Re: [Pdmtl] [PD] 24 bit causing distortion

In PureData, all mixing is done using 32-bit floats, which are like 24-bit integers, plus adaptive resolution, so that the effective number of bits stays 24 no matter what's the dB. So that's a lot more headroom than anything you can get with 24-bit integers. That kind of resolution is mostly only useful during processing. The 24-bit integers would only be for recording to .wav. Honestly I don't really know what's the fuss about 24-bit recordings. Maybe because some company got pushed into higher-end equipment than what was ever desired, so they created the desire and thus the market. Each bit of resolution requires 6 more dB of S/N ratio in order to not get masked by the hiss. Multiply that by just 16 and try to find me a soundcard with a S/N ratio of 2^16 = 65536 = 96.3 dB (!!!). And then fetch me an ear with 96.3 dB of S/N. BTW, one can cheat by recording at a very, very quiet level, and then playing that real loud. This allows your salesman and/or brother-in-law to effectively disable the top bits of your 16-bit range, making the 24-bit recording of the same thing sound so much better. I must add that if you mix a lot of tracks together then the result still has to go through the same file, soundcard, loudspeakers, room and ears than before, and if there are 8 simultaneous sounds playing in the same frequency band with equal loudness then they compete for the available amplitude range in a way that each of them needs 3 _less_ bits in their pre-mixing recordings. The float stuff of Pd is more useful than that because Pd's DSP is used for more than just sound: e.g. it is also used for indexing into recorded sounds, and that needs a lot more resolution (and, in fact, many would say float32 is not enough for that purpose).

hi list and Yves you were right: i needed to add that path to my ld.so.conf. Thanx :) but now pd claims: usr/lib/pd/externs/pidip.pd_linux: undefined symbol: mp3lame_encoder why that? shouldnt all that mp3lame juice be squeezed, when ffmpeg was compiled? many thanx in advance daniel . ----- Original Message ----- From: "Yves Degoyon" <ydegoyon(a)free.fr> To: "daniel kosenko" <zvuk(a)linuxmail.org> Subject: Re: [PD] pidip-0.12.19 doesnt load Date: Thu, 11 Aug 2005 23:23:29 +0200 > > ola, > > maybe you only need a "ldconfig -v" > or /usr/local/lib is not in your libraries' search path ? > > suerte, > sevy > > daniel kosenko wrote: > > > hi list > > > > Cant figure out why pidip doesnt load.

Reminder: Piksel05 - Call for entries
by 220hex 12 Aug '05

12 Aug '05

+++ only 3 days left... +++ ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| -- Piksel05 - october 16-23. 2005 -- call for participation -- deadline 15. august 2005 ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Piksel[1] is an annual event for artists and developers working with open source audiovisual software tools. Part workshop, part festival, it is organised in Bergen, Norway, by the Bergen Centre for Electronic Arts (BEK) [2] and involves participants from more than a dozen countries exchanging ideas, coding, presenting art and software projects, doing workshops, performances and discussions on the aesthetics and politics of open source. Piksel05 will take place in Bergen october 16. - 23. 2005. The development, and therefore use, of digital technology today is mainly controlled by multinational corporations. Despite the prospects of technology expanding the means of artistic expression, the commercial demands of the software industries severely limit them instead. Piksel is focusing on the open source movement as a strategy for regaining artistic control of the technology, but also a means to bring attention to the close connections between art, politics, technology and economy. One of the results of the past Piksel events is the initiation of the Piksel Video Framework for 'interoperability between various free software applications dealing with video manipulation techniques'[3]. Piksel05 will also feature the release of the Piksel LiveCD[4], a Linux distribution containing the software used and developed at Piksel. The package contains a suite of innovative audiovisual and artistic software, free video plugins, and documentation from the past Piksel events. |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| open CALL for PARTICIPATION The last two Piksel events has focused on live art/audiovisual performance, but for Piksel05 the main focus will be an exhibition in collaboration with Hordaland Kunstsenter[5]. For the exhibition and other parts of the program we are interested in submissions in the following categories: 1. Installations and interactive work Audiovisual installations created and run solely using open source software. The theme for the exhibition will be loosely related to 'games' and the gaming experience. 2. Audiovisual performance Live art realised by the use of open source software. 3. Software Innovative artistic tools or software art released under an open licence. Please send documentation material - preferably as a URL to online documentation with images/video to piksel05(a)bek.no Deadline - august 15. 2005 Use this form for submitting (or go to the online form at http://www.piksel.no/piksel05/subform.html): |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 1. Name of artist(s), email adr. 2. Short bio/CV 3. Category 4. URL to online documentation 5. Short statement about the work(s) 6. List of software used in the creation/presentation of the work(s) |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Or send by snailmail to: BEK att: Gisle Froysland C.

hi there, is there any way to zoom into a texture in gem? That is, before it is textured onto a geo? There is an (experimental) object pix_zoom, but it doesn't seem to do anything ... thanks in advance, thoralf. ___________________________________________________________ Yahoo!

Hi there, sorry for asking such a dumb question, but as a compiler newbe, I lost my nerves trying to compile Flext + MSD. First to the Flext. I set up bcc (from Borland) but it gives the following errors when trying build-bcc.bat: unable to open include file package.txt Name variable must be defined I adapted the config-win-pd-bcc.txt but anyhow it doesn't work - any ideas? Could anyone be so kind to help me out - am I missing a file? Thanx a lot, Enkidu Enkidu @ www.Einheit7.de/Personal/Enkidu Mr.&Mrs.T's Music @ www.Einheit7.de/Mr-T I.A.T.W.I.A.T.I.A.

I did exactly what INSTALL says and got no errors while compiling (checked if mp3lame is enabled). pd says: usr/lib/pd/externs/pidip.pd_linux: libmp3lame.so.0: cannot open shared object file: No such file or directory. Checked: its here /usr/local/lib/libmp3lame.so.0 I`ve got: pidip-0.12.19 pd-0.38.4 ffmpeg-cvs-2005-02-08 on demudi-1.2.1 many thanx in advance daniel

Movable Objects (help!)
by Carl Najafi 11 Aug '05

11 Aug '05

Hello all, I'm a new list member so I will introduce myself briefly before my big question. My name is Carl Najafi, I'm 23 years old, have been working (-not as in making money from it-) with sound in various ways for a couple of years now, recently aborted my fine art studies to give my composition more time. Ok, as I'm a relative new PD-user (well, actually very new, with about 3 weeks of experience) I'd like some advice with a patch that may be very simple, its just that I can't really get my head around it. I want to have two (or more) movable graphical objects (like boxes) i one window. The coordinates acts as freq/mod/etc. With one object (or atom I think it's called?) there's no problem, but I think it has to do with the x and y - you're not supposed to have two x and y's right? Anyway, I'd like to know how to replace one or the other x or y to make my life a bit more simple (the patch now has 3 windows which makes it hell to do something useful with it...). Well, thanks in advance... Carl Najafi

Motorized faders as force feedback?
by Spencer Russell 11 Aug '05

11 Aug '05

So I'm waiting for the Behringer BCF-2000 control surface that I bought off ebay, and thinking of all the fun stuff I could do with it. There's a PMPD example patch with several sliders connected to eachother like an elastic string, and I was thinking it'd be fun to connect each slider to a fader on the BCF, so when I moved one fader, the others would move in a ripply wave effect. That got me thinking of other fun ways to use the motorized faders, and as I've also been thinking of getting a force-feedback controller or 2, I was wondering if it's damaging to the motors or anything to use them for that. I've never really used motorized faders for anything besides recalling sessions on digital mixing boards, so I don't really know how they react to the resistance of your fingers, and if they can push against you without doing any harm. any thoughts? -spencer

pidip_ascii
by Ed Kelly 11 Aug '05

11 Aug '05

Hi, I got pidip working the other day and ran the pdp_ascii help file. How does Yves manage to get Arabic as his ascii font? I just got regular (English) ascii. Do you have to set up the computer as Arabic?
