Spectral

Implementations for spectral transforms and filtering.

Core processing and analysis

spectrum(time_data[, window, scaling, nfft, ...])	Compute the power spectrum of time-domain data.
fft(time_data[, nfft])	Compute the fft of a time signal.
ifft(freq_data[, nfft])	Compute the inverst fft of a single-sided spectrum.
Filterbank(*[, bands_per_decade, ...])	Calculates spectrograms, both linear and banded.
FilterbankRoller(time_data[, duration, ...])	Rolling computation of power spectra and spectrograms, both linear and banded.
linear_to_banded(linear_spectrum, ...[, axis])	Aggregate a linear power spectrum into specified frequency bands.
nth_decade_band_edges(bands_per_decade, ...)	Find band centers and edges for Nth decade (hybrid) bands.
