Re: [PD] [soundtouch~] pitch shifter for Pure Data
he katja. super work. thank you! m On Sun, Aug 21, 2011 at 09:00:24PM +0200, katja wrote: Hello, A few weeks ago I was reminded of my promise to share [soundtouch~], a SoundTouch port for Pure Data. I use this class since quite some time now, and had the code available on my website earlier on, but when I found that it could not work for Linux 64 bit I withdrew the project for a while. Reportedly, Olli Parviainen's newest version of SoundTouch is ready for 64 bit. I can not check this as I have no access to a 64 bit machine at the moment. Anyway, I have built [soundtouch~] binaries for OSX(fat), Linux32 and Windows32, and uploaded it together with source and help patch: http://www.katjaas.nl/pitchshift/soundtouch~.html SoundTouch is a time domain pitch shift / time stretch library, and I've built it into [soundtouch~] as a real time pitch shifter. It is suitable for the transposition of material with simple harmonic content, like voice, flute etc. The SoundTouch library is not perfectly adapted to real time processing, because you have to choose (at compile time!) between a build which produces dropouts during pitch factor change, and a build which has increased latency. I opted for the clicks instead of the increased latency (which is by necessity already considerable) in my binaries distribution, but if you want you can recompile according to your preference. To solve this clicks-vs-latency issue, if possible at all, would require a modification of the SoundTouch library itself. Apart from this issue, I'm fairly content with [soundtouch~]. Let me know what you think about it. If [soundtouch~] is considered a useful addition to existing Pd methods for pitch shifting, it may be worth the effort to try and solve the clicks-vs-latency issue. It is not a trivial task though.This time I'm not promising anything.

[PD] notes/questions from a beginner
I've tried getting into around with pd a couple of times before, this is my first concerted time. I've worked with a bunch of flow-charty programming environments in the past (Unreal Engine's kismet is the slickest I've come across - http://odedge.com/forums/ut3_kismet_04.jpg ) - pure data is taking a bit of getting used to (most of this is due to the fact that it does special things, some things feel a bit more avoidable, other things feel frivolously subjective :P ). Here're some of the things that stuck out for me (some might be due to ignorance on my part, I'd love to have things cleared up :) ): 1 - Inlets/outlets too small for me to accurately click on (touchpad) - checking on pd-dev, they can be visually reskinned, but their actual clickable size can't be changed. [ so I guess this one has been responded to, but might as well repeat it ] 2 - If I have an object selected (that's to say pressing buttons to edit text in it) I can't find any key-combination that will delete it - I have to deselect it, then press the mouse down on it, then, while holding the mouse button down, press backspace? (this is an uncomfortable manipulation on a laptop w/ touchpad) - on OSX at least, a shortcut like cmd+backspace would be quite idiomatic for this. 3 - I can drag lines from outlets to inlets, but not from inlets to outlets. 4 - is there a shortcut for deleting connections? something like ctrl+click would save me a lot of time. 5 - is there a way to type numbers directly into a number box? clicking+dragging, or pumping them in via a message, doesn't feel good to me. 6 - shortcut for opening help of selected item would be...convenient for me I'm still working through the tutorials, and am enjoying the experience overall :) ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] notes/questions from a beginner
1 - right. You can't fix this without refactoring the canvas_motion stuff in g_editor.c. I'm still not sure why these events are handled in c and not with tk bindings. 2 - There isn't a key combination that will delete it (and doesn't cmd-Backspace just delete the previous word anyway?). The best would be to have ctrl-a select all text, then you could just do ctrl-a and backspace. 3 - Hm, I never thought about that one. Btw- you also can't connect an object's outlet to one of its inlets with the mouse (though you can do it in other ways). 4 - Nope. There are lots of ways this could be improved. (Shift-drag for bounding box around wires instead of boxes, then Backspace, would be one way-- off the top of my head.) Elegant patch editing is not currently a part of Pd-- even the Autopatch feature in the Edit menu assumes that all objects only have a single inlet and a signal outlet. 5 - click in runmode (but there isn't any visual feedback). 6 - I guess you could add a key binding, but right-click and choose Help seems perfectly fine to me. -Jonathan From: Stephen Lavelle analy...@gmail.com To: pd-list@iem.at Sent: Tuesday, August 23, 2011 8:16 AM Subject: [PD] notes/questions from a beginner I've tried getting into around with pd a couple of times before, this is my first concerted time.

[PD] #store and getting pixel data from a movie file
Hi I hope to ask for some tips regarding obtaining values from a loaded image/movie file by using gridflow ? #store gets can get rgb values from a specified pixel position but any advice on getting the whole dimensions at once (or any other techniques in getting gridflow to output values from a movie file such as movement, luminosity or anything)? ...also is there support for mp4 in gridflow? the file format being the same as mov (I think?) Thanks all for any thoughts ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

An [osc~] multiplied by will sound louder but it won't actually be louder than an osc multiplied by one (the amplitude at the output will still be between 1 and -1).

The easiest way to do that is to play the loudest sound first and adjust the volume so that it's loud but not too loud. Then everything else you do will be quieter than that.

Re: [PD] making puredata headphone-safe
Doesn't hurt here*. I guess we're getting into a subjective realm-- but if someone adjusts their master volume for [osc~ ]---[dac~] to be as loud as possible without being uncomfortable, I have a hard time believing that they would be comfortable with [noise~]---[*~ 99]--[clip~ -1 1]--[dac~] at that same master level. -Jonathan * I adjusted my master volume so that the clipped noise was at a tolerable volume, then checked [osc~ ]--[dac~] at that same level.

Possibly editmode, but also because there's no indication that the box contents are editable by pressing keys (no caret, c.). Is there a reason it's disabled in editmode? You can do it from editmode by ctrl-clicking the numberbox and then typing (ctrl key puts you in run mode while it is held down).

I think it actually depends on your sound card whether or not this is true with Pd. I might be mistaken but I am pretty sure some sound cards will let you output abs(x) 1. Hmmm actually this doesn't make sense to me if the driver is accepting a 16 bit signed int. Can someone confirm whether this is the case? Incidentally, if I recall correctly, Miller told me that he uses a set of small, cheap speakers when doing experimental stuff so as to save ear damage. At least I think it was Miller. My own ears are a lost cause after years of punk gigs so I don't have this problem.
