## SETTINGS:
# General:
save_path = '../data/processed/white_noise'
stages = ['raw', 'filt', 'env', 'log', 'inv', 'conv', 'bi', 'feat']
sds = [1]
dur = 60
# Interactivity:
reload_saved = False
# Processing:
rate = 44100.0
env_rate = 44100.0
feat_rate = 44100.0
sigmas = [0.001, 0.002, 0.004, 0.008, 0.016, 0.032]
types = [1, -1, 2, -2, 3, -3, 4, -4, 5, -5,
6, -6, 7, -7, 8, -8, 9, -9, 10, -10]
config = configuration(env_rate, feat_rate, types=types, sigmas=sigmas)
config.update({
'rate_ratio': None,
'env_fcut': 250,
'db_ref': 1,
'inv_fcut': 5,
'feat_thresh': np.load('../data/kernel_thresholds.npy') * 0.2,
'feat_fcut': 0.5,
'label_channels': 0,
'label_thresh': 0.5,
})
## PREPARATION:
n_samples = int(dur * env_rate)
rng = np.random.default_rng()
# PROCESSING:
for sd in sds:
print('Processing: SD =', sd)
# Generate white noise signal:
noise = rng.normal(loc=0, scale=sd, size=n_samples)
# Fetch and store representations:
save = None if save_path is None else save_path + f'_sd-{sd}.npz'
process_signal(config, stages, signal=noise, rate=rate, save=save)
# Cross-control:
if reload_saved:
data, params = load_data(save, stages, ['songs', 'noise'])
embed()
print('Done.')
