Emax

Hi,
Emax is usally considered to be 12-bits because thats the resolution of the
ADC/DAC''s and thats the resolution of sample stored to disk. However the
Emax sample replay chip uses 16-bit audio data, 24-bits in the DSP to
maintain 16-bit precision, and manipulates samples that are compressed into
8-bits. All rather confusing ! And all done with 50,000 transistors.

The bottom line is Dave Rossum designed quite an effective sample replay
chip with some neat DSP tricks to reduce pitch shift distortion (for
12-bits....). Not at all like a 12-bit linear sampler like the Akai S900,
and well worth using even today. The Emax was designed to sound good, rather
have great technical specs.

Regards
Rob

The emax is 12bit isnt it.
