ippStsLPCCalcErr
Linear predictive coding estimates a filter that models the spectral envelope of a speech signal. This status indicates that IPP could not evaluate the LPC coefficients from the supplied analysis data.
Typical causes are unstable autocorrelation input, insufficient signal energy, incompatible order or corrupted frame data. The failure is in speech-analysis mathematics, not in the encoded packet syntax alone.
Check these details
- LPC order, frame length and windowed input samples.
- Autocorrelation values and whether the frame is silent or degenerate.
- Codec mode expectations for the current speech frame.
