`st.audio` does not take a numpy array?

Question

The streamlit docs (https://docs.streamlit.io/en/stable/api.html#streamlit.audio) state that streamlit.audio can take a numpy ndarray containing raw sample data and display an audio player. I tried this as follows on a local host:

import streamlit as st
import soundfile
data, sr = soundfile.read('test.wav')
st.audio(data)

It successfully displays an audio player and throws no errors, however there is no available sound.

Am I doing anything wrong or are the docs incorrect?

Is your code correct? It appears you unpack data and sr to variables, but then you pass audio to the np.array function. Where does audio come from, or should that be data instead?

i made a typo. Please see edit. Also I am not passing audio to np.array so I a not sure what you are referring to there.... – user32882 Jun 17 '21 at 02:32
I'm referring to this line, `audio` is not defined in your code snippet `st.audio(np.array([audio]))` – Randy Zwitch Jun 17 '21 at 14:38
Oh yes, that is another typo. My bad. It should simply be `st.audio(data)` – user32882 Jun 17 '21 at 14:43
