A note with a pitch transition (a glissando) and a vibrato.

Parameters:

start_freqscalar

The starting frequency.

end_freqscalar

The final frequency.

durationscalar

The duration of the sound in seconds.

vibrato_freqscalar

The frequency of the vibrato oscillations in Hertz.

max_pitch_devscalar

The maximum deviation of pitch of the vibrato in semitones.

alphascalar

An index to begin the transitions faster or slower. If alpha != 1, the transition is not of linear pitch.

alpha_vibratoscalar

An index to distort the pitch deviation of the vibrato.

waveform_tablearray_like

The table with the waveform to synthesize the sound.

vibrato_waveform_tablearray_like

The table with the waveform for the vibrato oscillatory pattern.

number_of_samplesinteger

The number of samples of the sound. If supplied, d is not used.

sample_rateinteger

The sample rate.

Returns:

sndarray

A numpy array where each value is a PCM sample of the sound.

See also

P

A glissando.

V

A musical note with an oscillation of pitch.

N

A basic musical note without vibrato.

T

A tremolo, an oscillation of loudness.

F

Fade in and out.

L

A transition of loudness.
