869b041f2f Reduce the default buffer size to 4096 
Should help with latency issues some people have and not put too much extra
burden on the mixer, hopefully

e2ed8ff2bf Use a temp pointer when realloc()ing 
So the original data isn't lost on out-of-memory conditions

559c786d0c Specify padding per buffer, and make sure it's large enough for the filter step 2008-07-24 00:41:25 -07:00

c3a7480961 Don't advertise extra samples for mixing 2008-07-23 23:27:38 -07:00

a75e75aef5 Implement an alternative low-pass filter 
This method samples from the buffer so that it gets a time-correct 5khz stream,
which is subtracted from the original sample and has the high-frequency gain
applied, then added back.
A better method may be to average all the samples from the current one to the
one freq/5000 away, instead of bilinear filtering the two nearest freq/5000
apart. Processing cost will need to determine its viability

97d3a45aff Don't check the number of objects being deleted with the number currently allocated 
Since apps can validly delete buffer 0, and delete the same source/buffer multiple times in a single call

f369be148f Reduce the mix buffer sizes by half 
Nearly 3MB is a bit much. Could reduce it further, but this is good enough for now.

3a09e446b3 Leave SourceToListener untransformed for use with untransformed velocities 
Distance is also left untransformed so cone calculations with SoundToListener
are correct

ca6feeda29 Make sure the lib is initialized when shutting down 
Pretty ugly, but the destructor sequence relies in the mutex being initialized
