Different audio apps often have unique requirements. For example, when a navigator app speaks driving instructions, a music player should duck its audio while a podcast player should pause its audio.

If you are building a podcast player or audio book reader, this behaviour would not be appropriate. While the user may be able to comprehend the navigator instructions while ducked music is playing in the background, it would be much more difficult to understand the navigator instructions while simultaneously listening to an audio book or podcast. + +You can use the [audio_session](https://pub.dev/packages/audio_session) package to change the default audio session configuration for your app. E.g. for a podcast player, you may use: + +```dart +final session = await AudioSession.instance; +await session.configure(AudioSessionConfiguration.speech()); +``` + +Note: If your app uses a number of different audio plugins, e.g. for audio recording, or text to speech, or background audio, it is possible that those plugins may internally override each other's audio session settings, so it is recommended that you apply your own preferred configuration using audio_session after all other audio plugins have loaded.
