AudioSplitter(
    audio: str,
    chunk_duration_sec: float,
    *,
    overlap_sec: float = 0.0,
    min_chunk_duration_sec: float = 0.0
)

Iterator over chunks of an audio file. The audio file is split into smaller chunks, where the duration of each chunk is determined by chunk_duration_sec. The iterator yields audio chunks as pxt.Audio, along with the start and end time of each chunk. If the input contains no audio, no chunks are yielded.

Parameters:

• chunk_duration_sec (float) –

  Audio chunk duration in seconds

• overlap_sec (float, default: 0.0 ) –

  Overlap between consecutive chunks in seconds.

• min_chunk_duration_sec (float, default: 0.0 ) –

  Drop the last chunk if it is smaller than min_chunk_duration_sec
