[PD] Extracting textfile columns for audio
Hello PD list I'm trying to extract one of three number columns from a text file to drive the pitch of an audio oscillator. I have the .txt file reading all 3 columns of numbers into an array at present but I only want the second column. Ideally I'd like to extract the 2nd column before being read into the array but another solution in this case may also be limiting the numbers read from the array to the oscillator to within a particular range (i.e. the number value range of the 2nd column; 840 - 890). Though the latter wouldn't provide a pure solution it would be workable in this case. As you may have guessed, I'm grapping with pd fundamentals here as an abolute beginner, so I'd really appreciate any suggestions/ patch examples/ explanations etc. thanks Toby - Yahoo!

Re: [PD] Extracting textfile columns for audio
A more workable solution might be to use the IEM matrix object set, which is designed for exactly this sort of tabular data. I hacked together a pretty good preset saving system a month or two ago using them. You might have to format the txt file you are using a bit to get it to load, however. Check 5.reference/iemmatrix/matrix-help.pd (at least on Extended) for details. d. toby zardoz wrote: Hello PD list I'm trying to extract one of three number columns from a text file to drive the pitch of an audio oscillator.

Re: [PD] Extracting textfile columns for audio
hi toby since [textfile] doesn't provide any mechanism to jump to a certain line, you need to step through all lines from the beginning. this conflicts with your intention to only read certain lines out, not all of them. you could solve this conflict by appending a [spigot] object to [textfile]. [spigot] lets you choose, if messages should get passed or not, by sending to its right inlet '1' or '0'. a solution would be to set [spigot] to '0' until [textfile] reaches the line you want. then you could set [spigot] to '1', so that the output of [textfile] is sent to the array. if you are on pd-extended or you have the zexy external installed, then you could also use [msgfile] (on pd-extended you may need to create a [import zexy] first). it works similar to [textfile], but provides more 'commands'. you could send it a 'goto 2' message in order to set the read pointer to line 2. sending it a 'bang' now, will let it output line 2. roman On Fri, 2007-06-22 at 12:11 +0100, toby zardoz wrote: Hello PD list I'm trying to extract one of three number columns from a text file to drive the pitch of an audio oscillator.

[PD] Problems using M-Audio Soundcards with a Dell Laptop Computer
After making tedious and exhaustive tests I finally discovered that using an M-Audio Audiophile Firewire Sound Card connected to a Dell Inspiron Laptop produces random little chirps while recordings that are -to my present knowledge- unavoidable and due to some kind of incompatibility between those two devices. Of course I did all the Audio optimizations on the system required and recommended. The Customer Service of M-Audio said laconically that it may be likely an IRQ conflict and gave me elemmental and useless advices already known by any newbie computer user. I tried to reconfigure all the system and to leave the less IRQ in use as possible. It did not work either. The curious thing is that with other laptops I had no problem recording with the Audiophile Sound Card while using a different sound card (Old but very good Edirol UA-5) I could use the Dell Laptop successfuly. If you are experiencing a similar problem and can tell something about I will appreciate any help. Anyway, think it twice if you have a Dell Laptop and you are to buy an M-Audio Sound Card or vice-versa... :) Most Cordially Isi Looking for earth-friendly autos?

Re: [PD] arduino+solenoid concert
So, SMS is signicantly slower because it uses ASCII conversion ? Interesting. Even at high baud rates ? SMS is aimed at ease of use and precision. Although I am surprised to ear about SMS's and Pduino's speed problems. I made an installation with an SSC-32 servo controller controlling 24 servos connected to PD. The SSC-32 is based on the SAME chip as the Arduino and uses a communication protocol VERY similar to SMS and I never experienced any problems. Maybe you are not keeping your messages simple enough?

Hi, it would be very helpful to change the behaviour of gemmouse a little bit (to get similar results to the translation of objects in the gemwindow). [gemmouse 8] should normalize to the height (like gemwin) and not to the width. given a rectangular gemwin any aspect ratio (no difference between 2:1 and 1:2...) always normalizes to the height and sets (with the default view) the top and bottom borders to +4 and -4 gemmouse 8 on the other hand normalizes to the width. this makes it very difficult (unpossible?) to build mouse interaction with variable window sizes. another feature wish: to be able to tell the dimensions of the gemwin. esp. after resizing by mousedrawing. thanks, marius. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

the problem with timer is, that it only sends an output, when banged. you could bang it with some insane rate using a [metro 1000] and according to the measured (real)time, you send a bang or not. this approach would *might* work, but it has several disadvantages, if i do understand the underlying architecture of pd correctly. first, you cannot be sure, that each desired time will be triggered. lets assume you want to schedule the next 'bang' to 43s297ms, but the output of [timer] maybe is '43 296', '43 296', '43 298'. in that case '43 297' won't be hit at all. then i think, that this approach wouldn't be accurate at all, since there is no logical time involved. the advantage of logical time is, that it doesn't matter at all, when the [metro] object is processed by pd, the output of it will be accurate (as long there are no dropouts). with a purely realtime based solution, you'll never know, when exactly the object, that does the time measuring, is processed. the time, when [timer] receives your bang is not exactly defined and can happen anywhere between now and the amount of your buffersize later. correct me, if i am wrong, but as i understand pd, there will be no accurate realtime based solution. roman On Fri, 2007-06-22 at 17:56 +0200, Enrique Erne wrote: hi has anybody built a dropout save metro ... say if pd freezes for a while and comes back that the metro would still be in sync with the 'outside' world. that would be very nice in a life situation. some ideas ? do you think it can be done in plain pd? i failed when i tried to measure the periods between the 'ticks' and calculated the new delay time. i just discovered [time] from zexy which is the system time ... has anyone yet built a metro with [time] ? :) eni ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] dropout save metro
one solution, that might would work, came to my mind. you could run two instances of pd, one does only hold a [metro] and has a slightly higher priority than the other instance. the second pd does all the audio stuff and therefore might have some dropouts. now you could send the output of the 'dropout safe' [metro] to the audio instance of pd. this would be a clean solution, but it requires some connection between the two instances of pd, most probably a tcp-connection. due to this connection, this approach might be inaccurate as well. roman On Fri, 2007-06-22 at 19:06 +0200, Enrique Erne wrote: i think your totally right... too bad.

frank mentioned using an audio connection. with an audio connection
between both instances you wouldn't have any glitches. the main problem
is how to 'encode' and 'decode' the audio signal, so that you don't lose
sample accuracy. there are possibly many approaches, but one comes to
mind using [pack~] and [unpack~] from zexy. dependent on when the 'bang'
from the metro happens withing a block, you could encode that time into
the first sample of a block with a list like '23 0 0 0 0 0 . ' sent
to [pack~] . ('23' means, that the bang should be triggered at the 23th
sample of that block). on the receiver side, you could use an
[unpack~]
|
[$1]
construction to 'decode' the audio block.
hope, that makes sense..

and therefore might have some dropouts. now you could send the output of
the 'dropout safe' [metro] to the audio instance of pd.
this would be a clean solution, but it requires some connection between
the two instances of pd, most probably a tcp-connection. due to this
connection, this approach might be inaccurate as well.
frank mentioned using an audio connection. with an audio connection
between both instances you wouldn't have any glitches. the main problem
is how to 'encode' and 'decode' the audio signal, so that you don't lose
sample accuracy. there are possibly many approaches, but one comes to
mind using [pack~] and [unpack~] from zexy. dependent on when the 'bang'
from the metro happens withing a block, you could encode that time into
the first sample of a block with a list like '23 0 0 0 0 0 . ' sent
to [pack~] . ('23' means, that the bang should be triggered at the 23th
sample of that block). on the receiver side, you could use an
[unpack~]
|
[$1]
construction to 'decode' the audio block.
hope, that makes sense..
(sorry for spaming so much about this topic)
i just realized, that you couldn't send higher values than '1' over an
audio connection. therefore the 'encode' should scaled down in order to
fit into the transmittable range.

i think your totally right... too bad.

Re: [PD] Turning on/off an installation
Hi Alexandre, I've always kept my machines on, and my projectors/screens are the things that get switched on and off. Most of my installations deal with previous days anyhow... I've has installations running for many weeks on constantly. The current one uses [shell] to turn dpms on and off on the monitor to make it suspend, and turns off the camera movement according to a schedule in the patch. Are you worried about wearing out the HW? (mechanical parts?) B. Bogart Alexandre Quessy wrote: Hi all, I was wondering if someone has an idea on how one could create a switch to turn on and off an installation. I was thinking about either a push button to turn it off, or a web interface. Maybe one of those two things could make Pd (or PHP) write to a file that would be parsed by a cron job every minute. That cron job should be owned by root in order to be able to halt the computer. Then, to turn it on, I guess one could set the bios to turn on the computer automagically when the power gets down and then up again... Or one could use the computer power button (but in this case, it is an laptop that I want to hide deeply...) The whole idea behind this is to avoid to suddenly turn off the computer, which would probably corrupt the file system at some point. Of course I use GNU/Linux : probably Ubuntu Server or Debian.

Re: [PD] Turning on/off an installation
Hi Ben, Alexandre, I think Alex is worried about his file system.

[PD] To (re)set block~
The fact that [set new-size-as-a-power-of-2( | [block~] resets the block size seam not mentioned in the help patch (nor the manual). It might be obvious for some, though, i don't know. I had to guess how to use that inlet. Hence i'd like to suggest that this information gets added to the help patch. The question is, then, how to suggest it in the best manner? - by this email? - by altering the help patch and send it to Miller? - by altering the help patch and add it to the patch tracker? - by altering the help patch, 'diff -uw' and add that diff to the patch tracker? - by making a feature request in the tracker? - another way?

Re: [PD] gemmouse wish
Why not do [gemmouse 8 4] for 2:1 window? Of course you have to keep track of your own window size and alter the coords in responce, but that is largely the PD way anyhow, to keep track of what your doing yourself. You could just normalize from 0 to 1 and rescale based on your window size? As far as I know most platforms don't even allow mouse resizing of gemwindows... .b. marius schebella wrote: Hi, it would be very helpful to change the behaviour of gemmouse a little bit (to get similar results to the translation of objects in the gemwindow). [gemmouse 8] should normalize to the height (like gemwin) and not to the width. given a rectangular gemwin any aspect ratio (no difference between 2:1 and 1:2...) always normalizes to the height and sets (with the default view) the top and bottom borders to +4 and -4 gemmouse 8 on the other hand normalizes to the width. this makes it very difficult (unpossible?) to build mouse interaction with variable window sizes. another feature wish: to be able to tell the dimensions of the gemwin. esp. after resizing by mousedrawing. thanks, marius. ___ 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
