  **Bases:** [Task\[dict\]](/nemo-curator/nemo_curator/tasks/tasks#nemo_curator-tasks-tasks-Task)

  A single audio manifest entry.

  Represents one line from a JSONL manifest file (e.g. one audio file
  with its metadata).  `data` is always a single `dict`, never a list.

  Matches the `VideoTask` naming convention used by the video modality.

  **Parameters:**

  <ParamField path="data" type="dict" default="_AttrDict()">
    Manifest entry dict (e.g. `&#123;"audio_filepath": "...", "text": "..."&#125;`).
  </ParamField>

  <ParamField path="filepath_key" type="str | None" default="None">
    Optional key whose value is validated as an existing path.
  </ParamField>

  <ParamField path="data" type="dict = field(default_factory=_AttrDict)" />

  <ParamField path="dataset_name" type="str = ''" />

  <ParamField path="filepath_key" type="str | None = None" />

  <ParamField path="num_items" type="int" />

  <ParamField path="task_id" type="str = ''" />
