David you are the man to ask this one Why do (or why do you think) relatively benign companding algorithms like Alaw, uLaw, that are commonly used for encoding for VOIP links for radio systems (and other) , sounds so awful when they pass AMBE/ AMBE2 etc processed speech ?
Must be something to do we the re distribution of the quantizating noise characteristics? Not sure what the effect is yet with codec2, but that would be a cinch to test up. g ------------------------------------------------------------------------------ _______________________________________________ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freetel-codec2
