[PD] readsf~ problem with 28-channel 256hz file
Hi, I'm trying to play back a rather uncommon file with readsf~. It's 3 hours of EEG data, on 28 channels, with a samplerate of only 256 hz. At first sight, readsf~ deals well with the 28 channels, but it seems to play it back way too fast.. Is there a way to make rit play back the file at the right speed? I'm using Pd version 0.40.3-extended on windows xp.. thanks!

[PD] looking for peak/notch pair
Hi,I need a pair com truly complementary peak/notch filters in pd, such that cascading them is guaranteed to provide a flat magnitude response. Does anyone know whether there is a suitable filter pair for that in pd or pd extended? Any 2nd order filter with adjustable center freq. would do. Having the sources available would help as I need to test them outside too.Thanks in advance!Josep ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] readsf~ problem with 28-channel 256hz file
If you only want to playback the data, then the easiest way might be just to change pd's sample rate to 256hz. If that doesn't work, maybe have a look at readsf~ help to see how to manually set playback parameters On Tuesday, August 7, 2012, kristof lauwers wrote: Hi, I'm trying to play back a rather uncommon file with readsf~.

If you have enough ram, you could also load all soundfile data into 28 tables, and read from those using tabread4~ or even a message-based tabread followed by a line~. i will give that a try. thanks for the suggestion! greetings, Kristof On Tuesday, August 7, 2012, kristof lauwers wrote: Hi, I'm trying to play back a rather uncommon file with readsf~.

Have you tried opening the 256Hz wav file(s) in another application, such as sox[1], and resampling it there, resulting in a 44.1kHz file? just an idea best, Jo [1] http://sox.sourceforge.net/sox.html greetings, Kristof On Tuesday, August 7, 2012, kristof lauwers wrote: Hi, I'm trying to play back a rather uncommon file with readsf~.

[PD] playing videos with sound /Gem ?
Hi list, we are making an exercise in Gem where is needed to play a video with its sound. tried [pix_movie] and [pix_film] but in those is not possible to extract signal connections. Other objects or libraries in Gem that makes this possible? [Already tried also pdp2gem and the lib Audiovideo (http://www.uni-weimar.de/medien/wiki/Audiovideo), but no success in both (not audio in first / and many crashes in second)] suggestions? thanx xm. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Other objects or libraries in Gem that makes this possible? [Already tried also pdp2gem and the lib Audiovideo (http://www.uni-weimar.de/medien/wiki/Audiovideo), but no success in both (not audio in first / and many crashes in second)] the Audiovideo patches are meant to explain different techniques how to play back audio and video in sync. It is a often reoccurring question on this list, so I made those patches. It is not a library, just patches. If you experienced crashes - this may happen if you load very long videos in the gem framebuffer, which is only meant for short sequences. If your graphics card has not enough memory that may happen. please be a bit more specific if you want more specific help - that is in the problem description as well as in the bug report. m. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] [PD-dev] Flext compiled objects in Pd 0.43.1 (fluid~ py/pyext)
Hi Glerm, i would be interested on the circumstances why pyext doesn't load. Are you sure that you used a valid python script (to be found in the current patcher directory or the pd path?

Some could say I should had separated the 2 objects issues in different threads for this mailinglist, but since I think most of pd(extended) users don't even try to compile flext objects I think this is the best subject title for now... so the question is: who already could run some of those 2 objects at Pd 0.43.1 and if maybe it's some with flext compilation problem? or whatever, some tip about one of those objects? thanx glerm ___ Pd-dev mailing list pd-...@iem.at http://lists.puredata.info/listinfo/pd-dev -- Thomas Grill http://g.org +43 699 19715543 ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
