Digital room correction with MinimServer?

[dejwi]

Hi,

I'm all about best possible audio reproduction. In my own system I'm using a PC with specially designed FIR filters (drivers linearization, room correction, phase & timing correction, etc.) and upsampling engine. I performed these kind of correction for several systems with stunning results. I know it's a big word, but it's really making a difference.
The problem is that my friends don't want to play music from PC or have a PC in their audio chain (power consumption, usability, etc.). So I was looking for a solution to bring all the goodness of digital correction into their existing setups. That's when I stumbled upon MinimServer.

The goal:
Access digitally corrected files through UPnP. Source files are untouched.

Idea:
• Use Raspberry Pi 3
• Transcode files on the fly (from NAS or attached HDD) using MinimServer + MinimStreamer.
• Use libsoxr for convolution and upsampling (VHQ Linear Phase)

Questions that bothers me at the moment:
1) Is that scenario possible?
2) Will it handle gapless playback?
3) Can I convolve and upsample at the same time using this solution?
4) Can I run multiple MinimServers with different correction settings (e.g. "no correction", "living room","bedroom")

Any feedback is greatly appreciated.
