Component Setup - step by step
1. Import and install relevant libraries to your Python project.
import os
import numpy as np
import streamlit as st
from io import BytesIO
import streamlit.components.v1 as components
2. Add the folder /st_audiorec to the top level directory of your project.
3. Add the file st_custom_components.py to your project wherever you like.
4. Import the function st_audiorec() to your main streamlit application code.
from st_custom_components import st_audiorec
5. Add an instance of the audio recorder component to your streamlit app's code.
wav_audio_data = st_audiorec()
if wav_audio_data is not None:
# display audio data as received on the backend
st.audio(wav_audio_data, format='audio/wav')
# INFO: by calling the function an instance of the audio recorder is created
# INFO: once a recording is completed, audio data will be saved to wav_audio_data
6. Enjoy recording audio inside your streamlit app!
