LPC
standard mode | Spectral category
Inputs
- frame (vector_real) - the input audio frame
Outputs
- lpc (vector_real) - the LPC coefficients
- reflection (vector_real) - the reflection coefficients
Parameters
- order (integer ∈ [2, ∞), default = 10) :
- the order of the LPC analysis (typically [8,14])
- sampleRate (real ∈ (0, ∞), default = 44100) :
- the sampling rate of the audio signal [Hz]
- type (string ∈ {regular, warped}, default = regular) :
- the type of LPC (regular or warped)
Description
This algorithm computes Linear Predictive Coefficients and associated reflection coefficients of a signal.
An exception is thrown if the "order" provided is larger than the size of the input signal.
