cutcutcodec.core.filter.audio.delay

Allow to temporarily translate an audio sequence.

Classes

FilterAudioDelay(in_streams, delay)

Change the beginning time of a stream.

Details

class cutcutcodec.core.filter.audio.delay.FilterAudioDelay(in_streams: Iterable[Stream], delay: Real)[source]

Change the beginning time of a stream.

Attributes

delayFraction: The delay append to the original beginning time of the stream (readonly). a positive value indicates that the output flow is later than the input flow.

Examples

>>> from cutcutcodec.core.filter.audio.delay import FilterAudioDelay
>>> from cutcutcodec.core.generation.audio.noise import GeneratorAudioNoise
>>>
>>> (s_base_audio,) = GeneratorAudioNoise(0).out_streams
>>> (s_trans_audio,) = FilterAudioDelay([s_base_audio], 10).out_streams
>>>
>>> (s_base_audio.snapshot(0) == s_trans_audio.snapshot(10)).all()
tensor(True)
>>> (s_base_audio.snapshot(10) == s_trans_audio.snapshot(10)).all()
tensor(False)
>>>

Initialise and create the class.

Parameters

in_streamstyping.Iterable[Stream]: Transmitted to cutcutcodec.core.classes.filter.Filter.
delaynumbers.Real: The temporal translation value to apply at the output audio stream.
