In Reply to: WRONG Digital Audio IS staircase, dither (analog noise) is added to the digital signal to smooth out the rough edges posted by Teresa on September 13, 2006 at 21:27:02:
The sample rate of a 44.1khz 16 bit cd is really close to the upper limits of a human ear hearing any difference between a DA signal and an analog master tape.A DVD-A recording at 96khz eclipses any possibility that the human ear can hear a difference in the signal. You might hear a difference between the playback devices but not in the signal itself.
The staircase description shown by the graph is completely wrong. I have seen the actual graphs done by the HDCD people and 20 bit 44.1khz actually sounds pretty awesome to my ears. HDCD was designed to completely match the limits of human hearing in the DA signal to an analog master tape. Just read their published literature if you want to learn more about the perceived inadequacy of CD redbook recordings.
Dithering is a whole different issue all together. Dithering does not smooth the staircase. It actually adds a noise floor to the digital recording. Without it the human ear could not hear the low level detail in the music. The background would be so silent that the human ear could not hear the quiet inner detail at all.
This was discovered very early by Philips engineers.
Dithering is added by a studio to be just what is necessary to uncover the low level details and is generally much lower noise than a Master tape hiss and certainly much lower than an LP's surface noise.
I wish we could stop digital bashing. Software is software. It is neither good nor bad it is simply a reproduction of what had been a performance. Enjoy the music not the media. I am after the magic of the performance not the technology of the playback.
