DigiSID Final Release
Posted by: icabod on Friday, October 24, 2003 - 11:29

In something of a raww.org exclusive, I've been sent the Final
Release of "DigiSID", a music-player originally shown at the
recent Zlincon 2003 party. The player, written by Poke, demos
the emulation of ST tunes (with SID voice) on a Speccy.
It sounds... well I don't actually know coz I'm at work, but
according to reports it's very good. So you should download it
for yourself and check it out. Some info about the player
follows...

    Optimal machine (for best sound quality):
    - ZX 128, +2, +2a, +3.
    Optimal emulator(for best sound quality):
    - SPIN, SPECTACULATOR, KLIVE.

    DigiSID sound routine need absolute frequency precision
    for: Z80,AY and ULA. If this options isn't filled, sound is
    poor and maybe border line is moving in frame.

    Sorry Pentagon and Scorpion users. You haven't original
    Speccy128. You haven't correct ULA and AY timing.

    Original ZX128 parameters which must be filled:
    Main ZX Frequency = 35.4690Mhz (or 2*17.734475Mhz for
    ZX128)
    ULA128 Frame profile: 311 * 228T
    - (70908T per Frame)
    CPU clock frequency = Main ZX Frequency / 10
    - (3.54690 Mhz generate from Main ZX Frequency xtal)
    AY clock frequency = Main ZX Frequency / 20
    - (1.77345 Mhz generate from Main ZX Frequency xtal)
