MinimServer2 : Best audio transcoder/resampler and transcode options

For example, you are transcoding dsf to wav24;96 but it might sound better with wav24;88 (an exact ratio of the native frequency of 352.8 kHz). Also, upsampling all wav and mp4 to 96 kHz might not be optimal.

It is possible that there could be another transcoder/resampler that provides better quality than FFmpeg/SoX but you might not be able to use it in combination with MinimServer/MinimStreamer. Instead, you might need to convert/resample your files offline.

It would be good to hear what experiences other users have had with transcoding/resampling settings.

Thanks Simon for your reply.
I'll change my transcode option even if my audio files are Flac for 99%.

Regarding stream.options, some use precision=28 (I use 33) and cutoff=0.995 (I use cheby=1). Not heard differences with different settings here.
But few customers use dither_method ... By default it set to off.

I'm interested too in any recommandations here.

So, I tested:

convOut=-af aresample=resampler=soxr:precision=33:cutoff=0.995:dither_method=triangular

AND

convOut=-af aresample=resampler=soxr:precision=33:cheby=1:dither_method=triangular
