# Configuration

The configuration of OwnTone - usually located in `/etc/owntone.conf` - is split into multiple sections:

- `general` - Main settings of OwnTone.
- `library` - Settings of local library.
- `audio` - Settings for the local audio.
- `alsa` - Settings for ALSA devices.
- `fifo` - Settings for named pipe.
- `airplay_shared` - Settings shared across AirPlay devices.
- `airplay` - Settings for a specific AirPlay device.
- `chromecast` - Settings for a specific Chromecast device.
- `spotify` - Settings for the Spotify playback.
- `rcp` - Settings for RCP / Roku Soundbridge devices.
- `mpd` - Settings for MPD clients.
- `sqlite` - Settings for SQLite operation.
- `streaming` - Settings for the streaming.

## Format

Each section consists of a name enclosing settings within parentheses.

Each setting consists of a name and a value. There are different types of settings: string, integer, boolean, and list.

Comments are preceded by a hash sign.

The format is as follow:

    # Section
    section {
        # String value
        setting = "<string-value>"
        # Integer value
        setting = <integer-value>
        # Boolean
        setting = <true|false>
        # List
        setting = { "value a", "value b", "value n"}
    }

Note: For a regular use, the most important settings are:

- the `directories` (see `library` section), which should be the location of your media, and
- the `uid` (see `general` section), which must have read access to those directories.

## General Settings

    general {
      …
    }

The `general` section accepts the settings below.

Default: unset

    filepath_ignore = { "<path|regular-expression>" }

### 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`

    filescan_disable = <true|false>

### 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`

    only_first_genre = <true|false>

### m3u_overrides

### 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

Default: unset

    force_decode = { "<format>", "<...>" }

### prefer_format

Preferred format to be used.

Default: unset

    prefer_format = "<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 <filter>`. 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

    decode_audio_filters = { "<filter>" }

### 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 <filter>`.

Default: unset

    decode_video_filters = { "<filter>" }

### 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.

    pipe_autostart = true

### pipe_sample_rate

Sampling rate of the pipe.

Default: `44100`.

    pipe_sample_rate = <integer>

### pipe_bits_per_sample

Bits per sample of the pipe.

Default: `16`

    pipe_bits_per_sample = <integer>

### 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). 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`

    rating_updates = <true|false>

### read_rating

Flag to indicate whether or not the rating is read from media file metadata.

Default: `false`

    read_rating = <true|false>

### 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`

    write_rating = <true|false>

### max_rating

Scale used when reading and writing ratings to media files.

Default: `100`

    max_rating = <integer>

### allow_modifying_stored_playlists

Flag to indicate whether or not M3U playlists can be created, modified, or deleted in the playlist directories.

Default: `false`

    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

    default_playlist_directory = "<path-to-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`

    clear_queue_on_stop_disable = <true|false>

## Local Audio Settings

    audio {
      …

Note: Usable with ALSA only.

Default: unset

    mixer_device = "<mixer-device>"

### sync_disable

Flag to indicate whether or not audio resampling has to be enabled to keep local audio in sync with, for example, AirPlay.

Note: This feature relies on accurate ALSA measurements of delay, and some devices don't provide that. If that is the case you are better off disabling the feature.

Default: `false`

    sync_disable = <true|false>

### 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`

    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`

Flag indicating whether or not the power on the device is maintained.

Note: A Roku / SoundBridge can power up in 2 modes: (default) reconnect to the previously used library (i.e. OwnTone) or in a cleared library mode. The Roku power up behaviour is affected by how OwnTone disconnects from the Roku device. Set to false to maintain the default Roku power on behaviour.

Default: `false`

    clear_on_close = false

## MPD Settings

    mpd {
      …
    }

The `mpd` section defines the settings for MPD clients. It accepts the settings below.

Note: These settings only have effect if OwnTone is built with Spotify support.

## SQLite Settings

    sqlite {
      …
    }

The `sqlite` section defines how the SQLite database operates and accepts the settings below.
