[PD] Simplest way for looping soudfiles

[Pagano, Patrick]

I would like it to be inside Pure Data without the use of externals.
I am quite aware of the externals, but I am curious on how people have done it without an external

:)

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

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.
