lsp2sp(lsp, fftlen=256, has_gain=True, loggain=False, fs=None, itype=0)¶
LSP to spectrum
- lsp : array
- fftlen : int, optional
- 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.
- sp : array, shape
