  1. *bump*

    Since this idea was last dug-into, there have been some interesting developments in the AY-3-8912 world. Check out http://en.wikipedia.org/wiki/General_Instruments_AY-3-8912#Uses about the Viterbi Search, It's really neat.

    In 2006 two MSX developers created an advanced encoder that converts a wave file to optimal PSG channel transitions using Viterbi search. They replayed a 44.1kHz wave file on a 23 year old MSX with higher SNR than an 8-bit DAC. The Viterbi search is rather CPU intensive so even though it would have been theoretically possible to use this method already in the 80's, there were no computers powerful enough to perform the analysis required.

    Music sample played on a Philips VG-8020 demonstrating the Viterbi encoded AY sample player  :o :o :o (The VG-8020 has the AY-3-8910 inside)

    I wonder what kind of processor we'd need to calculate Viterbi on-the-fly  ???

    Edit: I guess I should have wiki-searched 8912 instead of 8910... http://www.midibox.org/dokuwiki/midibox_ay_3_8912?s=3+8912.. Still leaves the Viterbi question open though.

  2. Not to put off the current chat room, but it would be a lot easier (for me, at least) to be able to connect with IRC.

    Here are some reasons, from my point of view:

    • Leaving a window open just to have chat is kind of a pain, and also a hog
    • There's no visual notification of a new message, only sound. (I have sounds turned off so as not to disturb others)
    • I already have an IRC app running (Many people will have [Windows] MIRC, Trillian, Pidgin, etc, or [linux] xIRC, Kopete, Pidgin, etc)
    • You can get IRC clients for many different platforms

    We could always use PJIRC (http://www.pjirc.com/main.php) for the "Chat" page, which would allow us to connect by way of other applications, too  ;D

    Just a suggestion  ;D
