Digital audio broadcasting
Digital audio broadcasting (DAB) is a digital radio technology for broadcasting radio stations, used in several countries across Europe and Asia Pacific.
The DAB standard was initiated as a European research project in the 1980s. The Norwegian Broadcasting Corporation (NRK) launched the very first DAB channel in the world on 1 June 1995 (NRK Klassisk), and the BBC and SR launched their first DAB digital radio broadcasts in September 1995. DAB receivers have been available in many countries since the end of the 1990s.
DAB may offer more radio programmes over a specific spectrum than analogue FM radio. DAB is more robust with regard to noise and multipath fading for mobile listening, since DAB reception quality first degrades rapidly when the signal strength falls below a critical threshold, whereas FM reception quality degrades slowly with the decreasing signal.
Audio quality varies depending on the bitrate used and audio material. Most stations use a bit rate of 128 kbit/s or less with the MP2 audio codec, which requires 160 kbit/s to achieve perceived FM quality. 128 kbit/s gives better dynamic range or signal-to-noise ratio than FM radio, but a more smeared stereo image, and an upper cut-off frequency of 14 kHz, corresponding to 15 kHz of FM radio. However, "CD sound quality" with MP2 is possible "with 256…192 kbps".

Eden
by: Die HappyThere's war in the heavens
Rebellion on high
the son of the morning
Descends from a black sky
Severed and broken
His wings burned to dust
His coverings of diamonds and gold
In a moment in time dissolve to rust
Thunder and lightning
Shatter the night
The dragon of darkness
Appears cursed by the keeper of the light
The dark is chosen
The scroll has been sealed
Hidden in verses of prophets
His face is revealed
Songs of glory
Shout across the land
I can take you there
Child of mine, take my hand
Down through the ages
The story's been told
The daughter of wisdom
Beguiled by the serpent of old
Born into sin in a valley of thorns
Torn from enchantment and
Tossed into the eye of the storm
Heaven's garden
Made by God for man
This is paradise
Child of mine, take my hand
Glory to glory
Sin after sin
The rider of death
Pushes on to the place where
The battle must begin
Songs of glory
Shout across the land
This is paradise
Won't you take my hand
Heaven's garden
Made by God for man
This is paradise
Child of mine, take my hand
Oh, take my hand
