Power spectral density

Power spectral density tools.

Main routines

area(spec)	Compute the area under a PSD random specification.
interp(spec, freq[, linear])	Interpolate values on a PSD specification (or analysis curve).
rescale(P, F[, n_oct, freq, extendends, frange])	Convert PSD from one frequency scale to another.
spl(x, sr[, nperseg, overlap, window, ...])	Sound pressure level estimation using PSD.
psd2time(spec, fstart, fstop, *[, ppc, df, ...])	Generate a 'random' time domain signal given a PSD specification.
psdmod(sig, sr[, nperseg, timeslice, ...])	Modified method for PSD estimation via FFT.

Utility routines

get_freq_oct(n[, frange, exact, trim, anchor])	Get frequency vector on an octave scale.
proc_psd_spec(spec)	Process PSD specification for other routines
