hello all, is there a way to use tabwrite~ for a circular buffer?
in other words, is there a way to make tabwrite~ go around and start recording in the beginning of the table, once it has reached the end?
i have done some searching and found this thread: https://forum.pdpatchrepo.info/topic/8260/creating-a-live-input-circular-buf...
but there seem to be no resolution; i realize that you can do this with a different method of writing into tables that's driven by events, but i'd like to do it with tabwrite~ and all signals.
thanks!

Here's what I do (probably not the only way but it works): if you want the most recent 10 seconds of input available in a contiguous stretch in an array, make an array big enough to hold 20 seconds, and using two tabwrite~ objects, alternatively bang one or the other every 10 seconds. At any moment the stretch of the array between the two tabwrite~ pointers (which you can find using "timer") is 10 seconds long and contains the most recent input samples.

What about using delay lines Ali? Those are circular buffers...

Funny incident as i was searching for this today as well. I indeed used a delay line in combinatin with tabsend~ and a banged switch~ to be able to have an up to date table of 8192points every 40ms at a samlingrate of 44.1k. Hope this gives any clues, esle i could give an example tomorrow.
Best,
Johnny
