It is worth noting that when the pitch is smaller than the sub-frame size, we repeat the excitation at a period .For example, when , we use instead. In most modes, the pitch period is encoded with 7 bits in the range and the coefficients are vector-quantized using 7 bits at …the increased frequency resolution in lower sub-bands and critical sub-sampling result-ing in the minimal number of FDLP residual parameters to be transmitted. However, a higher number of sub-bands resulted in higher number of AR model parameters to be transmitted. Hence, the final bit-rates for this version of the codec were significantly
