All,
I'm working on a patch that will be a multitrack audio player - it needs to play 8-16 tracks of audio concurrantly, each track from an audio file of some undetermined length.
I would like to stream the tracks from the disk without loading them into memory, since to do so will both take a lot of memory space and cause delays when queuing up new tracks.
Does anyone know of a PD external/object that would accomplish this? sfread~ looks decent, but I suspect it loads the file to memory. Or does it in fact stream?
Any help is appreciated.

sfread~ should do the trick. AFAIK it streams, since it's recording counterpart sfwrite~ is designed to stream a recording to disk.
To be sure, you could try some system monitor to tell you how much RAM is being used. What OS are you running? With a *nix type system, you could try "top" to see memory usage, and check how much PD uses before and after using each object. There are also graphical monitors such as Gkrellm2 under Linux.
sfplay~, in Zexy, might also be worth a look, although I can't tell you the exact difference between this and sfread~.
Last but not least, there is August Black's readanysf~ external.
good luck, d.

And don't forget the built-in readsf~ which is what I would use.
