An audio command.

Load audio from a url.

Possible errors we can get when loading audio files.

Audio data we can use to play sounds

Map a command from one type to another. Conceptually the same as Cmd.map

Combine multiple commands into a single command. Conceptually the same as Cmd.batch.

A command that does nothing. Conceptually the same as Cmd.none.

Some kind of sound we want to play. To create Audio start with audio.

Play audio from an audio source at a given time. This is the same as using audioWithConfig audioDefaultConfig.

Combine multiple Audios into a single Audio.

The sound of no sound at all.

Play audio from an audio source at a given time with config.

Default config used for audioWithConfig.

Extra settings when playing audio from a file.

-- Here we play a song at half speed and it skips the first 15 seconds of the song.
audioWithConfig
    { loop = Nothing
    , playbackRate = 0.5
    , startAt = Duration.seconds 15
    }
    myCoolSong
    songStartTime

Control how audio loops. loopEnd defines where (relative to the start of the audio) the audio should loop and loopStart defines where it should loop to.

-- Here we have a song that plays an intro once and then loops between the 10 second point and the end of the song.
let
    default =
        Audio.audioDefaultConfig


    -- This package doesn't support getting how long a sound plays for so we need to hard code it instead.
    songLength =
        Duration.seconds 120
in
audioWithConfig
    { default | loop = Just { loopStart = Duration.seconds 10, loopEnd = songLength } }
    coolBackgroundMusic
    startTime

Scale how loud a given Audio is. If the the volume is less than 0, 0 will be used instead.

Scale how loud a given Audio is at given points in time. The volume will transition linearly between those points.

-- Here we define a function that fades in audio to full volume and then fades it out until it's muted.

A nonempty list of (time, volume) points for defining how loud a sound should be at any point in time. The points don't need to be sorted but don't include multiple points that have the same time.
