MELPe vs. IMBE

Started by CR February 3, 2006
Does anyone have any results of quality comparison between IMBE (or 
AMBE) and MELPe at rates 2400, 1200, 600 bps?
I heard MELPe sounds much better, is that true?
What about other aspects such as robustness to background noise & 
channel errors?

MELP has better quality then MBE because MELP model is more adequate. The difference is very noticeable at the rates of 2400 and below. The only advantage of MBE is in the low computation and memory requirements. Vladimir Vassilevsky DSP and Mixed Signal Design Consultant http://www.abvolt.com
