[−][src]Function aubio_sys::aubio_db_spl
pub unsafe extern "C" fn aubio_db_spl(v: *const fvec_t) -> smpl_t
compute sound pressure level (SPL) in dB
This quantity is often wrongly called 'loudness'.
This gives ten times the log10 of the average of the square amplitudes.
\param v vector to compute dB SPL from
\return level of v in dB SPL
