Subject[Cs-dev] Time for an assessment
Csound5 seems to have made great strides of late (thanks Istvan and
the rest) and it seems time to think of where we are.

The To-do-and-fix-file is a little out of date but..

KNOWN AREAS OF INCOMPLETENESS
-----------------------------

K1.	There is no looping structures for aiff (or wav) files

K2.	Parser

K3.     Portaudio.v19 on OSX

K4.     Use of PortMIDI
        Seems working -- needs checking

K6.     Installer for Linux

K7.     Installer for MacOSX

K9.     Scaling of floating files not clear

K10.    Dnoise not changed to libsndfile


BUGS NOT FIXED
--------------

B1.     Loading of deferred files in gen1 suspect

B2.     Many differences between FL code on Csound and CsoundAV

B3.     If no output format given does not have a sane default.


Anyone care to correct this?

It seems like it was a year back that I last did this -- I can not
really believe that! -- but..

This is only possible with the latest version of libsndfile (1.0.11);
should not be very difficult to implement, but it may be worth waiting
for another release of libsndfile so that we can see if the new loop
interface is stable, and users have enough time to upgrade from older
versions of libsndfile.
Perhaps the loop code could be enabled with #ifdef's.

> K10.    Dnoise not changed to libsndfile

It was actually changed to use libsndfile, and seems to work.
The following utilities do not work, however (and currently are not
event built):
   hetro
   lpanal
   mixer
   scale
   extractor (for sound files)
   *_export
   cscore
   scot
   sdif2ad
additionally, pvanal only supports the old PV format, but not PVOC-EX.
The SDIF and PVOC systems need to be correctly integrated with the API,
preferably with some help from the author(s), for hetro and pvanal to be
fully functional again.
These utilities work, and have been converted to plugin libraries (with
changes for re-entrance, use API, removed statics, printf(), exit(), etc.):
   cvanal
   dnoise
   pvanal (old format only, no graphs)
   pvlook
   sndinfo
   srconv

More details about these ?

Fortunately there is rtcoreaudio.c.

What major change is needed ?

>>> j) MIDI

A native driver may need to be written for OS X, as there reports on
problems with PortMidi on that platform.

>>> l) Making re-entrant
>>>    -----------------

Some opcodes that make heavy use of statics (e.g. sfont.c,
many "spectral" opcodes, etc.) still have problems.
The engine and major parts (parser, event system, audio I/O, MIDI,
score read, most of the opcodes, etc.) are OK however, other than
possibly some Mac specific code in dl_opcodes.c that has a few
local static variables.

Dear Developers,

Once you all feel that this document is a reasonably accurate and
comprehensive picture of where we are currently at currently Csound5, David
Akbari and I would like to post a finished version in the news at
cSounds.com and in the Csound5 developers section.

Could you continue to develop this document a bit and then email me/us a
finished version/consensus?

Thanks,

Dr. B.
