audio_chunk: bytes | None = None
An audio blob containing the next segment of audio from your application, with a maximum duration of 1 second. The maximum size in bytes varies based on audio properties.
Find recommended size in Transcribing streaming best practices.
Size calculation:
Duration (s) * Sample Rate (Hz) * Number of Channels * 2 (Bytes per Sample)
For example, a 1-second chunk of 16 kHz, 2-channel, 16-bit audio would
be 1 * 16000 * 2 * 2 = 64000 bytes.
For 8 kHz, 1-channel, 16-bit audio, a 1-second chunk would be
1 * 8000 * 1 * 2 = 16000 bytes.
