Audio record streamlit
This streamlit component allows to register an audio utterence from a user.

import streamlit as st from audio_recorder_streamlit import audio_recorder audio_bytes = audio_recorder() if audio_bytes: st.audio(audio_bytes, format="audio/wav")
You can adjust the recording parameters
energy_threshold: The energy recording sensibility above which we consider that the user is speaking. If it is a float, then this is the energy threshold used to automatically detect recording start and recording end. You can provide a tuple for specifying different threshold for recording start detection and recording end detection.
pause_threshold: The number of seconds to spend below
energy_levelto automatically stop the recording.
sample_rate: Sample rate of the recorded audio. If not provided, this will use the default sample rate (https://developer.mozilla.org/en-US/docs/Web/API/AudioContext/AudioContext).
# The recording will stop automatically # 2 sec after the utterance end audio_bytes = audio_recorder(pause_threshold=2.0, sample_rate=41_000)

Frequently Asked Question
How can I record for a fixed duration ?
You can record for a fixed duration by setting the
so that the recorder considers that you are speaking at the beginning and then
you are never speaking from this point on.
Then simply set
pause_threshold to your desired recording length.
# Records 3 seconds in any case audio_bytes = audio_recorder( energy_threshold=(-1.0, 1.0), pause_threshold=3.0, )
