What Òscar is suggesting also applies to [readsf~] and [tabplay~]. Both loop quite seamlessly when I've used them. the [open ( to [readsf~] doesn't seem to take any time. I haven't done the [readsf~] looping under heavy load tho.

Maybe I'm not getting anything related about this topic... but what about using the end "bang" that many audio-file-playing-externals feature?

Not Sure that one will not loop properly because of the need for an open message each time.
You are indeed right. It is not the proper way to do it. Even the help-file of [readsf~] states it. However, in practice it usually works flawlessly (probably nowadays disks seem fast enough and there is enough memory for fs caches). Simply try it with the help of [readsf~ ].
Also the table based approach works, though I'd make two modifications to the previously posted patch. Use the '-maxsize ' flag for the message to [soundfiler] in order to allow bigger tables. Then, I'd get rid of [tabread4~], as it is not needed when you only want to play at original speed. Actually, I even wouldn't use [tabread~ ], because for very large tables, the index from [phasor~ ] or [line~ ] will not be precise enough to hit every sample after position 16'000'000 (limit of the 32bit floating point format). If you use [tabplay~], it is as simple my previous example with [readsf~ ]:
[r playagain] | [tabplay yourpreviouslyfilledtable] | [s playagain]
IIRC, [tabplay~] doesn't suffer from that precision problem described before.
