< 18 > Digital audio started with Compact Disc and has since given birth to such super high-fidelity formats as DVD Audio and SACD. There’s another trend in digital audio: compressed data for mats.
< 19 > In digital audio, music is pr ocessed in digital form. The mu sic played by musicians in a recording studio or a conc ert hall is picked up by a micropho n e and record ed in digital form, to be released for sale as packa ged media, including CD.
< 20 > When its level is high, a 1kHz signal can produc e a smooth waveform after the A/D and D/A conversion. When the level is low, how ever, a st epped waveform results du e to the limitation in the resolution of a digital signal. This phenomenon occurs becaus e digital quantizati on distortion increases as the levels are reduced.
< 21 > The “sampling theorem” says that, if the sampling frequency is m ore than twice as hig h as the maximum frequency of original signal, then th e original signal can be retri eved by A/D and D/A conversion. With CDs , the sampling frequ ency is 44.
< 22 > The CC Converter was developed to solve t he probl ems with digital conversion by (1) increasing quantization r esolution for low-level signals and (2) increasi ng the sampling frequency for hig h-frequency sig nals.
< 23 > In the bit expansion section, t he JVC-exclusive hi-fi processing generates a high-resoluti on 24-bit digital signal from a 16-bit signal. The proc ess first analyzes the 16-b it digital si gnal to deduce the original analo g signal before A/D conv ersion, and then appl ies hi-bit expansion to smooth the signal waveform.
< 24 > The frequency conversion sectio n doubles or quadruples the sampling frequency for pl ayback of high-frequency s ignals t hat a following stage generates.
< 25 > There are several high-bit/upsampling processing systems on the market that clai m to offer the same benefits as the CC Converter. They are all designed to create and add frequencies (harmonics) over 2 0kHz deriving from an input signal.
< 26 > The figure shows the actual measured waveform of a bi t-expanded -90dB sinusoidal signal. -90dB, 1kHz Sine Wav e: Bit Expans ion Off The figure shows the frequency spectra of a music signal with the range expansio n on and off. With the expansio n off, the level is sharply red uced beyond 2 2kHz.
