joal | Java Binding for the OpenAL API

I'm using maven to import the jogamp dependencies.

Here is the pom.xml content :

I am running some RFM analysis on my data in Python and have adapted Joal Correia's github code (below), which outputs the results to a CSV, to also add the results to a dataframe then publish this to a BigQuery table.

It works, but I am missing the first column of my data in BigQuery, the 'customer' id, which is the only string in my results. The column is in the .csv, and in the dataframe in python, just not in the BQ results, can anyone tell me where I am losing this?

Note: I have removed most of the RFM code to de-cluttered this post, the lines below show my additions.

UPDATE: I ran print(results.keys()) and I do not see 'customers' in this list, is this related to it not being visible in the export?

I need to play a large audio file and while playing mark beginning and and of many places in that file (one audio record contains many question-answer pairs, so I am parsing these pairs manually while listening). Then I need to get a separate audio file which contains only part of original audio file (between I pressed startClip and endClip). So one audiofile will be marked in this way and cut into multiple files (maybe some of its parts will be left out and won't be part of any resulting files).

File format is any, I can convert my original WMA to anything (JavaFX 8 has no support for WMA).

I cannot find any ways how to do it. Seems standard API doesn't help: JavaFX sound api: [Package javafx.scene.media][1]

I also learned about some sound frameworks, but can't tell they help:
