CodecPro QCELP Codec
TIA 3GPP2 standard codec

QCELP-13 is a variable-rate codec operating at four bitrates and dynamically adjusting the rate depending on the source signal (source codec). Typical conversational speech yields an average data rate of around 6.6 kbps, and the codec can also trade a reduced average data rate for slightly reduced voice quality.

The memory and CPU details are generic Standard specifications, for more detail and information about CodecPro's QCELP optimisation, please contact us at sales@codecpro.com.
