auditok.io.BufferAudioSource

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

An AudioSource that reads audio data from a memory buffer.

This class implements the Rewindable interface, allowing audio data stored in a buffer to be read with support for rewinding and position control.

Parameters:
  • data (bytes) – The audio data stored in a memory buffer.

  • sampling_rate (int, optional, default=16000) – The number of samples per second of audio data.

  • sample_width (int, optional, default=2) – The size in bytes of one audio sample. Accepted values are 1, 2, or 4.

  • channels (int, optional, default=1) – The number of audio channels.

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