Re: [PD] Smooth looping
Hi :-) Here's an example soundfile: http://footils.org/snd/23.wav With loopstart for example at sample 2912 and loopend at 5402, this looks pretty even in the array overlay, but if you listen to it, you can still hear a nasty rumble. I wonder, how to get rid of this ... I thing this is due to the loop's frequency? With transposition 0 you get about 17-18 Hz. As you transpose lower it should sound smoother but at higher rates the loop frequency is heard as a pitched sound. The problem is that a crossfade wouldn't really help here and I don't know any other solution (maybe filtering, but.). alabala -- ypatios ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Smooth looping
Anyway back to the looping: With the fix, I can smoothly loop sine-waves now, Oh, and as for the sinewaves, if you set the loop start and end points at exactly the beginning and ending of one period, then the loop frequency is the same as the frequency of the actual content of the soundsample, thus making the sound smooth, but also louder?

Re: [PD] Smooth looping
As I understand and as Matt already wrote, you wanted a transposition of the phasor~'s frequency (which would change the frequency of the loop but not the sample content), but instead you did the classic up/downsampling-of-the-soundsample transposition. (The distortion you get is due to the difference in spectral content, which should be richer as you transpose upwards since you read a longer portion of the sample. Also, the end of the loop changes which could mean a harder discontinuity.) I tried to fix the transposition and I also added an offset in the audio path before tabread4~ that corresponds to the beginning of the loop. And I'm sure you've already figured everything out, long before you got our emails. alabala On 23 April 2010 20:27, Frank Barknecht f...@footils.org wrote: Hi, not related to the thread on smoother audio in Pd, I am struggling with doing a smooth loop player for data stored in tables.

As you'll easily see, I use a [phasor~] | [*~ loopsize] | [+~ loopstart] | [tabread4~ table] idiom here.

Re: [PD] phasor~ and osc~ right inlet: exact timing

From what I know, the message comes one block late. but you can bang vsnapshot~ faster than the block rate and it seems it works fine. so there must be no one-block delay. alabala -- ypatios ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Generally, i had many confusing problems while testing that one. Has anyone else tried it??

[PD] peak amplitude in pd vanilla (was: [env~ ] vs [vsnapshot~ ]: which one is more cpu consuming?)
Hallo Frank :-), thanks for your reply (i updated the subject since the discussion moved on..) While you could bang vsnapshot~ at samplerate and keep track of samples in a list or so, this is a waste of resources. Something like tabsend~ or tabwrite~ probably is much better: Just write a number of samples into a table and then analyse that for peaks. There are some externals for that or do it manually. As I understand it (and hopefully i am not completely wrong..) you don't have to 'store' a list and 'then' read again it to find the max magnitude. It's as simple as the following: (some signal) *I* *I* [pd me...@samplerate] *I*/ [vsnapshot~ ] | [abs ] | [moses ]X[t f ] | [f ] So in the last [f ] you have the max magnitude stored and you can bang it to the [vu ] inlet say at a fix rate (which is the simplest way, it just requires a [metro ] banging [f ] and resetting [moses ]) I don't understand how using an array to store samples and then analyse it is more efficient than that. It seems to me you have to read 2 times: one to write the array in the fist place and one more to analyse it. a simple comparison: read-analyse vs. read-write-read-analyse Please correct me if i am missing something and post an example with the use of an array if you can. alabala -- ypatios ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] [env~ ] vs [vsnapshot~ ]: which one is more cpu consuming?
hello Also, you should know that the result of [env~] is something akin to a low-pass filter; the speed limiting from the original patch might be done more efficiently by squaring the signal and sending it through a (probably aggressive) low-pass filter before sending it to vsnapshot -- in that case it's possible that regular old snapshot with a larger [block~] size might work just as well, since you'll be sending a signal that doesn't change as quickly. You also need to take into I want to get the peak of the signal which means that any kind of filtering or other manipulation before (or after except rate limiting) vsnapshot~ is not a good idea. However, a lp filter seems to be a nice way to get peak-to-peak triggering (but only the triggering, not the actual values). I am currenty trying to implement that, using the already existing env~ to determine when the signal is falling at which point the last max magnitude is send to the vu, after some rate limiting, peak holding etc.. It seems to work but still needs optimization. account that doing message-level computations every sample might be fairly inefficient in general, and this is not something that [env~] I guess you have to trigger vsnapshot~ at sample rate to make sure you don't miss any value. I can't think of any other way. After all, there is no computation going on,other than reading groups of magnitudes and storing the greatest of them. is usually doing. Further, updating a vu gui every sample will probably be almost ridiculously inefficient -- try comparing the two setups with and without the vu connected (it may be that you have already taken care of this in the speed limiting and are not actually updating it every sample after all). That's right :) (It's amazing how cpu-consuming wish can be. And that with GUI objects that look so simple. I wonder how other audio software manages to run say a dozen vu indicators or fine-looking spectrum plotting tools, all at fairly high refresh rates with acceptable cpu losses.

Re: [PD] [env~ ] vs [vsnapshot~ ]: which one is more cpu consuming?
hello! By using [block~ 1], you're increasing the number of clock calls, and the arithmetic for finding an index is kind of wasted since the block is only one sample long. Maybe it would be best to avoid [block~] and bang vsnapshot~ with a metro set to 1/44.1 ms. You'd at least be reducing the number of clock_getlogicaltime() calls. Thanks for that. I had no idea that there would be a difference between the two. All this being said, the CPU load difference between these setups is basically nothing on my 2.5GHz MacBook Pro. I guess the differences would start to emerge if you compared dozens of instances of each. Yeah, in my tests i got notable differences from about 512 to 1024 instances. Hope that helps...

hello :-) They seem to reach the list. At least I received this and your previous mail. Thanks for that! What I still don't understand: Why do you want to compare those? [vsnapshot~] and [env~] do completely different things. Im trying to find a good way to monitor a signal. Since they both take signals and output messages that makes them candidates. The fact is that i use both env~ and vsnapshot~ anyway in a channel strip abstraction to feed the inputs of a [vu ] with the rms and peak level respectively. However, i need another instance of one of them to determine whether there is a (non-constant-zero)signal present at all. And i'm trying to find out which one should i duplicate. I did the cpu test and it shows that env~ is lighter. However, a snapshot~ triggered every 1024 samples (same rate as env~) is even lighter, which makes sense, since snapshot does no computing. I just thought that vsnapshot~ triggered at samplerate would be lighter than an env~, which seems to be a false assumption. Thanks for the tip :-). It would be nice though, to know also on a theoretical level. Which one should be more expensive and (maybe) why. (...) Anyways, while writing this email, it came to me that i don't really need an extra object(!) Instead of switching between pre and post fader mode in audio level, i do that in message level so i can use one of the two existing objects to determine if an active signal is present. The question remaining is: Is there a better way to feed a [vu ] in pd vanilla?

Re: [PD] vu analog style scale?
hallo IOhannes and thanks for your reply :) within Pd you are free to do whatever you want with your signal: e.g. you can run your internal signals in a range [-1e5,+1e5], and it will all be just the same (as long as you take care to scale the signals back into the standardized range before your [dac~]). there is no clipping in Pd [1]. i understand that 32bit floating point handling pd makes it possible to use audio signals in many other ways than just send them to dac to produce sound (like table lookup for example). the other benefit is that the manipulation of signals is much more accurate and this applies also after the conversion to fixed point signals. There is software that uses 64bit float internally for that reason. let's assume now that we need a vu just before the dac, e.g. to monitor the signal before it becomes analog. in this (rare?) case, why lose the upper 1/3rd of the GUI object? can you please answer the last question of my first mail? Would it be meaningful to offset the incoming values to make use of the visual space above 0dB or would it mess up the scaling? e.g. [osc~ 100] | [env~ ] | [-94] (instead of [- 100] would give about +3dB rms and the peak would be at +6dB. so you just consider +6dB as the real 0dB. thank you -- ypatios ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

hello is there an object, or maybe an abstraction, to retrieve a MIDI Note's name out of its MIDI Value? For instance, a 60 would retrieve me C4 (roughly speaking) and so on? I think that MAX has such object, but maybe I'm missing something in Pd's documentation... i made something like this once. although i am sure there are enough externals doing that.. alabala -- ypatios mtoname.pd Description: Binary data mtoname-help.pd Description: Binary data ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] message box issue with blank spaces
Hello Very interesting observation. i guess it has to do with the openpanel and savepanel objects. It's probably a special kind of symbol that represents the possible spaces (which in reality are no spaces anyway..) for compatibility with the OS. Obviously you can't create such a message within pd.

Re: [PD] [sigmund~] and [fiddle~]
But under the hood I think it uses a better algorithm. In my experiments it reports pitch faster and more reliable and stable than fiddle~. So if you can use sigmund~ I would recommend it over fiddle~ as a replacement. Back in the LAC 2008 in Cologne, I asked Miller that very question: what is the difference between fiddle~ and sigmund~. He said sigmund~ was the best pitch tracker he had programmed so far. So I guess fiddle is still alive just for compatibility reasons. alabala -- ypatios ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] tabread truncating array?
Hello, in this patch (B09) only the first 44103 samples of the file are loaded. Try using the -resize flag after the open message to the soundfiler (e.g.: [open -resize ../sound/voice.wav table18( ). But: you will also have to increase the chunk size.

Re: [PD] Variable length recording
Hi, i think the easiest way would be to write on the disk first (using writesf~), and then read the file to a table (using soundfiler and the resize flag). This way the size of the table will be automatically adjusted to match the size of the file. The downside is, you don't have access to the sound during the recording. If you do need access while recording (or if you just don't want to use the HDD) maybe you should prepare a table with the max recording length (according to your system capabilities, taste etc.) and after the recording is done (with a noteoff message for example..) you resize the table to the actual length of the recording by sending a message like the following: ; mytable resize $1 (where $1 is the length of the recording in samples) and at the same time you prepare the next big table for the next recording.. i guess, this is one flexible and economical approach.. but i'm sure there are many ways to do it. just told you what came to me first! sorry if i can't be clear enough right now.. :-) ciao 2009/9/27 Andrew Faraday jbtur...@hotmail.com Hey Guys I'm trying to record to a table between two given points (e.g. note on and note off at a given pitch) so that an array will resize the length of time between those points. So far I can only set the array size in advance and then record (using [tabwrite~]) from a given point. Any ideas how I'd record like that?

Re: [PD] slight problem with 8in 8out audio patch
well, i haven't really analyzed your patch, but i saw some numberboxes getting some set messages but without getting any bangs from somewhere else. this means they don't send anything to their outputs, ever, so in this case, the [del]s that follow get nothing. so maybe this is the problem. and a question: you have a reason for using the HDD instead of RAM? alabala 2009/9/25 Jilt van Moorst robotf...@gmail.com I'm having some trouble with this patch I'm making for an installation. I'll say upfront it has been years since I've touched PD.. but this one has me stumped what I expected to happen there are 4 zones, each with 2 microphones and 2 speakers. when moving through the zones your audio is recorded and played back the next zone like this enter zone 1 record mic 1 + 2 enter zone 2 record mic 3+4 playback recording from 1+2 over speaker 3+4 enter zone 3 record mic 5+6 playback recording from 3+4 over speaker 5+6 enter zone 4 record mic 7+8 playback recording from 3+4 over speaker 7+8 the recording is going more or less fine but no sound is being played back.. could anyone take a look at this patch ( you need audio card with 8in and 8out to test) and tell me what I'm doing wrong? maybe not waiting long enough before playing back the recorded files? the patch is here http://robotfunk.com/temp/contemplation008d.pd you need a 8in/8out to test it, would be much appreciated if someone would take a look at it.

Re: [PD] slight problem with 8in 8out audio patch
hi 2009/9/25 Jilt van Moorst robotf...@gmail.com OK, well 'visually' it seems like the number boxes are getting filled (i see a delay between the bangs for each stage, otherwise they would all happen at the same time) but I will look at it. yes, that is what the set message does to numberboxes: it updates their content (also visually) but doesn't let them send this new content to their outlet ;-) and a question: you have a reason for using the HDD instead of RAM? Yes. I (think I ) know how, unlike using RAM. Could you give me a hint on how to do the same in RAM? Instead of [writesf~] and [readsf~] try using [tabwrite~] and [tabplay~] (or [tabread4~ for more flexibility..) accordingly.

Re: [PD] run pd as admin under vista (was: help)
hi I'm running pd vanilla on vista and the only problem I've had so far was when i installed pd-extended on the same machine. It was a registry mess up which was solved by rebooting vista with last known working configuration option (i guess it just changes all the latest major registry changes back to the previous ones). Since i didn't really need pd-extended (i prefer using pd vanilla and just adding the extra libs that i need) my problems ended there. About the firewall, when you install and run pd for the first time you get a message from vista informing you that pd wants network access. By choosing unblock you will never see that message again and pd will do its work smoothly through the firewall. About running pd with admin rights, i think it is not necessary. I mean, i never run pd as an admin and it.. works! :-) And some extra info: I installed vista sp2 yesterday and had no problems with pd (or with anything else. Yet). Lastly, just to make sure that IOhannes talks to me next time we meet, i don't really like windows. I just have to work with it until i am brave enough for linux. alabala 2009/5/26 mrz zweit...@gmail.com hello, when pd works in safe mode, I guess your pd runs with admin rights. so try to run pd with right-click -- run as administrator. When pd works now, you can turn off this security lock completely: http://www.howtogeek.com/howto/windows-vista/disable-user-account-control-uac-the-easy-way-on-windows-vista/ note here, that vista updates allways change your user settings again, so i guess your pd runs not anymore since a genius vista update.. cheers moritz On Tue, May 26, 2009 at 3:28 AM, IOhannes m zmoelnig zmoel...@iem.atwrote: hi Farhood Kolahian wrote: Hi all, I work with pd in vista. since a week pd doesn't run anymore cuz every time I open pd I got the message that pd.exe has stopped working and windows can check online for a solution to the problem, so it will to give us a better idea of what is going on, it would (might) help a lot if you could also tell with which version of Pd you are experiencing the problem. e.g. does the problem persist if you uninstall e.g. Pd-extended 0.27 and install Pd-vanilla 0.33 instead, or the other way round? (make sure you grab the newest (stable) versions, not any of the random numbers i gave above) furthermore: problems with Pd on w32 usually exist because Pd uses a network-connection between the core-application and the GUI. firewalls usually don't like this, make sure that the Pd.exe process is allowed to make a connection (either by creating an allow-rule in your firewall, or by turning off the firewall completely (which i would not recommend)) finally: please make sure to use meaningful subjects. e.g. help is bad as our mailinglist software will interpret help as an administrative command (read: it thinks that you are asking for help about how to use the mailinglist, not about the topic of the list), and make the poor administrator of this mailinglist (read: me) to moderate your email. a good guide on how to post can be found at http://puredata.info/community/lists/Netiquette/?searchterm=netiquette ghmasdr IOhannes ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . http://www.myspace.com/moritzwettstein . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- ypatios ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] tabread4~~
Hello everyone! I work with pd for about 3 years. Right from the beginning (or almost..) i ran into the following problem: table look up with [tabread4~] is great for small array but, due to 32bit floating resolution, if the array is of a certain length and longer, look up can not be so exact. The result is distortion. I am not a programmer so i could not find the solution myself. I wrote then to the list and i got feedback for the problem but only info. No practical solution. Thanks to IOhannes there is a new object that takes 2 signals to specify the position for the look up which makes it way more precise (this idea came originally from my professor Gerhard Eckel). [tabread4~~] which you can find in the latest zexy lib. I tested the object but not in many ways yet it seems to be stable though. I am also making a small -help patch for the object which i will soon post (if it's ok with IOhannes..) So thank you IOhannes for your time and effort! I am really grateful.
