Hi John,
If you are looking for more configurable audio playing, you might try out HDSDR (free software defined radio interface). On the downloads page,
https://relatedcontentdemo.kinsta.cloud/support/downloads/bb60c-bb60a-downloads/
look for the HDSDR compatibility files which will include a manual for setting up the software and the necessary files. HDSDR can interface our device and provide much more configurable audio outputs with real-time visualizations which might be useful for your task.
Regards,
A.J.
