# AudioSplitter

# class pixeltable.iterators.AudioSplitter
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.
Args:
chunk\_duration\_sec: Audio chunk duration in seconds
overlap\_sec: Overlap between consecutive chunks in seconds.
min\_chunk\_duration\_sec: Drop the last chunk if it is smaller than min\_chunk\_duration\_sec
## method build\_chunks()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
build_chunks(
start_time_sec: float,
total_duration_sec: float,
chunk_duration_sec: float,
overlap_sec: float,
min_chunk_duration_sec: float
) -> list[tuple[float, float]]
```
## method close()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
close() -> None
```
Close the iterator and release all resources
## method create()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
create(**kwargs: Any) -> tuple[type[ComponentIterator], dict[str, Any]]
```
## method input\_schema()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
input_schema() -> dict[str, pixeltable.type_system.ColumnType]
```
Provide the Pixeltable types of the init() parameters
The keys need to match the names of the init() parameters. This is equivalent to the parameters\_types
parameter of the @function decorator.
## method output\_schema()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
output_schema(
*args: Any,
**kwargs: Any
) -> tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]
```
Specify the dictionary returned by next() and a list of unstored column names
**Returns:**
* `tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]`: a dictionary which is turned into a list of columns in the output table
a list of unstored column names
## method set\_pos()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
set_pos(pos: int) -> None
```
Set the iterator position to pos
