Local Files

Local Roon files have some special features over streamed content:

  • You have a nice looking waveform.
  • The dynamic range of an album will be shown.
  • You can add lyrics.
  • You can expand meta data.
  • You can group tracks.
  • You can tag your tracks with ROONRADIOBAN (set to values 1 or true or yes), so the tracks will no longer be selected by Roon-Radio.
  • You can edit tracks.
  • When playing you are not dependent on a stable internet connection.

Tagging (meta data)

Roon cleans up your music library and updates the metadata associated with your music.

Although Roon has a rich metadata database, it sometimes happens, especially for less popular albums, that they can not be identified. Here it is helpful to tag these to supplement the missing data.

Software for editing meta data:

Converting files

5.1 flac to Stereo flac

ffmpeg -i /audio/5.1-input.flac -ac 2 /audio/stereo.flac

DTS wav to other lossless formats

If necessary simply replace .wav with another file format:

for file in *.wav; do name=$(echo $file | sed "s/\\.wav//g"); ffmpeg -acodec dts -i "$name".wav -vn -sn -acodec flac "$name".flac; done

Grouping tracks in Roon

This procedure is currently a bit awkward. First, all pieces that are to be grouped must be tagged with an external (not within Roon) tag editor according to the following scheme:

  • WORK: The Dark Ages/Babylon
  • PART: I. The Dark Ages
  • WORK: The Dark Ages/Babylon
  • PART: II. Babylon

In some cases the album has to be edited in Roon:

Metadata Preferences → Multi-part Composition Group → Choose Prefer File
