Re-equalized track

Because of the GBA's 8bit audio DAC, I had to perform a lot of equalization to get the track to sound right. After listening to it a lot more and comparing to the original, I realized I wasn't doing it justice and started the equalization process from scratch; sounds a lot closer to the original now. May have gone overboard on the bass, though...

Latest build

Hadn't intended to update on here any further, but made a major breakthrough in quality. Additionally, new interface should look more slick.

Rebuild with latest source/tools

Quality improvements from new a quantizer selection strategy. Not all /that/ noticeable in this demo (especially from an integer DCT), but more high-frequency bands are kept now, making things sound 'clearer'.

Rebuild with latest source/tools

  • Fixed a bug that might've caused audio glitching when Timer1 interrupt was interrupted by VBlank interrupt
  • Minor improvements to quantizer optimization in encoder
  • Micro-optimizations in DCT-II/DCT-IV routines

    Stayin inside for memorial day. Just like other holidays, most people dont care or think about the actual reasons behind it. For most it's just another reason to get shit faced drunk and spout off hyper-patriotic nonsense. The Trumpers around here going to be out in full force with their trucks and guns and flags making noise all over town. Hard pass.
