Re: melpe pls send information and source codes related to melpe vocoder
MELP

One good approach is frequency domain echo cancellation (adaptive filtering)
https://people.xiph.org/~jm/papers/valin_tasl2007.pdf
This algorithm is implemented in SPEEX open source project
https://www.speex.org/downloads/
More traditional method is NLMS (or RLS) adaptive filtering in time...

Well, the simplest way is to permute image brightness by XOR operation
You reorder image samples in 1-dimension sequence by scanning and XOR them by random sequence
Then You can restore image by XOR as well
pseudo random permutation
It means: to destroy spatial correlations like areas or contours

For arbitrary fractional delay Catmul-Rom Splines usually used

vocoder application
Most of MELP source code is written in C. But this one is written in Matlab :-)

Exactly what you need
It shoud be running
"Rounding is something
you do in preparation to trimming off less-significant bits; saturation
is something you must do when trimming off more-significant bits."
