Function signature[source]

st.audio(data, format="audio/wav", start_time=0, *, sample_rate=None)


data (str, bytes, BytesIO, numpy.ndarray, or file opened with)

io.open(). Raw audio data, filename, or a URL pointing to the file to load. Raw data formats must include all necessary file headers to match the file format specified via format. If data is a numpy array, it must either be a 1D array of the waveform or a 2D array of shape (num_channels, num_samples) with waveforms for all channels. See the default channel order at http://msdn.microsoft.com/en-us/library/windows/hardware/dn653308(v=vs.85).aspx

format (str)

The mime type for the audio file. Defaults to 'audio/wav'. See https://tools.ietf.org/html/rfc4281 for more info.

start_time (int)

The time from which this element should start playing.

sample_rate (int or None)

The sample rate of the audio data in samples per second. Only required if data is a numpy array.


import streamlit as st
import numpy as np

audio_file = open('myaudio.ogg', 'rb')
audio_bytes = audio_file.read()

st.audio(audio_bytes, format='audio/ogg')

sample_rate = 44100  # 44100 samples per second
seconds = 2  # Note duration of 2 seconds
frequency_la = 440  # Our played note will be 440 Hz
# Generate array with seconds*sample_rate steps, ranging between 0 and seconds
t = np.linspace(0, seconds, seconds * sample_rate, False)
# Generate a 440 Hz sine wave
note_la = np.sin(frequency_la * t * 2 * np.pi)

st.audio(note_la, sample_rate=sample_rate)
