Re: [PD] resizing samples, noob question
Hallo, Andrew Faraday hat gesagt: // Andrew Faraday wrote: Hey guysI'm trying to create a patch that play samples 'at speed' but which is then variable. I need an equation to turn the number of samples in a table into the length of the sound file in seconds. Using this I should be able to divide one by the number of seconds and use that figure to set the speed of a phasor~ object for correct speed playback, is that right? what's the equation? You need to know the samplerate of your soundfile first - which may be different from Pd's samplerate as reported by [samplerate~] ! Lets assume your file's samplerate is the CD-standard 44.1 kHz or 44100 Hz. That means that 44100 samples are necessary to make up one second (because 1 Hz = 1/s) and the duration of one sample is 1/44100 seconds. So if you have a table of size X, then it has a duration of X * 1/44100 seconds or more general: duration in seconds = number of samples / SR in Hz If you use a phasor~ you need to get a frequency which is the inverse of the duration: freq(Hz) = 1/dur(s)= SR(Hz)/samples At this frequency the soundfile would play at its natural speed.[1] If you work with something like [vline~] to play your samples, you have to take additional care of the fact, that these objects deal with milliseconds, not seconds. A duration expressed in milliseconds is 1000 times the number describing the duration in seconds: 1 second = 1000 milliseconds 1.501 seconds = 1501 milliseconds The duration of a table in milliseconds is thus: dur(ms)= 1000 * duration in seconds = 1000 * (number of samples) / SR in Hz = (number of samples) / SR(Hz)/1000 = (number of samples) / SR in kHz The last transform uses the useful fact, that a frequency expressed in Hz is 1000 times the frequency expressed in kHz: 44100 Hz = 44.1 kHz Hint: If you work a lot with milliseconds it's often useful to think of frequencies in kHz. It's important to learn these relations for working with delays as well. You may want to make some abstractions out of it.

Of course beginners then still would like to use #0 in a message box. I'm not a beginner (though far from an expert), and I still want to use the unique identifier in message boxes. What, exactly, is wrong with that use case? Frank, I think you make quite a bit of use of $0 in messages in [memento], for example. If it's wrong, why does the idiom; [f $0]-[message $1( get suggested as a solution so often? In my opinion, that's just a kludge, avoiding the original problem. Looking back on the thread, I see this from Iohannes: $-args in message-boxes are a way to modify messages. since messages don't have a patch-context, neither have (their patchable instances) message-boxes. But the message-boxes *do* have a patch context; they live in an abstraction that has a unique identifier, which is sometimes useful to blend into a message.

Re: [PD] here I go again..dynamic abstractions
On Sat, 7 Feb 2009, Claude Heiland-Allen wrote:
I don't know why, but it makes parsing Pd patches 1000x less
straightforward than required (you need a two-phase parser that has a
special exception to detect message boxes and not expand dollars,
allowing the message box objects to parse them itself later, while
expanding dollars for everything else).
The way it works in Pd, Is that the parsing only cuts a patch into lists
of atoms, and then the evaluation of $ is a separate phase. There are two
levels of evaluation of $ in patches: one is because the patch is saved as
a sequence of messages that do dynamic patching of all of the patch.
Therefore, an objectbox containing $0 has to be saved as \$0, which gets
converted to $0 on the first evaluation, and the $0 turns into a float on
the second evaluation.
I don't think that this way of doing things is really bad, except perhaps
that it allows one to make patches that do weird things that don't get
saved back the same way (e.g. what if you edit a .pd file to put
non-backslashed dollars in it?)
That #X obj has this extra evaluation level compared to #X msg and others,
is not necessarily bad nor uncommon. The LISP languages generally have
that: there are a number of so-called special-forms in which arguments are
not evaluated, and some others in which only some arguments are evaluated.
This is how 'foo is a shortcut for (quote foo) in which the argument of
quote is not evaluated. In theory, you only really need that one
special-form in such a language, but the inventors of this figured out
that it was annoying to have to have only one special-form because it
needs too many apostrophes all over the place. In the end, though,
inventors of various LISP dialects could not agree on how many
special-forms there should be. (Macros allow the user to define its own
things that look like special-forms, but because of their evaluation
order, it also allows bypassing any non-evaluation too)
In Tcl, which is a distant cousin of LISP, things are different. Instead,
there is an extra level of syntax because all lists are assumed to be
quoted, a first parsing handles only { } \{ \} and a second parsing
handles $ \$ [ ] \[ \] ... not counting the [expr] calls, which are a
third level of parsing and happens quite often because it's explicit in
[if] [while] etc. The avoidance of having some kind of evaluation at the
first level of parsing makes it necessary to have the second level. My
point is that it's a tradeoff in the design of languages. If you remove
complexity in one way, it reappears in another way if the complexity is
necessary.
So, what could have Pd done differently? Perhaps two things:
1. Avoid the substitution in the first evaluation, so that most
backslashes aren't needed in the file format.
2. Use a different character for substitution in messageboxes, so that
message arguments are substituted using # or whatever (that's a second
level of parsing because # is not recognised at the first parsing level;
or would it??). But this makes people want to use $ to access
abstraction-args directly in it, and if that feature is considered as a
good thing, then you still need to either skip substitution in #X msg by
opposition to #X obj, or add another level of backslashes in msg.
(But that's all very hypothetical and nothing of that will change in pd)
I ran into this problem implementing PotatoData (basically a proof of
concept, it's a Pd patch interpreter written in Lua with minimal amounts
of C for DSP, can run some trivial audio patches) a couple of months
ago, and just ducked it completely - message boxes in my implementation
don't support dollars at all (nor commas or semicolons for sequencing
and redirection, but that's a separate issue). I wish message boxes had
used a different special character, it would have made life much much
easier.
I don't think it's a big deal. There are much more difficult things than
that, that you have to do to make a good interpreter and/or compiler. It's
just a bit confusing and somewhat easy to get wrong if you don't put all
of your attention in it, but if pd were different, this set of problems
would be replaced by another set of problems.
It's a mess. There are two similar concepts at work:
1. replacing dollars with arguments at patch execution time
2. replacing dollars with arguments at message passing time
There are three of them.
0. replacing dollars when loading patch (not normally used)
1. replacing dollars when loading #X obj
2. replacing dollars when message is sent to a #X msg box
The confusion arises partly because when Pd loads a patch, it's really
internally passing messages around.
That's why level 0 is there. It's never used by normal patches, yet it
makes it necessary to add extra backslashes everywhere.
Perhaps all this Pd parsing process is more difficult because it is not so
well documented (or the documentation has been forgotten

Re: [PD] here I go again..dynamic abstractions
From: Frank Barknecht f...@footils.org [1] Actually the $-variables 1,2,3,... in message boxes and those in object boxes aren't that different, because the contents of object boxes also are messages to Pd's objectmaker and they are used explicitely as messages when doing dynamic patching. Yes, this is the case -- and probably one of the more elegant parts of Pd -- but I still think this has less to do with Pd as an expressive language and more to do with how it's implemented. Even so, I think that a message box is not a message, any more than a message to objectmaker is an object; either way the $ values mean something different in each context -- in the messages to objectmaker they ultimately function more like environment variables or script arguments, where in message boxes they're a little more like substitution placeholders in something like a macro or a sed command. I think the current $0 meaning is consistent with this interpretation. I think my argument might be somewhat different if dynamic patching were fully supported with an official API - a huge step would be the ability to destroy individual objects with messages (can you?)...

[PD] one gui for diferent subpatches
Hi , i would like to use one gui to control diferent gem subpatches, one per time, for example i have 5 gem subpatches each one with a different gemhead but 4 of them are turned off, each one of these subpatches has a set of recievers from the gui, so with the gui i just control the values of the subpatch that is turned on, but the 5 of them are recieving the messages from the gui, Is this a good practice in terms of computacional consumption? Or if there is a difference if i separate the receivers from each subpatch and just have one set of receivers for all the 5 subpatches and just route the messages from the gui . Which is the best way of doing something like this? i ask this because this 4 subpatches turned off are still consuming cpu(they are very big), 4% por each turned off subpatch, this isnt too much now, but im planning to add a lot of more subpatches , so this subpatches that doesnt do anything are gonna eat my cpu. Which is the best way of doing this? maybe i should use dynamic patching? do you think is a good option for what im trying to do? any advice would be appreciated thanks pun. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] [PD-announce] Pure Data Basics: a Project-Oriented Workshop with Derek Holzer
Pure Data Basics: a Project-Oriented Workshop with Derek Holzer Wednesday 11 March - Sunday 15 March 2009 11.00-19.00 daily with one hour lunch break Final presentation Sunday 15 March, 19.00 Location: eNKa / ElsenStr. 52 (2.Hof) Berlin, Germany Telephone: +49 (0)176 20626386 Course Participation fee: 100 euros Registration is required for this workshop and can only be done via email to: e...@gmx.de Please register early to ensure a place. Places are limited to 12. Participants should indicate ahead of time what their background and areas of interest are (sound, video, sensors, etc) as well as give a short description of any project they might want to develop during the workshop. Pure Data is a powerful, free and open-source software environment for producing and manipulating sound, image, data and connections to sensors, motors and other physical computing functions, all in real time. Because the programming is done visually, many artists find it a more intuitive tool than traditional text-oriented programming languages. This 5 day workshop will cover the basic grammar and vocabulary of the Pure Data language through a mix of lecture and demonstration in the mornings and project-based mentoring in the afternoons. This workshop is open to those with no previous computer programming experience, however basic computer literacy is assumed as well as a working familiarity with either digital audio or video. A manual-in-progress for Pure Data by Derek Holzer can be found here: http://flossmanuals.net/puredata 5 DAY CURRICULUM DAY ONE: 1) Meeting PD: the interface and how to play with it 2) Basic PD: participants learn to make a simple synthesizer, and learn basic PD grammar in the process 3) Workshop: discussions of examples and work on student projects DAY TWO: 1) PD audio: more on oscillators, noise, delays, feedback, filters and signal analysis for all your sonic needs 2) Events in PD: participants explore the timing of events with sequencers, delays, messages 3) Workshop: discussions of examples and work on student projects DAY THREE: 1) Working with soundfiles: loading audio for use in samplers, granulators and other file-based sound manipulation systems 2) Basic GEM: how to create simple 3D objects, play videos and get camera input 3) Workshop: discussions of examples and work on student projects DAY FOUR: 1) Physical PD: an introduction to physical computing using Pure Data alongside a microcontroller-based board such as the Arduino or xAVR/HID--or even a hacked USB gamepad--to work with sensors, motors, lights, etc. 2) Workshop: discussions of examples and work on student projects DAY FIVE: 1) Workshop: discussions of examples and work on student projects 2) The Wrap Up: public presentation of student works + closing party. WHAT PARTICIPANTS SHOULD BRING Essential: 1) Laptop running Linux, OS X or Windows 2) Pure Data Extended installed from: http://puredata.info/downloads (please make sure it is Extended package!) 3) Soundcard 4) Headphones Recommended/Suggested: 1) MIDI controller/keyboard 2) Microphone/piezoelectric contact microphone 3) USB Joystick/Gamepad 4) Sensors or other input devices (please bring your own sensors if you are interested in working with them, as only a few light sensors will be provided at the workshop) 5) Small motors or motor-driven objects 6) USB webcam/Firewire camera 7) Arduino boards (Available from Segor in Berlin: www.segor.de) and/or the xAVR/HID board (http://www.1010.co.uk/avrhid.html, please inquire via the x webpage about preordering!) 8) Your own projects and ideas to realize! ABOUT THE INSTRUCTOR BIOGRAPHY Derek Holzer [USA 1972] is a sound artist with a background in radio, webstreaming and environmental recording. His work focuses on capturing and transforming small, unnoticed sounds from various natural and urban locations, networked collaboration strategies, experiments in improvisational sound and the use of free software such as Pure-Data. He has released tracks under the Nexsound, Sirr, and/OAR, Frozen Elephants Music, Mandorla and Gruenrekorder labels, and has co-initiated several internet projects for field recording and collaborative soundscapes including Soundtransit.nl. His recent projects include the opto-electronic audiovisual performance TONEWHEELS, solo performances for analog synthesizer and a manual for Pure Data. He was also co-curator of the Tuned City event for sound and architecture, which took place in Berlin during July 2008. http://umatic.nl/info_derek.html http://www.myspace.com/macumbista ___ Pd-announce mailing list pd-annou...@iem.at http://lists.puredata.info/listinfo/pd-announce ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
