This code is almost the exact same as a Computer magazine article in 1986... but the SFX that is based off this is vastly different (for obvious reasons). The special thing about this is the recording method to use the 2nd lowest available bitrate this code can handle (under normal circumstances you really cant use value speed 8, as its far too few bits per second. Its a highly crafted combination of equalizer and volume settings. In normal day to day operations I tend to use value speed 5, along with the equalizer we get some pretty impressive quality music for the data spent.... as shown with DogFighters of Mars 2 (main game).

I have worked on trying to get 1bit PC WAV files into the apple unsuccessfully... and must currently record everything on the back of a IIE. If we can make some sort of converter that the apple can read (and have the same low bit rates), I think quality can improve almost 100% from what has been achieved so far. I am not knowledgeable enough about WAV or how non-apple stuff works, so I am unable to do it. Michael M the sound genius has done it, but his bitrates are very high. His main focus on his work was quality at any cost... and he did it, but his 'released' program did something like 2.5 seconds... im sure he has prototype stuff on his drive somewhere that can do far better lengths.

SFX2 in the works takes a recorded instrument scale (possibly upto 3 instruments), incorporates it with a midi-converter and the output can have an entire song with a sound font footprint of 2k an instrument, plus the midi/note data. It again wont have the 'quality' of Mahon's stuff, but the focus is to create a multi-tasking mockingboard audio experience with game code running in the background. It will suffice for those without expansion hardware!
