The audio codec is CVSD
15.625 kbps; cross accessing and data buffer pool are introduced to reduce hardware requirement and power consumption.
Kite explained that CVSD
codecs, for example, are notorious for providing voice quality that's tolerable--good enough for a phone call--but not great.
The Brambles Primary School pupil suffers from a complete ventricular septal defect (CVSD
) and the left hand side of her heart is missing.
Voice coding is accomplished using the continuously variable slope delta (CVSD
) modulation technique.
Voice channels can be provided over these digital links by using phase-code modulation (PCM) or continous-variable-slope delta modulation (CVSD
The Wavpac also loads a variety of digital voice waveforms, including CVSD
and Melpe (600,1200,2400).
