The function based interface provides most of the functions that are availible as methods of the :func:`Signal` and also some that are not directly availible through the :func:`Signal` class.
.. automodule:: audiotools
:members: generate_tone, generate_noise, set_dbspl, calc_dbspl,
set_dbfs, calc_dbfs, crest_factor, zeropad,
gaussian_fade_window, cosine_fade_window,
cos_amp_modulator, shift_signal, generate_uncorr_noise,
calc_coherence, schroeder_phase, phon_to_dbspl,
time2phase, phase2time, nsamples, lowpass
Individual filter can either be applied by directly calling the respective filter functions such as :func:`filter.gammatone` or by using the unified interfaces for :func:`filter.bandpass`, :func:`filter.lowpass` and :func:`filter.highpass` filters. When using the unified interface, all additional arguments are passed to the respective filter functions.
.. automodule:: audiotools.filter
:members: bandpass, lowpass, highpass, gammatone, butterworth, brickwall
Filterbanks are created using the :func:`create_filterbank` command
.. automodule:: audiotools.filter
:members: create_filterbank
