Re: [PD] How to Mix 2 audio files into 1?
It's also worth mentioning that you can do this quickly in non real time by going through the tables for each source file, adding the values sample by sample, and writing the sum to a 3rd table. Then use a [soundfiler] write command to export the mixdown to a .wav file. If you use [tabletool]'s add method to get the sum, it'll be faster than going through the tables with the [until] approach.

Re: [PD] suggestion for onset detector - timbreId?
Hi João, timbreID has [bark~], which uses a technique based off of bonk~, but with a filterbank built from the Bark scale. It also has some special features that I've found useful. If you're looking for non-real-time analysis, there's [bark], which analyzes whole arrays as fast as possible and reports attack locations in seconds. I use it to generate text label files for importing into Audacity to take advantage of the export multiple command there.

Hi Eran, the order-perc.pd example in that same 06-timbre-ordering directory shows how to do those kinds of things.

Re: [PD] tabread2~ noisy output
Hi Peiman, I notice a few things: 1) your soundfile is being truncated to 400 samples 2) you're loading the left channel of your stereo file into both arrays 3) after calculating the correct frequency for phasor~ to play at normal speed, you're multiplying by zero. With 3), maybe you have that there so you can scale the playback speed with a control later. But re: 1 2, try a message to soundfiler like this: read -maxsize 6.24e+06 -resize $1 test_L test_R That will increase soundfiler's default maxsize so your complete sample can be loaded. Also note that with the read command you can list 2 tables to load to with stereo audio files. You had those tables listed in separate messages…with 2 separate read calls, soundfiler is starting over each time and has no way of knowing that you want to continue where you left off. I didn't listen carefully with headphones, but after those changes I didn't hear an obvious difference between tabread4~'s playback of your file vs. my web browser's.

Re: [PD] pointcloud in Gem (timbreID) and performance
Hi, Yep, list parsing is probably the issue. Without the snapshot trick, every render frame sends data requests to the [timbreID] object, and lists are output in response. Those lists have to be parsed to get the coordinates for points. That's the price for storing/manipulating all the analysis data in [timbreID], but you could definitely do everything it does internally via patches, and then have more flexibility. Or you could still use [timbreID], but do all the data requests in advance and store the results in tables.

However, when you try to do this with a sample of 4.5 minutes it doesn't work any more because the list parsing and gemlist repeating for each and every point (then about 900) at framerates of 10 fps is to heavy on the CPU. William resolves this by rendering it once and taking a snapshot of the scene. that works nicely, but is not an option for my work, as i want to see the 3d space and navigate in it real-time. I was wondering if this could be done more efficiently and where to start. I think the points should be rendered in a glsl environment and the list of every points position should be static (in a matrice?) and not called and parsed by [list] objects at a rate of 9000 times per second. Unfortunately the geometry shader example doesn't work here, i was hoping to get some clues from there. william has a tiny image of a point cloud on his page: http://williambrent.conflations.com/pages/research.html#timbreID max ___ 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 - http://lists.puredata.info/listinfo/pd-list -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I tried single buffer mode with each metro tick banging the gemhead and then clearing the gemwin, but got jittery results with the video stream. I haven't looked at triple buffering, is there some documentation you could point me to on that? The reason I want faster than screen rendering is that I'm doing video tracking. If the control streams from the tracking algorithm can be updated faster than the refresh rate, that would be ideal.

So there's not option for this, but to use only the right entry?

Re: [PD] vline~ precision, or sequentially segmented playback of a buffer
I'm also wondering about the timing of tabread4~'s offset inlet being updated. I get fewer clicks by tossing most of the patch into a subpatch with [block~ 1]. I haven't checked really carefully, but that does seem to make it so that clicks only occur where there are gaps in the log.txt file. Another thing is that, even though vline~ can start ramping between block boundaries, there's still a lower limit involved. You can see in the attached patch that you can't get a period less than about 88 samples (or 44 samples for each half of the triangle wave). Seems like that shouldn't be affecting you though, since you're retriggering every ~180 samples.

Re: [PD] vline~ precision, or sequentially segmented playback of a buffer
Hi João, The first thing I'm wondering is if you want each segment to have the same number of samples. I see that the time to scrub through each segment is the same (181.818 ms), but then the length of segments in samples varies. I guess the pitch shift that happens from this isn't a problem? Also, it looks like not all of the boundaries in your log.txt line up. Starting on segment 330, there are gaps now and then: 198694 207333 181.818; 210909 219994 181.818; That explains the phase discontinuities (at least some). I know this is just your abstracted problem, but maybe similar unexpected gaps exist in your main patch? On Sun, Mar 11, 2012 at 6:05 PM, João Pais jmmmp...@googlemail.com wrote: Hello list, continuing with a topic I started some time ago (but couldn't continue the discussion), I've made a simulated version of my patch to explain the situation. The full patch is too complex, and would need audio files to be sent with it. The context is as follows: An audio file stored in a buffer is played in small segments in a forward-backward sequence. Each segment is played after the previous, with no gaps in time or reading point. First segment goes as 0 - 8638.86, 2nd as 8638.86 - 17277.7, 3rd as 17277.7 - 25916.6 , etc. All segments are triggered at the same pace, in this case 181.818 ms. You can see all the segments in the [textfile]. Ideally, the original audio file would be reproduced with no difference to the original - besides the playback pointer going forward-backward. But when playing back the segments, after the first initial moment with almost no problems (only the clicks when playback changes direction), clicks start to appear at each segment - from around sample 229K onwards. Since I'm using [vline~], I thought that the timing of the reading point related to the audio blocks wouldn't be a problem. But, if you record the output and look at the audio file, you'll see that the clicks come from a out of phase moment, and then the wave continues. My question is: am I doing something wrong with the circuit? If not, is there an efficient way of achieving a similar playback of a stored buffer? I hope everything is clear. The original patch is a monster, but this version sums up what's happening. Btw, in the original patch all the values are calculated in real time. But with the recorded version the audio sound just the same. The original audio file is 5m18s long. Will the be any round-up problems while calculating the segment coordinates to tabread4~?

Hi Joe, When you're searching for a good minvel setting, you should watch the 2nd number in the list from bonk's right outlet.

Re: [PD] speaker recognition with pd ?
2. The Mel-Frequency Cepstral Coefficient (MFCC) of the FFT (Fast Fourier Transform) of a waveform is a good timbral identifier. William Brent's TimbreID objects are good instantaneous timbre identifiers using this principle, but to build up a sophisticated model of a human voice (robust enough for speaker ID) you need to work out how to build a database. For an instantaneous MFCC identifier using an internal database, check out Michael Casey's soundspotter PD external. Aside from the different analysis objects like [mfcc~], there is an object in the timbreID library that makes it easy to build a training database and make comparisons on the fly. But like Ed and others are saying - the problem is how to interpret the stored data. I never dove into the voice recognition problem, but my understanding is also that the magic is in the transitions. timbreID will help you get all the data you need if you can go the Markov model route. On the other hand, if I were going to take a stab at a simplified system based on isolated sounds, in general I'd guess that features of pure vowels would be more helpful in distinguishing between different speakers than features of sss sounds or consonants. -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Spectral focusing
Hi Zax, Maybe a straight up vocoder is too primitive for the kind of sound you're after, but who knows... For what it's worth, I have a vocoder patch in my timbreID examples package with filters that are spaced evenly in Barks. You can also tune the relative amplitudes of the filter outputs. Of course, it still might just make everything sound like a robot :) On Wed, May 25, 2011 at 9:24 PM, e...@mx.kein.org wrote: Hello list, After a few years of maxing I migrated back to PD about a year and a half ago and haven’t looked back.

I tried cross-synthesis with a harmonic signal, which is ok, but what I’m actually trying to do is to “tune” a field recording, in a way, so it can have harmonic relations to a live instrument. I played with the pvtune~ object from fftease which is nice, but the results end up sounding a bit autotune-ish. And I also tried driving a few vcf~ filters with frequencies running from fiddle~/sigmund~ but the fundamental from these objects is too erratic and it sounds very unnatural. Wishart describes in his book a technique he calls spectral focusing, which relies on lpc. He says that lpc can be set to generate a filter bank which is distributed evenly with respect to pitch, but I’m not sure I understand what he means and how it can be done in PD. lpc seems to output a set of amplitudes for the coefficients. Can I set the filters to frequencies of my choice?

Re: [PD] TouchOSC and Pure Data on OS X
OSCulator is really fantastic, yes. In this case though, I think it's easier to keep things streamlined and route everything in Pd. I didn't think of it until your reply, Richie, but I made this abstraction for touchOSC's simple layout. Just invoke it with a port number [ipad-interface 8000] and you'll get all the parsed data flowing to well-named sends. For instance, to get the data from fader 4 on page 1 of the simple layout, you can receive from [r ipad-8000-p1-fader4]. Comb through the rest of the patch to see how other sends are named.

Another thing that occurred to me is that since the scratchy noise part of the viol sound is likely what's making the tracking jumpy, you could try to remove the noise. I've been working on an external that lets you rescale the amplitudes of harmonics in a pitched signal. There's an early draft on my website - it's called [pitchEnv~]. Using that, I scaled all the harmonics of your sample to 0, so that all the pitch related components are erased from the signal. The attached wav file is what's left...basically all the scratchy noise. Then I tried subtracting that noise from the original signal (delayed slightly based on the time it takes to do this analysis), and it did clean up the noise some. It wasn't perfect, but with some work this could produce a signal you send to [sigmund~] that would be more easily tracked out. I might have time to fiddle with that later, but if you download [pitchEnv~] you can give it a shot too.

Re: [PD] Sigmund~ and tracks.
I'm not completely clear about the continuation flags? I can see from the help file that they're there but what do they mean? On every analysis period, several track reports are output in a burst. These provide the frequency and amplitude of what [sigmund~] considers the most important components in the spectrum. It does its best to find continuity between the components in the current frame and those in the previous frame. Of course, sometimes it fails to connect things nicely, sometimes there are new components that weren't there last time, and sometimes old components disappear. That's why each track report has its own flag. If it's a new track that flag will be 1. If it's a continuation of a previously existing track, the flag will be 0. So you can do some patching logic to make sure that continuing track information is always routed to the appropriate oscillator in your bank (i.e., the one that is already tuned to roughly that frequency). If you have a new track with a flag of 1, you'd want to send that track information to a silent (currently free) oscillator in your bank, and fade it up to the desired amplitude so that you don't hear a click from sudden change in frequency. Perhaps this should be a new thread but why does sigmund have a frequency range of 100,000hz, and what would be a decent useable range from practical experience? Strange - I never read that part of the help patch carefully. It's even stranger because it actually says the default maxfreq is 1,000,000 Hz, not 100,000. I'll assume there's a good reason for this that I'm just missing. But otherwise I think I'm understanding that setting in the same way you are: it puts a cap on the highest spectrum component that you want [sigmund~] to report. Assuming that's correct, I'd say you're safe capping it at 15kHz. That'll keep the number of oscillators you need practical without losing serious high end detail. But I think the best advice is to trust your ears...with some sounds (like speech) you might not be disturbed if you cap it at 10kHz. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Sigmund~ and tracks.
Hi Julian, I just looked at the patches and I hear what you're talking about now. The erratic changes are because it's really hard to get nice smooth tracks by analyzing this kind of signal. With violin samples I got useable results, but the rougher timbre of your viol has a lot of high frequencies that emerge and disappear unpredictably. I think that getting 48 stable tracks out of it is probably a lost cause...even with only 10 it was pretty bad with sigmund~'s default settings. The only way I could imagine improving things is to use the flag that shows up with each track list to indicate whether it's a new track or a continuation of an old one. With that information, you could try fading in new tracks on free oscillators in the bank to avoid the sudden discontinuity when frequency jumps by a huge amount. Data from a continuing track could safely be sent to the same oscillator. I guess you could also EQ it to get rid of those unpredictable high frequencies - I plotted the spectrogram and the most troublesome ones are above 2500Hz. Of course, that would also put a big damper on the timbre you're interested in... I wish I had a great solution for you, but this is a tough one. Assigning frequencies to specific oscillators in your bank based on track flags really seems like the best bet.

Re: [PD] Sigmund~ and tracks.
Could you make a simple example patch that demonstrates the rhythmicized/pulsed result that you don't like? Without knowing exactly what's going on in your patch, my first question would be whether or not you're smoothing the frequencies and amplitudes with a [line~] or something else. Maybe sudden changes due to fleeting tracking errors cause glitches that pulse in sync with the analysis period? With a violin as input you should get a reasonable enough spectrum to get stable harmonic tracking with a window much smaller than 65536. The low G on a violin is 196Hz, so the bin spacing you'd get with -npts 4096 would give plenty of resolution for catching multiples of that fundamental and higher ones, and only 92ms of extra delay. The hop setting you choose will just affect how often the information is updated (and CPU usage too). You should expect to deal with some temporary tracking errors during moments like attacks, where components of the spectrum won't be in a perfectly harmonic relationship. Going beyond 131072 points using Pd's built-in mayer_fft() has given me garbage as output in the past. Maybe someone else knows something about this limitation? On Wed, Feb 9, 2011 at 11:41 AM, J bz jbee...@gmail.com wrote: Hi all, I'm doing a piece with a viola d'amore (7 string viol) where [sigmund~] is analysing the live input and feeding 48 tracks/partials to a bank of 48 [osc~] for resynthesis and a bit of jiggery-pokery, mainly reversing the amplitudes so the quietest partials are the loudest and vice versa. The viola is playing long(ish) single notes between 1-3 seconds and the problem I am having is that when sigmund processes the partials they come out rhythmicised/pulses which seems to be a combination of the 'hop' and 'npts' settings. As the values for hop and npts get higher the pulses get longer up until my current huge setting: [sigmund~ -npts 65536 -hop 65536 -npeak 48 tracks] when the partial frequencies balance out into steady lines. I have also tried -hop 131072 which works too but trying that with the -npts completely locks pd. The problem I have now is that there is a significant delay between the beginning of the processing in comparison to the viola and worse still is the overlap after the viola has stopped playing. Also the viola notes are indeterminate so I can't just set a cutoff to sync the two together. I could use the input of the viola to gate the tail of the processing but I am currently using a combination of [env~] and [lop~] so that as the performer plays his amplitude controls the processing in reverse, so when he's loud the processing is quiet etc. I suppose I can add another layer on top of the end I am aware that the gap between the two sounding events is caused by the huge window sizes I am using and that there may well be no way around this to get the kind of sound from the processing I'm looking for, i.e. without the pulses, but I am wondering if anyone has any tips and tricks I can apply to try and bring the two sounds, viola and processing, closer together. Or ideally some way of achieving the smoother processing with lower npts and hop settings. This is for a live performance btw.

Re: [PD] tabletool
Thanks for looking. The multiple object library vs. single multi-function object question is a good one. Personally, it just seems more tidy to me this way, and I don't believe there's any downside to having all the functions packed into one extern. All the memory is allocated per function, so if you only use the sum function, (I think) it shouldn't be significantly different than a separate extern for summing. There is definitely something more Pd-ish about the multiple objects though. I'm open to changing it... For now I'll start using it and see if I ever have a desire to make it the other way.

Re: [PD] pix_motion_sector
I'll update the helpfile for [pix_motion_sector] to include a subpatch that does the same thing with [pix_crop], [pix_movement], and [pix_dump]. I think I might also change the source and try taking the distance between current/previous frames using all RGB info instead of a greyscale approximation. The speed issue aside, that may be a significant difference from [pix_movement] worth investigating.

The process of summing the elements in a large table is much faster in an extern than with an [until] loop. In the case of [pix_motion_sector], what's the easiest way to duplicate the functionality of reporting % of pixels changed in the region? Is there an obvious way to count up the number of pixels that crossed [pix_movement]'s threshold in the cropped region? [pix_dump] ?

Please correct me if I'm wrong, Doesn't having these as externals instead of abstractions, make it significantly faster/efficient? particularly if you have many of them? no not necessarily. the overhead for message communication between objects is usually quite small, compared to the pixel operations. you would only need [pix_crop]-[pix_movement] without the [pix_separator] (since the crop will have to allocate a new image anyhow), thus no need for the extra copying of data. the only speedup you could expect from pix_motion_sector (i haven't looked at the code), is that you wouldn't have to copy the data for cropping at all, but only use the pixels in the ROI. as for williams argument, that you need less objects, i would suggest looking into abstractions :-) it's definitely less lines of code (at a minimum 10 lines of Pd code) and still only a single object... mfgasdr IOhannes best, J _ _ __ ___ _ _ _ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801 ___ 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 - http://lists.puredata.info/listinfo/pd-list -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkvtC0wACgkQkX2Xpv6ydvTVNwCgot+wBAkpacUIHBFR3Fg5OmWV xhAAoITZ7wN077ETVr58rSVE9iunYybB =jYk3 -END PGP SIGNATURE- ___ 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 - http://lists.puredata.info/listinfo/pd-list We have nothing to fear from love and commitment. - New York Senator Diane Savino, trying to convince the NY Senate to pass a gay marriage bill -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] tabletool
What's more tidy about it ? You're right - not much. If you wanted the mean, sum, and length of a table, it would be 3 message boxes and one [tabletool]. Otherwise it would be 3 bangs and 3 instances of [tabltool/whatever]. Not a big difference. I guess in this case I just lean toward the method-centric side as you point out. And your point about sinesum is exactly where my leaning comes from. You can send sinesum write read const resize to a table, so there's already a history of methods there. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
