They're currently treated as non-fatal, those sounds just won't ever
play. This allows ad_tears to at least load with only 32MB of locked
memory (it needs somewhere between 64 and 96).
Sounds no longer use the cache, which is good for multi-threaded, but a
pain for memory management: the buffers are shared between channels that
play back the sounds, but when the sounds were cached, they were
automagically (thus problematically) freed when the space was needed.
That no longer happens, so they leak. I think the solution is to use
reference counting and retain/release in sfx->open() and sfx->close().
Sounds in Arcane Dimensions (at least those used by ad_tears) specify
start and end cue points. The code was using only the final point in the
list and thus breaking looped sounds. Now, the first cue point is used
as the loop start, and the second (if present), the sample length. Both
are bounds-checked against the wav's sample count. Fixes sound locking
up during the first seconds in ad_tears.
Wav file were not read correctly when encoutering most chunk type beside the ones used by QuakeForge.
This patch will fix the riff loader code so that unused but defined chunk are skipped. Most wav files should now be loaded correctly fixing some silent sound effect.
Also fixed a typo in wav loader and reordered wav validity check so that format is checked first. The data chunk could be inexistant on some weird format and so an invalid format is a more helpful error text.
! Fix: Skip unsupported chunk in riff loader instead of rejecting riff file.
! Fix: typo in Microsoft name.
! Fix: ordering of wav validity to enable more helpful error text.
The sounds are down-mixed to 2 channels (qf does not (yet) support more than
2 channel output), but this allows pretty much anything to be used for a
source of music. Only 5.1 (6 channel), stereo and mono have been tested, but
the others should work (any issues would be mis-interpretation/implementation
of the channel layout).
the resampler is being badly abused for streams, and it's not yet properly
autoconfiscated, but things are working. Better yet, at the correct pitch and
speed.
