Low-complexity MDCT audio codec

  1. 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.
  2. 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'.
  3. 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
