This Javascript app accepts a spectral analysis data file exported from Audacity (or a BPF file exported from Audiosculpt), and analyses the likely spectral peaks and their microtonal tunings.

Max. number of peaks to detect:

Peak is largest of n neighbours:

Peak must be higher than: Hz

No more than one peak per: cents

Amplitude compensation: dB per octave

Spectral Data:
(copy and paste an
Audacity .txt/Audiosculpt BPF file)

Data output
(tab-delimited, for pasting into Excel)

Music Notation:

NB: quarter-flats and quarter-sharps are encoded as double-flats and double-sharps, as Sibelius does not correctly import quartertones. Grrrr.
