What: A standalone Sonic Analysis app that can run on powerful computers to reduce the time required to analyze large libraries.
Why: Many people run their Plex server on fairly underpowered hardware (NAS, NUC, etc), but still have a more powerful computer. Creating a standalone app that talks to your Plex server locally, does the analysis, and sends the results back for writing to the database would speed this process up immensely.
Alternative/Bonus Idea: As Plex is using Tensorflow under the hood to do the conversions, perhaps freeze the graph and export to a tflite file then allow Plex to be passed hardware TPU devices like the Google Coral into the server. Many tech-aware users will have one of these that could be utilised for this purpose.
