""" The standard also specifies the form of digital audio encoding: 2-channel signed 16-bit Linear PCM sampled at 44,100 Hz. "
""" An audio CD can represent frequencies up to 22.05 kHz, the Nyquist frequency of the 44.1 kHz sample rate. """
"" The Nyquist frequency, named after electronic engineer Harry Nyquist, is half of the sampling rate of a discrete signal processing system.[ ""
"""
In digital audio, 44,100 Hz (alternately represented as 44.1 kHz) is a common sampling frequency. Analog audio is recorded by sampling it 44,100 times per second, and then these samples are used to reconstruct the audio signal when playing it back.
The 44.1 kHz audio sampling rate is widely used due to the compact disc (CD) format, dating back to its use by Sony from 1979. """
Now, a Studer A80 proffesional studio recorder extremely well regarded R2R machine goes only to 20khz at 30ips. plus,minus 2dbs. Other regarded R2R machines does not makes things a lot better and always has the printthough problems with and the quality of the used tapes and quality of those recording/play R2R tape heads. Other " problem " is that all R2R machines develops odd harmonics.
It can't compete with a flat CD frequency response or with the CD very low noise and non-existen wow&flutter coming in the R2R machines.
That you like what you are listening is no evidence/fact of superiority against the redbook in today CDP.
Each medium alternative has its native players that is the best way to go with either format.
Regards and enjoy the MUSIC NOT DISTORTIONS,
