lookin' for an object…

June 3, 2006 | 6:37 pm

hello there ones again..
i want to connect a turntable ,playing a simple sine sound ( i will try to upload a sample of it soon), in the line in of my pc get the sound through a max patch which gonna understand if the turntable plays the sine sound normal or reversed…
can anybody suggest me where to start or have in mind any object NOT in the standar library of the max/msp??
thnx to y alll

explain a little more if you could…

a sine wave will be identical forwards or backwards

ms pinky is what you need. it’s saw that you need, plus a pulse comes in handy for timing…
it’s pretty cheap, will probably get it myself.

i know about ms pinky
but i am trying to do something different
and i need a patch to recognise if the sound goes forwards or backwards


June 4, 2006 | 9:05 pm

that is typically what *timecode* is for.

just as mr. frit said:
you won’t be very lucky using a sine ;o)

lets say i am using a saw..
a saw will more easy because the backward is very different from the forward..
what about that…
is there any timecode records cheaper than ms pinky??

First of all: please find a better title for your email. Something that
defines the issue you want to talk about. Per example: "detect
forward/backward sounds".

Imagine the mess in the list archive: only posts named like this: "please
help", "newbie questions", "can someone help me?", "I’m looking for an
object.", etc…..

Does the sound you want to analyse comes from [adc~] or from a [sfplay~]
or [groove~]?
If it’s from a sfplay~, just use the speed parameter (if it’s below zero,
it’s backward) or track the current position output (in ms): if it’s
incrementing, obviously it’s forward….

If it comes from adc~, I don’t think there’s a way to detect a reversed
sound, unless you can compare it with another sample of itself.

Good luck!

First read the first post in the thread before you boss others on how
to post…

howeso different? seems you want to do exactly what it does.
the saw would work.

That one got to me privately although it’s not really adressed at me.

BTW = by the way

odd – that post has no content on the forum, but showed up in the loadbang email

At this point it might be useful if someone could post a URI for one
of the many lists of widely-used abbreviations (LOL, IMHO, TMTOWTDI,
ETCETERAETCETERA…)

That could even be a sticky.

Having said that, the "The Smart Way to Ask Questions" document would
be another good thing to stickify (with a URI pointing to the document).

There are some other sticky candidates, and there is the argument
"too many stickies and no one will read any of them." So I wonder
aloud at this point if it might be a good idea to have a couple of
messages that get cycled through as stickies, maybe for 48 hours
before replacing it with the next one. 3-5 items of that sort would
(in theory) be seen once a week (or so) by everyone.

Just an idea made without regard for technical feasibility. Any
response on the idea, Wally?

Finally,

I did not read the suggestion on more appropriate subject lines as
"bossing others around" (authoritarianism does not typically make use
of the verb "please") but rather as a statement of fact. "Lookin’ for
an object" is *not* a descriptive subject line. *Everybody’s* looking
for an object, most of us spend a great deal of our lives looking for
yet another object. If I sold a software license every time someone
on the list was looking for an object I could < activity requiring obscene amounts of wealth here>>.

Patrice’s suggested alternative was actually a pretty good one and
was hopefully received with good grace by the addressee.
