Sigmund~ or Bonk~ question: discerning input between two sounds
by Sebastian Valenzuela 08 Nov '11

08 Nov '11

Hi everyone, I'll be beat-boxing (with my voice) TWO sounds into my computer microphone: a "Kick drum" sound and a "Hi-Hat" sound. I would like to use some sort of spectral analysis object to send bangs when it recognizes them. I ran these two sounds through a spectral analyser and found that the "Kick" sound was between 100-300 hz and the "Hi-Hat" sound was between 1k-10k hz. What is the most precise way to do this? In [sigmund~], what are the arguments I would use, and how would I specify these ranges through these arguments? Thank you for your time, Sebastian

[PD-Graz] PD-Patching Circle in Graz, November 22nd
by Peter Venus 08 Nov '11

08 Nov '11

Dear All! we thought, it is about time to re-start a series of monthly patching circles in Graz again. The idea is simple: Get together to discuss problems, share and work on tasks and patches with PD. Of course, users of related software are also welcome- so if you are more into SuperCollider, Processing etc- don´t hesitate to come. Every patching circle will also be featuring a short presentation of some external, abstractions or similar. For the first meeting, we invited Matthias Kronlachner to present the Kinect-External [pix_freenect] he made. ( http://matthiaskronlachner.com/?p=299 ) The patching-circle will be held on November 22nd, 19°° at ESC im Labor, 2nd Floor (aka CC) Jakoministr. 16, 8010 Graz cheers, Peter

Re: [PD] Interruption of audio / Loading sound into array
by Sebastian Hanusa 08 Nov '11

08 Nov '11

Dear pd-people! Thank you very much for the help concerning my problem with loading sounds into arrays. In my practice the solution with [tabwrite] and [readsf] in combination with a table instead of an array works very well. Best regards, Sebastian

symbol2list leading zero
by rolf meesters 08 Nov '11

08 Nov '11

hi, i'm using [symbol2list -] | | [symbol( | | | [list2symbol] on something like 00-ab-87-02. the result becomes 0ab872. so, i'm losing the leading zero's. in other words the symbol '00' is handled like a number, probably any symbol that looks like a number is immediately treated like that. which, in the case above is unexpected (at least for me). would it then be necessary, working with texts, always to check if one's not accidentally losing zero's? rolf

communication from Shahrokh Yadegari about expr rewrite
by i go bananas 08 Nov '11

08 Nov '11

Dear Matt, Thank you for your email. Re-writing expr with BSD license has been on my mind for a while and I would like to do it. I do not need to be paid, but I like the idea of collecting money for donation to a non-profit organization that could help cultivate computer music, specially one that uses free software. So, your pledges would motivate me more. Do you (or Miller) know of such a fund/scholarship? I cannot promise you when this will happen, but I will make it a high priority item on my work list. Please feel free to share this email with the list. best, Shahrokh

which is the more reliable object to load a gif?
by Marco Donnarumma 08 Nov '11

08 Nov '11

Hi all, it drives me nuts and it's not even an interesting issue. I'm using the [image] obj from moonlib. Works good on Linux, but I'm teaching workshop in which students may be using OSX. On some OSX machines it loads properly the images, on others it loads one image but not the others (they are all gif imgs in the same folder), or it only properly loads an image after manually send an [open something( message. I think it might be related to folders permission, but the issue is different on each single osx machine and I don't have a mac to debug. I tried also [iem_image] but I had the same kind of instability on OSX. I usually create the [image], open a file and save. Works on Linux. Adding a [loadbang] does not help. Is there some tricks or something I'm missing so to use it properly? or which is the most reliable and cross-compatible way to display an image in Pd? thx, -- Marco Donnarumma Independent New Media and Sonic Arts Practitioner, Performer, Teacher ACE, Sound Design MSc by Research (ongoing) The University of Edinburgh, UK ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Portfolio: http://marcodonnarumma.com Research: http://res.marcodonnarumma.com | http://www.thesaddj.com | http://www.flxer.net Director: http://www.liveperformersmeeting.net

I think they are also listed in the changelog under a specific date which should make things a bit easier to isolate. That said, implementation alters widgetbehavior struct by adding one more entry and as such it breaks compatibility with gridflow unless recompiled from scratch using the new .h file. Even then there might be other incompatibilities. That said, I've encountered none, other than gridflow. Of course, other externals need to be recompiled as well (but no changes to their source are required).
