size] - card - indicates that the cardiod pattern information is supplied for the audio source - stereo|quad - specifies the diffusion mode (quad is the default) - inner room size - is the size of the inner room in meters - outer room size - is the size of the outer room in meters (When inner room size and outer room size are not specified, sizes 4 and 50 meters are assumed.) All inlets and outlets of space~ are of type signal Outputs for stereo ------------------ 1 - Front Left 2 - Front Right 3 - to be connected to Reverb Outputs for quad ---------------- 1 - Front Left 2 - Front Right 3 - Rear Left 4 - Rear Right 5 - to be connected to Reverb Inputs -------- 1 - audio source 2 - X coordinate in meters 3 - Y coordinate in meters 4 - amplitude (not in db) Additional inputs when "card" is specified ------------------------------------------ 5 - Theta (in radians) - source radiation direction 6 - Back - radiation level in the opposite direction (0 <= Back <= 1) Methods ------- stop - stop spatial processing (for saving cpu cycles start - start processing theta - source radiation direction (when "card" is not specified) back - radiation level in the opposite direction of theta (when "card" is not specified) direct - affecting the power laws for calculating the direct ray attenuation reflect - affecting the power laws for calculating the reflected ray attenuation TH (also "th" or "threshold") - threshold value for ray diffraction simulation CF (also "cf" or "crsossfade") - crossfade form for ray diffraction simulation

[ANN] Linux Audio DVD in Keyboards (incl. Pd)
by Frank Barknecht 29 Nov '04

29 Nov '04

Hi, see below for a pre-annoucement regarding a SuSE-Linux-Live-CD in the magazine "Keyboards", available on Dec 3. I helped Matthias a bit to get Pd and a lot of Pd externals working as well, including a complete and working RRADical Pd collection, but unfortunatly excluding Gem and pdp so far. (Accelarated 3D is a bit 'difficult' to get right on Live-CDs which must not ship proprietary drivers...) Ciao -- Frank ----- Forwarded message from Matthias Nagorni <mana(a)suse.de> ----- Date: Mon, 29 Nov 2004 17:01:26 +0100 (CET) From: Matthias Nagorni <mana(a)suse.de> To: A list for linux audio users <linux-audio-user(a)music.columbia.edu> Subject: [linux-audio-user] [ANN] Linux Audio DVD in Keyboards Hi, have a look at www.keyboards.de and click on the Tux ;-) German Keyboards has published a bootable DVD that launches a Linux Audio Live CD featuring the complete series of audio apps that ship with SUSE 9.2 (including PD and SuperCollider). A HTML-document provides information and many links to demo scripts that start combinations of audio apps, including synths (ams, AEOLUS, ZynAddSubFX, PD, SuperCollider), Hydrogen, NoteEdit and JAAA. A complete sample recording session wired up with JACK and sent through JAMin is also provided as script. The DVD also includes Ardour, MusE and many other programs. BTW This DVD is also a video-DVD, suitable for playback in standalone DVD players. And it's the 20th anniversary edition of Keyboards. The magazine will ship on friday, 3. december.

PD-list change of policy for unsubscribed posters
by Johannes M Zmoelnig 29 Nov '04

29 Nov '04

hi. the current policy regarding posts to the pd-lists (pd-list, pd-announce, pd-ot, pd-dev) from non-subscribed posters is as follows: SPAM is silently dropped (the sender is not notified that the mail did not make it to the list) other mails (e.g. mails from people that are interested in pd but do not want to subscribe, or mails from subscribed people that are sent from "unknown" (e.g. not-subscribed) addresses) are rejected (this is: the sender gets an email saying that his email did not make it to the list because...) unfortunately this is a constant annoyance for the list-administrator (the poor person has to go through ~100 bouncing-emails per day and decide whether they are to be rejected or discarded. this is both tiresome and error-prone) to make life easier, i'd like to discard all bouncing emails in the future (as hans proposed to me in graz) the bad side of this is, that whenever an email is sent to the mailinglist from an unsubscribed account it will be silently dropped and you wouldn't know why it got "lost". to the lists it wouldn't make any difference, as such emails *never* reach them. so i no one objects, i will enable the new policy by tomorrow. mfg.a.dr IOhannes

new [hid] release + simple mapping objects
by Hans-Christoph Steiner 23 Nov '04

23 Nov '04

This version of [hid] fixes the crasher bug when you try to open a non-existant device. I am currently working on making a suite of objects for mapping controller data. I am making a number of objects like [mouse], [joystick], etc. which all output range (0 to 1 for axes). Then the mapping objects all take data of this range and output 0 to 1 so that the data can be easily mapped and scaled to parameters. Included are log, square root, and cube root; and exponent, square, and cube; as well as a basic smoothing object. The overarching idea for these objects is to make clearly defined, high-level objects for beginners and for rapid prototyping when using external controllers in Pd patches. At least point I am looking for ideas, comments, etc. about other possible mapping functions http://puredata.org/Members/hans/downloads .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

[hid] next alpha release
by Hans-Christoph Steiner 16 Nov '04

16 Nov '04

A few bug fixes, and a new naming scheme for buttons, and some other random, minor things. http://at.or.at/hans/pd/hid.html In this version, standard joysticks and mice are supported almost exactly the same in GNU/Linux and MacOS X. Tablets are supported in GNU/Linux, but Wacom wrote a whack driver for MacOS X, so tablets are not yet supported in MacOS X. .hc ________________________________________________________________________ ____ Man has survived hitherto because he was too ignorant to know how to realize his wishes.
