aspen.sounds.click_train_pitch¶

Click train pitch

Functions

click_train_pitch([duration, interval, …])

Generate click train pitch.

Classes

ClickTrainPitch([…])

Generate click train pitch.

class aspen.sounds.click_train_pitch.ClickTrainPitch(click_train_pitch_duration=[1000], click_train_pitch_interval=[1], click_train_pitch_num_signals=1, samp_freq=16000)[source]¶

Bases: aspen.interfaces.abs_common_interface.AbsCommonInterface, aspen.interfaces.abs_sound_interface.AbsSoundInterface

Generate click train pitch.

Parameters

click_train_pitch_duration¶ (Sequence[float]) – The duration of click train pitch in millisecond. Defaults to [1000].
click_train_pitch_interval¶ (Sequence[float]) – Interval duration of clicks in millisecond. This variable determines the fundamental frequency (f0 = 1 / interval * 1000). Defaults to [1].
click_train_pitch_num_signals¶ (int) – Number of signals. If this value greater than 2, the other arguments should contain 2 types. Defaults to 1.
samp_freq¶ (int) – Sampling frequency. Defaults to 16000.

__call__()¶

Generate a specified number of signals.

Return type

List[ndarray]

Returns

Generate signals.: Output well be sequence-like object such as list, tuple and so on.

_generate_each(idx)[source]¶

Generate each signal.

Parameters: idx¶ (int) – Index of signal generation.
Return type: ndarray
Returns: Generate signal.

static add_arguments(parser)[source]¶: add arguments

classmethod load_class_kwargs(args)¶

Return the kwargs dict for class __init__ from parsed arguments

Parameters: args¶ (Namespace) – (config)argparse arguments
Return type: dict
Returns: kwargs for class __init__

aspen.sounds.click_train_pitch.click_train_pitch(duration=[1000], interval=[1], num_signals=1, samp_freq=16000)[source]¶

num_signals¶ (int) – Number of signals. If this value greater than 2, the other arguments should contain 2 types. Defaults to 1.
samp_freq¶ (int) – Sampling frequency. Defaults to 16000.

Return type

List[ndarray]

Returns

Output signals.
