| 1 This version of TiMidity should contain all the fixes from the | |
| 2 December 13 2001 SDL_mixer CVS snapshot. In addition, I've made some | |
| 3 changes of my own, e.g.: | |
| 4 | |
| 5 * All file access is done through SDL_RWops. This means the MIDI | |
| 6 stream no longer has to be a file. (The config file and instruments | |
| 7 still have to be though.) | |
| 8 | |
| 9 * Replacing of TiMidity's endian-handling with SDL's. | |
| 10 | |
| 11 * Removal of much unused or unnecessary code, such as | |
| 12 | |
| 13 + The "hooks" for putting a user interface onto TiMidity. | |
| 14 + The antialias filter. It wasn't active, and even at 4 kHz I | |
| 15 couldn't hear any difference when activating it. | |
| 16 + Removed all traces of LOOKUP_HACK and LOOKUP_INTERPOLATION. | |
| 17 According to the code comments they weren't very good anyway. | |
| 18 ("degrades sound quality noticeably"). I also removed the | |
| 19 disclaimer about the "8-bit uLaw to 16-bit PCM and the 13-bit-PCM | |
| 20 to 8-bit uLaw tables" disclaimer, since I believe those were the | |
| 21 tables I removed. | |
| 22 + Removed LOOKUP_SINE since it was already commented out. I think we | |
| 23 can count on our target audience having math co-processors | |
| 24 nowadays. | |
| 25 + Removed USE_LDEXP since it wasn't being used and "it doesn't make | |
| 26 much of a difference either way". | |
| 27 + Removed decompress hack from open_file() since it didn't look very | |
| 28 portable. | |
| 29 + Removed heaps of unnecessary constants. | |
| 30 + Removed unused functions. | |
| 31 + Assume that LINEAR_INTERPOLATION is always used, so remove all | |
| 32 code dealing with it not being so. It's not that I think the | |
| 33 difference in audio quality is that great, but since it wouldn't | |
| 34 compile without code changes I assume no one's used it for quite | |
| 35 some time... | |
| 36 + Assume PRECALC_LOOPS is always defined. Judging by the comments it | |
| 37 may not make much of a difference either way, so why maintain two | |
| 38 versions of the same code? | |
| 39 | |
| 40 * Moving several static globals into the MidiSong struct. This | |
| 41 includes sample rate, formate, etc. which are now all per-song. | |
| 42 | |
| 43 * Moved some typedefs (e.g. MidiSong) to timidity.h for easy inclusion | |
| 44 into the MIDI decoder. | |
| 45 | |
| 46 * Added free_pathlist(). | |
| 47 | |
| 48 * Replaced TiMidity's own 8, 16 and 32-bit types with SDL's. | |
| 49 | |
| 50 * Made TiMidity look for its configuration file in both /etc and | |
| 51 /usr/local/lib/timidity. (Windows version remains unchanged.) | |
| 52 | |
| 53 * Timidity_PlaySome() now takes three arguments. A MidiSong, a decode | |
| 54 buffer and decode buffer size in bytes. (MidiSong is a new argument, | |
| 55 and buffer size used to be in samples.) | |
| 56 | |
| 57 In addition, it will return the number of bytes decoded. | |
| 58 | |
| 59 * Added Timidity_Exit(). | |
| 60 | |
| 61 * Removed Timidity_Stop() and Timidity_Active(). Stopping playback | |
| 62 should be handled by SDL_sound, and Timidity_PlaySome() will return | |
| 63 0 when the MIDI stream is finished. | |
| 64 | |
| 65 * Modified the ToneBank stuff to allow some data to be shared between | |
| 66 MidiSongs. | |
| 67 | |
| 68 * The following files have been removed: controls.c, controls.h, | |
| 69 filter.c, filter.h, sdl_a.c, sdl_c.c | |
| 70 | |
| 71 * config.h has been renamed as options.h to avoid confusion with the | |
| 72 automatically generated config.h for SDL_sound. |
