consideration, the save file path is included in the message.context, putting this in a thread will remove that info from downstream clients. eg, something could be parsing the audio for speaker recognition or something

so using a thread should probably be a flag with this documented, it shouldnt be an issue most of time and can even default to using a thread. in hivemind context this info is useless too as the file path doesnt exist in both sides of hivemind connection

Saving on NVMe drive is pretty transparent.
