# 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)#

from audiorecorder import audiorecorder

st.title("Audio Recorder")
# audiorecorder(start_prompt="Start recording", stop_prompt="Stop recording", pause_prompt="", key=None):

if len(audio) > 0:
    # To play audio in frontend:
    st.audio(audio.export().read())  

    # To save audio to a file, use pydub export method:
    audio.export("audio.wav", format="wav")

    # To get audio properties, use pydub AudioSegment properties:
    st.write(f"Frame rate: {audio.frame_rate}, Frame width: {audio.frame_width}, Duration: {audio.duration_seconds} seconds")
