When you call fork(), the address space is duplicated, so unless there are already open files, the processes are completely independent. Re-entrancy, on the other hand, is hardly relevant. I guess what you really mean is thread safety. Unfortunately, libSoX uses some global state and is thus not completely thread-safe; even running two different chains in parallel in a single thread may lead to problems. However, if you a) use the same settings (buffer size etc.) for all chains, b) don't rely on the "subsystem" information in the message handler (either set verbosity to 0 or use a custom handler that doesn't read the subsystem value), c) don't mind a bit of extra randomness (read: race conditions) in the pseudo-random number generator, then it will probably work.
