The EMU10K1 digital audio processor

T.C. Savell
1999 IEEE Micro  
It has a 64-channel wavetable synthesizer with perchannel sample rate converter, digital filter, envelope generator, low-frequency oscillator, and routing/mixing logic.  ...  These needs led our company to produce the EMU10K1 digital audio processor, which places both a high-quality music synthesizer and a powerful audio effects processor on the same die.  ...  Digital audio is simply a numeric representation of an analog waveform. There are infinitely many digital representations of the same analog waveform.  ...
