Commit message and the brunt of the code courtesy of intrr, apologies for the size of this; Finally, the Sequencer audio support and global audio/animation sync stuff! (See http://intrr.org/blender/audiosequencer.html) Stuff that has been done: ./source/blender/blenloader/intern/writefile.c ./source/blender/blenloader/intern/readfile.c Added code to make it handle sounds used by audio strips, and to convert Scene data from older (<2.28) versions to init Scene global audio settings (Scene->audio) to defaults. ./source/blender/include/BSE_seqaudio.h ./source/blender/src/seqaudio.c The main audio routines that start/stop/scrub the audio stream at a certain frame position, provide the frame reference for the current stream position, mix the audio, convert the audio, mixdown the audio into a file. ./source/blender/makesdna/DNA_sound_types.h Introduced new variables in the bSound struct to accomodate the sample data after converted to the scene's global mixing format (stream, streamlen). Also added a new flag SOUND_FLAGS_SEQUENCE that gets set if the Sound belongs to a sequence strip. ./source/blender/makesdna/DNA_scene_types.h Added AudioData struct, which holds scene-global audio settings. ./source/blender/makesdna/DNA_sequence_types.h Added support for audio strips. Some variables to hold Panning/Attenuation information, position information, reference to the sample, and some flags. ./source/blender/makesdna/DNA_userdef_types.h ./source/blender/src/usiblender.c Added a "Mixing buffer size" userpref. Made the versions stuff initialize it to a default for versions <2.28. ./source/blender/makesdna/DNA_space_types.h ./source/blender/src/filesel.c Added a Cyan dot to .WAV files. Any other suggestions on a better color? :) ./source/blender/src/editsound.c Changes (fixes) to the WAV file loader, re-enabled some gameengine code that is needed for dealing with bSounds and bSamples. ./source/blender/src/editipo.c ./source/blender/src/drawseq.c ./source/blender/src/editnla.c ./source/blender/src/space.c ./source/blender/src/drawview.c ./source/blender/src/renderwin.c ./source/blender/src/headerbuttons.c - Created two different wrappers for update_for_newframe(), one which scrubs the audio, one which doesn't. - Replaced some of the occurences of update_for_newframe() with update_for_newframe_muted(), which doesn't scrub the audio. - In drawview.c: Changed the synchronization scheme to get the current audio position from the audio engine, and use that as a reference for setting CFRA. Implements a/v sync and framedrop. - In editipo.c: Changed handling of Fac IPOs to be usable for audio strips as volume envelopes. - In space.c: Added the mixing buffer size Userpref, enabled audio scrubbing (update_for_newframe()) for moving the sequence editor framebar. ./source/blender/src/editseq.c Added support for audio strips and a default directory for WAV files which gets saved from the last Shift-A operation. ./source/blender/src/buttons.c Added Scene-global audio sequencer settings in Sound buttons. ./source/blender/src/sequence.c Various stuff that deals with handling audio strips differently than usual strips.
