stream.transcode

Is there any way to provide optimal stream.trancode settings per device?

I am having a Linn Klimax Exact DMS (2013 Version) in my living room which has the following specs: 192k/24bit Analogue to Digital convertion for Analogue input

With this I was adding the following stream.transcode setting in MinimServer:
flac:wav, flac(16;44):wav24;176, flac(24;44):wav;176, flac(24;48):wav;192, flac(24;88):wav;176, flac(24;96):wav;192, flac(24;176):wav, flac(24;192):wav, mp3:wav24, alac:wav24, mp4:wav24

Here are the stream.options: convOut=-af aresample=resampler=soxr:precision=28

That seems to be ideal for the Linn device. My new NAIM Uniti Atom has the following specs:
WAV - up to 32bits/384kHz
FLAC - up to 24bit/384kHz
ALAC - up to 24bit/384kHz
MP3 - up to 48kHz, 320kbit (16 bit)
M4A - up to 48kHz, 320kbit (16 bit)

What is the most intelligent solution to provide ideal sound per device?

1) There is no "optimal". Higher resolution isn't always better. It depends on how the DAC works and also on your room and your ears.
2) MinimServer doesn't know what renderer you are using. Only the control point knows this.
3) There is a UPnP protocol for a renderer to declare what formats and resolutions it supports but many renderers don't implement this correctly.

I suggest you work out what is optimal for your Linn and save the settings in a MinimServer profile named Linn. It sounds like you already have these settings. Do the same for your Naim and save the settings in a MinimServer profile named Naim. If the Linn and Naim settings are different, you can switch manually between the profiles when you change renderer.

Thanks a lot, Simon. That's a great solution, just what I was hoping for.

Question for the community: does anyone already have the ideal stream.transcode and stream.options settings for the NAIM Uniti Atom?
