diapason.core — diapason core logic¶
Core diapason code.
generate_wav(frequency, duration, rate=44100)¶
Generate a WAV file reproducing a sound at a given frequency.
frequency : float
Frequency, in hertzs, of the sound.
duration : float
Duration of the sound.
rate : int
The in-memory WAV file.
note_frequency(note, sharp=0, flat=0, octave=4, scientific=False)¶
Returns the frequency (in hertzs) associated to a given note.
All the frequencies are based on the standard concert pitch or standard piano key frequencies, meaning that A4 (using scientific picth notation) is at 440 hertzs.
note : string
Note to calculate the associated frequency from. Valid notes are characters from A to G.
octave : int
Octave position. Middle C and A440 being in the 4th octave.
sharp : int
Return a frequency higher in pitch by sharp semitones.
flat : int
Return a frequency lower in pitch by flat semitones.
scientific : bool
Use scientific pitch instead: C4 is set to 256 Hz.
The frequency (in hertzs) associated to the given note.
