process_file(path: PathLike | str, sr: float | None = None) → ndarray

Process individual audio file.

Parameters:

path: pathlike or str: The path to an audio file.
sr: float, optional: Target sample rate. If not given, then each audio file is loaded with its native sample rate. Otherwise audio data is resampled to this sample rate.

Returns:

process_files(paths: Iterable[str | PathLike], batch_size: int, sr: float | None = None) → Iterable[ndarray]

Process a set of files.

Parameters:

paths: iterables of path or iterable of str: Paths to audio files.
batch_size: int: Batch size. Note that if batch_size != 1 then either sr must be given, or all files must have the same native sample rate.
sr: float, optional: Target sample rate. If not given, then each audio file is loaded with its native sample rate. Otherwise audio data is resampled to this sample rate.

Returns:
