If there is a match, all items in the directory are marked as compilations.Changing this setting only takes effect after a rescan. **Default:** unset ```conf compilations = { "/Compilations" } ``` - `compilation_artist` - Artist name of compilation albums. **Note:** Compilations usually have multiple artists, and sometimes may have no album artist. If you don't want every artist to be listed, you can set a single name which will be used for all compilation tracks without an album artist, and for all tracks in the compilation directories. Changing this setting only takes effect after a rescan. **Default:** unset ```conf compilation_artist = "" ``` - `hide_singles` - Flag to indicate whether or not single albums must be hidden. **Note:** If your album and artist lists are cluttered, you can choose to hide albums and artists with only one track. The tracks will still be visible in other lists, e.g., tracks and playlists. This setting currently only works with some remotes. **Default:** `false` ```conf hide_singles = ` ``` - `radio_playlists` - Flag to show internet streams in normal playlists. **Note:** By default the internet streams are shown in the "Radio" library, like iTunes does. However, some clients (like TunesRemote+) won't show the "Radio" library. **Default:** `false` ```conf radio_playlists = ``` - `name_library` - Name of the default playlist _Library_. **Note:** This is a default playlist, which can be renamed with this setting. **Default:** `"Library"` ```conf name_library = "" ``` - `name_music` - Name of the default playlist _Music_. **Note:** This is a default playlist, which can be renamed with this setting. **Default:** `"Music"` ```conf name_music = "" ``` - `name_movies` - Name of the default playlist _Movies_. **Note:** This is a default playlist, which can be renamed with this setting. **Default:** `"Movies"` ```conf name_movies = "" ``` - `name_tvshows` - Name of the default playlist _TV Shows_. **Note:** This is a default playlist, which can be renamed with this setting. **Default:** `"TV Shows"` ```conf name_tvshows = "" ``` - `name_podcasts` - Name of the default playlist _Podcasts_. **Note:** This is a default playlist, which can be renamed with this setting. **Default:** `"Podcasts"` ```conf name_podcasts = "" ``` - `name_audiobooks` - Name of the default playlist _Audiobooks_. **Note:** This is a default playlist, which can be renamed with this setting. **Default:** `"Audiobooks"` ```conf name_audiobooks = "" ``` - `name_radio` - Name of the default playlist _Radio_. **Note:** This is a default playlist, which can be renamed with this setting. **Default:** `"Radio"` ```conf name_radio = "" ``` - `name_unknown_title` - Name of tracks having an undefined title. **Default:** `"Unknown title"` ```conf name_unknown_title = "" ``` - `name_unknown_artist` - Name of artist having an undefined name. **Default:** `"Unknown artist"` ```conf name_unknown_artist = "" ``` - `name_unknown_album` - Name of album having an undefined title. **Default:** `"Unknown album"` ```conf name_unknown_album = "" ``` - `name_unknown_genre` - Name of genre having an undefined name. **Default:** `"Unknown genre"` ```conf name_unknown_genre = "" ``` - `name_unknown_composer` - Name of composer having an undefined name. **Default:** `"Unknown composer"` ```conf name_unknown_composer = "" ``` - `artwork_basenames` - List of base names for artwork files (file names without extension). **Note:** - OwnTone searches for JPEG and PNG files with these base names. - More information regarding artwork can be found [here](artwork.md). **Default:** `{ "artwork", "cover", "Folder" }` ```conf artwork_basenames = { "", "<...>" } ``` - `artwork_individual` - Flag to indicate whether or not the search for artwork corresponding to each individual media file must be done instead of only looking for the album artwork. **Notes:** - Disable this setting to reduce cache size. - More information regarding artwork can be found [here](artwork.md). **Default:** `false` ```conf artwork_individual = ``` - `artwork_online_sources` - List of online resources for artwork. **Notes:** - More information regarding artwork can be found [here](artwork.md). **Default:** unset ```conf artwork_online_sources = { "", "<...>"} ``` - `filetypes_ignore` - List of file types ignored by the scanner. **Note:** Non-audio files will never be added to the database, but here you can prevent the scanner from even probing them. This might reduce scan time. **Default:** `{ ".db", ".ini", ".db-journal", ".pdf", ".metadata" }` ```conf filetypes_ignore = { "", "<...>" } ``` - `filepath_ignore` - List of paths ignored by the scanner. **Note:** If you want to exclude files on a more advanced basis you can enter one or more POSIX regular expressions, and any file with a matching path will be ignored. **Default:** unset ```conf filepath_ignore = { "" } ``` - `filescan_disable` - Flag to indicate whether or not the startup file scanning must be disabled. **Note:** When OwnTone starts it will do an initial file scan of the library and then watch it for changes. If you are sure your library never changes while OwnTone is not running, you can disable the initial file scan and save some system ressources. Disabling this scan may lead to OwnTone's database coming out of sync with the library. If that happens read the instructions in the README on how to trigger a rescan. **Default:** `false` ```conf filescan_disable = ``` - `only_first_genre` - Flag to indicate whether or not the first genre only found in metadata must be displayed. **Note:** Some tracks have multiple genres separated by semicolon in the same tag, e.g., 'Pop;Rock'. If you don't want them listed like this, you can enable this setting and only the first genre will be used (i.e. 'Pop'). **Default:** `false` ```conf only_first_genre = ``` - `m3u_overrides` - Flag to indicate whether or not the metadata provided by radio streams must be overridden by metadata from m3u playlists, e.g., artist and title in EXTINF. **Default:** `false` ```conf m3u_overrides = ``` - `itunes_overrides` - Flag to indicate whether or not the library metadata must be overridden by iTunes metadata. **Default:** `false` ```conf itunes_overrides = ``` - `itunes_smartpl` - Flag to import Should we import the content of iTunes smart playlists. **Default:** `false` ```conf itunes_smartpl = ``` - `no_decode` - List of formats that are never decoded. **Note:** Decoding options for DAAP and RSP clients. Since iTunes has native support for mpeg, mp4a, mp4v, alac and wav, such files will be sent as they are. Any other formats will be decoded to raw wav. If OwnTone detects a non-iTunes DAAP client, it is assumed to only support mpeg and wav, other formats will be decoded. Here you can change when to decode. Note that these settings only affect serving media to DAAP and RSP clients, they have no effect on direct AirPlay, Chromecast and local audio playback **Valid values:** `mp4a`, `mp4v`, `mpeg`, `alac`, `flac`, `mpc`, `ogg`, `wma`, `wmal`, `wmav`, `aif`, `wav`. **Default:** unset ```conf no_decode = { "", "<...>" } ``` - `force_decode` - List of formats that are always decoded. **Note:** See note for `no_decode` setting. **Valid values:** `mp4a`, `mp4v`, `mpeg`, `alac`, `flac`, `mpc`, `ogg`, `wma`, `wmal`, `wmav`, `aif`, `wav`. **Default:** unset ```conf force_decode = { "", "<...>" } ``` - `prefer_format` - Preferred format to be used. **Default:** unset ```conf prefer_format = "" ``` - `decode_audio_filters` - List of audio filters used at decoding time. **Note:** These filters are ffmpeg filters: i.e. similar to those specified on the command line `ffmpeg -af `. Examples: `"volume=replaygain=track"` to use replay gain of the track metadata, or `loudnorm=I=-16:LRA=11:TP=-1.5` to normalise volume. **Default:** unset ```conf decode_audio_filters = { "" } ``` - `decode_video_filters` - List of video filters used at decoding time. **Note:** These filters are ffmpeg filters: i.e. similar to those specified on the command line `ffmpeg -vf `. **Default:** unset ```conf decode_video_filters = { "" } ``` - `pipe_autostart` - Flag to indicate whether or not named pipes must start automatically when data is provided. **Note:** To exclude specific pipes from watching, consider using the `filepath_ignore` setting. ```conf pipe_autostart = true ``` - `pipe_sample_rate` - Sampling rate of the pipe. **Default:** `44100`. ```conf pipe_sample_rate = ``` - `pipe_bits_per_sample` - Bits per sample of the pipe. **Default:** `16`. ```conf pipe_bits_per_sample = ``` - `rating_updates` - Flag to indicate whether or not ratings are automatically updated. **Note:** When enabled, the rating is automatically updated after a song has either been played or skipped (only skipping to the next song is taken into account). The calculation is taken from the beets plugin "mpdstats" (see [here](https://beets.readthedocs.io/en/latest/plugins/mpdstats.html)). It consists of calculating a stable rating based only on the play and skip count and a rolling rating based on the current rating and the action (played or skipped). Both results are combined with a mix factor of 0.75. **Formula:** new rating = 0.75 × stable rating + 0.25 × rolling rating **Default:** `false` ```conf rating_updates = ``` - `read_rating` - Flag to indicate whether or not the rating is read from media file metadata. **Default:** `false` ```conf read_rating = ``` - `write_rating` - Flag to indicate whether or not the rating is written back to the file metadata. **Note:** By default, ratings are only saved in the database. To avoid excessive writing to the library, automatic rating updates are not written, even with the write_rating setting enabled. **Default:** `false` ```conf write_rating = ``` - `max_rating` - Scale used when reading and writing ratings to media files. **Default:** `100` ```conf max_rating = ``` - `allow_modifying_stored_playlists` - Flag to indicate whether or not M3U playlists can be created, modified, or deleted in the playlist directories. **Note:** This setting is only supported through the web interface and some MPD clients. **Default:** `false` ```conf allow_modifying_stored_playlists = false ``` - `default_playlist_directory` - Name of the directory in one of the library directories that will be used as the default playlist directory. **Note:** OwnTone creates new playlists in this directory. This setting requires `allow_modify_stored_playlists` set to true. **Default:** unset ```conf default_playlist_directory = "" ``` - `clear_queue_on_stop_disable` - Flag to indicate whether or not the queue is cleared when the playback is stopped. **Note:** By default OwnTone will, like iTunes, clear the play queue if playback stops. Setting clear_queue_on_stop_disable to true will keep the playlist like MPD does. Moreover, some dacp clients do not show the play queue if playback is stopped. **Default:** `false` ```conf clear_queue_on_stop_disable = ``` ## Local Audio Settings ```conf audio { ... } ``` The `audio` section is meant to configure the local audio output. It accepts the settings below. - `nickname` - Name appearing in the speaker list. **Default:** `"Computer"` ```conf nickname = "Computer" ``` - `type` - Type of the output. **Valid values:** `alsa`, `pulseaudio`, `dummy`, `disabled` **Default:** unset ```conf type = "" ``` - `server` - For pulseaudio output, an optional server hostname or IP can be specified (e.g. "localhost").

If that is the case you are better off disabling the feature. **Default:** `false` ```conf sync_disable = ``` - `offset_ms` - Start delay in milliseconds relatively to other speakers, for example Airplay. **Note:** Negative values correspond to moving local audio ahead, positive correspond to delaying it. **Valid values:** -1000 to 1000 **Default:** `0` ```conf offset_ms = 0 ``` - `adjust_period_seconds` - Period in seconds used to collect measurements for drift and latency adjustments. **Note:** To calculate if resampling is required and if yes what value, local audio delay is measured each second. After a period the collected measurements are used to estimate drift and latency, which determines if corrections are required. **Default:** `100` ```conf adjust_period_seconds = ``` ## Per ALSA Device Settings ```conf alsa "" { } ``` Each `alsa` section is meant to configure a named ALSA output: one named section per device. It accepts the settings below. **Note:** Make sure to set the `""` correctly.
