Hi Bruce, Good question.
I am not sure what's required to make very high pitched voices (such as children) more intelligible through codecs. Having said that I know my 6 year old can be hard to understand through a mobile. The current frequency range is adequate for all speakers I have heard processed through Codec 2. It's pretty consistent with every other codec that I can think of. - David On Tue, 2012-02-07 at 15:50 -0800, Bruce Perens wrote: > David, > > Is there any performance improvement, particularly in high-pitched > voices, from using the current 10 LSPs but a higher sampling rate, more > buckets in the FFT, and maybe one more bit in the fundamental pitch? > > Or is this meaningless until we increase the resolution of the frequency > information by adding LSPs? > ------------------------------------------------------------------------------ > Keep Your Developer Skills Current with LearnDevNow! > The most comprehensive online learning library for Microsoft developers > is just $99.99!
