I myself used to use alsaplayer a lot, but, to be honest, it pretty
often segfaulted.

So, it's not only security, though both might be related to buffer
overflows.

To me support of alsaplayer seems like too much unpleasant work to an
unrelated person.

By the way, isn't pitch control and speed control in this context the
same ?

You can't play faster than the input stream, because you do not yet know
what's in the stream.

And if you play slower, you need ever growing input buffer.

Because I thought speed control and pitch control were the same in this
context I gave the link to http://sculptor.sourceforge.net/sculptor.shtml .
