The True Audio (TTA) codec is a popular, free, simple, realtime lossless audio compressor. In difference from its competitors, TTA features the symmetric and adaptive algorithm, small delays in work with a stream and the ability of password data protection. The current goal of the project - adaptation of the codec algorithms to use in systems of secure IP-telephony.
Designed audio compressor has good compression rate from 30% to 70% of the original, ultra low latency about 0.1 ms, low resource consumption and high cryptographic strength, provided by possibility of encoding audio data with 64-bit encryption key.
TTA codec is able to provide high quality and ensure the security of the voice calls in IP-telephony. Implementation of the TTA codec support into popular models of IP-phones and software of IP-telephone stations will provide users with simple and inexpensive tool for providing quality and cryptographic protection of telephone calls....
