Use a temporary stack buffer to store the source buffer data to be mixed
...
This makes it much easier to pack the playable buffer data so that it's a
continuous data stream. This could normally be broken up otherwise, such as
when using loop points or small queued buffers.
Currently it defaults to a 16KB stack buffer, but this can be overridden at
compile time.
