Hi Everyone,
I've been having problems for a while with almost all of the external libraries not loading in Pd-extended. I have tried a couple of times to fix it but have not had success. I've read a couple of the other threads on this topic and i think maybe it is a problem with the org.puredata.pd.default.plist but i dont really know what is wrong.

here is what is in that file:

I'm trying to use pix_movie and pix_film to try out video playback in GEM, but every time I do it I get an error saying it can't decode the video. I've tried a couple different formats, and none have worked (one said there was no quicktime support, the other said it couldn't decode MPEG3). Any suggestions?

(I'm running on Debian Etch, btw.)

Thanks.

there are two issues that fight to such an extent they are exclusive afaics, you can have good absolute time encoding so that you can drop anywhere into the timecode and quickly know the position within something like an hour of audio, or you can can have good relative encoding such that you can scratch the actual audio back and forth.

Old frame based timecode such as used on tape, I can say from experience is no use to scratch, it takes too long for the decoder to lock to the absolute position and the divisions between time markers is too big. You can get the decoder to interpolate (or freewheel) between marks but without enough marks per second of code it won't work for scratching.

Sounds like Pinkys system is using FSK, which uses two sine tones like a modem, the trellis encoding is an ECC layer that makes this more reliable and a little more efficient, but basically this is how you encode a binary number into vinyl to tape (if the groove actually had 1s and 0s it would break the stylus very quickly)

If we started at 0 and had one second of codes at 44.1Kz then
at 33 rpm (0.55555 revolutions per second) at 12 inches (30cm) diameter
gives us 1.885m/s (at the best case outside of the disc), which is
0.0000427m for each timecode chunk. In that chunk we would have to
encode at least 24 bits to have an integer time index over about
an hour, making the distance between timecode chunks 1.7e-6m.

Too small!

That's why we have CD technology not not vinyl, if there were a
way to squeeze that much digital info into a vinyl groove Phillips
or Sony would have looked at it

If we use an entirely relative approach, where instead of symbols we encode a constantly
variable analogue signal (what vinyl is best for) and use that to increment or decrement a
counter in the decoder much better results are possible.

Some timecode is reversible, that's kind of the point when you work with tape, you have a buffer and a way to detect frame boundaries and read the frames in reverse.

> Any other Ideas?

Personally I believe the best way is not to encode on the vinyl at all, but to make a turntable
that very accurately measures the angular velocity of the wheel and the angular position
of the tone arm pickup. You can probably do this using bits hacked from a disk drive. It would need
occasional calibrating, but is the best all round solution for high resolution with absolute time. (think of the tone arm and the table rotation like the mantissa and exponent of a floating point number, they're both part of the same number with the tone arm counting the big divisions and the turntable wheel counting the smaller ones.)

I'm trying to make a free alternative to the decoder found here: decoder - It is too expensive for me and for a lot of other people, I think. I'm not trying to put them out of business, but to make an alternative for people who are willing to mess around with electronics and who can't afford a readymade decoder and glasses.

for 2: I have already had a look at the fiddle~ and bonk~ externs. They look promising, but I don't understand them well enough to actually use them.
The audio contains other sounds + the 19,2 KHz signal, so I guess the envelope follower is out.
I hadn't thought about filtering the signal, as you suggest. Maybe I can use that in conjunction with fiddle~ ?!

hi
haven't registered any sooner to this forum...

however, we at the IEM are doing a lot of stuff with ambisonics and pd.
basically, my thesis has been a generic ambisonic encoder/decoder for any number of input/output channels (one of our settings is, e.g., 24 channel input decoding to 3rd order 3D-ambisonics onto a 24 speaker hemisphere - but that was done back in 2001)

see if i can find the patches (if you are still interested)
i used to build debian-packages for this (but never made it to release them)

Sorry for the missing explanation ...

Ambisonic is a spatial sound reproduction technology which have been introduced in the 70s by the mathematician Gerzon. With Ambi the loudspeaker layout may be anything from few to many loudspeaker and it is intended to reproduce the direction of arrival.

You first encode your target sound field .... its like Fourier Transforms but in space! You can do it with a virtually defined sound field in your computer or you can encode real sound field using a set of microphones (omni + figure-8) correctly placed in space. Once you got the transformed version of your desired sound field ... you decode it using your loudspeaker layout. Decoding is matching your encoded sound field with your sound reproduction system.

For basic encoding/deconding ambisonic (there is some more advanced encoding/deconding rules) you compute everything with matrix. Thats quite faster and more efficient than computing every elements individually.

My ambisonic patch (which is not finished) use such matrix computation although is not really pure-data clean (with some sort of very fast "for" loop made with metro objects!) ...

Anyway I still have some doubts on my equations ...

For this reason, I would like to compare my patch with some other ambisonic work for PD. There is a complete paper on Ambisonic with CSound in Computer Music Journal, winter 2001 ...

Bye!
