EVRC - (Enhanced Variable Rate Codec) EVRC is a
new global standard for compressing and
decompressing voice signals. EVRC uses a lower
bit rate (the number of bits sent per second) than
existing CDMA vocoders, while providing
significant improvements in voice quality. This
technology enables your phone to provide superb
voice quality while benefiting from the ability to
process more cellular voice calls using less
bandwidth than the voice codecs in CDMA
networks today.
