Digital room correction with MinimServer?

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?

Yes, by using the convOut option of the stream.transcode property. See this section (for libsoxr) and this post (for convolution).

Quote: 2) Will it handle gapless playback?

Yes, if this is supported by your control point and renderer.

Quote: 3) Can I convolve and upsample at the same time using this solution?

Yes.

Quote: 4) Can I run multiple MinimServers with different correction settings (e.g. "no correction", "living room","bedroom")

Yes, if you are using a Linux system such as Raspberry Pi and the processor has enough power to handle multiple instances running simultaneously. Each MinimServer instance must be installed in its own directory.
