Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
A quick google search gave me this result: https://github.com/AndreMiras/pycaw/blob/v20160929/examples/volume_by_process_example.py What you want to achieve looks achievable in Windows. For Mac it should be possible as well, but I haven't looked it up yet.
