Audio Analysis from S3

KNIME Analytics Platform

Hi!
Is there a possibility to get audio files properties like size and duration of files from S3?

I know that there are the Audio Data Extractor and Acoustic Feature Extractor but they seem to work only with the local disk, not with S3.

I tried using Amazon Legacy Connection and the Legacy Amazon S3 File Picker to get the S3 URL and then use the URL To Audio node, but it doesn’t want to work.

How do I sort this without actually downloading the files to local?

Thank you,
Maia

Hi
I am not aware of a Node that could do that (maybe someone else is?) but you could try using python script node. boto3 package to connect to your s3 storage and librosa library to read the file details.
