Types ¶
type PulseExcite ¶
type PulseExcite struct {
SampleRate int
FrameShift int
UseGauss bool
// contains filtered or unexported fields
}
PulseExcite represents generating excitation signals. if UseGauss is set to true, gaussian random samples are generated for non-voice segments, pseudo random samples otherwise.
func NewPulseExcite ¶
func NewPulseExcite(sampleRate, frameShift int) *PulseExcite
NewPulseExcite returns its instance with sample rate and framshift.
func (*PulseExcite) Generate ¶
func (e *PulseExcite) Generate(f0Sequence []float64) []float64
Gerenate generates an excitation signal from f0 sequence. If the unvoiced segment is detected (segment of zero f0), this generates gaussian or pseudo random samples, f0-dependent excitation otherwise.
func (*PulseExcite) GenerateOneFrame ¶
func (e *PulseExcite) GenerateOneFrame(f01, f02 float64) []float64
GenerateOneFrame generates an excitation signal from successive two f0. If the given f0 have zero value(s), GenerateOneFrame generates random samples, f0-dependent excitation otherwise.
