[erlang-questions] Building a DAW in Erlang

Hi,

So, great ignorance speculating here, if we can generate basic wave forms with Erlang terms then, next, we need to be able to edit, mix, amplify, attenuate, play with phase relationships, etc., etc.

My superficial Google search didn't come up with much. This exchange touches on the issues:

But it does feel like a vast field for bottom-up play. Shame that there are so few hours in the day.

All the best,

Lloyd

Since the external term encoding of a binary includes the bytes of
that binary verbatim, yes, yes, and yes.
