If you specify 'flac:wav', MinimStreamer performs transcoding using its own internal code and there is no resampling. If you specify 'flac:wav;96' or 'flac:wav;', MinimStreamer uses the external ffmpeg program to perform transcoding and resampling is available as an option.

The problem could be caused by the use of ffmpeg (unlikely) or it could be caused by downsampling requiring more CPU resource than your DS112 can provide. You can check for the latter by opening Resource Monitor in Synology DSM and looking at the CPU consumption while transcoding is taking place. If the CPU consumption hits 100% or is very close to this figure, this means the CPU in your DS112 isn't powerful enough to do downsampling and the only way to make this work would be to buy a more powerful NAS.

Hi Simon, I'm new here. Just been catching up on reading before I posted my question and it seems you touch on my question here.

Regarding "If you specify 'flac:wav', MinimStreamer performs transcoding using its own internal code and there is no resampling. If you specify 'flac:wav;96' or 'flac:wav;', MinimStreamer uses the external ffmpeg program to perform transcoding and resampling is available as an option"

So if I want input (bit depth + sample rate) = output (bitdepth + sample rate)

but I want all my files to be transcoded to wav by minimserver,

eg: a 24/192 ALAC to be transcoded to a 24/192 WAV, should I use alac:wav ?

Another eg: a 24/96 ALAC to be transcoded 24/96 WAV, again alac:wav will do this?

Or do I need to use alac:wav24; ?

My only concern is I don't want a 16/48 ALAC to be transcoded to a 24/48 WAV if using alac:wav24; - i.e. I don't want any upsampling

Many thanks in advance :-)
