# An audio Recorder for streamlit
#
# Description
# Audio recorder component for streamlit.
# It creates a button to start the recording and takes three arguments:
# the start button text, the stop button text, and the pause button text.
# If the pause button text is not specified, the pause button is not displayed.
#
# Parameters
# The signature of the component is:
# audiorecorder(start_prompt="Start recording", stop_prompt="Stop recording", pause_prompt="", key=None):
# The prompt parameters are self-explanatory, and the optional key parameter is used internally by streamlit 
# to properly distinguish multiple audiorecorders on the page.
#
# Return value
# The component's return value is a pydub AudioSegment.
#
# All AudioSegment methods are available, in particular you can:
# - Play the audio in the frontend with st.audio(audio.export().read())
# - Save the audio to a file with audio.export("audio.wav", format="wav")
#   JB: Waarom zie ik in mijn HF Spaces omgeving de file "audio.wav" niet terug ?
#   JB: 08-04-2024 - Mogelijk is caching al voldoende (anders file persistence)#

Львів – одне з моїх найулюбленіших міст України. Я вже відвідувала це місто п’ять разів, але хочу повертатися туди знову і знову. Львів – це історична столиця Галичини і Західної України. Це великий культурний, політичний і релігійний центр України.
Львів був заснований у середині XIII ст. князем Данилом Романовичем біля Звенигорода і названий на честь його сина, Лева. Сьогодні Львів має площу 155 км. кв. Найбільш виразна частина Львова включає проспект Шевченка і Городецьку вулицю, з безліччю громадських будинків, готелів, кафе, магазинів і банків у стилі ХІХ-ХХ ст.
Львів – дивовижне місто, яке наскрізь просякнуте п’янким ароматом кави і шоколаду. Світ візит я починаю із серця Львова – Площа ринок, потім я підіймаюся на Ратушу. Я люблю відвідувати заклади, які стали візитівкою міста такі як: Копальня кави, Майстерня шоколаду, Гасова Лямпа, Дім Легенд. Львів — єдине в Україні місто, у якому збереглися архітектурні споруди часів Ренесансу. Найбільш яскравими прикладами цього стилю служать церква Успіння і каплиця Трьох Святих. 
Основні пам'ятники міста — пам'ятник А. Міцкевичу, І. Франку, В. Стефанику, С. Бандері. Екскурсія середньовічними замками також не залишає нікого байдужим.
Неможливо передати словами всю красу і велич Львова, треба бачити це самостійно. Це старовинне місто, яке зачаровує своїми традиціями, красою та шармом.
