This version of TiMidity should contain all the fixes from the
September 25 2003 SDL_mixer CVS snapshot. In addition, I've made some
changes of my own, e.g.:
* All file access is done through SDL_RWops. This means the MIDI
stream no longer has to be a file. (The config file and instruments
still have to be though.)
* Replacing of TiMidity's endian-handling with SDL's.
* Removal of much unused or unnecessary code, such as
+ The "hooks" for putting a user interface onto TiMidity.
+ The antialias filter. It wasn't active, and even at 4 kHz I
couldn't hear any difference when activating it.
+ Removed all traces of LOOKUP_HACK and LOOKUP_INTERPOLATION.
According to the code comments they weren't very good anyway.
("degrades sound quality noticeably"). I also removed the
disclaimer about the "8-bit uLaw to 16-bit PCM and the 13-bit-PCM
to 8-bit uLaw tables" disclaimer, since I believe those were the
tables I removed.
+ Removed LOOKUP_SINE since it was already commented out. I think we
can count on our target audience having math co-processors
nowadays.
+ Removed USE_LDEXP since it wasn't being used and "it doesn't make
much of a difference either way".
+ Removed decompress hack from open_file() since it didn't look very
portable.
+ Removed heaps of unnecessary constants.
+ Removed unused functions.
+ Assume that LINEAR_INTERPOLATION is always used, so remove all
code dealing with it not being so. It's not that I think the
difference in audio quality is that great, but since it wouldn't
compile without code changes I assume no one's used it for quite
some time...
+ Assume PRECALC_LOOPS is always defined. Judging by the comments it
may not make much of a difference either way, so why maintain two
versions of the same code?
* Moving several static globals into the MidiSong struct. This
includes sample rate, formate, etc. which are now all per-song.
* Moved some typedefs (e.g. MidiSong) to timidity.h for easy inclusion
into the MIDI decoder.
* Added free_pathlist().
* Replaced TiMidity's own 8, 16 and 32-bit types with SDL's.
* Made TiMidity look for its configuration file in both /etc and
/usr/local/lib/timidity. (Windows version remains unchanged.)
* Timidity_PlaySome() now takes three arguments. A MidiSong, a decode
buffer and decode buffer size in bytes. (MidiSong is a new argument,
and buffer size used to be in samples.)
In addition, it will return the number of bytes decoded.
* Added Timidity_Exit().
* Removed Timidity_Stop() and Timidity_Active(). Stopping playback
should be handled by SDL_sound, and Timidity_PlaySome() will return
0 when the MIDI stream is finished.
* Modified the ToneBank stuff to allow some data to be shared between
MidiSongs.
* The following files have been removed: controls.c, controls.h,
filter.c, filter.h, sdl_a.c, sdl_c.c
* config.h has been renamed as options.h to avoid confusion with the
automatically generated config.h for SDL_sound.
* Added support for loading DLS format instruments:
Timidity_LoadDLS(), Timidity_FreeDLS(), Timidity_LoadDLSSong()
* Added Timidity_Init_NoConfig()
