+### Audio File type specific transcoding options within Navidrome
+
+In some situations you may wish to have different 'Players' within Navidrome so that you can configure different transcoding options depending on the file type.  For example if you have a mixture of flac file formats where not all are supported by sonos ![See issue #52](https://github.com/simojenki/bonob/issues/52) & ![Sonos supported audio formats](https://developer.sonos.com/build/content-service-add-features/supported-audio-formats/)
+
+In this case you could set;
+
+```bash
+BONOB_NAVIDROME_CUSTOM_CLIENTS="audio/flac"
 ```
+
+This would result in 2 players in Navidrome, one called 'bonob', the other called 'bonob+audio/flac'.  You could then configure a custom flac transcoder in Navidrome that re-samples the flacs to a sonos supported format, ie ![Using something like this](https://stackoverflow.com/questions/41420391/ffmpeg-flac-24-bit-96khz-to-16-bit-48khz);

+```bash
