Spectrum: To Ltas (1-to-1)

A command for converting each selected Spectrum object into an Ltas object without loss of frequency resolution.

## Algorithm

Each band bi in the Ltas is computed from a single frequency sample si in the Spectrum as follows:

bi = 2 ((re (si))2 + (im (si))2) / 4.0·10-10

If the original Spectrum is expressible in Pa / Hz (sound pressure in air), the Ltas values are in "dB/Hz" relative to the auditory threshold at 1000 Hz (2·10-5 Pa).
