I have recently upgraded to a Plex Pass and Plexamp was one of the deciding factors on my decision to upgrade. It seems I should have done a bit more research as most of the functionality of Plexamp relies on their " sophisticated sonic technology." which isn’t available on a Pi based PMS.
Are there any workarounds to get more out of Plexamp in these circumstances or is it only meant for more powerful servers?
A lot of Plexamp’s best features are built on top of the server’s sonic analysis, that’s right. The analysis process is quite processor intensive, taking weeks to complete even on powerful systems (depending on the size of the library).
For the reasons above, we don’t support ARM servers for this process, aside from on Apple Silicon hardware. I’m not aware of any workarounds, unfortunately.
For alternative server hardware that’s capable of performing sonic analysis, Intel NUCs are a popular small form-factor option, or x86_64 NAS devices are another.
Would it not be possible to allow the sonic analysis to be carrieď out by a seperate computer.
The main media server tasks could be carried out by the PMS device, in my case a Raspberry Pi but processor intensive, one off, tasks could be carried out by another device on the network.
My PMS is headless and I access it through a windows machine, is there a good reason why the windows machine could not carry out the sonic analysis and pass the data to the server.
