+A few aspects of Element Call's interface can be controlled through a global API on the `window`.
+
+## Picture-in-picture
 
 - `controls.canEnterPip(): boolean` Determines whether it's possible to enter picture-in-picture mode.
 - `controls.enablePip(): void` Puts the call interface into picture-in-picture mode. Throws if not in a call.
 - `controls.disablePip(): void` Takes the call interface out of picture-in-picture mode, restoring it to its natural display mode. Throws if not in a call.
+
+## Audio devices
+
+On mobile platforms (iOS, Android), web views do not reliably support selecting audio output devices such as the main speaker, earpiece, or headset. To address this limitation, the following functions allow the hosting application (e.g., Element Web, Element X) to manage audio devices via exposed JavaScript interfaces. These functions must be enabled using the URL parameter `controlledAudioDevices` to take effect.
+
+- `controls.setAvailableAudioDevices(devices: { id: string, name: string, forEarpiece?: boolean, isEarpiece?: boolean isSpeaker?: boolean, isExternalHeadset?, boolean; }[]): void` Sets the list of available audio outputs. `forEarpiece` is used on iOS only.
+  It flags the device that should be used if the user selects earpiece mode. This should be the main stereo loudspeaker of the device.
+- `controls.onAudioDeviceSelect: ((id: string) => void) | undefined` Callback called whenever the user or application selects a new audio output.
+- `controls.setAudioDevice(id: string): void` Sets the selected audio device in Element Call's menu. This should be used if the OS decides to automatically switch to Bluetooth, for example.
+- `controls.setAudioEnabled(enabled: boolean)` Enables/disables all audio output from the application. Output is enabled by default.
+- `controls.onAudioPlaybackStarted: ((id: string) => void) | undefined`: This will be called the first time we start
+  playing audio in the webview. It can be helpful to do device setup on the native app when the webviews audio is ready.
+  In particular android is using it to setup the output channel so that the call volume can
+  be controlled by the hardware volume rocker.
+
+## Element Call button delegation
+
+Callbacks for buttons in EC that are handled by the native application
+
+- `showNativeAudioDevicePicker: (() => void) | undefined`. Callback called whenever the user presses the output button in the settings menu.
+  This button is only shown on iOS. (`/iPad|iPhone|iPod|Mac/.test(navigator.userAgent)`)
+- `onBackButtonPressed: (() => void) | undefined`. Callback when the webview detects a tab on the header's back button.
