| ## Args || |---|---| | `channels` | Number of input channels. | | `sampling_rate` | Sampling rate in Hertz. | | `buffer_size` | Size of the ring buffer in number of samples. |



| ## Raises || |---|---| | `ValueError` | if any of the arguments is non-positive. | | `ImportError` | if failed to import `sounddevice`. | | `OSError` | if failed to load `PortAudio`. |



| ## Attributes || |---|---| | `buffer_size` |

| | `channels` |

| | `sampling_rate` |

## Methods ### `read` [View source](https://github.com/tensorflow/tflite-support/blob/v0.4.4/tensorflow_lite_support/python/task/audio/core/audio_record.py#L108-L126) read( size: int ) -> np.ndarray Reads the latest audio data captured in the buffer.


| Args || |---|---| | `size` | Number of samples to read from the buffer. |



| Returns || |---|---| | A NumPy array containing the audio data. ||



| Raises || |---|---| | `ValueError` | Raised if `size` is larger than the buffer size. |
