Browser.element but with the ability to play sounds.

Browser.document but with the ability to play sounds.

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.

Note that in some browsers audio will be muted until user interacts with the webpage.

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.

Note that in some browsers audio will be muted until user interacts with the webpage.

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. 1 preserves the current volume, 0.5 halves it, and 0 mutes it. If the the volume is less than 0, 0 will be used instead.

Scale how loud some Audio is at different points in time. The volume will transition linearly between those points. The points in time don't need to be sorted but they need to be unique.

import Time




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