Bitrate and bitdepth

[vdbee]

Thanks for this very easy to use software.

Please can you give some directions on how to configure Mopidy and possibly also the server and client for a FLAC stream with higher bitrate (48kHz) and bitdepth (24bits) with a high quality resampling (default is 4, max is 10?) ?

Hi,
you have to configure the format (-s option on the server) according to the input source (it has to match the format you're feeding into the /tmp/snapfifo pipe). Default is 44100:16:2.
Also there is no resampling in Snapcast. This must happen beforehand to have a fixed sample format.
You can configure the compression ratio of FLAC with -c flac:x. This is only the compression ratio - FLAC will always be loss less.
But: currently in the Flac encoder/decoder the 16 bit and 2 channels are hard coded. So you can actually only change the sampling rate to e.g. 48000 using -s 48000:16:2.
Support for different bit depths and channels is on the road map.

Snapcast v0.7.0 now supports Hi-Res audio.
You can configure the sample format per stream or globally to e.g. 48 kHz, 24 bit, stereo:
Per stream:
-s "pipe:///tmp/snapfifo?name=Radio&sampleformat=48000:24:2"
As default:
--sampleformat 48000:24:2
