"""Send audio files.

.. include:: /_includes/usable-by/users-bots.rst

Parameters:

chat_id (``int`` | ``str``):

Unique identifier (int) or username (str) of the target chat.

For your personal cloud (Saved Messages) you can simply use "me" or "self".

For a contact that exists in your Telegram address book you can use his phone number (str).

voice (``str`` | ``BinaryIO``):

Audio file to send.

Pass a file_id as string to send an audio that exists on the Telegram servers,

pass an HTTP URL as a string for Telegram to get an audio from the Internet,

pass a file path as string to upload a new audio that exists on your local machine, or

pass a binary file-like object with its attribute ".name" set for in-memory uploads.

caption (``str``, *optional*):

Voice message caption, 0-1024 characters.

parse_mode (:obj:`~pyrogram.enums.ParseMode`, *optional*):

By default, texts are parsed using both Markdown and HTML styles.

You can combine both syntaxes together.

caption_entities (List of :obj:`~pyrogram.types.MessageEntity`):

List of special entities that appear in the caption, which can be specified instead of *parse_mode*.

duration (``int``, *optional*):

Duration of the voice message in seconds.

disable_notification (``bool``, *optional*):

Sends the message silently.

Users will receive a notification with no sound.

reply_to_message_id (``int``, *optional*):

If the message is a reply, ID of the original message

schedule_date (:py:obj:`~datetime.datetime`, *optional*):

Date when the message will be automatically sent.

protect_content (``bool``, *optional*):

Protects the contents of the sent message from forwarding and saving.

reply_markup (:obj:`~pyrogram.types.InlineKeyboardMarkup` | :obj:`~pyrogram.types.ReplyKeyboardMarkup` | :obj:`~pyrogram.types.ReplyKeyboardRemove` | :obj:`~pyrogram.types.ForceReply`, *optional*):

Additional interface options. An object for an inline keyboard, custom reply keyboard,

instructions to remove reply keyboard or to force a reply from the user.

progress (``Callable``, *optional*):

Pass a callback function to view the file transmission progress.

The function must take *(current, total)* as positional arguments (look at Other Parameters below for a

detailed description) and will be called back each time a new file chunk has been successfully

transmitted.

progress_args (``tuple``, *optional*):

Extra custom arguments for the progress callback function.

You can pass anything you need to be available in the progress callback scope; for example, a Message

object or a Client instance in order to edit the message with the updated progress status.

Other Parameters:

current (``int``):

The amount of bytes transmitted so far.

total (``int``):

The total size of the file.

*args (``tuple``, *optional*):

Extra custom arguments as defined in the ``progress_args`` parameter.

You can either keep ``*args`` or add every single extra argument in your function signature.

Returns:

:obj:`~pyrogram.types.Message` | ``None``: On success, the sent voice message is returned, otherwise, in

case the upload is deliberately stopped with :meth:`~pyrogram.Client.stop_transmission`, None is returned.

Example:

.. code-block:: python

# Send voice note by uploading from local file

await app.send_voice("me", "voice.ogg")

# Add caption to the voice note

await app.send_voice("me", "voice.ogg", caption="voice caption")

# Set voice note duration

await app.send_voice("me", "voice.ogg", duration=20)
