  • The tracker now uses 2x oversampling and decimation for mixing and filtering for (theoretically) less aliasing
  • Added Amiga 1200 low-pass filter (~34.4kHz, when not in A500 mode). This makes sense now, since we have twice the render/filter frequency than before.
  • PAT2SMP now renders in higher quality thanks to the new high quality 2x decimator routine. Especially noticable in LO mode on high-frequency content.
  • The "2x downsample" option while loading samples results in slightly less aliasing than before because of the new high quality 2x decimator
  • The MOD2WAV audio rate is now the same as the tracker's audio rate
  • Stereo separation now works like it should. The volume is a bit louder than before if you increase the separation, but that's expected.
  • Removed the hand-made cutoff tweak on the Amiga 500 low-pass filter. It now uses the correct nominal cutoff frequency. The RC filter routines have been replaced with new ones, and with these I didn't have to tweak the cutoff to make it sound similar to an A500 (probably related to filter prewarping?).
  • Windows/macOS: Updated SDL2 from version 2.0.14 to 2.0.16
