PyannoteViewer

Initialization

name	type	default	description
value	str | pathlib.Path | tuple[int, numpy.ndarray] | Callable | None	None	A path, URL, or [sample_rate, numpy array] tuple (sample rate in Hz, audio data as a float or int numpy array) for the default value that SourceViewer component is going to take. If callable, the function will be called whenever the app loads to set the initial value of the component.
sources	list["upload" | "microphone"] | None	None	A list of sources permitted for audio. "upload" creates a box where user can drop an audio file, "microphone" creates a microphone input. The first element in the list will be used as the default source. If None, defaults to ["upload", "microphone"], or ["microphone"] if `streaming` is True.
type	"numpy" | "filepath"	"numpy"	The format the audio file is converted to before being passed into the prediction function. "numpy" converts the audio to a tuple consisting of: (int sample rate, numpy.array for the data), "filepath" passes a str path to a temporary file containing the audio.
label	str | None	None	The label for this component. Appears above the component and is also used as the header if there are a table of examples for this component. If None and used in a `gr.Interface`, the label will be the name of the parameter this component is assigned to.
every	float | None	None	If `value` is a callable, run the function 'every' number of seconds while the client connection is open. Has no effect otherwise. The event can be accessed (e.g. to cancel it) via this component's .load_event attribute.
show_label	bool | None	None	if True, will display label.
container	bool	True	If True, will place the component in a container - providing some extra padding around the border.
scale	int | None	None	Relative width compared to adjacent Components in a Row. For example, if Component A has scale=2, and Component B has scale=1, A will be twice as wide as B. Should be an integer.
min_width	int	160	Minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first.
interactive	bool | None	None	If True, will allow users to upload and edit an audio file. If False, can only be used to play audio. If not provided, this is inferred based on whether the component is used as an input or output.
visible	bool	True	If False, component will be hidden.
streaming	bool	False	If set to True when used in a `live` interface as an input, will automatically stream webcam feed. When used set as an output, takes audio chunks yield from the backend and combines them into one streaming audio output.
elem_id	str | None	None	An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles.
elem_classes	list[str] | str | None	None	An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles.
render	bool	True	If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later.
format	"wav" | "mp3"	"wav"	The file format to save audio files. Either 'wav' or 'mp3'. wav files are lossless but will tend to be larger files. mp3 files tend to be smaller. Default is wav. Applies both when this component is used as an input (when `type` is "format") and when this component is used as an output.
autoplay	bool	False	Whether to automatically play the audio when the component is used as an output. Note: browsers will not autoplay audio files if the user has not interacted with the page yet.
show_download_button	bool | None	None	If True, will show a download button in the corner of the component for saving audio. If False, icon does not appear. By default, it will be True for output components and False for input components.
show_share_button	bool | None	None	If True, will show a share icon in the corner of the component that allows user to share outputs to Hugging Face Spaces Discussions. If False, icon does not appear. If set to None (default behavior), then the icon appears if this Gradio app is launched on Spaces, but not otherwise.
editable	bool	True	If True, allows users to manipulate the audio file if the component is interactive. Defaults to True.
min_length	int | None	None	The minimum length of audio (in seconds) that the user can pass into the prediction function. If None, there is no minimum length.
max_length	int | None	None	The maximum length of audio (in seconds) that the user can pass into the prediction function. If None, there is no maximum length.
waveform_options	WaveformOptions | dict | None	None	A dictionary of options for the waveform display. Options include: waveform_color (str), waveform_progress_color (str), show_controls (bool), skip_length (int), trim_region_color (str). Default is None, which uses the default values for these options.

Events

name	description
stream	This listener is triggered when the user streams the PyannoteViewer.
change	Triggered when the value of the PyannoteViewer changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See .input() for a listener that is only triggered by user input.
clear	This listener is triggered when the user clears the PyannoteViewer using the X button for the component.
play	This listener is triggered when the user plays the media in the PyannoteViewer.
pause	This listener is triggered when the media in the PyannoteViewer stops for any reason.
stop	This listener is triggered when the user reaches the end of the media playing in the PyannoteViewer.
start_recording	This listener is triggered when the user starts recording with the PyannoteViewer.
pause_recording	This listener is triggered when the user pauses recording with the PyannoteViewer.
stop_recording	This listener is triggered when the user stops recording with the PyannoteViewer.
upload	This listener is triggered when the user uploads a file into the PyannoteViewer.

User function

The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).

• When used as an Input, the component only impacts the input signature of the user function.
• When used as an output, the component only impacts the return signature of the user function.

The code snippet below is accurate in cases where the component is used as both an input and an output.

• As output: Is passed, passes audio as one of these formats (depending on type): a str filepath, or tuple of (sample rate in Hz, audio data as numpy array). If the latter, the audio data is a 16-bit int array whose values range from -32768 to 32767 and shape of the audio data array is (samples,) for mono audio or (samples, channels) for multi-channel audio.
• As input: Should return, expects audio data in any of these formats: a str or pathlib.Path filepath or URL to an audio file, or a bytes object (recommended for streaming), or a tuple of (sample rate in Hz, audio data as numpy array). Note: if audio is supplied as a numpy array, the audio will be normalized by its peak value to avoid distortion or clipping in the resulting audio.
