acquire-signal

i would like translate the flux of a signal in max value in reel time i use the snapshot~ object with 1 like argument.Have you a better solution??

hi,
i would like translate the flux of a signal in max value in reel time i use the snapshot~ object with 1 like argument.Have you a better solution??
thanks


this is the explanation of my problem in max language.Thanks for all .

faster than snapshot 1 ms and in realtime - no.

As you keep the word transcription, which you think is something 

everybody should know (but doesn't), its not explaining more of your 

If you tell us what you want to do with a "transcribed" value, it might 

If you feed the snapshot~ with an audible signal (sound or music) and 

you expect a random value between the +- of the peak value, then 

snapshot~ is what you want. I don't know for what this should be good 

though, I guess you expect something else...

Just some guesses: You want the average of the value, or you want the 

level of the signal (average of the absolute value) or you want some 

snapshot~ 1 in general is not a very good idea, it eats cycles like a 

Tyrannosaurus Rex would eat young musicians...

i have a bad english and i have difficulty to explain my problem.

i use ms pinky vinyles which are vinyles just send a signal.1 when normal playing -1 when reverse playing. But with scratch techniques the signal change everytime. I want scale the variation of this audio signal in max value in realtime,that's why i use the snapshot~ object.But maybe there is a less expensive way for the Cpu??

thanks for your advanced answer stephan.

In principle there is nothing wrong with snapshot~, but if you snap it 

every millisecond you create a lot of data for the scheduler and it 

might not be able to follow. Just do not use it faster than you would be 

able to follow with your own human reactions. Maybe 10 ms or 50 ms, 

depending on the intended use might be already appropriate.

If you just want to grab the switch, look at edge~ it will only output a 

bang when there is a change from 0 to 1 or 1 to 0, maybe in combination 

with change~, the helpfiles for these objects should get you going.

acquire signal??
