Abstract:
A system comprising:a first telecommunication device coupled to a network to compress input data received via the network at a rate adjusted to improve data bandwidth while data integrity is maintained, said first telecommunication device compresses input data by setting priorities of each of a plurality of epoch data parameters based on said plurality of epoch data parameters influence on quality, and reducing said plurality of epoch data parameters based on each of said plurality of epoch data parameters respective dynamic priority based on trends and change of value from frame to frame, wherein said plurality of epoch data parameters include epoch length, epoch RMS value, a plurality of reflection coefficients and at least two residue descriptors, wherein the plurality of reflection coefficients are used to construct an inverse filter and the inverse filter is applied to an audio epoch to obtain an excitation residue used to derive the at least two residue descriptors; a first router coupled to the first telecommunication device; a gateway coupled to the first router and a second router; and a second telecommunication device coupled to the second router, the second telecommunication device to decompress received data.
