Summary0003969: Using "machine_hum04_loop" as a sound shader on a light causes crash to desktop
DescriptionDiscovered this in a map of Biker's that was crashing. Lots of lights have a sound shader that adjusts the light level in that map, but only this one seems to cause a crash.

Most of those shaders are WAVs, but this one is an OGG.

The crash occurs after idSoundWorldLocal::FindAmplitude calls SIMD code to get a sample. The stack is being corrupted around the "sourceBuffer" array pointer, which is written to by the SIMD code.
Steps To ReproduceTest map attached. The crash will happen within a few seconds but not immediately.
Additional InformationI tried greebo's fix for dangling ogg pointers 0003804 but it doesn't help here.

Since "sound\ambient\environmental\machine_hum04_loop.ogg" is stereo method UpSampleOGGTo44kHz produces twice more data into provided buffer.

Attached a document with "suspicious" audio files.
First sheet contains list of all stereo files.
Second sheet contains list of audio files with non-optimal (not equal to 44100 Hz) sampling rate.

Wow do we really have that many stereo sounds? I thought we shouldn't have stereo sounds in game because the sound system itself take care of placing the source of the sound. Ah, I found an existing tracker. It's not quite that bad, it's just point sounds apparently that are a problem in stereo.

Thanks for the detective work!

This is complicated to fix and has an easy workaround. Bumping to 2.05.

 nb. in the city map Im working on that you refereed too, simply changing the shader fixed the crash. So as a quick fix could be not just edit the .MTR for any lights that use that sound..?

Not using any stereo sounds as light shaders is the quick fix, if I remember right.

If it helps or if it's any consolation: early on, we were experimenting with giving machine sounds a cool T2-style 'swirl' type effect by reversing one of the audio channels. This was, apparently, the same technique they used for some machines in T2, and it required stereo rather than mono.

That's the main reason why some of my ambient sounds were in stereo. Here's a thread that talked about the technique: http://forums.thedarkmod.com/topic/1048-machine-sounds/

Commented out the two resampling methods of idSIMD_SSE. The methods from idSIMD_Generic work properly.
Committed in SVN rev 7123.

I profiled running around training mission afterwards:
  idSIMD_Generic::UpSampleOGGTo44kHz 7
  idSIMD_SSE::DeriveTangents 832
  ov_read_float 2988
So upsampling takes 400 times less time than OGG decoding itself.
