music.note

music.note(freq=220, duration=2, waveform_table=array([-1., -0.99975586, -0.99951172, ..., -0.99926758, -0.99951172, -0.99975586], shape=(16384,)), number_of_samples=0, sample_rate=44100)

Synthesize a basic musical note.

Parameters:

freqscalar

The frequency of the note in Hertz.

durationscalar

The duration of the note in seconds.

waveform_tablearray_like

The table with the waveform to synthesize the sound.

number_of_samplesinteger

The number of samples in the sound. If not 0, duration is ignored.

sample_rateinteger

The sample rate.

Returns:

resultndarray

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

Parameters:

• freq (float)

• duration (float)

• waveform_table (ArrayLike)

• number_of_samples (int)

• sample_rate (int)

Return type:

NDArray[float64]

See also

note_with_vibrato

A note with vibrato.

tremolo

A tremolo envelope.

Notes

In the MASS framework implementation, for a sound with a vibrato (or FM) to be synthesized using LUT, the vibrato pattern is considered when performing the lookup calculations.

The tremolo and AM patterns are implemented as separate amplitude envelopes.
