* Some fixes to linear interpolation
* Adds interpolation to ADPCM samples
* Relaxed a volume limit in ADPCM_Vol






Fixed:
- Frac rolls over one iteration before samplePos advances. Can introduce noise similar to flipping samples (1234 => 1214). Introduced oldFrac to fix this. This isn't as noticeable as it probably should be because of below.

- When samplePos doesn't advance it interpolates between two copies of the same sample which actually does nothing. Changed it to always use the current and next sample.

- When frac is 0 you should get 100% of yn2 instead of ~99% added a +yn2 to balance it.


Other changes:
- Added linear interpolation for ADPCM. Sounds like a good idea.

- Set ADPCM_Vol to clamp to x8000 instead of x4e20. Some games will play some sounds at x8000 volume anyways since the volume is applied before this. Lower limit can result in quiet music (x4e20) but some loud ambient sounds (0x8000).

PluginSpecs Removed the hackery that was being done with the plugin configuration dialogs on windows. That was unnecessary and ugly. The HWND type is dead for non windows. Also cleaned up the gui a little. 2010-07-30 03:51:49 +00:00
