is there a way to access/playback sections of a file streaming from disk using this object or another one?

Readsf~

With [tabplay~] you can specify the start point, by sending a message with where you want to start in samples.

i think there is. i read about it a while back.
hang on...
-
excellent
- asking for a from-disk rather than from-array object or idea as I want to use it for a who song i.e. will probably be too big for an array
-
hmm...i was sure i read something about that a while back. but can't find anything, so maybe it was just a dream.
it might have been about sfread~ from zexy, which seems to have disappeared now.
very mysterious.

and not even one reply to this mail of andy's from last year.

i smell a conspiracy. someone is trying to keep us from accessing our soundfiles.
-
you can load whole songs into arrays though. add -maxsize 44100000
to allow a 1000 second file.
i just tried it here and it works ok.
-
(actually this is the first time i have ever loaded a whole song into an array, and my mind just went nuts.....lots of possibilities here)
(sorry for so many posts. today was payday so i'm drinking beer and being talkative)
still.... i wonder what happened to sfread~
-
ok, added a quick demo patch to my wiki.
-
Can't find the patch hardoff. Maybe i'm not looking hard enough

Got something that'll blow your mind... this goes all the way to the top, we're through the looking glass here people... Microsoft, in conjunction with the saucer people, under the supervision of the reverse vampires, in league with the Illuniminati....
Hold on there's somebody at the door....
Use the Source.

fixed the link. those damn terrorists must have got in and altered my code

I am using readsf~ with my Pd 0.39.3, and it works fine without an problem.. Here is the patch..
-
Cheers tcihan, I've used readsf~ before, but what I really need is something that will allow me to select a section of the file from disk and play it back e.g. 3000 to 8000 ms of a 60000 ms file, change speed, re-select a different section etc. Also to not have to re-specify the file after each playback would be great.
Hardoff - the end result of this search is to come up with a DJ type patch which allows the pre-loading (selecting) of lots of different tracks. Your patch works great but I'm wondering what the ceiling is for CPU use and how it will effect load time into the array, obviously if this pauses mid set it could be quite embarrassing.
Maybe it's time I took the leap and wrote my first object...
-
there is an upsampling trick for loading sound into arrays without clicks. i never actually tried it myself, but it seems definitely possible. some people on the mailing list reported 64x upsampling working ok.
i have asked there for a patch, but maybe someone here already knows how it works?
-
well, roman recommends putting a [readsf~] and a [tabwrite~] in a subpatch, and then adding [block~ 1 1 64] to read at 64X speed.
then iohannes said that [block~ 1024 1 64] would be better.
my computer's a bit slow, so i could only load at 16X without getting dropouts.
also, you have to have at least the filename of your soundfile stored in your patch, because using [openpanel] while audio is running will lead to dropouts too.
-
oh, and here is the help patch for readsf~ i have on my linux machine. apparently you CAN set an offset.
my version of pd-extended on os x has an older help patch which doesn't mention that.
