[PD-announce] lib adaptive FIR filter
by noisternig＠iem.at 02 Aug '06

02 Aug '06

hi all, recently, we wrote several external objects doing FIR adaptive filtering with coefficient constraints by (normalized) least mean squares algorithms (N-LMS). you'll find them ready to compile plus help files at CVS under /externals/iem/iem_adaptfilt please see the ./doc for further help on the algorithms! i hope to be able to provide faster algorithms like RLS or APA soon? maybe this helps with feedback problems too :) cheers markus _______________________________________________ PD-announce mailing list PD-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Thanks for your reply it was really helpful but, I have just a couple more questions > You don't need to know much about the length other than > to make sure the array will fit all your sound into it. As long as I have enough length specified (I just use the soundfiler output) It works fine for one-shot playback. But if I need to loop a sample sometimes I get a click, thats why I thought the length of the array had to be precise and that I need to put guard points in the array? > If you change the size of the array it depends what you > want to do, play the sound in the same time, or with the > same pitch. In the latter case keeping the *rate* of the > line constant is what you need to do. I dont fully understand how to do this. I want to use tabread4~ in conjunction with other objects in one case to change the speed and keep the sample at the same pitch and in another case to just change the pitch and keep the sound length the same. Is there a way to do this?

I tried the implementation with the [select] object and I put and extra select to be sure that the counter never exceeds the maximum of 8 steps. Attached you'll find my current 8step implementation. --------------------------------- ΓΓ±Γ§Γ³Γ©Γ¬Γ―Γ°Γ―Γ©Γ₯ΓΓ΄Γ₯ Yahoo!

The [tabread4~] object is an interpolating reader, it takes 4 points in the table and smoothes out the signal by using all 4 instead of just one point to calculate the output value. I forget whether the -2 is related to that in Pd or not. You don't need to know much about the length other than to make sure the array will fit all your sound into it. The array might contain any number of points. What matters is the rate at which you read them out of the table and so to the DAC. That [soundfiler] gives you the file length is a nice blessing. What you use to index the table is what matters, for example a [vline~] where you give a start, end and time will always complete it's line segment in the same time, even if you alter the length. > 2.Again regarding the length, taking the example B07.sampler.pd, what happens if the length of the sound > file changes? Do I need to change the value I am multiplying by or is that dependant on the sampling rate of the audio file? If the sound file changes on disk you need to reload it, but I realise that's not your question. If you change the size of the array it depends what you want to do, play the sound in the same time, or with the same pitch. In the latter case keeping the *rate* of the line constant is what you need to do.

Pd dual metro ..
by Tas Pas 02 Aug '06

Hi list, I'm trying to built an 8step sequencer and I'm using configuration with 2 [metro] objects. One to count the steps and another one (with a [metro]#1 interval x number of steps interval) to reset the steps number. It works fine, but, when I set the steps to 1, istead of getting a 1 value to the counter, I get 2. I attached the pd file just in case I didn't succeed in making you undestand. Cheers. --------------------------------- ΓΓ±Γ§Γ³Γ©Γ¬Γ―Γ°Γ―Γ©Γ₯ΓΓ΄Γ₯ Yahoo! ΓΓ‘Γ±Γ₯Γ¨ΓΓͺΓ‘Γ΄Γ₯ Γ΄Γ‘ Γ₯ΓΓ―Γ·Γ«Γ§Γ΄Γ©ΓͺΓ Γ¬Γ§ΓΓ½ Γ¬Γ‘Γ΄Γ‘ (spam); ΓΓ― Yahoo!

readanysf~ any success?
by mart ameise 02 Aug '06

02 Aug '06

Hello you all, does anyone uses the [stop] message with readanysf~ ? i saw several posts on the list, that there is a bug or something (at least on my debian unstable, pd-0.39.2,flext 0.5.0, latest readanysf~, it crashes while freeing some ressources...with vorbis library it segfaults..) is there any combination (maybe precompiled linux pd-extended binaries) that work? or is there any other object doing the same stuff? i think, someone have asked all this before: so sorry for that... greetings mart

More GOP fun; arrangement device
by Chris McCormick 02 Aug '06

02 Aug '06

Hi, I hope people don't mind me posting these abstractions to the list with such frequency. It won't continue for much longer once I start work again. This one is a general song or sequence arrangement tool inspired by Frank B's "blocks" datastructures example. You can drag blocks and change their length and use them to represent sections of your tune/trigger samples/whatever you like. I made it because all my music so far in Pd is jammed out live, and lacking in structure. http://mccormick.cx/viewcvs/*checkout*/s-abstractions/s-arranger.pd http://mccormick.cx/viewcvs/*checkout*/s-abstractions/s-arranger-help.pd Oh yeah, it saves all blocks in-patch, or in-file using Frank's sssad system. You may write German techno, or hip hop instead, at your option. Enjoy! Late for beer o'clock, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx
