Quick start

The “quick start” code below demonstrates a basic pipeline for downloading an audio file, loading it into OpenSoundscape, and creating a spectrogram from it

Import needed classes

Import the Audio and Spectrogram classes from OpenSoundscape.

(For more information about Python imports, review this article.)

# Import Audio and Spectrogram classes from OpenSoundscape
from opensoundscape import Audio, Spectrogram

#other utilities
from pathlib import Path

Get an example audio file

Here we download an example birdsong soundscape recorded by an AudioMoth autonomous recorder in Pennsylvania, USA.

audio_object=Audio.from_url('https://tinyurl.com/birds60s')
# or load a local file:
# a = Audio.from_file('/local/file/path')
