Pick up sfront 0.58 04/17/00 from:
http://www.cs.berkeley.edu/~lazzaro/sa/
Change log message:
[1] The control driver
API has been improved.
It can now support
compliant execution of
MP4 SA_access_units,
as well as patch editor,
CLI, and symbolic debug
applications. It
includes many data
structures that let
the control driver
discover information
about the SAOL and SASL
files used to generate
the sa.c it lives in.
[2] The programers
manual for sfront has
been reworked, and now
includes an introductory
section that explains
how to use sfront from
other programs, and a
multi-part manual
on the control driver
interface. See:
http://www.cs.berkeley.edu/~lazzaro/sa/sfman/index.html
[3] A file streaming
control driver has
been written to
demonstrate the new
API. It opens an MP4
file during the start
of sa.c execution,
seeks past the config
section, and then
dynamically executes
SA_access_unit stream
packets. It contains
much of the codebase
needed for true
MP4-SA network streamer.
[4] The spline wavetable
generator was described
incorrectly in the MP4-SA
book, and implemented
incorrectly in sfront.
Both book and program
are now fixed. See this
book section for the
correct syntax (page down
to the spline generator).
[5] SAOL random opcodes
now produce a different
random number stream on
each sa.c run. New
-fixedseed sfront option
simplifies SAOL program
testing, by making all
random opcodes produce a
deterministic number stream
on every sa.c run.
Thanks to Martin Marier and
Michael McGonagle.
[6] Many bugs were
fixed. Most bugs were
in SASL and SAOL wave
table generator code,
and in the control
driver code. Bugs were
also fixed in the
linmidi driver.
