Downsample waveform in gated gaussian model

[yi-fan-wang]

Standard information about the request

This is a: new feature

This change affects: inference

This change changes: scientific output

This change: follows style guidelines (See e.g. PEP8), has been proposed using the contribution guidelines

This change will: only affect the "gated_gaussian_noise" model in the inference.

Motivation

Siegel el at. showed in their recent paper the waveform should also be downsampled. So I add this feature for some tests. For nwo it's in gated gaussian model.

Contents

Add a new attribute waveform_srate in the static_params. The waveform would be generated in this sample rate and down sampled to the data's sample rate.

An example of the configuration file:

[data]
sample-rate = 1024

[static_params]
waveform_srate = 2048

With this configuration, the waveform would be generated with sampling rate 2048 Hz first and downsampled to 1024 Hz.
