I've written an external that does 3rd order hermite interpolation on it's input to write to a buffer~ to simulate the speed change of an analog recording medium {skipping buffer indexes and interpolating between them like the old dsp chips that pauline oliveros used to use for the expanded instrument system} - this works great

wondering if it's possible to read and write from an aiff within the same code without closing the file --- if it is possible is it feasible in terms of realtime processing?

sorry, newish to progamming - know max very well and c OK - but I don't really understand reading and writing to disk -

in greater detail, could one make c code that opens an existing aiff, and overdubs audio input ontop of it? {reading each sample and simply adding the audio input to the existing sample values, then close the file at some later point?)

path_opensysfile accepts the PATH_RW_PERM permission, so I suppose it is possible to read/write the same opened file.
