(lsp, has_gain=True, loggain=False, fs=None, itype=0)[source]¶ LSP to LPC
Parameters: - lpc : array
LPC
- has_gain : bool, optional
Whether input LPC has gain at the index 0 or not. Default is True.
- loggain : bool, optional
If True, it’s assumed that input LPC has loggain and convert it to linear gain. Default is False.
- fs : int, optional
Sampling frequency. Default is None and unused.
- itype : int, optional
- Input LPC format
- normalized frequency (0 ~ pi)
- normalized frequency (0 ~ 0.5)
- frequency (kHz)
- frequency (Hz)
Default is 0.
Returns: - lsp : array, shape (
order + 1
) if has_gain else (order
) LPC
Raises: - ValueError
if
fs
is not specified when itype = 2 or 3. ifloggain
and nothas_gain
