librosa.hz_to_svara_h
- librosa.hz_to_svara_h(frequencies, *, Sa, abbr=True, octave=True, unicode=True)[source]
Convert frequencies (in Hz) to Hindustani svara
Note that this conversion assumes 12-tone equal temperament.
- Parameters:
- frequenciespositive number or np.ndarray
The frequencies (in Hz) to convert
- Sapositive number
Frequency (in Hz) of the reference Sa.
- abbrbool
If True (default) return abbreviated names (‘S’, ‘r’, ‘R’, ‘g’, ‘G’, …)
If False, return long-form names (‘Sa’, ‘re’, ‘Re’, ‘ga’, ‘Ga’, …)
- octavebool
If True, decorate svara in neighboring octaves with over- or under-dots.
If False, ignore octave height information.
- unicodebool
If True, use unicode symbols to decorate octave information.
If False, use low-order ASCII (’ and ,) for octave decorations.
This only takes effect if octave=True.
- Returns:
- svarastr or np.ndarray of str
The svara corresponding to the given frequency/frequencies
Examples
Convert Sa in three octaves:
>>> librosa.hz_to_svara_h([261/2, 261, 261*2], Sa=261) ['Ṣ', 'S', 'Ṡ']
Convert one octave worth of frequencies with full names:
>>> freqs = librosa.cqt_frequencies(n_bins=12, fmin=261) >>> librosa.hz_to_svara_h(freqs, Sa=freqs[0], abbr=False) ['Sa', 're', 'Re', 'ga', 'Ga', 'ma', 'Ma', 'Pa', 'dha', 'Dha', 'ni', 'Ni']
