In any case, any application with high quality audio for the time (here I'm thinking something like Dark Castle, which actually has really great sound effects) probably either just lived with the iffy quality or pre-equalized the audio, but given that Dark Castle sounds pretty
Don't forget that a few guys started making replacement ROMs for a commercial drum machine called DigiDrums I think. They made a tool for editing their data, which they then expanded to a I think a 4 channel sound card for the Mac. They called their company DigiDesign and it allowed users to record multitrack audio at high quality on the Mac And the rest is history..... (DigiDesign = Protools, one of the big digital audio workstation hardware/software platforms.)
