The default behavior of howler.js is to attempt to silently unlock audio playback by playing an empty buffer on the first `touchend` event. This behavior can be disabled by calling: | ||
| ```javascript | ||
| Howler.iOSAutoEnable = false; | ||
| Howler.mobileAutoEnable = false; | ||
| ``` | ||
| ### Dolby Audio Playback | ||
| Full support for playback of the Dolby Audio format (currently support in Edge and Safari) is included. However, you must specify that the file you are loading is `dolby` since it is in a `mp4` container. | ||
| ```javascript | ||
| var dolbySound = new Howl({ | ||
| src: ['sound.mp4', 'sound.webm', 'sound.mp3'], | ||
| format: ['dolby', 'webm', 'mp3'] | ||
| }); | ||
| ``` | ||
| ### Format Recommendations | ||
| Howler.js supports a wide array of audio codecs that have varying browser support ("mp3", "opus", "ogg", "wav", "aac", "m4a", "mp4", "weba", ...), but if you want full browser coverage you still need to use at least two of them. If your goal is to have the best balance of small filesize and high quality, based on extensive production testing, your best bet is to default to `ogg/webm` and fallback to `mp3`. Both `ogg` and `webm` have nearly full browser coverage with a great combination of compression and quality. You'll need the `mp3` fallback for Internet Explorer. | ||

| It is important to remember that howler.js selects the first compatible sound from your array of sources. So if you want `ogg` or `webm` to be used before `mp3`, you need to put the sources in that order. | ||

| If you want your `webm` files to be seekable in Firefox, be sure to encode them with the cues element. One way to do this is by using the `dash` flag in [ffmpeg](https://www.ffmpeg.org/): | ||
| ``` | ||
| ffmpeg -i sound1.wav -dash 1 sound1.webm | ||
