G.719 is an ITU-T standard audio coding format providing high quality, moderate bit rate (32 to 128 kbit/s) wideband (20 Hz - 20 kHz audio bandwidth, 48 kHz audio sample rate) audio coding at low computational load. It was produced through a collaboration between Polycom and Ericsson.
G.719 incorporates elements of Polycom's Siren22 codec (22 kHz) and Ericsson codec technology, as well as Polycom's Siren7 and Siren14 codecs (G.722.1 and G.722.1 Annex C), which have been used in videoconferencing systems for many years. As ITU-T Recommendation G.719, it was approved on June 13, 2008.
G.719 is optimized for both speech and music. It is based on transform coding with adaptive time-resolution, adaptive bit-allocation and low complexity lattice vector quantization. The computational complexity is quite low (18 floating-point MIPS) for an efficient high-quality compressor. The codec operates on 20 ms frames, and the algorithmic delay end-to-end is 40 ms. The encoder input and decoder output are sampled at 48 kHz.
I'm gonna tell you a well known story
A sacrifice of innocents
24 days of agony
How a last dive, gave them no chance
Somewhere in the arctic, the Russians were telling a
Forgotten by the world
In the rescue chamber, flooded with water
A.D. had to die
Hell awaits the enemy, somewhere in the Barents sea
The system is failing
Hell awaits the enemy, victim of hypocrisy
The system is lying
They will never come back home again
And I've lost another friend
They will never come back home
They are the victims of a vicious game
Commanders of the Russian fleet
Decided to conceal the truth
Somewhere down in the deep
The wreck revealed, they could have saved you
In a grave of steel, the truth was so real
Locked in the shell, their own private hell
One day we all will know why
Hell awaits the enemy, somewhere in the Barents sea
The system is failing
Hell awaits the enemy, victim of hypocrisy
The system is lying
They will never come back home again
And I've lost another friend
They will never come back home
They are the victims of a vicious game...
They will never come back home again
