Re: [PD] suggestions for spectral weight anaylsis
Hi - try the dB threshold setting to leave out quiet grains. With normalization on, that can give you bad results because low level noise ends up being boosted, making the grain appear bright. Another problem is that a fixed window size will always get you audio slices that have mixed content - with a window size of 93ms, it's pure luck if you get a speech grain that only contains aaa. It'll likely have a little sss or something else in it too. So the solution there is to try to parse the audio based on content, not size. And using single value features (like brightness), BFCCs, or Bark spectrum, you're fine to compare grains of various sizes - the length of features like BFCCs/Bark spectrum depends on the size of the Bark filterbank, not the window size. About phasing...the worst case is that you end up overlaying the same grain with itself, but offset a bit. Don't know if that's an issue in your case. There is the stutter_protect option in timbreID to avoid repeated grains for concatenative synth, but I think you're just doing ordering? Anyway, it's a major problem with this technique, because the goal is to spit out sequences of timbrally similar grains. If things are working properly, that will always produce sequences of grains that have similar waveforms, and if you overlap similar waveforms, you get phasing/filtering! To be honest, I've only ever done two things: 1) add low levels of good reverb to smooth it out. 2) add controls for randomizing the grain size within reasonable bounds (like 90% - 110% of the window size). That at least varies the otherwise steady windowing artifacts, which can turn into a very audible flutter if your output overlap is high. One other thing to be aware of: if you do the analysis with a high overlap factor, you're more likely to overlap identical content. So an overlap of 1 is best from that perspective, but then you lose time resolution and end up with fewer grains. Or, taking things back to the first point above: if you have good segmentation based on content and not a fixed window size, you're less likely to have extremely similar waveforms overlap and cause phasing. With a reasonably small audio source (like your Lucier content), you could do this manually with labels in Audacity. Takes a lot of patience but I bet it would make a noticeable difference.

You'll see separate help files for [barkSpec~] and [barkSpec], for instance. So an [until] loop scanning your pre-recorded audio will be the fastest way for you to work on this. That's what's used in the 06/order.pd example. Just look in the [pd analysis] sub patch and you can change the feature from barkSpec to whatever you like (or whatever combination of features, weighted however). I'd recommend putting your audio into the timbre-space patch and plotting by different features there. That way, you can see how the vowels/consonants fall on different axes when using certain features. That'll give you some intuition on picking the best feature or combo of features. Last - ordering by timbre is always going to be fuzzy unless you can find a one-dimensional feature that reflects the timbre aspect you're after. Ordering by multi-dimensional features, you might make a big jump along one dimension for one step in your ordering, and then a big jump along a different dimension for the next step. You never know how much one particular feature is contributing the choice of the next step in the ordering. In terms of keeping it relatively intuitive to work with, fewer dimensions is better. For speech, I'd recommend trying [specBrightness] only, with a boundary frequency of about 2.5kHz. That'll separate the high-frequency consonants from the more formanty low-mid vowels. You should get a decent continuum with just that one feature. Hi, I don't have much time to be working on this, so I ended up adapting your timbre-space patch, and using the Brigthness (with 2.5KHz) in both x and y dimensions. This plots a straight line from vowels to sibilants, although the result isn't 100% straight. E.g. some sounds (or silence) that belong to an already existing group appear later inside other groups. But in general it works. A provisory result can be heard in https://soundcloud.com/experimental-music/i-am-splitting-in-a-room-v2 - it's part of Nicollas Collins' seminar on experimental music here in Berlin. As soon as I can I'll try to finish my analysis of your timbre-space patch, and improve the results. Or, if possible, even redo the patch myself. Another detail, do you have any suggestion on how to use your granulator and not get the typical phasing effects? I changed the envelope to a vline~ with a [0 0 0, 1 50 0, 1 50 50, 0 50 100( message.

Re: [PD] vjtools/videogrid was: pd gui: partial interface freeze
ok, first i checked and realized i had [change] to most of my hid output. so i tried without joysticks connected, [0] to [hid] and all metros off. froze the interface within seconds by quickly changing the input to vjtools/videogrid so i guess that's the object that's bugging me. i notice it does other strange things as well, like throw these errors: image create photo imga1bbe04 -file /tmp/vigrid_4.ppm (uplevel body line 1) invoked from within uplevel #0 $cmds_from_pd.pdwindow: no such object though it seems they appear without an interface-freeze. also i noticed some time ago, that when you use two instances together, they use the tmp/names for the same slots. i tried to hack some sort of uniqe identifier into the filename but that didn't seem to improve things. i might give that another try ... is there a usable alternative otherwise. i remember i saw these guys ones, which had something like videogrid, made inside pyext or so ... they said it worked absolute fine. thanks+cheers, ub On 18.01.2014 18:36, Py Fave wrote: usb/hid did this if i remember correctly. i solved it by usind a different build or another object: [joystick] but it was on windows i guess this is a known bug because [hid] is so useful perhaps someone has a better knowing of this .? or a workaround . 2014/1/18 u...@xdv.org mailto:u...@xdv.org u...@xdv.org mailto:u...@xdv.org On 18.01.2014 17:07, Py Fave wrote: i had the same problems while using gem objects some time ago it was because of text2d or text3d. right. considered parts of gem as the culprit, but then i'm fairly sure i did experience this, before i added text2d and text3d objects and i'm hardly ever running them [0]-[gemhead]. i'll give it a shot and remove them. you can remove some gui stuff too . replacing bng by bang for instance since i'm using them only as indicators not buttons, that's not an option. guess i could use data strcuturs for sliders, but that probably opens a new can of worms. and use [change] on your inputs to reduce the flow . i'll do that! only suggestions , i don't remember what was the problem but i solved it good to know, someone has seen it too. thanks! 2014/1/18 u...@xdv.org mailto:u...@xdv.org mailto:u...@xdv.org mailto:u...@xdv.org u...@xdv.org mailto:u...@xdv.org mailto:u...@xdv.org mailto:u...@xdv.org hey there, i've been having this heisenbug for some time and learned to live with it, but having fixed some real bugs on my patch, this is the last one on my list and i'd like to give it a go, but no idea where to start. symptoms are: some time into performing (20min to 1h) all the sliders, messageboxes, dials and bangs sort of get stuck, meaning they do not change their display state anymore. i can however still drag and click their active parts and their output will react accordingly, but none of this is being displayed. i should probably mention, that checkboxes still work correctly. i had hoped it would go away moving from pd 0.42 to 0.43, but it didn't. this is 64-bit linux (ubuntu 12.04), pd-extended (now ubuntu-package, previously self compiled from git) speculations include: from a gut-feeling i suspect something like an input overload, ie some input shooting messsages at an insanely high rate, so the element's message queue (if there is such a thing) stops passing things on to the display. i also suspect vjtools/videogrid as it messes with the interface, but does have a few issues, like race conditions between thumbnail creation and thumbnail display, esp if there's two of them. hid: usb joysticks could maybe freak out and overload the interface inputs anyway i can not see any direct connection between what i do and when it happens. re-opening the patch doesn't help, only restarting pd does. has anyone ever seen (something like) that? any ideas about how to debug, where to look or what to try? thanks + cheers, ub ___ Pd-list@iem.at mailto:Pd-list@iem.at mailto:Pd-list@iem.at mailto:Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -
