Linear Prediction Analysis Functions

These functions perform LPC analysis, LSP coding (quantization) and decoding, as well as transformation between LPC and LSF coefficients.

• AutoCorr_G723
  Estimates the autocorrelation of a vector.
• AutoCorr_NormE_G723
  Estimates normal autocorrelation of a vector.
• LevinsonDurbin_G723
  Calculates the LP coefficients from the autocorrelation coefficients.
• LPCToLSF_G723
  Converts LP coefficients to LSF coefficients.
• LSFToLPC_G723
  Converts LSF coefficients to the LP coefficients.
• LSFDecode_G723
  Performs inverse quantization of LSFs.
• LSFQuant_G723
