auditok.io.PyAudioSource

class auditok.io.PyAudioSource(sampling_rate=16000, sample_width=2, channels=1, frames_per_buffer=1024, input_device_index=None)

An AudioSource class for reading data from a built-in microphone using PyAudio.

This class leverages PyAudio (https://people.csail.mit.edu/hubert/pyaudio/) to capture audio data directly from a microphone.

Parameters:

• 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 each audio sample. Accepted values are 1, 2, or 4.

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

• frames_per_buffer (int, optional, default=1024) – The number of frames per buffer, as specified by PyAudio.

• input_device_index (int or None, optional, default=None) – The PyAudio index of the audio device to read from. If None, the default audio device is used.

__init__(sampling_rate=16000, sample_width=2, channels=1, frames_per_buffer=1024, input_device_index=None)
