### `display_audio_file` (~222 tokens)

Display audio file

Display a UI for an audio file, providing the user with playback, metadata, and statistics. Use when the user specifically asks to hear or see an audio file, or when otherwise clear from context that one would be helpful.

Input parameters:

- `annotations` (object): Optional annotation lanes drawn between the waveform and spectrogram. Each lane has an optional label, optional CSS color, spans [{start,end}] in seconds, and an optional envelope ([{time,value}] wit…
- `annotationsPath` (string): Absolute path to a JSON file containing the same { lanes: [...] } structure as `annotations`. Use instead of `annotations` for large payloads. Ignored if `annotations` is also given.
- `path` (string, required): Absolute path to an audio file on the user's machine
- `playheadSeconds` (number): Optional initial playhead position in seconds (decimal)
- `region` (object): Optional initial selected/highlighted region in seconds (decimal)
