auditok.io.BufferAudioSource

class auditok.io.BufferAudioSource(data, sampling_rate=16000, sample_width=2, channels=1)

An AudioSource that encapsulates and reads data from a memory buffer.

This class implements the Rewindable interface. :param data: audio data :type data: bytes :param sampling_rate: number of samples per second of audio data. :type sampling_rate: int, default: 16000 :param sample_width: size in bytes of one audio sample. Possible values: 1, 2 or 4. :type sample_width: int, default: 2 :param channels: number of channels of audio data. :type channels: int, default: 1

__init__(data, sampling_rate=16000, sample_width=2, channels=1)

Initialize self. See help(type(self)) for accurate signature.
